Ukudalwa kwesiseko se-IT esinyamezelayo. Icandelo 2. Ukufakela kunye nokuqwalasela i-oVirt 4.3 cluster

Eli nqaku liqhubeka nelangaphambili - “Ukwenziwa kweziseko ezingundoqo ze-IT ezinokunyamezela iimpazamo. Icandelo 1 - ulungiselela ukusasaza i-oVirt 4.3 cluster».

Iza kujongana nenkqubo yofakelo olusisiseko kunye nolungiselelo lweqela le-oVirt 4.3 ukulungiselela ukusingatha oomatshini abafumaneka kakhulu, kuthathelwa ingqalelo into yokuba onke amanyathelo okuqala okulungiselela iziseko zophuhliso sele egqitywe ngaphambili.

Inxalenye yokwazisa

Eyona njongo yenqaku kukubonelela ngemiyalelo yenyathelo nenyathelo efana ne “Okulandelayo -> Ewe -> Gqiba"indlela yokubonisa ezinye iimpawu xa uyifaka kwaye uyiqwalasela. Inkqubo yokuhambisa i-cluster yakho ayinakuhlala ihambelana naleyo ichazwe kuyo, ngenxa yeempawu zesiseko kunye nokusingqongileyo, kodwa imigaqo jikelele iya kufana.

Ukusuka kwimbono ezimeleyo, oVirt 4.3 ukusebenza kwayo iyafana VMware vSphere version 5.x, kodwa kunjalo kunye noqwalaselo kunye nokusebenza iimpawu zayo.

Kwabo banomdla, zonke iiyantlukwano phakathi kweRHEV (aka oVirt) kunye neVMware vSphere inokufumaneka kwi-Intanethi, umzekelo. apha, kodwa ngamanye amaxesha ndiya kuphawula ukungafani kwazo okanye ukufana kwazo njengoko inqaku liqhubeka.

Ngokwahlukileyo, ndingathanda ukuthelekisa kancinci umsebenzi kunye neenethiwekhi zoomatshini ababonakalayo. I-oVirt isebenzisa umgaqo ofanayo wolawulo lwenethiwekhi koomatshini benyani (emva koku kubhekiselwa kubo njenge-VMs), njengakwiVMware vSphere:

• usebenzisa ibhulorho yeLinux eqhelekileyo (kwiVMware - I-vSwitch eqhelekileyo), esebenza kwiinginginya zokubonwayo;
• usebenzisa Vula i-vSwitch (OVS) (kwiVMware - Ukuhanjiswa kwe-vSwitch) lutshintsho lwenyani olusasazwayo olubandakanya amacandelo amabini aphambili: iseva ye-OVN ephakathi kunye nabalawuli be-OVN kwimikhosi elawulwayo.

Kufuneka kuqatshelwe ukuba ngenxa yokulula kokuphunyezwa, inqaku liza kuchaza ukuseta amanethiwekhi kwi-oVirt ye-VM usebenzisa ibhulorho ye-Linux eqhelekileyo, eyona nto ikhethiweyo xa usebenzisa i-hypervisor ye-KVM.

Kule nkalo, kukho imigaqo emininzi esisiseko yokusebenza kunye nenethiwekhi kwiqela, eyona nto ingcono ukuba ingaphulwa:

• Zonke iisetingi zenethiwekhi kwiinginginya phambi kokuba zongezwe kwi-oVirt kufuneka zifane, ngaphandle kweedilesi ze-IP.
• Nje ukuba inginginya ithathwe phantsi kolawulo lwe-oVirt, ayikhuthazwa kakhulu ukuba utshintshe nantoni na ngesandla kwiisetingi zenethiwekhi ngaphandle kokuzithemba okupheleleyo kwizenzo zakho, kuba iarhente ye-oVirt iya kuziqengqelekela nje kwezi zangaphambili emva kokuqalisa kwakhona umkhosi okanye iarhente.
• Ukongeza inethiwekhi entsha ye-VM, kunye nokusebenza nayo, kufuneka yenziwe kuphela kwi-oVirt yolawulo lwekhonsoli.

Enye inqaku elibalulekileyo - kwindawo ebaluleke kakhulu (enovakalelo kakhulu kwilahleko yemali), kuseza kucetyiswa ukuba kusetyenziswe inkxaso ehlawulwayo kunye nokusetyenziswa. I-Red Hat Virtualization 4.3. Ngexesha lokusebenza kweqela le-oVirt, eminye imiba inokuvela apho kuyacetyiswa ukuba ufumane uncedo olufanelekileyo ngokukhawuleza, kunokuba ujongane nayo ngokwakho.

Kwaye ekugqibeleni icetyisiwe Phambi kokuba usebenzise iqela le-oVirt, ziqhelanise nalo amaxwebhu asemthethweni, ukwenzela ukuba uqaphele ubuncinane iingcamango ezisisiseko kunye neenkcazo, ngaphandle koko kuya kuba nzima ukufunda lonke inqaku.

Okusisiseko ekuqondeni inqaku kunye nemigaqo yokusebenza kweqela le-oVirt ngala maxwebhu esisikhokelo:

• Isikhokelo soFakelo lwe-oVirt
• oVirt Self-Hosted Engine Guide
• Isikhokelo soLawulo lwe-oVirt
  

Umthamo apho awukho mkhulu kakhulu, kwiyure okanye ezimbini unokuyilawula kakuhle imigaqo esisiseko, kodwa kwabo bathanda iinkcukacha, kuyacetyiswa ukuba bayifunde. Uxwebhu lweMveliso yeRed Hat Virtualization 4.3 — I-RHEV kunye ne-oVirt ziyinto enye.

Ngoko ke, ukuba zonke izicwangciso ezisisiseko kwimikhosi, utshintsho kunye neenkqubo zokugcina zigqityiwe, siqhubeka ngokuthe ngqo ekuhanjisweni kwe-oVirt.

Icandelo 2. Ukufakela kunye nokuqwalasela i-oVirt 4.3 cluster

Ukuze kube lula ukuziqhelanisa, ndiza kudwelisa amacandelo aphambili kweli nqaku, ekufuneka ligqitywe nganye nganye:

1. Ukuhlohla iseva yolawulo lwe-oVirt
2. Ukwenziwa kweziko elitsha ledatha
3. Ukudala iqela elitsha
4. Ukufakela iinginginya ezongezelelweyo kwindawo yokuZibamba
5. Ukudala indawo yokugcina okanye iiNdawo zokuGcina
6. Ukudala kunye nokuqwalasela uthungelwano koomatshini benyani
7. Ukwenza umfanekiso wofakelo wokuhambisa umatshini obonakalayo
8. Yenza umatshini wenyani

Ukuhlohla iseva yolawulo lwe-oVirt

iseva yolawulo lwe-oVirt yeyona nto ibalulekileyo kwisiseko se-oVirt, ngokohlobo lomatshini wenyani, umamkeli, okanye isixhobo esinenyani esilawula yonke isiseko se-oVirt.

Ii-analogues zayo ezisondeleyo ezivela kwihlabathi le-virtualization zezi:

• VMware vSphere - vCenter Server
• IMicrosoft Hyper-V - Umphathi Woomatshini Wokubonwa Kwenkqubo (VMM).

Ukufakela iseva yolawulo lwe-oVirt, sinokukhetha ezimbini:

Ikhetho 1
Ukusasaza iseva ngohlobo lwe-VM ekhethekileyo okanye umamkeli.

Olu khetho lusebenza kakuhle, kodwa ngaphandle kokuba i-VM enjalo isebenza ngokuzimeleyo kwiqela, okt. ayisebenzi kuyo nayiphi na inginginya yeqela njengomatshini oqhelekileyo onenyani oqhuba i-KVM.

Kutheni le nto i-VM enjalo ingenakubekwa kwiinginginya zeqela?

Kwasekuqaleni kwenkqubo yokuthumela iseva yolawulo lwe-oVirt, sinengxaki - kufuneka sifake i-VM yolawulo, kodwa enyanisweni akukho qela ngokwalo okwangoku, kwaye ke yintoni esinokuza nayo ngokubhabha? Kulungile - faka i-KVM kwi-node yeqela elizayo, emva koko udale umatshini obonakalayo kuyo, umzekelo, kunye ne-CentOS OS kwaye usebenzise injini ye-oVirt kuyo. Oku kunokwenziwa ngezizathu zolawulo olupheleleyo kwi-VM enjalo, kodwa le yimpazamo, kuba kulo mzekelo, kwixesha elizayo kuya kubakho iingxaki nge-100% yolawulo olunjalo lwe-VM:

• ayinakufuduswa kwi-oVirt console phakathi kweenginginya (iindawo zokuhlala) zeqela;
• xa ufuduka usebenzisa i-KVM nge ivirsh iyafuduka, le VM ayizukufumaneka kulawulo olusuka kwi-oVirt console.
• Inginginya zeqela azinakuboniswa Imowudi yogcino (indlela yogcino), ukuba ufudusa le VM ukusuka kumamkeli ukuya kumamkeli usebenzisa ivirsh iyafuduka.

Ngoko yenza yonke into ngokwemigaqo - sebenzisa nokuba ngumamkeli owahlukileyo kumncedisi wolawulo we-oVirt, okanye iVM ezimeleyo esebenza kuyo, okanye ngcono noko, yenza njengoko kubhaliwe kukhetho lwesibini.

Ikhetho 2
Ukufakela i-oVirt Engine Appliance kwi-cluster host elawulwa yiyo.

Olu khetho luya kuqwalaselwa ngakumbi njengento echanekileyo kwaye ifanelekile kwimeko yethu.
Iimfuno ze-VM ezinjalo zichazwe ngezantsi, ndiya kongeza kuphela ukuba kuyacetyiswa ukuba kubekho iinginginya ezimbini ubuncinane kwiziseko ezingundoqo apho i-VM yolawulo inokuqhutywa khona ukuze ikwazi ukunyamezela iimpazamo. Apha ndingathanda ukongeza ukuba, njengoko sele ndibhale kwizimvo kwinqaku elidlulileyo, andizange ndikwazi ukufumana i-splitbrain kwiqela le-oVirt leenginginya ezimbini, ekwaziyo ukuqhuba ii-VM ze-injini ebanjwe kuzo.

Ukufakela i-oVirt Engine Appliance kwinginginya yokuqala yeqela

Ikhonkco kumaxwebhu asemthethweni - oVirt Self-Hosted Engine Guide, isahluko "Ukusasaza Injini Yokuzibamba Ngokusebenzisa Umgca Womyalelo»

Uxwebhu luchaza izinto ezifunekayo ekufuneka zifezekiswe ngaphambi kokuthunyelwa kwe-injini ye-hosted-VM, kwaye ichaza ngokweenkcukacha inkqubo yofakelo ngokwayo, ngoko ke akukho nto incinci yokuyiphinda ngokwezwi nezwi, ngoko ke siya kugxininisa kwiinkcukacha ezibalulekileyo.

• Ngaphambi kokuba uqalise zonke izenzo, qiniseka ukuba uvumela inkxaso ye-virtualization kwiisetingi zeBIOS kumamkeli.
• Faka ipakethe yesifakeli se-injini esisingethweyo kumamkeli:

yum -y install http://resources.ovirt.org/pub/yum-repo/ovirt-release43.rpm 
yum -y install epel-release
yum install screen ovirt-hosted-engine-setup

• Siqala inkqubo yokubeka i-oVirt Honji ye-injini kwisikrini kumamkeli (unokuyiphuma nge-Ctrl-A + D, vala nge-Ctrl-D):

screen
hosted-engine --deploy

Ukuba uyanqwenela, ungaqhuba ufakelo ngefayile yempendulo elungiselelwe kwangaphambili:

hosted-engine --deploy --config-append=/var/lib/ovirt-hosted-engine-setup/answers/answers-ohe.conf

• Xa uhambisa injini ebanjwe, sichaza zonke iiparameters eziyimfuneko:

- имя кластера
- количество vCPU и vRAM (рекомендуется 4 vCPU и 16 Гб)
- пароли
- тип хранилища для hosted engine ВМ – в нашем случае FC
- номер LUN для установки hosted engine
- где будет находиться база данных для hosted engine – рекомендую для простоты выбрать Local (это БД PostgreSQL работающая внутри этой ВМ)
и др. параметры. 

• Ukufakela i-VM efumanekayo kakhulu kunye ne-injini ebanjwe, ngaphambili sakha i-LUN ekhethekileyo kwinkqubo yokugcina, inombolo ye-4 kunye ne-150 GB ngobukhulu, eyathi yanikezelwa kwimikhosi yeqela - bona inqaku elidlulileyo.

Ngaphambili siphinde sajonga ukubonakala kwayo kubabuthi:

multipath -ll
…

  `- 18:0:0:4  sdj 8:144 active ready running

• Inkqubo yokusasazwa kwe-injini yokusingatha ngokwayo ayintsonkothanga ekugqibeleni kufuneka sifumane into efana nale:

[ INFO  ] Generating answer file '/var/lib/ovirt-hosted-engine-setup/answers/answers-20191129131846.conf'
[ INFO  ] Generating answer file '/etc/ovirt-hosted-engine/answers.conf'
[ INFO  ] Stage: Pre-termination

Sijonga ubukho beenkonzo ze-oVirt kumamkeli:

Ukuba yonke into yenziwe ngokuchanekileyo, emva kokuba ukufakela kugqityiwe, sebenzisa i-browser yewebhu ukuya kuyo https://ovirt_hostname/ovirt-engine ukusuka kwikhompyuter yomphathi, kwaye ucofe [Ulawulo lwePortal].

Umfanekiso weskrini "kwiNdawo yoLawulo"

Ngokufaka igama lokungena kunye negama lokugqitha (ekusetweni ngexesha lofakelo) kwifestile njengoko kumfanekiso wekhusi, sifika kwindawo yolawulo evulekileyo yoManejala weVirtualization, apho unokwenza zonke iintshukumo ngesiseko esibonakalayo:

1. yongeza iziko ledatha
2. yongeza kwaye uqwalasele iqela
3. yongeza kwaye ulawule iinginginya
4. yongeza iindawo zokugcina okanye IiNdawo zoGcino kwiidiski zomatshini wenyani
5. Yongeza kwaye uqwalasele uthungelwano loomatshini benyani
6. yongeza kwaye ulawule oomatshini benyani, ukufakela imifanekiso, iitemplates zeVM

Zonke ezi zenzo ziya kuxoxwa ngakumbi, ezinye kwiiseli ezinkulu, ezinye kwiinkcukacha ezithe kratya kunye nee-nuances.
Kodwa okokuqala ndingacebisa ukuba kufundwe esi songezo, esiya kuba luncedo kwabaninzi.

Yongeza

1) Ngokomgaqo, ukuba kukho imfuno enjalo, ke akukho nto ikuthintelayo ekufakeni i-hypervisor ye-KVM kwi-cluster nodes kwangaphambili usebenzisa iipakethi. libvirt и qemu-kvm (okanye qemu-kvm-ev) yoguqulelo olufunwayo, nangona xa usebenzisa indawo yeqela le-oVirt, ingayenza ngokwayo.

Kodwa ukuba libvirt и qemu-kvm Ukuba awuyifakelanga inguqulelo yamva nje, ungafumana le mpazamo ilandelayo xa usebenzisa injini ebanjwe:

error: unsupported configuration: unknown CPU feature: md-clear

Ezo. okufuneka ubenazo inguqulelo ehlaziyiweyo libvirt ngokhuseleko kwi MDS, exhasa lo mgaqo-nkqubo:

<feature policy='require' name='md-clear'/>

Faka i-libvirt v.4.5.0-10.el7_6.12, ngenkxaso ecacileyo ye-md:

yum-config-manager --disable mirror.centos.org_centos-7_7_virt_x86_64_libvirt-latest_

yum install centos-release-qemu-ev
yum update
yum install qemu-kvm qemu-img virt-manager libvirt libvirt-python libvirt-client virt-install virt-viewer libguestfs libguestfs-tools dejavu-lgc-sans-fonts virt-top libvirt libvirt-python libvirt-client

systemctl enable libvirtd
systemctl restart libvirtd && systemctl status libvirtd

Jonga inkxaso ye-'md-clear':

virsh domcapabilities kvm | grep require
      <feature policy='require' name='ss'/>
      <feature policy='require' name='hypervisor'/>
      <feature policy='require' name='tsc_adjust'/>
      <feature policy='require' name='clflushopt'/>
      <feature policy='require' name='pku'/>
      <feature policy='require' name='md-clear'/>
      <feature policy='require' name='stibp'/>
      <feature policy='require' name='ssbd'/>
      <feature policy='require' name='invtsc'/>

Emva koku, unokuqhubeka nokufaka injini ebanjwe.

2) Kwi-oVirt 4.3, ubukho kunye nokusetyenziswa kwe-firewall umlilo yimfuneko enyanzelekileyo.

Ukuba ngexesha lokusasazwa kwe-VM kwi-injini ebanjwe sifumana le mpazamo ilandelayo:

[ ERROR ] fatal: [localhost]: FAILED! => {"changed": false, "msg": "firewalld is required to be enabled and active in order to correctly deploy hosted-engine. Please check, fix accordingly and re-deploy.n"}
[ ERROR ] Failed to execute stage 'Closing up': Failed executing ansible-playbook
[https://bugzilla.redhat.com/show_bug.cgi?id=1608467

Emva koko kufuneka ucime enye i-firewall (ukuba isetyenzisiwe), kwaye ufake kwaye usebenze umlilo:

yum install firewalld
systemctl enable firewalld
systemctl start firewalld

firewall-cmd --state
firewall-cmd --get-default-zone
firewall-cmd --get-active-zones
firewall-cmd --get-zones

Kamva, xa ufaka i-arhente ye-ovirt kwinginginya entsha yeqela, iya kuqwalasela izibuko ezifunekayo umlilo ngokuzenzekelayo.

3) Ukuqalisa kwakhona umamkeli ngeVM esebenza kuyo ngenjini ebanjwe.

Njengesiqhelo, ikhonkco 1 и ikhonkco 2 kumaxwebhu olawulo.

Lonke ulawulo lwe-injini yokusingatha i-VM lwenziwa KUPHELA kusetyenziswa umyalelo i-injini yokusingatha kwinginginya apho ibaleka khona, malunga umtshana kufuneka silibale, kunye nenyaniso yokuba ungaqhagamshela kule VM nge-SSH kwaye usebenzise umyalelo "Cima».

Inkqubo yokubeka i-VM kwindlela yokulondoloza:

hosted-engine --vm-shutdown

Siphinda siqalise umamkeli nge-arhente ye-injini ebanjwe kwaye senze into esiyifunayo ngayo.

Emva kokuqalisa kwakhona, jonga imeko ye-VM ngenjini ebanjwe:

hosted-engine --vm-status

Ukuba i-VM yethu ene-injini ebanjiwe ayiqalisi kwaye ukuba sibona iimpazamo ezifanayo kwilog yenkonzo:

Imposiso kwilog yenkonzo:

hosted-engine --connect-storage
systemctl restart ovirt-ha-agent
systemctl status ovirt-ha-agent

hosted-engine --vm-start
hosted-engine --vm-status

Emva kokuqala i-VM nge-injini ebanjwe, siyikhupha kwindlela yokulondoloza:

Inkqubo yokususa i-VM kwindlela yokulondoloza:

4) Ukususa injini ebanjwe nayo yonke into ehambelana nayo.

Ngamanye amaxesha kuyimfuneko ukususa ngokufanelekileyo injini ebifakwe ngaphambili - unxibelelwano kuxwebhu lwesikhokelo.

Qhuba nje umyalelo kumamkeli:

/usr/sbin/ovirt-hosted-engine-cleanup

Okulandelayo, sisusa iipakethe ezingeyomfuneko, sixhasa ezinye iinkqubo phambi koku, ukuba kuyimfuneko:

yum autoremove ovirt* qemu* virt* libvirt* libguestfs 

Ukwenziwa kweziko elitsha ledatha

Amaxwebhu ezalathiso-iSikhokelo soLawulo lwe-oVirt. Isahluko 4: Amaziko eenkcukacha

Okokuqala makhe sichaze ukuba yintoni na iziko ledatha (Ndicaphula kuncedo) liqumrhu elinengqiqo elichaza isethi yemithombo esetyenziswa kwindawo ethile.

Iziko ledatha luhlobo lwesikhongozeli esibandakanya:

• izixhobo ezinengqiqo ngohlobo lwamaqela kunye nababuki zindwendwe
• Izixhobo zothungelwano lweqela ngendlela yothungelwano olunengqiqo kunye neeadaptha ezibonakalayo kwiinginginya,
• izixhobo zokugcina (kwiidiski zeVM, iitemplates, imifanekiso) ngendlela yeendawo zokugcina (IiNdawo zokuGcina).

Iziko ledatha lingabandakanya amaqela amaninzi aquka imikhosi emininzi kunye noomatshini abasebenzayo abasebenzayo kubo, kwaye ingaba neendawo ezininzi zokugcina ezinxulumene nayo.
Kunokubakho amaziko amaninzi edatha asebenza ngokuzimeleyo omnye komnye. I-Ovirt inokwahlulwa kwamagunya ngendima, kwaye unokuqwalasela iimvume zodwa, zombini kwinqanaba leziko ledatha nakwizinto zalo ezinengqondo.

Iziko ledatha, okanye amaziko edatha ukuba kukho ezininzi zazo, zilawulwa kwi-console eyodwa yolawulo okanye i-portal.

Ukwenza iziko ledatha, yiya kwi-portal yolawulo kwaye wenze iziko elitsha ledatha:
Qhawula >> Amaziko eDatha >> New

Kuba sisebenzisa ugcino olwabelwanayo kwinkqubo yokugcina, Uhlobo loGcino kufuneka kwabelwane ngalo:

Umfanekiso weskrini weWizard yeNdalo yeDatha

Xa ufaka umatshini wenyani onenjini ebanjwe, iziko ledatha lenziwa ngokungagqibekanga - Iziko ledatha1, kwaye ke, ukuba kuyimfuneko, ungalutshintsha udidi lwayo lokuGcina kwenye.

Ukudala isikhungo sedatha ngumsebenzi olula, ngaphandle kwanoma yimaphi ama-nuances akhohlisayo, kwaye zonke izenzo ezongezelelweyo kunye nazo zichazwe kumaxwebhu. Ekuphela kwento endiya kuyiqaphela kukuba iinginginya ezingatshatanga ezinokugcinwa kwendawo kuphela (idiski) ye-VMs aziyi kukwazi ukungena kwiziko ledatha kunye noHlobo lokuGcina - eKwabelwana ngalo (azinakongezwa apho), kwaye kubo kufuneka ubenzele. iziko ledatha eyahlukileyo - i.e. Inginginya nganye enokugcinwa kwendawo ifuna indawo yayo eyahlukileyo yedatha.

Ukudala iqela elitsha

Ikhonkco kumaxwebhu - Isikhokelo soLawulo lwe-oVirt. Isahluko 5: Amaqela

Ngaphandle kweenkcukacha ezingafunekiyo, iklasta - eli liqela elinengqiqo lemikhosi enendawo yokugcina indawo eqhelekileyo (ngendlela yeediski ezabelwana ngazo kwisistim sokugcina, njengoko kunjalo kwimeko yethu). Kukwanqweneleka ukuba iinginginya ezikwiqela zifane kwihardware kwaye zibe nohlobo olufanayo lweprosesa (Intel okanye AMD). Kungcono, ngokuqinisekileyo, ukuba abancedisi kwiqela bafana ngokupheleleyo.

Iqela liyinxalenye yeziko ledatha (kunye nohlobo oluthile lokugcina - weNgingqi okanye Kwabiwe), kwaye yonke inginginya kufuneka ibe yeyohlobo oluthile lweqela, kuxhomekeke ekubeni babelane ngogcino okanye hayi.

Xa ufaka umatshini wenyani onenjini ebanjwe kwinginginya, iziko ledatha lenziwa ngokungagqibekanga - Iziko ledatha1, kunye neqela - Iqela1, kwaye kwixesha elizayo ungaqwalasela iiparameters zayo, yenza iinketho ezongezelelweyo, yongeza iinginginya kuyo, njl.

Njengesiqhelo, malunga neenkcukacha malunga nazo zonke izicwangciso ze-cluster, kuyacetyiswa ukuba ubhekisele kumaxwebhu asemthethweni. Kweminye yeempawu zokuseta iqela, ndiyakongeza kuphela ukuba xa uyidala, kwanele ukuqwalasela kuphela iiparitha ezisisiseko kwithebhu. ngokubanzi.

Ndiza kuqaphela ezona parameters zibalulekileyo:

• Uhlobo lweprosesa - ikhethiweyo ngokusekelwe kwiziphi iiprosesa ezifakwe kwi-host hosts, yintoni umenzi avela kuyo, kwaye yeyiphi iprosesa kwimikhosi eyona indala, ukwenzela ukuba, kuxhomekeke kule nto, yonke imiyalelo ekhoyo yeprosesa kwiqela isetyenziswa.
• Tshintsha uhlobo Kwiqela lethu sisebenzisa ibhulorho yeLinux kuphela, yiyo loo nto siyikhethayo.
• Uhlobo lwe-Firewall - yonke into icacile apha, le yi-firewalld, ekufuneka yenziwe kwaye iqwalaselwe kwiinginginya.

Ukudala indawo yokugcina okanye iiNdawo zokuGcina

Ikhonkco kumaxwebhu-Isikhokelo soLawulo lwe-oVirt, Isahluko 8: Ugcino.

Indawo yogcino, okanye indawo yokugcina, yindawo esembindini yokugcina iidiski zomatshini wenyani, imifanekiso yofakelo, itemplates, kunye nesnapshots.

Iindawo zokugcina zinokudityaniswa kwiziko ledatha usebenzisa iiprotocol ezahlukeneyo, iqoqo kunye neenkqubo zeefayile zenethiwekhi.

I-oVirt ineendidi ezintathu zendawo yokugcina:

• Ummandla weDatha -ukugcina yonke idatha ehambelana noomatshini benyani (iidiski, iitemplates). I-Data Domain ayinakwabelwana phakathi kwamaziko ahlukeneyo edatha.
• ISO Domain (uhlobo oluphelelweyo lwendawo yokugcina) - yokugcina imifanekiso yofakelo lwe-OS. I-ISO Domain inokwabelwana ngayo phakathi kwamaziko ahlukeneyo edatha.
• Thumela ngaphandle Domain (uhlobo oluphelelweyo lwendawo yokugcina) - ukugcinwa kwesikhashana kwemifanekiso ehanjiswe phakathi kwamaziko edatha.

Kwimeko yethu ethile, indawo yokugcina kunye nohlobo lweDatha yeDatha isebenzisa iProtocol yeFiber Channel (FCP) ukuxhuma kwii-LUNs kwinkqubo yokugcina.

Ukusuka kwindawo yokujonga i-oVirt, xa usebenzisa iinkqubo zokugcina (FC okanye iSCSI), idiski nganye ebonakalayo, i-snapshot okanye itemplate yidiski enengqiqo.
Izixhobo zokuvala zidityaniswa zibe yiyunithi enye (kwinginginya zeqela) kusetyenziswa iVolume Group kwaye zahlulwe kusetyenziswa i-LVM ibe yimithamo esengqiqweni, esetyenziswa njengediski yenyani yeeVM.

Onke la maqela kunye nemiqulu emininzi yeLVM inokubonwa kwinginginya yeqela usebenzisa imiyalelo njl и lvs. Ngokwemvelo, zonke izenzo ezineediski ezinjalo kufuneka zenziwe kuphela kwi-console ye-oVirt, ngaphandle kweemeko ezizodwa.

Iidiski ezibonakalayo zee-VM zinokuba ziindidi ezimbini - QCOW2 okanye RAW. Iidiski zinokuba "bhityile"okanye"ngqindilili". Izifinyezo zihlala ziyilwa njenge "bhityile".

Indlela yokulawula imimandla yoGcino, okanye iindawo zokugcina ezifikelelweyo ngeFC, isengqiqweni - kwidiski yeVM nganye kukho umthamo owahlukileyo onengqondo obhalwa ngumamkeli omnye kuphela. Kuqhagamshelo lweFC, i-oVirt isebenzisa into efana ne-LVM edibeneyo.

Oomatshini bokwenyani ababekwe kwindawo enye yogcino banokufuduswa phakathi kwenginginya ezizeqela elinye.

Njengoko sibona kwinkcazo, iqela kwi-oVirt, njengeqela kwi-VMware vSphere okanye i-Hyper-V, ngokusisiseko lithetha into enye - liqela elinengqiqo leenginginya, ngokukhethekayo lifana nokwakhiwa kwehardware, kunye nokugcinwa okuqhelekileyo kwenyani. iidiski zoomatshini.

Masiqhubeke ngokuthe ngqo ekudaleni indawo yokugcina idatha (iidiski ze-VM), kuba ngaphandle kwayo iziko ledatha aliyi kuqaliswa.
Makhe ndikukhumbuze ukuba zonke ii-LUN ezinikezelwe kwiinginginya zeqela kwindlela yokugcina kufuneka zibonakale kuzo usebenzisa umyalelo "iindlela ezininzi -ll».

Ngokutsho amaxwebhu, yiya kwi portal yiya ku yoGcino >> amathambeka -> Ummandla omtsha kwaye ulandele imiyalelo evela kwicandelo "Ukongeza i-FCP Storage".

Emva kokuqalisa iwizard, gcwalisa iindawo ezifunekayo:

• igama — seta igama leqela
• Domain Function —Idatha
• Uhlobo logcino -IFiber Channel
• Umamkeli oza Kusetyenziswa — khetha umamkeli apho iLUN esiyifunayo ifumaneka khona

Kuluhlu lwee-LUNs, phawula leyo esiyifunayo, cofa Yongeza kwaye emva koko Lungile. Ukuba kuyimfuneko, unokulungelelanisa iiparamitha ezongezelelweyo zendawo yokugcina ngokunqakraza Iiparameter eziPhambili.

Umfanekiso weskrini wewizadi yokongeza "isizinda soGcino"

Ngokusekelwe kwiziphumo zewizadi, kufuneka sifumane indawo yokugcina entsha, kwaye isikhungo sethu sedatha kufuneka sihambe kwisimo UP, okanye iqaliswe:

Izikrini zeziko ledatha kunye neendawo zokugcina kuyo:

Ukudala kunye nokuqwalasela uthungelwano koomatshini benyani

Ikhonkco kumaxwebhu-Isikhokelo soLawulo lwe-oVirt, Isahluko 6: Uthungelwano oluQinisekayo

Uthungelwano, okanye uthungelwano, lusebenza kwiqela lothungelwano oluqiqiweyo olusetyenziswa kwiziseko ezingundoqo ze-oVirt.

Ukunxibelelana phakathi kweadaptha yenethiwekhi kumatshini obonakalayo kunye neadaptha ebonakalayo kumamkeli, ujongano olunengqiqo olufana nebhulorho yeLinux luyasetyenziswa.

Ukwenza iqela kunye nokwahlula i-traffic phakathi kothungelwano, iiVLAN ziqwalaselwe kwiiswitshi.

Xa usenza uthungelwano olunengqiqo koomatshini benyani kwi-oVirt, kufuneka inikwe isazisi esihambelana nenombolo yeVLAN ekutshintsheni ukuze ii-VM zikwazi ukunxibelelana nabanye, nokuba ziqhuba kwiindawo ezahlukeneyo zeqela.

Iisetingi zokuqala zeeadaptha zothungelwano kwiinginginya zokuqhagamshela koomatshini benyani kwafuneka zenziwe inqaku elidlulileyo – ujongano olusengqiqweni luqwalaselwe bond1, ngoko zonke izicwangciso zenethiwekhi kufuneka zenziwe kuphela nge-oVirt yolawulo portal.

Emva kokudala i-VM ene-injini ebanjwe, ukongeza ekudaleni ngokuzenzekelayo iziko ledatha kunye neqela, inethiwekhi enengqiqo yenziwe ngokuzenzekelayo ukulawula iqela lethu - ovritmgmt, apho le VM yadityaniswa khona.

Ukuba kuyimfuneko, unokujonga useto lwenethiwekhi olunengqiqo ovritmgmt kwaye uzilungelelanise, kodwa kufuneka ulumke ungaphulukani nolawulo lwesiseko se-oVirt.

Izicwangciso zenethiwekhi ezisengqiqweni ovritmgmt

Ukwenza uthungelwano olutsha olunengqiqo kwii-VM eziqhelekileyo, kwi-portal yolawulo yiya ku womnatha >> IiNethiwekhi >> New, kunye nethebhu ngokubanzi yongeza inethiwekhi nge-ID yeVLAN efunwayo, kwaye ujonge ibhokisi ecaleni kwe “Uthungelwano lweVM", oku kuthetha ukuba ingasetyenziselwa isabelo kwi-VM.

Umfanekiso weskrini wenethiwekhi entsha ye-VLAN32 enengqiqo

Kwithebhu Iqela, sincamathela le nethiwekhi kwiqela lethu Iqela1.

Emva koko sibuyela Qhawula >> Amakhaya, yiya kumamkeli ngamnye ngokulandelelana, kwisithuba Ujongano lwenethiwekhi, kwaye uqalise iwizard Cwangcisa iinethiwekhi zomamkeli, ukubophelela kwiinginginya zenethiwekhi entsha enengqiqo.

Umfanekiso wekhusi wewizadi "Seta ii-host host networks".

I-agent ye-oVirt iya kwenza ngokuzenzekelayo zonke izicwangciso zenethiwekhi eziyimfuneko kwi-host host - yenza i-VLAN kunye ne-BRIDGE.

Umzekelo weefayile zoqwalaselo zenethiwekhi ezintsha kumamkeli:

cat ifcfg-bond1
# Generated by VDSM version 4.30.17.1

Makhe ndikukhumbuze kwakhona ukuba kwi-cluster host AKUKHO MFUNEKO yenza ujongano lwenethiwekhi ngesandla kwangaphambili ifcfg-bond1.432 и ifcfg-ovirtvm-vlan432.

Emva kokongeza inethiwekhi enengqiqo kwaye ukhangele uxhulumaniso phakathi komninimzi kunye ne-injini ye-VM ebanjwe, inokusetyenziswa kumatshini wenyani.

Ukwenza umfanekiso wofakelo wokuhambisa umatshini obonakalayo

Ikhonkco kumaxwebhu-Isikhokelo soLawulo lwe-oVirt, Isahluko 8: Ugcino, icandelo Lokufaka iMifanekiso kwiNdawo yokuGcina iDatha.

Ngaphandle komfanekiso wofakelo lwe-OS, akunakwenzeka ukufaka umatshini wenyani, nangona oku akuyongxaki ukuba, umzekelo, ifakwe kwinethiwekhi. I-Cobbler ngemifanekiso eyenziwe kwangaphambili.

Kwimeko yethu, oku akunakwenzeka, ke kuya kufuneka ungenise lo mfanekiso kwi-oVirt ngokwakho. Ngaphambili, oku bekufuna ukudala i-ISO Domain, kodwa kwinguqulelo entsha ye-oVirt iye yarhoxiswa, kwaye ke ngoku unokulayisha imifanekiso ngokuthe ngqo kwi-domain yoGcino kwi-portal yolawulo.

Kwi-portal yolawulo yiya ku yoGcino >> Disks >> Upload >> Qala
Songeza umfanekiso wethu we-OS njengefayile ye-ISO, gcwalisa onke amasimi kwifom, kwaye ucofe iqhosha "Uqhagamshelo lovavanyo".

Umfanekiso wekhusi we Dibanisa iWizard yoMfanekiso woFakelo

Ukuba sifumana impazamo efana nale:

Ikhonkco loxwebhu:
I-oVirt Isikhokelo soLawulo loMatshini weVirt-> Isahluko 2: Ukufakela oomatshini beLinux Virtual
Izibonelelo zabathengi beConsole

Emva kokulayisha umfanekiso wofakelo nge-OS kwi-oVirt, ungaqhubeka ngokuthe ngqo ekudaleni umatshini obonakalayo. Mninzi umsebenzi osele wenziwe, kodwa sele sikwinqanaba lokugqibela, ngenxa yoko konke oku kwaqalwa-ukufumana isiseko esinyamezelayo sokusingatha oomatshini abafumaneka kakhulu. Kwaye konke oku kusimahla - akukho nepeni enye echithwe ekuthengeni naziphi na iilayisensi zesoftware.

Ukwenza umatshini wenyani kunye ne-CentOS 7, umfanekiso wokufakela kwi-OS kufuneka ukhutshelwe.

Siya kwi-portal yolawulo, yiya ku Qhawula >> Oomatshini ababonakalayo, kwaye uqalise iWizard yokudala yeVM. Gcwalisa zonke iiparameters kunye namasimi kwaye ucofe Lungile. Yonke into ilula kakhulu ukuba ulandela uxwebhu.

Njengomzekelo, ndiza kunika isiseko kunye neseto ezongezelelweyo zeVM efumaneka kakhulu, enediski eyenziweyo, eqhagamshelwe kwinethiwekhi, kunye nokuqala kumfanekiso wofakelo:

Iiskrini ezineseto zeVM ezifumanekayo kakhulu

Emva kokugqiba umsebenzi kunye ne-wizard, yivale, uqalise i-VM entsha kwaye ufake i-OS kuyo.
Ukwenza oku, yiya kwi-console yale VM ngokusebenzisa i-portal yolawulo:

Umfanekiso wekhusi wezicwangciso zeportal yolawulo yokuqhagamshela kwiVM console

Ukuqhagamshela kwi-console ye-VM, kufuneka uqale uqwalasele i-console kwiipropati zomatshini wenyani.

Umfanekiso weskrini we-VM useto, "Console" ithebhu

Ukuqhagamshela kwiVM console ungasebenzisa, umzekelo, IsiBoneleli soomatshini esibonakalayo.

Ukuqhagamshela kwi-console ye-VM ngokuthe ngqo kwi-browser yefestile, izicwangciso zoqhagamshelwano nge-console kufuneka zibe ngolu hlobo lulandelayo:

Emva kokufaka i-OS kwi-VM, kuyacetyiswa ukuba ufake i-oVirt iarhente yeendwendwe:

yum -y install epel-release
yum install -y ovirt-guest-agent-common
systemctl enable ovirt-guest-agent.service && systemctl restart ovirt-guest-agent.service
systemctl status ovirt-guest-agent.service

Ngaloo ndlela, ngenxa yezenzo zethu, i-VM eyakhiwe iya kufumaneka kakhulu, i.e. ukuba indawo yeqela esebenza kuyo ayiphumeleli, i-oVirt iyakuyiqalisa kwakhona ngokuzenzekelayo kwindawo yesibini. Le VM isenokufuduswa phakathi kobukista beqela ukulungiselela ugcino lwabo okanye ezinye iinjongo.

isiphelo

Ndiyathemba ukuba eli nqaku likwazile ukuhambisa ukuba i-oVirt sisixhobo esiqhelekileyo sokulawula iziseko ezingundoqo, okungekho nzima kakhulu ukuzisebenzisa - into ephambili kukulandela imigaqo ethile kunye neemfuno ezichazwe kwinqaku kunye nakumaxwebhu.

Ngenxa yomthamo omkhulu wenqaku, kwakungenakwenzeka ukubandakanya izinto ezininzi kuyo, njengokwenziwa kwenyathelo ngenyathelo le-wizards ehlukeneyo kunye nazo zonke iinkcazo ezicacileyo kunye nezikrini, izigqibo ezide zeminye imiyalelo, njl. Ngapha koko, oku kuya kufuna ukubhala incwadi yonke, engenzi ngqiqo kangako ngenxa yeenguqulelo ezintsha zesoftware ezihlala zivela ngezinto ezintsha kunye notshintsho. Eyona nto ibaluleke kakhulu kukuqonda umgaqo wendlela yonke esebenza ngayo kunye, kunye nokufumana i-algorithm eqhelekileyo yokudala iqonga elinokunyamezela impazamo lokulawula oomatshini bokwenene.

Nangona senze isiseko esibonakalayo, ngoku kufuneka siyifundise ukusebenzisana phakathi kwezinto zayo ezizimeleyo: iinginginya, oomatshini ababonakalayo, uthungelwano lwangaphakathi, kunye nelizwe langaphandle.

Le nkqubo ngomnye wemisebenzi ephambili yenkqubo okanye umlawuli womnatha, eya kugutyungelwa kwinqaku elilandelayo - malunga nokusetyenziswa kweerotha zeVyOS kwisiseko sokunyamezela impazamo yeshishini lethu (njengoko uqikelele, baya kusebenza njengenyani. oomatshini kwiqela lethu le-oVirt).
