🥇Ukwakhiwa kwengqalasizinda ye-IT ekwazi ukumelana namaphutha. Ingxenye 2. Ukufaka nokumisa iqoqo le-oVirt 4.3

Lesi sihloko siwukuqhutshekwa kwedlule - “Ukwakhiwa kwengqalasizinda ye-IT ekwazi ukumelana namaphutha. Ingxenye 1 - Ukulungiselela Ukuphakela I-oVirt 4.3 Cluster".

Izohlanganisa inqubo yokufaka nokuhlela okuyisisekelo kweqoqo le-oVirt 4.3 lokusingatha imishini ebonakalayo etholakala kakhulu, kucatshangelwa iqiniso lokuthi zonke izinyathelo zokuqala zokulungiselela ingqalasizinda bese ziqediwe ngaphambilini.

Isingeniso

Inhloso enkulu ye-athikili ukunikeza imiyalelo yesinyathelo nesinyathelo njengokuthi “Olandelayo -> Yebo -> Qeda"ungabonisa kanjani ezinye izici lapho uyifaka futhi uyilungiselela. Inqubo yokukhipha iqoqo lakho ingase ingahlali iqondana nalokho okuchazwe kuyo, ngenxa yezimpawu zengqalasizinda nendawo ezungezile, kodwa imigomo evamile izofana.

Ngokombono we-subjective, oVirt 4.3 ukusebenza kwayo kufana nenguqulo ye-VMware vSphere 5.x, kodwa vele inezici zayo zokucushwa nokusebenza.

Kulabo abanentshisekelo, wonke umehluko phakathi kwe-RHEV (aka oVirt) ne-VMware vSphere ingatholakala ku-inthanethi, isibonelo. lapha, kodwa ngezinye izikhathi ngisazophawula okunye ukuhlukana kwazo noma ukufana kwazo njengoba isihloko siqhubeka.

Ngokwehlukana, ngingathanda ukuqhathanisa kancane umsebenzi namanethiwekhi emishini ebonakalayo. I-oVirt isebenzisa umgomo ofanayo wokuphathwa kwenethiwekhi emishinini ebonakalayo (ngemuva kwalokhu ebizwa ngokuthi ama-VM), njengaku-VMware vSphere:

usebenzisa ibhuloho elijwayelekile le-Linux (ku-VMware - I-vSwitch ejwayelekile), esebenza kubasingathi be-virtualization;
usebenzisa i-Open vSwitch (OVS) (ku-VMware - I-vSwitch esabalalisiwe) iyiswishi ebonakalayo esabalalisiwe ehlanganisa izingxenye ezimbili eziyinhloko: iseva ye-OVN emaphakathi nezilawuli ze-OVN kubabungazi abaphethwe.

Kufanele kuqashelwe ukuthi ngenxa yokusebenziseka kalula, i-athikili izochaza ukusetha amanethiwekhi ku-oVirt ye-VM kusetshenziswa ibhuloho elijwayelekile le-Linux, okuyisinqumo esijwayelekile uma usebenzisa i-hypervisor ye-KVM.

Kulokhu, kunemithetho eminingana eyisisekelo yokusebenza nenethiwekhi kuqoqo, okungcono kakhulu ukuthi ingaphulwa:

Zonke izilungiselelo zenethiwekhi kubasingathi ngaphambi kokubangeza ku-oVirt kufanele zifane, ngaphandle kwamakheli e-IP.
Uma umsingathi esethathwe ngaphansi kolawulo lwe-oVirt, akunconywa kakhulu ukuthi uguqule noma yini mathupha kuzilungiselelo zenethiwekhi ngaphandle kokuzethemba okuphelele ezenzweni zakho, ngoba i-ejenti ye-oVirt izovele iwabuyisele kwedlule ngemuva kokuqalisa kabusha umsingathi noma umenzeli.
Ukwengeza inethiwekhi entsha ye-VM, kanye nokusebenza ngayo, kufanele kwenziwe kuphela ku-oVirt management console.

Okunye inothi elibalulekile - endaweni ebucayi kakhulu (ezwela kakhulu ekulahlekelweni kwemali), kusazonconywa ukuthi kusetshenziswe ukwesekwa okukhokhelwayo nokusetshenziswa I-Red Hat Virtualization 4.3. Ngesikhathi sokusebenza kweqoqo le-oVirt, ezinye izinkinga zingase ziphakame lapho kungakuhle ukuthi uthole usizo olufanele ngokushesha ngangokunokwenzeka, kunokuba ubhekane nazo ngokwakho.

Futhi ekugcineni kunconyiwe Ngaphambi kokuthi usebenzise iqoqo le-oVirt, zijwayeze imibhalo esemthethweni, ukuze uqaphele okungenani imiqondo nezincazelo eziyisisekelo, ngaphandle kwalokho kuyoba nzima ukufunda sonke isihloko.

Okuyisisekelo ekuqondeni i-athikili kanye nemigomo yokusebenza kweqoqo le-oVirt yile mibhalo yokuqondisa:

Ivolumu lapho ayinkulu kakhulu, ngehora noma amabili ungakwazi kahle izimiso eziyisisekelo, kodwa kulabo abathanda imininingwane, kunconywa ukufunda Imibhalo Yomkhiqizo Ye-Red Hat Virtualization 4.3 - I-RHEV ne-oVirt empeleni ziyinto efanayo.

Ngakho-ke, uma zonke izilungiselelo eziyisisekelo kubasingathi, amaswishi nezinhlelo zokugcina seziqediwe, siqhubekela ngqo ekufakweni kwe-oVirt.

Ingxenye 2. Ukufaka nokulungisa iqoqo le-oVirt 4.3

Ukuze kube lula ukuqondiswa, ngizobhala izigaba eziyinhloko kulesi sihloko, okumele zigcwaliswe ngayinye ngayinye:

Ifaka iseva yokuphatha i-oVirt
Ukwakhiwa kwesikhungo sedatha esisha
Idala iqoqo elisha
Ukufaka ababungazi abengeziwe endaweni yokuzisingatha ngokwakho
Ukudala indawo yokugcina noma Izizinda Zesitoreji
Ukudala nokulungiselela amanethiwekhi emishini ebonakalayo
Ukudala isithombe sokufaka sokuphakela umshini obonakalayo
Ukudala umshini obonakalayo

Ifaka iseva yokuphatha i-oVirt

Iseva yokuphathwa kwe-oVirt - lena into ebaluleke kakhulu engqalasizinda ye-oVirt, esesimweni somshini obonakalayo, umsingathi, noma idivayisi ebonakalayo elawula yonke ingqalasizinda ye-oVirt.

Ama-analogues aseduze avela emhlabeni we-virtualization yilezi:

I-VMware vSphere - Iseva ye-vCenter
I-Microsoft Hyper-V - Umphathi Womshini Obonakalayo Wesikhungo Sesistimu (VMM).

Ukufaka iseva yokuphatha ye-oVirt, sinezinketho ezimbili:

Inketho ye-1
Ithumela iseva ngendlela ye-VM ekhethekile noma umsingathi.

Le nketho isebenza kahle kakhulu, kodwa inqobo nje uma i-VM enjalo isebenza ngokuzimela ngaphandle kweqoqo, i.e. ayisebenzi kunoma iyiphi i-cluster host njengomshini ojwayelekile osebenzisa i-KVM.

Kungani i-VM enjalo ingakwazi ukuthunyelwa kubasingathi beqoqo?

Ekuqaleni kwenqubo yokuthumela iseva yokuphatha ye-oVirt, sinenkinga - sidinga ukufaka i-VM yokuphatha, kodwa empeleni alikho iqoqo ngokwalo okwamanje, ngakho-ke yini esingaqhamuka nayo ngokuhamba kwesikhathi? Kulungile - faka i-KVM endaweni ye-cluster yesikhathi esizayo, bese udala umshini obonakalayo kuyo, isibonelo, nge-CentOS OS bese ufaka injini ye-oVirt kuyo. Lokhu ngokuvamile kungenziwa ngezizathu zokulawula okuphelele kwe-VM enjalo, kodwa lokhu kuyinhloso eyiphutha, ngoba kulokhu, esikhathini esizayo kuyoba nezinkinga ezingu-100% nge-VM yokulawula enjalo:

ayikwazi ukuthuthwa kukhonsoli ye-oVirt phakathi kwabasingathi (amanodi) eqoqo;
lapho ufuduka usebenzisa i-KVM nge i-virsh iyafuduka, le VM ngeke itholakalele ukuphathwa ku-oVirt console.
abasingathi beqoqo abakwazi ukuboniswa phakathi Imodi yesondlo (imodi yesondlo), uma uthutha le VM kusuka kumsingathi uye kosokhaya usebenzisa i-virsh iyafuduka.

Ngakho-ke yenza yonke into ngokwemithetho - sebenzisa i-host host ehlukile yeseva yokuphatha i-oVirt, noma i-VM ezimele esebenza kuyo, noma okungcono, yenza njengoba kubhaliwe kunketho yesibili.

Inketho ye-2
Ukufaka i-oVirt Engine Appliance kumsingathi weqoqo eliphethwe yilo.

Yile nketho ezobhekwa njengelungile futhi ifaneleka esimweni sethu.
Izidingo ze-VM enjalo zichazwe ngezansi; ngizokwengeza kuphela ukuthi kuyanconywa ukuthi okungenani kube nabasingathi ababili kungqalasizinda lapho i-VM yokulawula ingaqhutshwa khona ukuze ikwazi ukubekezelela amaphutha. Lapha ngithanda ukungeza ukuthi, njengoba ngibhale kakade kumazwana esihlokweni esandulele, angizange ngikwazi ukuthola i-splitbrain kuqoqo le-oVirt labasingathi ababili, abanekhono lokusebenzisa ama-VM enjini ephethwe kubo.

Ukufaka i-oVirt Engine Appliance kumsingathi wokuqala weqoqo

Isixhumanisi semibhalo esemthethweni - I-oVirt Self-Hosted Engine Guide, isahluko "Ukuthumela Injini Ezimele Ngokusebenzisa umugqa womyalo»

Umbhalo ucacisa izimfuneko okufanele kuhlangatshezwane nazo ngaphambi kokuthumela i-VM yenjini esingethwe, futhi ichaza ngokuningiliziwe inqubo yokufaka ngokwayo, ngakho-ke akukho phuzu lokuyiphinda izwi nezwi, ngakho-ke sizogxila kweminye imininingwane ebalulekile.

Ngaphambi kokuqala zonke izenzo, qiniseka ukunika amandla ukusekelwa kwe-virtualization kuzilungiselelo ze-BIOS kumsingathi.
Faka iphakheji yesifaki senjini esingethwe kumsingathi:

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 inqubo yokufaka i-oVirt Hosting Engine esikrinini kumsingathi (ungayiphuma ngo-Ctrl-A + D, vala nge-Ctrl-D):

screen
hosted-engine --deploy

Uma uthanda, ungaqalisa ukufaka ngefayela lempendulo elilungiselelwe kusengaphambili:

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

Lapho kuthunyelwa injini ephethwe, sicacisa wonke amapharamitha adingekayo:

- 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.

Ukufaka i-VM etholakala kakhulu ngenjini esingethwe, ngaphambilini sakha i-LUN ekhethekile ohlelweni lokugcina, inombolo engu-4 no-150 GB ngosayizi, eyabe yethulwa kubasingathi beqoqo - bheka isihloko esandulele.

Ngaphambilini siphinde sahlola ukubonakala kwayo kubabungazi:

multipath -ll

Sibheka ubukhona bezinsizakalo ze-oVirt kumsingathi:

Uma konke kwenziwe ngendlela efanele, emva kokufakwa kuqediwe, sebenzisa isiphequluli sewebhu ukuze uye kuso https://ovirt_hostname/ovirt-engine kusuka kukhompuyutha yomlawuli, bese uchofoza [Iphothali Yokuphatha].

Isithombe-skrini se-“Administration Portal”

Ngokufaka ukungena nephasiwedi (okusethwe ngesikhathi sokufaka) efasiteleni njengasesithombeni-skrini, sifika kuphaneli yokulawula ye-Open Virtualization Manager, lapho ungenza khona zonke izenzo nengqalasizinda ebonakalayo:

engeza isikhungo sedatha
engeza futhi ulungiselele iqoqo
engeza futhi uphathe ababungazi
engeza izindawo zokugcina noma Izizinda Zesitoreji zamadiski emishini ebonakalayo
engeza futhi ulungiselele amanethiwekhi emishini ebonakalayo
engeza futhi uphathe imishini ebonakalayo, izithombe zokufaka, izifanekiso ze-VM

Zonke lezi zenzo kuzoxoxwa ngazo ngokuqhubekayo, ezinye kumaseli amakhulu, ezinye ngokuningiliziwe kanye nama-nuances.
Kodwa okokuqala ngingancoma ukufunda lesi sengezo, okungenzeka sibe usizo kwabaningi.

Ukwengeza

1) Eqinisweni, uma kunesidingo esinjalo, akukho lutho olukuvimbela ukuthi ufake i-KVM hypervisor kuma-cluster node kusengaphambili usebenzisa amaphakheji. libvirt и qemu-kvm (noma qemu-kvm-ev) yenguqulo efiswayo, nakuba lapho kuthunyelwa i-oVirt cluster node, ingakwenza lokhu ngokwayo.

Kepha uma libvirt и qemu-kvm Uma ungakafaki inguqulo yakamuva, ungathola iphutha elilandelayo lapho ukhipha injini esingethwe:

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

Labo. kumele ube nayo inguqulo ebuyekeziwe libvirt ngesivikelo kusuka MDS, esekela le nqubomgomo:

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

Faka i-libvirt v.4.5.0-10.el7_6.12, ngosekelo lwe-md-clear:

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

Bheka usekelo lwe-'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'/>

Ngemva kwalokhu, ungaqhubeka nokufaka injini esingethwe.

2) Ku-oVirt 4.3, ukuba khona kanye nokusetshenziswa kwe-firewall i-firewalld kuyisidingo esiyisibopho.

Uma ngesikhathi sokuthunyelwa kwe-VM yenjini esingethwe sithola iphutha elilandelayo:

[ 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

Khona-ke udinga ukucisha enye i-firewall (uma isetshenziswa), bese uyifake futhi uyisebenzise i-firewalld:

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

Kamuva, lapho ufaka i-ovirt ejenti kumsingathi omusha weqoqo, izomisa izimbobo ezidingekayo ku-cluster. i-firewalld ngokuzenzakalelayo.

3) Iqalisa kabusha umsingathi nge-VM esebenza kuyo ngenjini esingethwe.

Njengenjwayelo, isixhumanisi 1 и isixhumanisi 2 kumadokhumenti abusayo.

Konke ukuphathwa kwenjini ephethwe i-VM kwenziwa KUPHELA kusetshenziswa umyalo injini ephethwe kumsingathi lapho igijima khona, cishe Virsh kufanele sikhohlwe, kanye neqiniso lokuthi ungakwazi ukuxhuma kule VM nge-SSH futhi usebenzise umyalo “vala shaqa".

Inqubo yokufaka i-VM kumodi yokulungisa:

Siqalisa kabusha umsingathi ngomenzeli wenjini esingethwe futhi senze esikudingayo ngayo.

Ngemva kokuqalisa kabusha, hlola isimo se-VM ngenjini esingethwe:

hosted-engine --vm-status

Uma i-VM yethu ene-hosted-injini ingaqali futhi uma sibona amaphutha afanayo kulogi yesevisi:

Iphutha kulogi yesevisi:

4) Ukususa injini esingethwe nakho konke okuhlotshaniswa nayo.

Kwesinye isikhathi kuyadingeka ukususa kahle injini ephethwe ngaphambilini efakwe - isixhumanisi kudokhumenti yokuqondisa.

Vele usebenzise umyalo kumsingathi:

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

Okulandelayo, sisusa amaphakheji angadingekile, sisekela ezinye izilungiselelo ngaphambi kwalokhu, uma kunesidingo:

yum autoremove ovirt* qemu* virt* libvirt* libguestfs

Ukwakhiwa kwesikhungo sedatha esisha

Imibhalo eyinkomba - Umhlahlandlela Wokuphatha we-oVirt. Isahluko 4: Izikhungo Zedatha

Okokuqala ake sichaze ukuthi kuyini isikhungo sedatha (Ngicaphuna osizweni) yibhizinisi elinengqondo elichaza isethi yezinsiza ezisetshenziswa endaweni ethile.

Isikhungo sedatha siwuhlobo lwesiqukathi esihlanganisa:

izinsiza ezinengqondo ngendlela yamaqoqo nabasingathi
izinsiza zenethiwekhi yeqoqo ngendlela yamanethiwekhi anengqondo nama-adaptha aphathekayo kubasingathi,
izinsiza zokugcina (zamadiski e-VM, izifanekiso, izithombe) ngendlela yezindawo zokugcina (Izizinda Zesitoreji).

Isikhungo sedatha singabandakanya amaqoqo amaningi ahlanganisa abasingathi abaningi abanemishini ebonakalayo esebenza kuzo, futhi singaba nezindawo eziningi zokugcina ezihlobene naso.
Kungaba khona izikhungo zedatha ezimbalwa; zisebenza ngokuzimela ngaphandle kwesinye. I-Ovirt inokuhlukaniswa kwamandla ngendima, futhi ungakwazi ukumisa izimvume ngazinye, kokubili ezingeni lesikhungo sedatha nasezicini zayo ezingazodwana ezinengqondo.

Isikhungo sedatha, noma izikhungo zedatha uma kukhona ezimbalwa zazo, ziphathwa kusukela kukhonsoli eyodwa yokuphatha noma iphothali.

Ukuze udale isikhungo sedatha, hamba kuphothali yokuphatha bese udala isikhungo sedatha esisha:
Qondanisa >> Amasevisi Emininingwane >> New

Njengoba sisebenzisa isitoreji esabiwe ohlelweni lwesitoreji, Uhlobo Lwesitoreji kufanele Kwabiwe:

Isithombe-skrini Seseluleki Sokudala Sesikhungo Sedatha

Lapho ufaka umshini obonakalayo onenjini ephethwe, isikhungo sedatha sidalwa ngokuzenzakalelayo - Isikhungo sedatha1, bese, uma kunesidingo, ungashintsha Uhlobo lwayo Lwesitoreji uye kolunye.

Ukudala isikhungo sedatha kuwumsebenzi olula, ongenawo ama-nuances akhohlisayo, futhi zonke izenzo ezengeziwe ezihambisana naso zichazwe embhalweni. Ukuphela kwento engizoyiqaphela ukuthi abasingathi abangabodwa abanesitoreji sendawo kuphela (idiski) yama-VM ngeke bakwazi ukungena esikhungweni sedatha esinohlobo Lwesitoreji - Kwabiwe (azinakwengezwa lapho), futhi kubo udinga ukubenzela isikhungo sedatha esihlukile - i.e. Umsingathi ngamunye onesitoreji sasendaweni udinga isikhungo sakhe sedatha esihlukile.

Idala iqoqo elisha

Xhumanisa nemibhalo - Umhlahlandlela Wokuphatha we-oVirt. Isahluko 5: Amaqoqo

Ngaphandle kwemininingwane engadingekile, iqoqo - lokhu kuyiqoqo elinengqondo lababungazi abanendawo yokugcina evamile (ngesimo samadiski abiwe ohlelweni lwesitoreji, njengakithi). Kuyafiseleka futhi ukuthi ababungazi kuqoqo bafane ngehadiwe futhi babe nohlobo olufanayo lwephrosesa (Intel noma AMD). Kuhle kakhulu, vele, ukuthi amaseva kuqoqo afane ngokuphelele.

Iqoqo liyingxenye yesikhungo sedatha (nohlobo oluthile lokugcina - Local noma Kwabiwe), futhi bonke ababungazi kufanele babe bohlobo oluthile lweqoqo, kuye ngokuthi banesitoreji esabiwe noma cha.

Lapho ufaka umshini we-virtual onenjini ephethwe kumsingathi, isikhungo sedatha sidalwa ngokuzenzakalelayo - Isikhungo sedatha1, kanye neqoqo - Iqoqo1, futhi esikhathini esizayo ungamisa imingcele yayo, unike amandla izinketho ezengeziwe, ungeze ababungazi kuyo, njll.

Njengenjwayelo, ukuze uthole imininingwane mayelana nazo zonke izilungiselelo zeqoqo, kuyancomeka ukuthi ubhekisele kumadokhumenti asemthethweni. Kwezinye zezici zokusetha iqoqo, ngizongeza kuphela ukuthi uma udala, kwanele ukulungisa kuphela imingcele eyisisekelo kuthebhu. General.

Ngizoqaphela amapharamitha abaluleke kakhulu:

Uhlobo lweprosesa - ikhethwa ngokusekelwe ekutheni yimaphi amaphrosesa afakwe kubasingathi beqoqo, ukuthi bavela kumuphi umkhiqizi, futhi yimuphi umprosesa kumahosti omdala kunawo wonke, ukuze, kuye ngalokhu, yonke imiyalelo etholakalayo yephrosesa ku-cluster isetshenziswa.
Shintsha uhlobo - kuqoqo lethu sisebenzisa ibhuloho le-Linux kuphela, yingakho silikhetha.
Uhlobo lwe-firewall - yonke into icacile lapha, lena i-firewalld, okumele inikwe amandla futhi ilungiselelwe kubasingathi.

Isithombe-skrini esinamapharamitha eqoqo

Ukufaka ababungazi abengeziwe endaweni yokuzisingatha ngokwakho

Izikhombo ukuze kubhalwe phansi.

Ababungazi abengeziwe bendawo Yokusingatha Ngokwakho bengezwa ngendlela efanayo nomsingathi ovamile, ngesinyathelo esengeziwe sokuphakela i-VM ngenjini esingethwe - Khetha isenzo sokuthunyelwa kwenjini esisingethwe >> Sebenzisa. Njengoba umsingathi owengeziwe kufanele futhi ethulwe nge-LUN ye-VM enenjini esingethwe, lokhu kusho ukuthi lo msingathi angakwazi, uma kunesidingo, ukusetshenziselwa ukusingatha i-VM enenjini esingethwe kuyo.
Ngezinjongo zokubekezelela amaphutha, kunconywa kakhulu ukuthi kube khona okungenani abasingathi ababili lapho kungabekwa khona injini ephethwe i-VM.

Kosokhaya owengeziwe, khubaza ama-iptables (uma enikwe amandla), nika amandla i-firewalld

systemctl stop iptables
systemctl disable iptables

systemctl enable firewalld
systemctl start firewalld

Faka inguqulo ye-KVM edingekayo (uma kunesidingo):

Isithombe-skrini esinamapharamitha "Wokuphatha Amandla" ezindaweni zokusingatha

Ukudala indawo yokugcina noma Izizinda Zesitoreji

Xhumanisa nemibhalo - Umhlahlandlela Wokuphatha we-oVirt, Isahluko 8: Isitoreji.

Isizinda Sesitoreji, noma indawo yokugcina, iyindawo emaphakathi yokugcina amadiski emishini ebonakalayo, izithombe zokufakwa, izifanekiso, nezifinyezo.

Izindawo zokugcina zingaxhunywa esikhungweni sedatha kusetshenziswa amaphrothokholi ahlukahlukene, iqoqo kanye nezinhlelo zamafayela enethiwekhi.

I-oVirt inezinhlobo ezintathu zendawo yokugcina:

Isizinda Sedatha - ukugcina yonke idatha ehlobene nemishini ebonakalayo (amadiski, izifanekiso). Isizinda Sedatha asinakwabelwa ngaso phakathi kwezikhungo zedatha ezihlukene.
Isizinda se-ISO (uhlobo oluphelelwe yisikhathi lwendawo yokugcina) - yokugcina izithombe zokufakwa kwe-OS. Isizinda se-ISO singabiwa phakathi kwezikhungo zedatha ezahlukahlukene.
Thumela Isizinda (uhlobo oluphelelwe yisikhathi lwendawo yokugcina) - ukugcinwa kwesikhashana kwezithombe ezihanjiswe phakathi kwezikhungo zedatha.

Esimeni sethu esithile, indawo yokugcina enohlobo lwe-Data Domain isebenzisa i-Fiber Channel Protocol (FCP) ukuze ixhume kuma-LUN ohlelweni lokugcina.

Ngokombono we-oVirt, lapho usebenzisa izinhlelo zokugcina (FC noma iSCSI), idiski ngayinye ebonakalayo, isifinyezo noma ithempulethi iyidiski enengqondo.
Imishini yokuvimba ihlanganiswa ibe yiyunithi eyodwa (kubasingathi beqoqo) kusetshenziswa iVolume Group bese ihlukaniswa kusetshenziswa i-LVM ibe amavolumu anengqondo, asetshenziswa njengamadiski abonakalayo ama-VM.

Wonke lawa maqembu kanye namavolumu amaningi e-LVM angabonwa kumsingathi weqoqo kusetshenziswa imiyalo njll и lvs. Ngokwemvelo, zonke izenzo ezinamadiski anjalo kufanele zenziwe kuphela ku-oVirt console, ngaphandle kwezimo ezikhethekile.

Amadiski abonakalayo wama-VM angaba yizinhlobo ezimbili - QCOW2 noma RAW. Amadiski angaba "mncane"noma"obukhulu". Izifinyezo zihlala zidalwa njenge-"mncane".

Indlela yokuphatha izizinda zeSitoreji, noma izindawo zokugcina ezifinyelelwa nge-FC, inengqondo impela - kudiski ebonakalayo ye-VM ngayinye kunevolumu enengqondo ehlukile ebhalwa umsingathi oyedwa kuphela. Ekuxhumekeni kwe-FC, i-oVirt isebenzisa into efana ne-LVM ehlanganisiwe.

Imishini ebonakalayo etholakala endaweni efanayo yokugcina ingathuthwa phakathi kwababungazi beqoqo elifanayo.

Njengoba singabona encazelweni, iqoqo ku-oVirt, njengeqoqo ku-VMware vSphere noma i-Hyper-V, empeleni lisho into efanayo - liyiqoqo elinengqondo lababungazi, okungcono lifane ekwakhiweni kwehadiwe, futhi libe nesitoreji esivamile sokubona. amadiski omshini.

Masiqhubekele ngqo ekudaleni indawo yokugcina idatha (amadiski e-VM), ngoba ngaphandle kwayo isikhungo sedatha ngeke siqaliswe.
Ake ngikukhumbuze ukuthi wonke ama-LUN ethulwa kubasingathi beqoqo kusistimu yokugcina kufanele abonakale kubo kusetshenziswa umyalo othi “izindlela eziningi -ll".

Ngokusho imibhalo, hamba uye kuphothali uye ku Storage >> Domains -> Isizinda Esisha bese ulandela imiyalelo evela esigabeni esithi "Ukwengeza Isitoreji Se-FCP".

Ngemva kokuqalisa iwizadi, gcwalisa izinkambu ezidingekayo:

Igama — setha igama leqoqo
Umsebenzi Wesizinda - Idatha
Uhlobo Lwesitoreji - I-Fiber Channel
Umsingathi ozosetshenziswa — khetha umphathi lapho i-LUN esiyidingayo itholakala kuye

Ohlwini lwama-LUN, maka leyo esiyidingayo, chofoza Engeza bese Kulungile. Uma kunesidingo, ungalungisa imingcele eyengeziwe yendawo yokugcina ngokuchofoza Amapharamitha Athuthukile.

Isithombe-skrini sewizadi sokwengeza "Isizinda Sokugcina"

Ngokusekelwe emiphumeleni yewizadi, kufanele sithole indawo entsha yokugcina, futhi isikhungo sethu sedatha kufanele siye kusimo UP, noma kuqalisiwe:

Izithombe-skrini zesikhungo sedatha nezindawo zokugcina kuso:

Ukudala nokulungiselela amanethiwekhi emishini ebonakalayo

Xhumanisa nemibhalo - Umhlahlandlela Wokuphatha we-oVirt, Isahluko 6: Amanethiwekhi Anengqondo

Amanethiwekhi, noma amanethiwekhi, asebenza ekuhlanganiseni amanethiwekhi anengqondo asetshenziswa kungqalasizinda ebonakalayo ye-oVirt.

Ukuze uhlanganyele phakathi kwe-adaptha yenethiwekhi emshinini obonakalayo kanye ne-adaptha ebonakalayo kumsingathi, kusetshenziswa ukuxhumana okunengqondo njengebhuloho le-Linux.

Ukuze uqoqe futhi uhlukanise ithrafikhi phakathi kwamanethiwekhi, ama-VLAN ayalungiswa kumaswishi.

Lapho udala inethiwekhi enengqondo yemishini ebonakalayo ku-oVirt, kufanele inikezwe isihlonzi esihambisana nenombolo ye-VLAN eswitshini ukuze ama-VM akwazi ukuxhumana, ngisho noma asebenza ezindaweni ezahlukene zeqoqo.

Izilungiselelo zokuqala zama-adaptha enethiwekhi kubasingathi bokuxhuma imishini ebonakalayo bekufanele zenziwe isihloko esandulele - interface enengqondo amisiwe isibopho1, bese zonke izilungiselelo zenethiwekhi kufanele zenziwe kuphela ngephothali yokuphatha ye-oVirt.

Ngemva kokudala i-VM enenjini ephethwe, ngaphezu kokudalwa okuzenzakalelayo kwesikhungo sedatha neqoqo, inethiwekhi enengqondo nayo yadalwa ngokuzenzakalelayo ukuphatha iqoqo lethu - ovritmgmt, lapho le VM ixhunywe khona.

Uma kunesidingo, ungabuka izilungiselelo zenethiwekhi ezinengqondo ovritmgmt futhi uzilungise, kodwa kufanele uqaphele ukuthi ungalahlekelwa ukulawula ingqalasizinda ye-oVirt.

Izilungiselelo zenethiwekhi ezinengqondo ovritmgmt

Ukuze udale inethiwekhi entsha enengqondo yama-VM avamile, kuphothali yokuphatha iya ku Network >> Amanethiwekhi >> New, nakuthebhu General engeza inethiwekhi nge-ID ye-VLAN oyifunayo, bese uqoka ibhokisi eliseduze kokuthi “Inethiwekhi ye-VM", lokhu kusho ukuthi ingasetshenziselwa isabelo se-VM.

Isithombe-skrini senethiwekhi entsha enengqondo ye-VLAN32

Kuthebhu Cluster, sinamathisela le nethiwekhi kuqoqo lethu Iqoqo1.

Ngemva kwalokhu siya ku Qondanisa >> Amahostela, iya kumsingathi ngamunye ngokulandelana, kuthebhu Izixhumanisi zenethiwekhi, bese uvula iwizadi Setha amanethiwekhi osokhaya, ukubophezela kubasingathi benethiwekhi entsha enengqondo.

Isithombe-skrini sewizadi ethi "Setha amanethiwekhi osokhaya".

I-ejenti ye-oVirt izokwenza ngokuzenzakalelayo zonke izilungiselelo zenethiwekhi ezidingekayo kumsingathi - dala i-VLAN ne-BRIDGE.

Isibonelo samafayela okumisa amanethiwekhi amasha kumsingathi:

Ukudala umshini obonakalayo

Isixhumanisi samadokhumenti:
oVirt Virtual Machine Management Guide -> Isahluko 2: Ukufaka i-Linux Virtual Machines
Izinsiza Zamakhasimende e-Console

Ngemuva kokulayisha isithombe sokufaka ne-OS ku-oVirt, ungaqhubeka ngqo ekudaleni umshini obonakalayo. Mningi umsebenzi osuwenziwe, kodwa sesivele sisesigabeni sokugcina, ngenxa yalokho konke lokhu kwaqalwa - ukuthola ingqalasizinda ebekezelela amaphutha yokusingatha imishini ebonakalayo etholakala kakhulu. Futhi konke lokhu kumahhala - akukho nelilodwa isenti elichithiwe ekuthengeni noma yimaphi amalayisensi esoftware.

Ukuze udale umshini obonakalayo nge-CentOS 7, isithombe sokufaka esisuka ku-OS kufanele silandwe.

Siya ku-portal yokuphatha, iya ku Qondanisa >> Ama-Virtual Machines, futhi uqalise isilekeleli sokudala i-VM. Gcwalisa wonke amapharamitha nezinkambu bese uchofoza Kulungile. Konke kulula kakhulu uma ulandela imibhalo.

Njengesibonelo, ngizonikeza izilungiselelo eziyisisekelo nezingeziwe ze-VM etholakala kakhulu, enediski edaliwe, exhunywe kunethiwekhi, futhi iqala ngesithombe sokufaka:

Izithombe-skrini ezinezilungiselelo ze-VM ezitholakala kakhulu

Ngemva kokuqeda umsebenzi ngewizadi, yivale, qalisa i-VM entsha bese ufaka i-OS kuyo.
Ukuze wenze lokhu, iya kukhonsoli yale VM ngokusebenzisa iphothali yokuphatha:

Isithombe-skrini sezilungiselelo zephothali yokulawula yokuxhuma kukhonsoli ye-VM

Ukuze uxhume kukhonsoli ye-VM, kufanele uqale ulungiselele ikhonsoli ezindaweni zomshini obonakalayo.

Isithombe-skrini sezilungiselelo ze-VM, ithebhu ethi “Console”

Ukuxhuma kukhonsoli ye-VM ungasebenzisa, isibonelo, I-Virtual Machine Viewer.

Ukuxhuma kukhonsoli ye-VM ngqo efasiteleni lesiphequluli, izilungiselelo zokuxhuma ngekhonsoli kufanele zibe kanje:

Ngemuva kokufaka i-OS ku-VM, kuyancomeka ukuthi ufake i-oVirt i-ejenti yesivakashi:

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

Ngakho, ngenxa yezenzo zethu, i-VM edaliwe izotholakala kakhulu, i.e. uma i-cluster node esebenza kuyo yehluleka, i-oVirt izoyiqalisa kabusha ngokuzenzakalelayo endaweni yesibili. Le VM ingathuthwa futhi phakathi kwabasingathi beqoqo ukuze banakekele noma ezinye izinjongo.

isiphetho

Ngithemba ukuthi le ndatshana ikwazile ukuveza ukuthi i-oVirt iyithuluzi elijwayelekile ngokuphelele lokuphatha ingqalasizinda ebonakalayo, okungekho nzima kakhulu ukuyifaka - into esemqoka ukulandela imithetho nezidingo ezithile ezichazwe ku-athikili nakumadokhumenti.

Ngenxa yomthamo omkhulu we-athikili, akukwazanga ukufaka izinto eziningi kuyo, njengokwenza isinyathelo ngesinyathelo kwabathakathi abahlukahlukene nazo zonke izincazelo ezinemininingwane nezithombe-skrini, iziphetho ezinde zeminye imiyalo, njll. Eqinisweni, lokhu kungadinga ukubhala incwadi yonke, engenzi mqondo kangako ngenxa yezinguqulo ezintsha zesofthiwe ezihlala zivela ngokuqanjwa nezinguquko. Okubaluleke kakhulu ukuqonda umgomo wokuthi konke kusebenza kanjani ndawonye, futhi ukuthola i-algorithm evamile yokudala inkundla yokubekezelela amaphutha yokuphatha imishini ebonakalayo.

Nakuba sidale ingqalasizinda ebonakalayo, manje sidinga ukuyifundisa ukusebenzisana kokubili phakathi kwezinto zayo ezingazodwana: abasingathi, imishini ebonakalayo, amanethiwekhi angaphakathi, kanye nomhlaba wangaphandle.

Le nqubo ingomunye wemisebenzi esemqoka yesistimu noma yomqondisi wenethiwekhi, okuzoxoxwa ngayo esihlokweni esilandelayo - mayelana nokusetshenziswa kwama-VyOS ama-virtual routers engqalasizinda ebekezelela amaphutha yebhizinisi lethu (njengoba ubuqagele, azosebenza njenge-virtual. imishini kuqoqo lethu le-oVirt).
