Kusikwa kweiyo inokanganisa-inoshivirira IT zvivakwa. Chikamu 2. Kuisa nekugadzirisa oVirt 4.3 cluster

Chinyorwa ichi kuenderera mberi kwechakapfuura - “Kusikwa kweiyo inokanganisa-inoshivirira IT zvivakwa. Chikamu 1 - kugadzirira kuendesa oVirt 4.3 sumbu".

Ichavhara maitiro ekuisirwa kwekutanga uye kumisikidzwa kweiyo oVirt 4.3 cluster yekutambira inowanika chaiwo michina, tichifunga nezvekuti matanho ese ekutanga ekugadzirira zvivakwa akatopera kare.

Chikamu chekutanga

Chinangwa chikuru chechinyorwa ndechekupa nhanho-ne-nhanho mirairo senge "Next -> Ehe -> pedza"maitiro ekuratidza mamwe maficha paunenge uchiisa uye nekuigadzirisa. Iyo nzira yekuisa cluster yako inogona kusagara ichienderana neinotsanangurwa mairi, nekuda kwehunhu hwezvivakwa uye zvakatipoteredza, asi misimboti yese ichafanana.

Kubva pane subjective maonero, oVirt 4.3 kushanda kwayo kwakafanana neVMware vSphere vhezheni 5.x, asi chokwadi ine magadzirirwo ayo uye maitiro ekushanda.

Kune avo vanofarira, misiyano yese pakati peRHEV (aka oVirt) neVMware vSphere inogona kuwanikwa paInternet, semuenzaniso. pano, asi ndicharamba ndichicherechedza dzimwe nguva kusiyana kwavo kana kufanana kwavo sezvo nyaya inoenderera mberi.

Takaparadzana, ndinoda kuenzanisa zvishoma basa nemanetiweki emakina chaiwo. oVirt inoshandisa musimboti wakafanana wetiweki manejimendi emakina chaiwo (pano anonzi maVM), seVMware vSphere:

• uchishandisa yakajairika Linux bhiriji (muVMware - Standard vSwitch), kumhanya pane virtualization mauto;
• uchishandisa Vhura vSwitch (OVS) (muVMware - Yakagoverwa vSwitch) ishanduko yakagoverwa inoumbwa nezvikamu zviviri zvikuru: sevha yepakati yeOVN uye maOVN controllers pane anotungamirirwa.

Izvo zvinofanirwa kucherechedzwa kuti nekuda kwekureruka kwekuita, chinyorwa chinotsanangura kumisikidza network muoVirt yeVM uchishandisa yakajairwa Linux bhiriji, inova ndiyo yakajairika sarudzo kana uchishandisa KVM hypervisor.

Panyaya iyi, kune akati wandei mitemo yekushanda netiweki musumbu, izvo zviri nani kuti zvisatyorwe:

• Ese masethingi etiweki pane anotambira usati waawedzera kuOVirt anofanira kunge akafanana, kunze kweIP kero.
• Kana muenzi achinge atorwa achitongwa neoVirt, hazvikurudzirwe zvakanyanya kuti uchinje chero chinhu pamaoko mumasetirwo etiweki pasina chivimbo chakazara muzviito zvako, sezvo mumiriri weoVirt anongozvidzosera kune zvakapfuura mushure mekutangazve muenzi kana. mumiririri.
• Kuwedzera network nyowani yeVM, pamwe nekushanda nayo, zvinofanirwa kungoitwa kubva kuoVirt management console.

Imwe kukosha kwakakosha - yenzvimbo yakaoma kwazvo (inotarisisa kurasikirwa kwemari), zvinoramba zvichikurudzirwa kushandisa rubatsiro rwakabhadharwa uye kushandiswa. Red Hat Virtualization 4.3. Munguva yekushanda kweboka reoVirt, dzimwe nyaya dzinogona kumuka dzinofanirwa kugashira rubatsiro rwakakodzera nekukurumidza, pane kutarisana nadzo iwe pachako.

Pakupedzisira, yakakurudzirwa Usati watumira oVirt cluster, zvizivisei zvinyorwa zvepamutemo, kuitira kuti tizive zvishoma nezvepfungwa dzinokosha uye tsananguro, kana zvisina kudaro zvichange zvakaoma kuverenga chikamu chakasara.

Yakakosha pakunzwisisa chinyorwa uye misimboti yekushanda kweiyo oVirt cluster aya magwaro ekutungamira:

• oVirt Installation Guide
• oVirt Self-Hosted Engine Guide
• oVirt Administration Guide
  

Vhoriyamu iripo haina kukura zvakanyanya, muawa kana maviri iwe unogona kunyatso hunyanzvi misimboti, asi kune avo vanoda ruzivo, zvinokurudzirwa kuverenga. Chigadzirwa Zvinyorwa zveRed Hat Virtualization 4.3 - RHEV uye oVirt zvinhu zvakafanana.

Saka, kana ese ekutanga marongero pane anotambira, switch uye ekuchengetedza masisitimu apedzwa, isu tinopfuurira takananga kuendeswa kweoVirt.

Chikamu 2. Kuisa nekugadzirisa oVirt 4.3 cluster

Kuti zvive nyore kutungamira, ini ndichanyora zvikamu zvikuru muchinyorwa chino, izvo zvinofanirwa kupedzwa chimwe nechimwe:

1. Kuisa iyo oVirt manejimendi server
2. Kugadzirwa kwenzvimbo itsva yedata
3. Kugadzira sumbu idzva
4. Kuisa mamwe mauto munzvimbo yeSelf-Hosted
5. Kugadzira nzvimbo yekuchengetera kana Storage Domains
6. Kugadzira uye kugadzirisa network kune chaiwo michina
7. Kugadzira mufananidzo wekugadza wekutumira muchina chaiwo
8. Gadzira muchina chaiwo

Kuisa iyo oVirt manejimendi server

oVirt maneja server - ichi ndicho chinhu chakanyanya kukosha mune oVirt zvivakwa, muchimiro chemushini chaiwo, muenzi, kana mudziyo unobata iyo yose oVirt zvivakwa.

Yayo yepedyo analogues kubva munyika ye virtualization ndeiyi:

• VMware vSphere - vCenter Server
• Microsoft Hyper-V - System Center Virtual Machine Maneja (VMM).

Kuisa oVirt management server, isu tine sarudzo mbiri:

Sarudzo 1
Kuendesa sevha muchimiro chehunyanzvi VM kana muenzi.

Iyi sarudzo inoshanda chaizvo, asi chero iyo VM yakadaro ichishanda yakazvimiririra kubva kune sumbu, i.e. haisi kumhanya pane chero cluster host seyakajairika muchina unomhanya KVM.

Sei iyo VM yakadaro isingagone kuiswa pamapoka makuru?

Pakutanga kwemaitiro ekuisa iyo oVirt manejimendi server, isu tine dambudziko - isu tinofanirwa kuisa manejimendi VM, asi kutaura zvazviri hapana cluster pachayo, uye saka chii chatingauye nacho panhunzi? Ndizvozvo - isa KVM pane ramangwana cluster node, wobva wagadzira muchina chaiwo pairi, semuenzaniso, neCentOS OS uye shandisa oVirt injini mairi. Izvi zvinowanzoitwa nekuda kwezvikonzero zvekutonga kwakazara pamusoro peVM yakadaro, asi ichi ivavariro isiriyo, nekuti mune iyi kesi, mune ramangwana kuchava ne100% matambudziko neiyo control VM:

• haigone kutamirwa muoVirt console pakati pemahosi (node) yesumbu;
• paunenge uchitama uchishandisa KVM kuburikidza virsh migrate, VM iyi haizowanikwe kune manejimendi kubva kuoVirt console.
• cluster host haigone kuratidzwa mukati Maitiro ekugadzirisa (maitirwo ekugadzirisa), kana iwe ukatama iyi VM kubva kune imwe nzvimbo kuenda kune yekugamuchira uchishandisa virsh migrate.

Saka ita zvese zvinoenderana nemirairo - shandisa ingave yakaparadzana mugadziri weoVirt manejimendi server, kana yakazvimirira VM inomhanya pairi, kana zvirinani zvakadaro, ita sezvakanyorwa mune yechipiri sarudzo.

Sarudzo 2
Kuisa oVirt Engine Appliance pane cluster host inotungamirirwa nayo.

Iyi ndiyo sarudzo inozotariswa zvakare seyakanyanya kunaka uye yakakodzera mune yedu.
Zvinodiwa zveVM yakadai zvinotsanangurwa pazasi; Ini ndinongowedzera kuti zvinokurudzirwa kuve neanokwana maviri mauto mune zvivakwa umo iyo control VM inogona kumhanyirwa kuitira kuti irege kukanganisa. Pano ndinoda kuwedzera kuti, sezvandakatonyora mumashoko munyaya yapfuura, handina kumbokwanisa kuwana splitbrain pane oVirt cluster yemauto maviri, nekugona kumhanyisa-injini VMs pavari.

Kuisa oVirt Engine Appliance pane yekutanga host yesumbu

Batanidza kune zviri pamutemo zvinyorwa - oVirt Self-Hosted Engine Guide, chitsauko "Kutumira Injini Yekuzvimiririra Uchishandisa Mutsetse Wekuraira»

Gwaro racho rinotsanangura zvinodikanwa zvinofanirwa kuzadzikiswa musati maisa hosted-injini VM, uye zvakare inotsanangura zvakadzama maitiro ekuisirwa pachayo, saka hapana chikonzero chekuchidzokorora neshoko, saka isu tichatarisa pane mamwe akakosha ruzivo.

• Usati watanga zviito zvese, ita shuwa yekugonesa virtualization rutsigiro mune BIOS marongero pane iyo host.
• Isa iyo pasuru yeyakagadzirirwa-injini yekuisa pane iyo host:

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

• Isu tinotanga maitiro ekuisa oVirt Yakagashirwa Injini pane iyo inomiririra iri pachiratidziri (iwe unogona kubuda nayo kuburikidza neCtrl-A + D, kuvhara neCtrl-D):

Zvose izvi zviito zvichakurukurwa mberi, zvimwe mumasero makuru, mamwe mune zvakadzama uye nemanuances.
Asi chekutanga ndinoda kukurudzira kuverenga iyi yekuwedzera, iyo ingangove inobatsira kune vakawanda.

Kuwedzera

1) Muchidimbu, kana paine chinodiwa chakadaro, saka hapana chinokutadzisa kuisa iyo KVM hypervisor pane cluster node pamberi uchishandisa mapakeji. libvirt и kemu-kvm (kana qemu-kvm-ev) yeshanduro yaunoda, kunyangwe kana uchitumira oVirt cluster node, inogona kuita izvi pachayo.

Asi kana libvirt и kemu-kvm Kana usati waisa iyo yazvino vhezheni, unogona kugashira chikanganiso chinotevera paunenge uchitumira injini inobatwa:

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

Avo. anofanira kuva nazvo update version libvirt nekudzivirirwa kubva MDS, inotsigira mutemo uyu:

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

Isa libvirt v.4.5.0-10.el7_6.12, ine md-yakajeka rutsigiro:

Storage Domain, kana nzvimbo yekuchengetera, inzvimbo yepakati yekuchengetera madhisiki emuchina wemadhisiki, mifananidzo yekuisa, matemplate, uye snapshots.

Nzvimbo dzekuchengetera dzinogona kubatanidzwa kune data data uchishandisa akasiyana maprotocol, cluster uye network faira masisitimu.

oVirt ine marudzi matatu enzvimbo yekuchengetera:

• Dhata Domain - kuchengetedza data rese rakabatana nemashini chaiwo (madhisiki, matemplate). Data Domain haigone kugovaniswa pakati penzvimbo dzakasiyana dze data.
• ISO Domain (rudzi rwakasakara rwenzvimbo yekuchengetera) - yekuchengetedza OS yekuisa mifananidzo. ISO Domain inogona kugoverwa pakati penzvimbo dzakasiyana dze data.
• Export Domain (yakareruka rudzi rwenzvimbo yekuchengetedza) - yekuchengetedza kwechinguvana kwemifananidzo yakafambiswa pakati pe data data.

Mune yedu chaiyo, nzvimbo yekuchengetera ine iyo Data Domain mhando inoshandisa Fiber Channel Protocol (FCP) kubatana neLUNs pane yekuchengetedza system.

Kubva pakuona kweOVirt, kana uchishandisa masisitimu ekuchengetedza (FC kana iSCSI), yega yega dhisiki, snapshot kana template idhisiki inonzwisisika.
