Ka hana ʻana i kahi ʻōnaehana IT ʻae ʻole i ka hewa. Mahele 2. Hoʻokomo a hoʻonohonoho i ka hui oVirt 4.3

He hoʻomau kēia ʻatikala o ka mua - "Ka hana ʻana i nā ʻōnaehana IT ʻae ʻole i ka hewa. Mahele 1 - Hoʻomākaukau e hoʻolaha i kahi hui oVirt 4.3".

E uhi ia i ke kaʻina hana o ka hoʻonohonoho kumu a me ka hoʻonohonoho ʻana o kahi pūʻulu oVirt 4.3 no ka hoʻokipa ʻana i nā mīkini virtual i loaʻa loa, me ka noʻonoʻo ʻana ua pau nā hana mua a pau no ka hoʻomākaukau ʻana i ka ʻoihana.

Hoʻomau

ʻO ke kumu nui o ka ʻatikala ka hāʻawi ʻana i nā ʻōlelo aʻoaʻo i kēlā me kēia pae e like me "Aʻe -> ʻAe -> a pau"pehea e hōʻike ai i kekahi mau hiʻohiʻona i ka wā e hoʻokomo ai a hoʻonohonoho iā ia. ʻAʻole like paha ke kaʻina hana no ka lawe ʻana i kāu puʻupuʻu me ka mea i wehewehe ʻia i loko, ma muli o nā hiʻohiʻona o ka ʻōnaehana a me ke kaiapuni, akā e like nō nā loina maʻamau.

Mai ka manaʻo kumuhana, oVirt 4.3 ua like kona hana me VMware vSphere version 5.x, akā, me kona hoʻonohonoho ponoʻī a me nā hiʻohiʻona hana.

No ka poʻe hoihoi, hiki ke loaʻa nā ʻokoʻa āpau ma waena o RHEV (aka oVirt) a me VMware vSphere ma ka Pūnaewele, no ka laʻana. maanei, akā, e hoʻomanaʻo mau ana au i kekahi o kā lākou mau ʻokoʻa a i ʻole like kekahi me kekahi i ka holomua ʻana o ka ʻatikala.

Ma kahi kaʻawale, makemake wau e hoʻohālikelike i ka hana me nā pūnaewele no nā mīkini virtual. Hoʻokomo ʻo oVirt i kahi loina like o ka hoʻokele pūnaewele no nā mīkini virtual (i kapa ʻia ma hope nei he VM), e like me VMware vSphere:

• e hoʻohana ana i kahi alahaka Linux maʻamau (ma VMware - vSwitch maʻamau), e holo ana ma nā pūʻali virtualization;
• e hoʻohana ana i ka Open vSwitch (OVS) (ma VMware - Māhele ʻia vSwitch) he hoʻololi virtual i māhele ʻia me ʻelua mau mea nui: kahi kikowaena OVN kikowaena a me nā mea hoʻokele OVN ma nā pūʻali hoʻokele.

Pono e hoʻomaopopoʻia ma muli o ka maʻalahi o ka hoʻokōʻana, e wehewehe kaʻatikala i ka hoʻonohonohoʻana i nā pūnaewele ma oVirt no kahi VM e hoʻohana ana i kahi alahaka Linux maʻamau,ʻo ia ke koho maʻamau i ka hoʻohanaʻana i ka hypervisor KVM.

В связи с этим имеется несколько базовых правил по работе с сетью в кластере, которые лучше не нарушать:

• ʻO nā hoʻonohonoho pūnaewele āpau ma nā pūʻali ma mua o ka hoʻohui ʻana iā lākou i oVirt pono e like, koe wale nō nā helu IP.
• I ka manawa i lawe ʻia ai kahi mea hoʻokipa ma lalo o ka mana o oVirt, ʻaʻole makemake nui ʻia e hoʻololi i kekahi mea me ka lima ma nā hoʻonohonoho pūnaewele ma luna o ia mea, me ka hilinaʻi ʻole i kāu mau hana, no ka mea, e ʻōwili wale ka luna oVirt iā lākou i nā mea ma mua ma hope o ka hoʻomaka ʻana i ka. mea hoʻokipa a luna paha.
• ʻO ka hoʻohui ʻana i kahi pūnaewele hou no kahi VM, a me ka hana pū ʻana me ia, pono e hana ʻia mai ka console hoʻokele oVirt.

ʻO kekahi palapala nui - no kahi kaiapuni koʻikoʻi (pilikia loa i nā poho kālā), e ʻōlelo ʻia e hoʻohana i ke kākoʻo uku a hoʻohana. ʻO ka Red Hat Virtualization 4.3. I ka wā o ka hana ʻana o ka pūʻulu oVirt, hiki ke kū mai kekahi mau pilikia e pono ai e loaʻa ke kōkua kūpono i ka wā hiki, ma mua o ka hoʻoponopono ʻana iā ʻoe iho.

Ma ka hopena, ua konoia Ma mua o ka kau ʻana i kahi pūʻulu oVirt, e hoʻomaʻamaʻa iā ʻoe iho palapala kūhelu, i mea e ʻike ai i nā manaʻo kumu a me nā wehewehe, i ʻole e paʻakikī iki ke heluhelu ʻana i ke koena o ka ʻatikala.

ʻO ke kumu o ka hoʻomaopopo ʻana i ka ʻatikala a me nā loina o ka hana o ka hui oVirt kēia mau palapala alakaʻi:

• ʻO ke alakaʻi hoʻokomo oVirt
• oVirt Ke alakaʻi alakaʻi ʻenekini
• oVirt alakai alakai
  

ʻAʻole nui ka leo ma laila, i loko o hoʻokahi hola a ʻelua paha hiki iā ʻoe ke haku i nā kumu kumu, akā no ka poʻe makemake i nā kikoʻī, ʻōlelo ʻia e heluhelu. Palapala Huahana no ka Red Hat Virtualization 4.3 — ʻO RHEV a me oVirt ka mea like.

No laila, inā ua hoʻopau ʻia nā hoʻonohonoho kumu āpau i nā hosts, nā hoʻololi a me nā ʻōnaehana mālama, hoʻomau pololei mākou i ka waiho ʻana o oVirt.

Mahele 2. Hoʻokomo a hoʻonohonoho i ka hui oVirt 4.3

No ka maʻalahi o ka hoʻonohonoho ʻana, e papa inoa wau i nā ʻāpana nui o kēia ʻatikala, pono e hoʻopau ʻia i kēlā me kēia:

1. Ke hoʻokomo nei i ke kikowaena hoʻokele oVirt
2. Ka hana ʻana i kahi kikowaena ʻikepili hou
3. Ke hana ʻana i kahi hui hou
4. Ke hoʻouka nei i nā pūʻali hou i loko o kahi kaiapuni Self-Hosted
5. Ke hana ʻana i kahi waiho ʻana a i ʻole nā ​​kahua mālama
6. Ka hana ʻana a me ka hoʻonohonoho ʻana i nā pūnaewele no nā mīkini virtual
7. Ke hana ʻana i kahi kiʻi hoʻonohonoho no ka hoʻokau ʻana i kahi mīkini virtual
8. E hana i ka mīkini virtual

Ke hoʻokomo nei i ke kikowaena hoʻokele oVirt

oVirt hoʻokele kikowaena - ʻo kēia ka mea koʻikoʻi loa i ka ʻōnaehana oVirt, ma ke ʻano o kahi mīkini virtual, host, a i ʻole mea uila e hoʻokele i ka ʻōnaehana oVirt holoʻokoʻa.

ʻO kāna mau analogues kokoke mai ka honua o virtualization:

• VMware vSphere - vCenter Server
• Microsoft Hyper-V - Pūnaehana Pūnaewele Virtual Machine Manager (VMM).

No ka hoʻouka ʻana i ka server hoʻokele oVirt, ʻelua mau koho:

Kō koho 1
Ke hoʻolālā nei i kahi kikowaena ma ke ʻano o kahi VM kūikawā a i ʻole host.

Hana maikaʻi kēia koho, akā inā e hana kaʻawale kēlā VM mai ka pūpū, ʻo ia hoʻi. ʻaʻole ia e holo ana ma luna o kekahi pūʻulu pūʻulu ma ke ʻano he mīkini virtual maʻamau e holo ana iā KVM.

No ke aha e hiki ʻole ai ke kau ʻia kahi VM ma luna o nā pūʻali pūʻulu?

I ka hoʻomaka ʻana o ke kaʻina hana o ka hoʻokele oVirt server, loaʻa iā mākou kahi pilikia - pono mākou e hoʻokomo i kahi VM hoʻokele, akā ʻoiaʻiʻo, ʻaʻohe puʻupuʻu ponoʻī, a no laila he aha kā mākou e hele mai ai me ka lele? Pololei - e hoʻokomo iā KVM ma kahi puʻupuʻu puʻupuʻu e hiki mai ana, a laila hana i kahi mīkini virtual ma luna, no ka laʻana, me CentOS OS a kau i ka mīkini oVirt i loko. Hiki ke hana maʻamau kēia no nā kumu o ka mana piha ma luna o kēlā VM, akā he manaʻo kuhihewa kēia, no ka mea ma kēia hihia, i ka wā e hiki mai ana he 100% nā pilikia me kēlā mana VM:

• ʻaʻole hiki ke neʻe ʻia ma ka console oVirt ma waena o nā pūʻali (nodes) o ka hui;
• i ka neʻe ʻana me ka hoʻohana ʻana iā KVM ma o virsh migrate, ʻaʻole e loaʻa kēia VM no ka hoʻokele ʻana mai ka console oVirt.
• ʻAʻole hiki ke hōʻike ʻia nā pūʻali pūʻulu Mālama mālama (mode mālama), inā ʻoe e neʻe i kēia VM mai ka host i ka hoʻohana ʻana virsh migrate.

No laila e hana i nā mea a pau e like me nā lula - e hoʻohana i kahi hoʻokipa ʻokoʻa no ka server hoʻokele oVirt, a i ʻole kahi VM kūʻokoʻa e holo ana ma luna o ia, a ʻoi aku ka maikaʻi, e hana e like me ka mea i kākau ʻia ma ka koho lua.

Kō koho 2
Ke hoʻokomo nei i ka oVirt Engine Appliance ma kahi pūʻali pūʻali i mālama ʻia e ia.

ʻO kēia koho ka mea e noʻonoʻo ʻia ʻoi aku ka pololei a kūpono i kā mākou hihia.
ʻO nā koi no ia VM e wehewehe ʻia ma lalo nei; E hoʻohui wale au i ka manaʻo ʻia e loaʻa i ʻelua mau pūʻali koa i loko o ka ʻōnaehana kahi e holo ai ka mana VM i mea e hoʻomanawanui ai. Eia wau makemake e hoʻohui i kēlā, e like me kaʻu i kākau ai ma nā ʻōlelo ma ka ʻatikala mua, ʻaʻole hiki iaʻu ke loaʻa ʻauʻau hoʻokaʻawale ma kahi hui oVirt o ʻelua mau pūʻali, me ka hiki ke holo i nā VM hosted-engine ma luna o lākou.

Ke kau nei i ka oVirt Engine Appliance ma ka pūʻali mua o ka hui

loulou i nā palapala kūhelu - oVirt Ke alakaʻi alakaʻi ʻenekini, mokuna "Ke hoʻohana nei i ka ʻenekini hoʻokele ponoʻī me ka hoʻohana ʻana i ka laina kauoha»

Hōʻike ka palapala i nā koi pono e hoʻokō ʻia ma mua o ka lawe ʻana i kahi VM hosted-engine, a wehewehe kikoʻī hoʻi i ke kaʻina hana hoʻonohonoho ponoʻī, no laila ʻaʻohe wahi liʻiliʻi o ka haʻi ʻana i ka verbatim, no laila e nānā mākou i kekahi mau kikoʻī koʻikoʻi.

• Ma mua o ka hoʻomaka ʻana i nā hana āpau, e hōʻoia e hiki i ke kākoʻo virtualization i nā hoʻonohonoho BIOS ma ka host.
• E hoʻouka i ka pūʻolo no ka mea hoʻonoho ʻenekini hoʻokipa ma ka host:

yum -y install http://resources.ovirt.org/pub/yum-repo/ovirt-release43.rpm

• Hoʻomaka mākou i ke kaʻina hana no ka lawe ʻana i ka oVirt Hosted Engine i ka pale ma ka host (hiki iā ʻoe ke haʻalele iā ia ma Ctrl-A + D, kokoke ma Ctrl-D):

Inā makemake ʻoe, hiki iā ʻoe ke holo i ka hoʻonohonoho ʻana me kahi faila pane i hoʻomākaukau mua ʻia:

• Ke kau nei i ka hosted-engine, kuhikuhi mākou i nā ʻāpana pono a pau:

- 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. 

• No ka hoʻouka ʻana i kahi VM i loaʻa loa me kahi mīkini hoʻokipa, ua hana mua mākou i kahi LUN kūikawā ma ka ʻōnaehana mālama, helu 4 a me 150 GB ka nui, a laila hōʻike ʻia i nā pūʻali cluster - ʻike. ʻatikala mua.

Ma mua ua nānā pū mākou i kona ʻike ʻia ma nā mea hoʻokipa:

5. hoʻohui a hoʻonohonoho i nā pūnaewele no nā mīkini virtual
6. hoʻohui a hoʻokele i nā mīkini virtual, nā kiʻi hoʻonohonoho, nā ʻōkuhi VM

E kūkākūkā hou ʻia kēia mau hana a pau, ʻo kekahi i loko o nā cell nui, ʻo nā mea ʻē aʻe i nā kikoʻī a me nā nuances.
Akā ʻo ka mea mua, makemake wau e heluhelu i kēia add-on, he mea pono paha ia i nā mea he nui.

Hoʻohui

1) Ma ke kumu, inā he pono ia, a laila ʻaʻohe mea e pale iā ʻoe mai ka hoʻokomo ʻana i ka hypervisor KVM ma nā nodes cluster ma mua o ka hoʻohana ʻana i nā pūʻulu. ponoʻewa и qemu-kvm (ai ole qemu-kvm-ev) o ka mana i makemake ʻia, ʻoiai ke kau ʻana i kahi oVirt cluster node, hiki iā ia ke hana iā ia iho.

Akā, inā ponoʻewa и qemu-kvm Inā ʻaʻole ʻoe i hoʻokomo i ka mana hou loa, e loaʻa paha iā ʻoe kēia hewa i ka wā e kau ana i kahi ʻenekini hoʻokipa:

ʻO kēlā mau mea. pono e loaa mana hou ponoʻewa me ka palekana mai MDS, e kākoʻo ana i kēia kulekele:

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

E hoʻouka i ka libvirt v.4.5.0-10.el7_6.12, me ke kākoʻo md-clear:

Ma hope o kēia, hiki iā ʻoe ke hoʻomau i ka hoʻokomo ʻana i ka mīkini hoʻokipa.

2) Ma oVirt 4.3, ke alo a me ka hoʻohana ʻana i kahi pā ahi ke ahi he koi koi.

Inā i ka wā o ka hoʻolālā ʻana o kahi VM no ka hosted-engine e loaʻa iā mākou ka hewa aʻe:

Ma hope aku, i ka wā e hoʻokomo ai i ka luna ovirt ma kahi hoʻokipa hou no ka pūʻulu, e hoʻonohonoho ia i nā awa i koi ʻia ma ke ahi kopeʻokoʻa.

3) Hoʻomaka hou i kahi mea hoʻokipa me kahi VM e holo ana ma luna me kahi mīkini hoʻokipa.

O ka maʻamau, loulou 1 и loulou 2 i nā palapala hoʻomalu.

Hana ʻia ka hoʻokele a pau o ka mīkini hoʻokipa VM me ka hoʻohana ʻana i ke kauoha ʻenekini hoʻokipa ma luna o ka mea hoʻokipa kahi e holo ai, ma kahi o Virsh pono mākou e poina, a me ka mea hiki iā ʻoe ke hoʻopili i kēia VM ma o SSH a holo i ke kauoha "e hoʻopio".

Ma kā mākou hihia kūikawā, hoʻohana kahi wahi mālama me ke ʻano Domain Domain Fiber Channel Protocol (FCP) e hoʻopili i nā LUN ma ka ʻōnaehana mālama.

Ma muli o ka nui o ka ʻatikala, ʻaʻole hiki ke hoʻokomo i nā mea he nui i loko, e like me ka hoʻokō ʻana i kēlā me kēia pae o nā wizards me nā wehewehe kikoʻī āpau a me nā screenshots, nā hopena lōʻihi o kekahi mau kauoha, etc. ʻO ka ʻoiaʻiʻo, pono kēia e kākau i kahi puke holoʻokoʻa, ʻaʻole i manaʻo nui ʻia ma muli o nā mana hou o nā polokalamu e ʻike mau ʻia me nā mea hou a me nā loli. ʻO ka mea nui loa, ʻo ia ka hoʻomaopopo ʻana i ke kumu o ka hana like ʻana o ia mau mea a pau, a loaʻa i kahi algorithm maʻamau no ka hoʻokumu ʻana i kahi kahua hoʻomanawanui hewa no ka mālama ʻana i nā mīkini virtual.

ʻOiai ua hana mākou i kahi ʻōnaehana virtual, pono mākou i kēia manawa e aʻo iā ia e launa pū ma waena o kāna mau mea ponoʻī: hosts, virtual machines, internal networks, and with the outside world.

ʻO kēia kaʻina hana kekahi o nā hana nui o kahi ʻōnaehana a i ʻole ka luna hoʻomalu pūnaewele, e uhi ʻia ma ka ʻatikala aʻe - e pili ana i ka hoʻohana ʻana i nā mea hoʻokele virtual VyOS i ka ʻōnaehana hoʻomanawanui hewa o kā mākou ʻoihana (e like me kāu i manaʻo ai, e hana lākou ma ke ʻano he virtual. nā mīkini ma kā mākou hui oVirt).
