I-CentOS 7 Hypervisor II kunye neenethiwekhi zokugqibela ze-SMB

Isalathiso ngokubanzi sothotho: Iinethiwekhi zekhompyuter zee-SMEs: Intshayelelo

Molweni zihlobo!

Uyakwazo oko? Nawaphi na amanye amabinzana okuqala kwenqaku, njengoko ndizamile kwizithuba zangaphambili, akubonakali kufanelekile, yiyo loo nto ndibuyela kumbuliso wam oqhelekileyo, ngokuqinisekileyo kwaye wandisiwe, kubandakanya aBafundi esaziyo ukuba nabo bangabahlali. .

Namhlanje lusuku lokuqala lonyaka ka-2017 kwaye sifuna ukongeza kubo bonke abafundi bethu, eyona mibulelo inyanisekileyo kuNyaka oMtsha osanda kuqala:

• Siyavuyisana noNyaka oMtsha onwabile kubo bonke!.

Kwaye njengePrezenti yokuqala konyaka, sikuzisa inxenye yesi-2- kunye neyokugqibela- yendlela esinokuthi ngayo Lawula kude i-hypervisor kwi-CentOS 7 yenziwe kwinqaku elandulelayo kuthotho Iinethiwekhi zeSME, njengoko siza kuyibiza apha ngokufutshane.

Asiyi kunika amakhonkco amaninzi phakathi kwemigca, kuba sicinga ukuba izithuba zangaphambili kuthotho «Iinethiwekhi zekhompyuter zee-SMEs«, Kwaye nokuba sele beqhelene namagama, izifinyezo kunye neenkcazo. Ngawaphi loo maphepha?

• Iinethiwekhi zekhompyuter zee-SMEs: Intshayelelo
• Ukufakwa kwendawo yokusebenza
• Iidesika ezi-6 zeDebian
• Ukusebenza ngokunyanisekileyo kwiDebian: Intshayelelo

Sikwacebisa ukuba sifunde eli nqaku lilandelayo, njengoko inika inxenye yokukhetha ulwabiwo lweLinux esizenzele olu luhlu lukhankanyiweyo lwezithuba:

• Ukuhanjiswa ngokuhanjiswa kwexesha kweLinux

Ukulawula kude i-centos7 hypervisor

Siza kuphela ukusebenzisa ikhonsoli kunye nemiyalelo umtshana y ukufaka-ukufaka. Ukwenza ubomi bube lula kuthi kuba ASIKHO i-DNS okwangoku:

buzz @ sysadmin: ~ $ nano / njl / imikhosi
127.0.0.1 localhost 10.10.10.10 sysadmin.desdelinux.fan sysadmin 10.10.10.4 centos7.desdelinux.fan centos7 # Le migca ilandelayo iyanqweneleka kwi IPv6 iinginginya ezikwaziyo ::1 localhost ip6-localhost ip6-loopback ff02::1 ip6-allnodes ff02::2 ip6-allrouters # ------------ -------------------

Sicela umyalelo umtshana ukusuka kwindawo yethu yokusebenza:

buzz @ sysadmin: ~ $ sudo virsh
[Sudo] iphasiwedi ye-buzz: Wamkelekile kwi-virsh, i-virtualization interactive terminal. Uhlobo: 'uncedo' ngoncedo lwemiyalelo 'yokuyeka' ukuyeka

Ukuthintela ukwenza imiyalelo kwi-hypervisor engeyiyo!

i-virsh # uri
qemu: / inkqubo
# Sikwi hypervisor yendawo okanye "sysadmin".

Sidibanisa ne-hypervisor ekude

i-virsh # qhagamshela qemu + ssh: // ingcambu @ centos7 / inkqubo
Ubunyani be-centos7 yomamkeli (10.10.10.4) 'abunakuqinisekiswa. Iminwe ephambili ye-ECDSA ngu-71: b9: d9: f7: 30: 58: 07: 7f: a9: 78: 53: 21: 54: 67: 26: 4f. Uqinisekile ukuba ufuna ukuqhubeka nokunxibelelana (ewe / hayi)? ewe ingcambu @ centos7 iphasiwedi:

Ukuba inyathelo elidlulileyo libuyisa impazamo yokungqinisisa, kuya kufuneka ucime ifayile /root/, kwaye uzame kwakhona.

i-virsh # uri

# Sele sixhunyiwe kwi-hypervisor ekude

Ukugcinwa kwi-hypervisor ekude

Senza indawo yokugcina yokugcina enkulu kwi-centos7

buzz @ sysadmin: ~ $ ssh (Imeyile ikhuselwe) @ centos7
ingcambu @ centos7 iphasiwedi: 

[(Imeyile ikhuselwe) ~] # mkdir / ikhaya / vms

Ukuphuma koNxibelelwano ukuya kwi-10.10.10.4 kuvaliwe.

Sibuyele kwi-sysadmin nakwi-virsh

buzz @ sysadmin: ~ $ sudo virsh
Wamkelekile kwi-virsh, i-virtualization interactive terminal. Uhlobo: 'uncedo' ngoncedo lwemiyalelo 'yokuyeka' ukuyeka

Asifuni ukuqala ngokuzenzekelayo kwediphozithi "okungagqibekanga"

i-virsh # i-pool-autostart engagqibekanga-inokukhubazeka
Okungagqibekanga kwephuli akubonakaliswanga njengokuqalisa kwakhona

Sichaza i-emele yokugcina entsha kwindawo esandula ukwenziwa / ikhaya / i-vms

i-virsh # echibini-chaza-njengegama-le-centos7-vms -type dir -target / ikhaya / vms -ifomathi yezixhobo ze-xfs

Senza umfanekiso womatshini oqinisekileyo «wordpress»

Qaphela: umfanekiso we-ISO ovulekileyoSUSE besikhuphele ngaphambili kwindawo yokugcina centos7-vms. Kungenxa yoko le nto idweliswe apha ngezantsi. Ngokucacileyo sifuna ukufaka i-WordPress kusasazo lwe-OpenSuSE.

i-virsh # yokuhlaziya i-pool centos7-vms
Iphuli yeepesenti ze-7-vms zihlaziyiwe

uluhlu lwe-virsh # vol-uluhlu lwe-centos7-vms
 Indlela yegama ---------------------------------------------------- ------------------------------ vulaSUSE-13.2-DVD-x86_64.iso /home/vms/openSUSE-13.2-DVD- x86_64.iso

i-virsh # vol-create-as -pool centos7-vms -name wordpress.raw - amandla e-40G
IVolterpress.raw yenziwe

Iinethiwekhi eziqinisekileyo

Sisusa i-DHCP kwinethiwekhi emiselweyo

uluhlu lwe-virsh # net-yonke
 Igama I-State Autostart eqhubekayo -------------------------------------------------- ------------ sisebenza ewe ewe

i-virsh # net-info engagqibekanga
Igama: i-UUID emiselweyo: 2a2ef469-3008-45f9-a165-ab1fb8f6277b Iyasebenza: ewe iyaqhubeka: ewe Autostart: ewe Bridge: virbr0

Uthungelwano "olungagqibekanga" lufumaneka ngolu hlobo

virsh # net-edit-default
emiselweyo 18ce4bbb-fddb-4300-9f13-65b4d999690c 

Kwaye siza kuyishiya ngoluhlobo

emiselweyo 2a2ef469-3008-45f9-a165-ab1fb8f6277b 

Sisebenzisa utshintsho

virsh # net-ukutshabalalisa okungagqibekanga
Ukungagqibeki kwenethiwekhi kutshatyalalisiwe

virsh # umnatha-ukuqala okumiselweyo
Ukungagqibeki kwenethiwekhi kuqalile

uluhlu lwe-virsh # net-yonke
 Igama I-State Autostart eqhubekayo -------------------------------------------------- ------------ sisebenza ewe ewe

i-virsh # net-info engagqibekanga
Igama: i-UUID emiselweyo: 2a2ef469-3008-45f9-a165-ab1fb8f6277b Iyasebenza: ewe iyaqhubeka: ewe Autostart: ewe Bridge: virbr0
