Virsh command - Shabakadaha Kombuyuutarada ee SMEs

Tusmada guud ee taxanaha: Shabakadaha Kombuyuutarka ee loogu talagalay SMEs: Hordhac

Saaxiibayaal waad salaaman tihiin!

Haddii aad na raacday annaga oo akhrinaya qodobbada illaa iyo hadda la daabacay, waxaad ogaan doontaa inaan raacno waddo macquul ah, si aan uga helno xarun shaqo ama sheybaar guriga, annaga oo leh taageerada lagama maarmaanka u ah aalado farsamo ama server oo aan ku fulin doono adeegyada ugu yar a LAN - Shabakadda Aagga ee Degmada Ganacsiga.

Waxaan u qaadaneynaa inaad aqrisay:

• Shabakadaha Kombuyuutarka ee loogu talagalay SMEs: Hordhac
• Rakibaadda Goobta Shaqada - Shabakadaha Kombiyuutarada ee SMEs
• 6 Debian Desktops - Isku xirka kombiyuutarka ee SMEs

Xidhiidhyadii hore, iyo sidoo kale xiriidhada dibedda ee bogagga iyo boggaga kaladuwan ee ay ku jiraan macluumaadka hodanka ah, ee lagu daray maqaal kasta, waxaa lagu bixiyaa ujeeddada ah inaad ku kasbato aqoon aasaasi ah oo ku saabsan mowduucyada kala duwan ee laga hadlay.

Mashruucani waa sii socoshada macquul ee wadada la doortay. Akhriskaaga iyo daraasaddaadu waxay kuu oggolaaneysaa inaad fikrad ka haysato adduunka ballaadhan ee ah Gudbinta iyada oo loo marayo Qemu-KVM iyo dukaanka buugaagta ugu weyn libvirt.

Virsh - Isugeynta adeegsadaha guud ee maaraynta Domains Virtual

Waxaan ka ognahay akhrintii hore in Virtualization-ka Linux uu macnahiisu yahay awood u leh inuu socodsiiyo dhacdooyin badan oo nidaamyo kaladuwan oo isku mid ah, isla madal hardware ah. libvirt waa qalab ay ku qoran tahay luqadda C, taas oo noo oggolaaneysa inaan la falgalno awoodaha waxqabadka ee noocyada ugu dambeeyay ee Linux, iyo sidoo kale kuwa nidaamyada kale ee hawlgalka.

Waan isticmaali karnaa barnaamijka barato si loo abuuro, loo hakiyo, loo xidho, liiska, iyo hawlo badan oo dheeri ah oo ku saabsan meertooyinka dalwaddii iyo kormeerayaashii martigelin lahaa. Magaca barnaamijka ayaa soo jeedinaya inuu gaaban yahay «Virtujin Shisagu»Ama Processor-ka amar ku taagleynta.

Qaab guud waxaan ugu yeeri karnaa sida:

virsh [OPTION] .... [Doodda] ...

• amar: wuxuu ka mid noqon karaa 215 amar ku taxan goor dambe
• domain: magaca magaca ama mashiinka farsamada, ama Aqoonsiga aqoonsiga lambar, ama UUID ee bogga.
• doodaha: xulashooyinka u gaarka ah amar kasta

Waxaa jira dhowr waxyaalood oo ka reeban sharcigii hore, sida kiisaska amarku uu ku dhaqmayo dhammaan meerisyada, mashiinka, ama tooska Xen Hypervisor - XenHypervisor. Ka-reebitaannada noocaas ah ayaa loo fasaxay amar kasta.

Nota: In kasta oo ay ansax tahay in lagu aqoonsado mishiin kumbuyuutareed aqoonsi nambarkiisa, haddana qiimahan tirooyinka ah ayaa had iyo jeer loo tarjumi doonaa inuu yahay aqoonsi domain ah, oo aan loo aqoonsan doonin magaciisa.

ka Virsh amarka XULASHADA Waxay yihiin:

• -c, –ku xidhnow URI: Kuxirayaa URI «Aqoonsiga Labiska Dharka- Aqoonsiga Labiska Dharka, halkii laga heli lahaa URI-da caadiga ah oo ah kan hypervisor-ka maxalliga ah.
• -d, –dhibic Heerka: Awoodda farriimaha khaladka - Debug, illaa qiimaha isku-darka 'LEVEL', dood xaddidan oo qaadan karta qiyamka u dhexeeya 0 iyo 4. Si hufan 4 waa qiimaha asalka ah.
• -e, –halka baxsiga: Waxay dejisaa taxane dabeecad kale ah waayo, markaan riixno «furahaEsc«. Tixraaca asalka ah waa ^]. Astaamaha la oggol yahay waa: dabeecad kasta oo xarfo ah, @, [,], \, ^, _. Waxaan soo jeedinaynaa ha ka beddelin isku xigxiga dabeecadda asalka ah.
• -h, –help: Wuu iska indhatiraa doodaha kale wuxuuna u dhaqmaa sidii isagoo amarka fulinaya I caawi.
• -k, –xakamaynta-joogitaanka INTERVAL: Waxay dejisaa bareeg ilbiriqsiyo ah si ay u diraan farriimaha nooca ilaalin, si loo hubiyo in isku xirka serverka wali nool yahay. Haddii qiimaha ay INTERVAL ayaa lagu wadaa 0, markaa farsamadan hubinta ayaa shaqeynaysa.
• -K, –xisaab-tirinta COUNT: Wuxuu dejiyaa tirada jeer ee farriinta la diri karo ilaalin adigoon jawaab ka helin serverka, isla markaana aan calaamadin isku xidhka inuu dhintay. Wax saameyn ah kuma yeelan doonto doorashadan, haddii qiimaha INTERVAL ee ikhtiyaari hore loo dhigay 0.
• -l, –GAL FILE: Wuxuu u jiheeyaa wax soo saarka hawsha faylka FILE.
• -q, – xasilloon: Ka fogow macluumaadka dheeriga ah ee farriimaha ah. Habka aamusnaanta.
• -r, – akhrinta keliya: Xiriirinta bilowga ah waxaa lagu aasaasay Akhriso kaliya. La mid ah marka aan isticmaalno ikhtiyaarka –Kala hadal amar ahaan xirmaan.
• -t, –marka: Wuxuu muujiyaa waqtiga ay wada cuneen amar kasta.
• -v, –version = gaabin: Iska dhaaf dood kasta oo kale, oo muuji kaliya nooca maktabadda libvirt barnaamijku wuxuu ka yimaadaa barato.
• -V, – rogitaan = dheer: Iska dhaaf wixii dood ah oo tus nooca maktabadda libvirt barnaamijku wuxuu ka yimaadaa barato iyo waliba, kala-sarreyaasha kala duwan, kormeerayaasha - darawallada, noocyada shabakada, iwm oo ay soo uruurintu taageerto.

Notas:

• Inta badan hawlgallada taliska barato, ka soo qaad in dukaanka buugaagta lagu iibiyo libvirt awoodo inaad ku xirto adeeg libvirtd ficil ahaan.
• Amarada badankood waxay u baahan yihiin in lagu maamulo mudnaanta isticmaalaha xidid sababo la xiriira dariiqa isgaarsiinta ee ay u isticmaasho inay kula xiriiraan Hypervisor. Haddii ay la socoto mudnaanta isticmaale caadi ah, waxay soo celin doontaa qalad.
• Amarada badankood waxay u shaqeeyaan si isku mid ah. Waxyaabaha ka reeban ayaa ah xiritaanka, setvcpus y gogol. Xaaladahaas, xaqiiqda ah in barato soo celi isla markiiba amar, macnaheedu maahan in ficilku si guul leh ku dhammaaday. Waa in marmar la hubiyaa si loo ogaado in hawlgalku ku dhammaaday Martida - Guest.

Wixii macluumaad dheeraad ah ee ku saabsan waxyaabaha ku jira, eeg nin virsh.
