Iketsetse Bare-Metal Provisioning, kapa ho itokisa ka boiketsetso ha li-server ho tloha qalong

Lumela, ke 'na Denis' me e 'ngoe ea libaka tseo ke sebetsang ho tsona ke nts'etsopele ea litharollo tsa litšebeletso tsa motheo ho X5. Kajeno ke rata ho arolelana le uena kamoo u ka sebelisang mokhoa oa ho itokisa oa seva o ipapisitseng le lisebelisoa tse fumanehang phatlalatsa. Ka maikutlo a ka, ena ke tharollo e thahasellisang, e bonolo le e bonolo.

Ka ho itokisa re bolela: fetola seva e ncha ka ntle ho lebokose hore e be seva e hlophisitsoeng ka botlalo e nang le OS. Linux kapa ka hypervisor ea ESXi (ho tsamaisoa ha li-server tsa Windows ha ho buuoe sehloohong sena).

Lipehelo:

• li-server - li-server tse hlokang ho hlophisoa.
• ho kenya seva ke sesebelisoa se seholo se fanang ka ts'ebetso eohle ea ho itokisa holim'a marang-rang.

Hobaneng ho hlokahala?

Ha re re ho na le mosebetsi: ho lokisa li-server ka matla ho tloha qalong, tlhōrōng - 30 ka letsatsi. Li-server tsa bahlahisi le mehlala e fapaneng, litsamaiso tse fapaneng tsa ts'ebetso li ka kengoa ho tsona, 'me li kanna tsa ba le hypervisor kapa tsa se be teng.

Ke lits'ebetso life tse kenyellelitsoeng ts'ebetsong ea ho seta (ntle le boiketsetso):

• hokela keyboard, mouse, leihlo ho seva;
• lokisa BIOS, RAID, IPMI;
• ntlafatsa karolo ea firmware;
• tsamaisa setšoantšo sa sistimi ea faele (kapa kenya hypervisor le ho kopitsa mochini o hlakileng);

Hlokomela. Ntle le moo, ho tsamaisoa ha OS hoa khoneha ka ho kenya ka faele ea karabo ea auto. Empa sena se ke ke sa tšohloa sehloohong sena. Le hoja u tla bona ka tlase hore ho eketsa tshebetso ena ha ho thata.

• lokisa maemo a OS (lebitso la moamoheli, IP, joalo-joalo).

Ka mokhoa ona, litlhophiso tse tšoanang li etsoa ka tatellano ho seva ka seng. Ts'ebetso ea mosebetsi o joalo e tlase haholo.

Ntho ea bohlokoa ea ho iketsetsa ke ho felisa ho kenya letsoho ha batho ho tloha ts'ebetsong ea ho lokisa seva. Ka hohle kamoo ho ka khonehang.

Automation e fokotsa nako pakeng tsa ts'ebetso mme e etsa hore ho khonehe ho fana ka li-server tse ngata ka nako e le 'ngoe. Monyetla oa liphoso ka lebaka la lintlha tsa batho le ona o fokotsehile haholo.

Li-server li hlophisoa joang ka bo eona?

A re hlahlobeng mekhahlelo eohle ka botlalo.

U na le seva ea Linux eo u e sebelisang e le seva sa ho kenya PXE. Litšebeletso li kentsoe le ho hlophisoa ho eona: DHCP, TFTP.

Kahoo, re qalisa seva (e hlokang ho hlophisoa) ka PXE. A re hopoleng hore na e sebetsa joang:

• Boot boot e khethiloe ho seva.
• Seva e laela PXE-ROM ea karete ea marang-rang ebe e ikopanya le seva sa ho kenya ka DHCP ho fumana aterese ea marang-rang.
• Seva ea ho kenya DHCP e fana ka aterese, hammoho le litaelo tsa ho khoasolla hape ka PXE.
• Seva e jarisa bootloader ea marang-rang ho tloha ho seva sa ho kenya ka PXE, ho kenya ho eketsehileng ho etsahala ho latela faele ea tlhophiso ea PXE.
• Boot e hlaha ho latela litekanyo tse amoheloang (kernel, initramfs, mount points, squashfs image, joalo-joalo).

Hlokomela. Sengoloa se hlalosa ho qala ka PXE ka mokhoa oa BIOS. Hajoale, bahlahisi ba ntse ba kenya tšebetsong UEFI bootmode. Bakeng sa PXE, phapang e tla ba ho tlhophiso ea seva sa DHCP le boteng ba bootloader e eketsehileng.
