Vikela uhlelo lwe-Grub2 ngegama lomsebenzisi nephasiwedi (umbhalo)

I-Grub2 inguqulo ethuthukisiwe ye- Grub (I-GNU Grand Unified Bootloader), i-Linux bootloader eyafika ngonyaka we-1999 ngenxa yokuthuthukiswa kuka-Yoshinori Okuji, ngomqondo wokunikeza uhlelo lokusebenza lwe-penguin ithuluzi lesimanje kusukela i-LILO, yize yayizinzile futhi ivikelekile kakhulu, ayizange unikele ngamathuba amaningi kakhulu ngekusasa. Kanjalo, I-Grub2 iyingxenye ebalulekile yokusebenza nokuphepha kwekhompyutha yethu, ngakho-ke kubalulekile ukubona ukuthi singanakekela kanjani ukuthi kutholakala bani, kanjani futhi nini.

Njengoba iningi labafundi bethu lizokwazi impela, I-Grub2 Kungavikeleka ngendlela yokuthi sikwazi ukufinyelela kuphela izinketho zayo ngokufaka igama lomsebenzisi nephasiwedi, into engeke yeqe ngokuphelele kepha okungenani isinikeza ukuphepha okuthile futhi izobambezela izinto kulabo abazama ukufinyelela ngaphandle kwemvume i-Linux boot loader. Futhi kulokhu okuthunyelwe sizobona ungayivikela kanjani iGrub2 ngegama lomsebenzisi nephasiwedi (umbhalo).

Inqubo ye- qinisekisa imodi eyodwa yomsebenzisi, kanye ne-Emergency and Rescue, ukuthi izosisiza kuRet Hat Enterprise Linux, Fedora noma kuCentOS 7, futhi lokho kudinga kuphela izinyathelo ezimbalwa njengoba sizobona ngezansi:

Okokuqala singena ngemvume njengomlawuli (noma siphakamisa amalungelo ethu sisebenzisa umyalo 'su') ngoba sizohlela ukumiswa kweGrub. Kepha ngaphambi kwalokhu sakha ikhophi yokusekelayo yamafayela awuphethe:

cp /boot/grub2/grub.cfg /boot/grub2/grub.cfg.original
cp /etc/grub.d/10_linux /etc/grub.d/10_linux.original

Manje sivula ifayela le-10_linux:

sudo vi /etc/grub.d/10_linux

Futhi sifaka okulandelayo komsebenzisi nephasiwedi (ukufaka lawo magama esikhundleni salokho esikukhethayo):

cat << EOF
set superusers="willy" password willy contraseñadewilly
EOF

Lapha umsebenzisi willy uzoba ne-password 'iphasiwedidewilly', futhi livela esigabeni 'sabasebenzisi abakhulu' ngoba yilo kuphela elingafinyelela noma yikuphi ukungena kwemenyu ye-Grub, lihlele (ngokucindezela u-'e '), noma lisebenzise imodi yomugqa womyalo walo (ngokucindezela u-'c').

Manje sakha iGrub.cfg entsha:

grub2-mkconfig --output=/tmp/grub2.cfg

Manje sesifaka ifayili lokumiswa kweGrub ngaleli esilidalile:

mv /tmp/grub2.cfg /boot/grub2/grub.cfg

Yilokho kuphela, esingaqala kabusha futhi lapho sibona isikrini seGrub singacindezela u-'e ', ngemuva kwalokho sizocelwa iphasiwedi esiyifakile kufayela lokumisa.
