Recuperar CentOS sem YUM e RPM

Question

Esta é a história:

Eu tenho (ou tinha) uma caixa linux com CentOS 5.9 e uma configuração LAMP pré-instalada. Ele estava funcionando, mas estava muito desatualizado, por exemplo, o mysql era a versão 4. Então, decidi atualizar tudo com yum .

Estranhamente, meu sqlite era 3.6, o que é mais novo que 3.3, listado como uma dependência para PHP, Apache e subversão mais recentes, então yum parou de atualizar e reclamou disso.

Então eu fiz uma coisa muito errada: usei yum erase sqlite para remover o sqlite antigo (e mais novo) do meu sistema. Neste ponto, o yum removeu o sqlite e todos os outros pacotes que o continham como dependência. Isso incluiu basicamente tudo:)

Agora eu ainda tenho acesso ssh à minha caixa, mas apache, mysql, php, foi embora, muitas outras coisas foram excluídas também, incluindo o pacote de desenvolvimento, o rpm e o próprio yum.

Tenho experiência com o Debian e o apt-get, e mal consigo acreditar que fiz isso nos primeiros 30 minutos em uma máquina centos com o yum. Agora eu não tenho ideia de como consertar isso.

Eu encontrei como instalar o yum a partir de um arquivo rpm, ou rpm do yum, mas já que não tenho nenhum ...

Na minha raiz eu tenho este arquivo: initrd-2.6.18-308.13.1.el5.centos.plus.img Eu imagino que é uma imagem do meu sistema como pré-instalado, mas eu não tenho ideia de como recuperar meu sistema deste arquivo.

Alguém pode me ajudar com isso?

Você pode tentar extrair os seguintes pacotes em outro host:

link link

e depois copie os arquivos binários com scp / wget / rsync. Eu tentei em estações de trabalho vmware e tudo funciona bem

Answer 2

Você pode tentar os seguintes comandos

# cd /mnt
# zcat /root/initrd-2.6.18-308.13.1.el5.centos.plus.img | cpio -i

Mas acho que isso não resolve o seu problema. Você pode tentar baixar o dvd entos, montá-los e instalar todos os pacotes necessários

# cd /root 
# wget http://mirror.mirohost.net/centos/5.9/isos/x86_64/CentOS-5.9-x86_64-bin-DVD-1of2.iso
# mount -o loop /root/CentOS-5.9-x86_64-bin-DVD-1of2.iso /mnt

P.S. Você pode ver todos os pacotes removidos em / var / log / messages
