Qual é a maneira correta de atualizar um script de inicialização em um sistema Ubuntu?
Estou tentando atualizar minha versão do gitlab de 6-0 para 6-1. Parte da atualização consiste em substituir o script de inicialização.
Instruções de atualização - etapa 6
sudo rm /etc/init.d/gitlab
sudo curl --output /etc/init.d/gitlab https://raw.github.com/gitlabhq/gitlabhq/6-1-stable/lib/support/init.d/gitlab
sudo chmod +x /etc/init.d/gitlab
Acho que depois de atualizar o script de inicialização, o script de chamada não faz nada. Normalmente imprime o id do processo do serviço gitlab
root@gitlab:/etc/init.d# /etc/init.d/gitlab status
root@gitlab:/etc/init.d# (notice how nothing happens)
#No gitlab process is running
root@gitlab:/etc/init.d# ps aux |grep gitlab
root 4519 0.0 0.1 9384 928 pts/0 R+ 20:03 0:00 grep --color=auto gitlab
Etapas que tomei para solucionar isso:
Certifique-se de que é executável
root@gitlab:/etc/init.d# ll gitlab
-rwxr-xr-x 1 root root 7195 Sep 28 19:29 gitlab*

Estou mais familiarizado com o Cent do que com o Ubuntu e ouço opiniões divergentes sobre a execução manual do update-rc.d. Eu tentei de qualquer maneira pela sugestão deste blog
%pre%Sem sorte, o script ainda não funciona.
Há mais alguma coisa que deve ser feita em sistemas Ubuntu para atualizar scripts de inicialização?
Update1:
Observando /var/log/auth.log mostra:
%pre%Update2
Eu fiz um diff dos scripts init entre 6-0-stable e 6-1-stable. Parece ter sido uma reescrita quase completa.
A diferença está localizada aqui:
link
Você pode ver o script real 6-0 aqui:
e o script 6-1 aqui:
Update3
Tentei começar o script usando o bash -x
%pre%Parece que o script deve ser executado como o usuário 'git'.
Eu descobri a solução para o problema que não requer a mudança do script de inicialização.
As instruções para o gitlab instruem o usuário a usar adduser --disabled-login . Em vez de usar adduser , usei o fantoche para adicionar o usuário e definir o shell padrão como / bin / false em vez de / bin / bash.
Assim que mudei o shell do meu 'git' para / bin / bash, o script init começou a funcionar corretamente novamente.
