Recebi a tarefa de colocar uma instância do chiliproject online novamente. Ele está sendo executado em um servidor do CentOS 6 (64 bits). O problema é que eu sei absolutamente zero Ruby, e meu conhecimento de Linux não é muito mais avançado do que isso; Não tenho a menor ideia de por onde começar.
Quando carrego a página em um navegador, o seguinte é gravado em /var/log/nginx/redmine-proxy-error :
2014/01/13 11:52:06 [crit] 1865#0: *675 connect() to unix:/var/run/redmine/sockets/thin.3.sock failed (2: No such file or directory) while connecting to upstream, client: IPADDRESSHERE, server: REDACTED.com.br, request: "GET / HTTP/1.1", upstream: "http://unix:/var/run/redmine/sockets/thin.3.sock:/", host: "REDACTED.com.br"

Eu recebi ajuda do #chiliproject no IRC:
thin is an app server which (in your case) seems to be tasked to run the actual chiliproject code. It has to be started seperately from nginx, and should then (according to your config) create a listening socket at /var/run/redmine/sockets/thin.3.sock where your nginx forwards connections to. You might have a seperate init script for thin already. Or else you might have to start it using script/server or the thin executable inside your chiliproject dir. You probably have a thin config file somewhere (something like redmine.yml, e.g. in /etc/thin), it should contain (in human readable form) some config settings for thin, including the socket location, your chiliproject directory and other stuff. You can start thin by running thin start -C /etc/thin/redmine.yml
Aqui está o meu /etc/thin/redmine.yml (o único arquivo neste diretório):
---
chdir: /srv/www/redmine/chiliproject
environment: production

E aqui está o /etc/rc.d/init.d/thin :

esac
:
Não há arquivo /usr/local/rvm/bin/bootup_thin .
Eu reinicio a máquina e executo ps aux | grep thin não me mostra nada (além do próprio grep).
Se eu executar start -C /etc/thin/redmine.yml , obtenho uma saída de texto na tela e inicio em thin e posso navegar pelo site. Se eu reiniciar a máquina, o serviço não será carregado corretamente, apesar do arquivo init.d . Este arquivo está sendo executado, porque eu coloquei uma linha touch /var/log/test na cláusula start) e o arquivo foi criado. Eu também adicionei > /var/log/thin_output ao final da linha de partida, mas ele cria e arquiva o arquivo, e os thin logs não mostram que ele está sendo iniciado.
Incluir start -C /etc/thin/redmine.yml no final de /etc/rc.local também não tem efeito.
A saída de type thin é
thin is /usr/local/rvm/gems/ruby-1.9.2-p290/bin/thin
Se eu digitar /etc/init.d/thin start , ele será iniciado com uma saída normal:
Starting server on /var/run/redmine/sockets/thin.0.sock ...
Starting server on /var/run/redmine/sockets/thin.1.sock ...
Starting server on /var/run/redmine/sockets/thin.2.sock ...
Starting server on /var/run/redmine/sockets/thin.3.sock ...
Foi-me perguntado no chat para colar a saída de find -L /etc/ -samefile /etc/init.d/thin , é:
/etc/rc2.d/K50thin
/etc/rc0.d/K50thin
/etc/rc5.d/K50thin
/etc/init.d/thin
/etc/rc.d/rc2.d/K50thin
/etc/rc.d/rc0.d/K50thin
/etc/rc.d/rc5.d/K50thin
/etc/rc.d/init.d/thin
/etc/rc.d/rc3.d/K50thin
/etc/rc.d/rc1.d/K50thin
/etc/rc.d/rc4.d/K50thin
/etc/rc.d/rc6.d/K50thin
/etc/rc3.d/K50thin
/etc/rc1.d/K50thin
/etc/rc4.d/K50thin
/etc/rc6.d/K50thin
Eu executei sudo chkconfig thin on como sugerido em uma resposta aqui e chkconfig -l thin outputs
thin 0:off 1:off 2:on 3:on 4:on 5:on 6:off
e a saída de find -L /etc/ -samefile /etc/init.d/thin muda para /etc/rc2.d/S50thin /etc/rc0.d/K50thin /etc/rc5.d/S50thin /etc/init.d/thin /etc/rc.d/rc2.d/S50thin /etc/rc.d/rc0.d/K50thin /etc/rc.d/rc5.d/S50thin /etc/rc.d/init.d/thin /etc/rc.d/rc3.d/S50thin /etc/rc.d/rc1.d/K50thin /etc/rc.d/rc4.d/S50thin /etc/rc.d/rc6.d/K50thin /etc/rc3.d/S50thin /etc/rc1.d/K50thin /etc/rc4.d/S50thin /etc/rc6.d/K50thin ; mas quando eu reinicio, o thin ainda não está rodando.
Alguém sugeriu que eu comparasse as variáveis de ambiente em diferentes níveis de execução, então incluí printenv > /var/log/printenv.log em uma linha de /etc/rc.d/init.d/thin e a comparei com a saída de printenv na CLI. Aqui estão os resultados:
