Compilei o nginx com caminhos personalizados para o meu servidor de produção e quando tento iniciar / reiniciar o serviço usando:
service nginx start
ou
service nginx restart
Ele entra em uma nova linha sem retornar o shell:
Portanto, o problema é que não consigo controlar o nginx usando o servicecomando O serviço realmente é executado, mas ele não retorna um shell para mim, então eu sempre tenho que pressionar ctrl+ cpara recuperá-lo.
Também devo mencionar que o nginx funciona muito bem quando o chama por seu próprio nginxcomando e para ou recarrega facilmente usando nginx -s stop/reload.
Esse problema também persiste systemctl start nginx, mas systemctl stop nginxfunciona bem.

Tente rastrear o problema. Ele mostrará como a chamada do sistema não pode ser concluída. Basta instalar o strace e, em seguida, strace -ff service nginx start.

journalctle straceaqui, mas sinceramente eu não tenho idéia de como entender o problema da saída do strace. eu apreciaria um pouco de ajuda, se possível.
@ T0M XeOn LuCiFeR você corrigiu esse problema?

nginxestá funcionando bem ao iniciar a partir de um CLI, é necessário depurar o script de serviço .
