O SELinux está impedindo que o nginx tenha acesso de gravação no soquete Unicorn

Question

Estou tentando configurar meu aplicativo Rails com Nginx e Unicorn.

O Nginx lança o seguinte erro ao acessar a URL raiz do meu aplicativo Rails:

дек 14 23:39:42 servercentos7 python[5604]: SELinux is preventing /usr/sbin/nginx from write access on the sock_file /var/www/amily_photo/shared/tmp/sockets/unicorn.sock.

                                           *****  Plugin catchall (100. confidence) suggests   **************************

                                           If you believe that nginx should be allowed write access on the unicorn.sock sock_file by default.
                                           Then you should report this as a bug.
                                           You can generate a local policy module to allow this access.
                                           Do
                                           allow this access for now by executing:
                                           # grep nginx /var/log/audit/audit.log | audit2allow -M mypol
                                           # semodule -i mypol.pp

Eu executei dois comandos, mencionados no relatório de erros, mas não funciona

grep nginx /var/log/audit/audit.log | audit2allow -M mypol
semodule -i mypol.pp

nginx.conf:

worker_processes 1;

user root root; # for systems with a "nogroup"

# Feel free to change all paths to suite your needs here, of course

Estas mensagens não ajudaram:

• erro nginx conectar-se ao php5-fpm .sock falhou (13: Permissão negada)
• Ajuda do SELinux - 5.2. Restaurar contextos de segurança padrão

Eu não tenho ideia do que fazer…

Por favor, ajude.
