rails cap implanta problemas de unicórnio

Question

Tentando usar o aplicativo rails implantado. Tudo está instalado nginx, unicornio, setup.

Erro ao obter:

    [109.etc] env RAILS_ENV=production sh -c 'kill -s USR2 '\''cat /tmp/unicorn.pid'\'''
    sh: line 0: kill: cat /tmp/unicorn.pid: arguments must be process or job IDs

Como isso pode ser corrigido? Eu procurei por uma hora uma leitura em muitos docs e blogposts, ainda não encontrei a solução.

UPDATE

Ao executar o comando start do unicórnio no servidor:

bundle exec unicorn_rails -c config/unicorn.rb -D
/usr/local/rvm/gems/ruby-1.9.3-p125/gems/bundler-1.1.1/lib/bundler.rb:255: warning: Insecure world writable dir /srv in PATH, mode 040777

Minhas permissões para / srv / drwxr - r-- 4 raiz do root 4096 Mar 15 19:14 srv * não tenho certeza se estão certos

    

Answer 1

unicorn_rails -E production -c $APP_PATH/config/unicorn.rb -D deve ser tudo que você precisa. Então, olhando para o seu código, você está perdendo seu sinalizador de env ( -E ) se você tiver que usar o pacote dessa maneira.
