Capistrano部署:从独角兽开始

Question

使用capistrano进行部署.一切顺利,然后部署:启动(部署:冷),它会产生一个错误:

  * ?[32m2013-03-14 15:03:05 executing `deploy:start'?[0m
  * ?[33mexecuting "/etc/init.d/unicorn_appname start"?[0m
    servers: ["XXX.XXX.131.4"]
    [XXX.XXX.131.4] executing command
 ** [out :: XXX.XXX.131.4] sh: /etc/init.d/unicorn_appname: not found
    ?[2;37mcommand finished in 1572ms?[0m
failed: "sh -c '/etc/init.d/unicorn_appname start'" on XXX.XXX.131.4

有问题的文件存在.这是它的内容:

    done
    echo

      echo >&2 "$OLD_PIN still exists after $TIMEOUT seconds"
      exit 1

    exit 0

试图通过ssh(sh -c'/ etc/init.d/unicorn_appname start')运行命令后,我遇到了同样的错误.

可能是什么原因？

谢谢大家的建议。问题终于解决了。事实证明，问题是从 Windows 计算机部署的 - .sh 文件具有 Windows 样式的行结尾，并且 unix 无法正确读取。解决方案是相应地更改 IDE 设置（对于 Rubymine：文件->设置->代码样式->常规->行分隔符->unix）并重新创建文件。然后： git add . git commit -m “修复” git Push cap 部署：设置 cap 部署：冷

完毕！再次感谢大家！

PS：有人知道为什么资产管道部署后无法工作吗？
