Ruby on rails Unicorn/Nginx部署-未创建Unicorn.sock（导致502错误）

我的主要问题是，在尝试访问我的应用程序时，我收到了502网关错误（标准的“出错了”-rails错误，但控制台说是502）

检查nginx错误日志会显示以下内容：

2015/05/10 20:06:09 [crit] 32270#0: *10 connect() to unix:/var/sockets/unicorn.depot.sock failed (2: No such file or directory) while connecting to upstream

/home/deployer/apps/depot/current# bundle exec unicorn --restart
bundler: command not found: unicorn

实际上，/var/sockets中没有文件

最初，我将套接字路径设置为/tmp，但读取后，/tmp文件夹中的文件只能由创建它们的服务访问，我将它们移动到/var文件夹中

但是还有更多的问题——pid文件也没有创建

在继续我的配置文件之前-我有一种奇怪的感觉，我的unicorn_init.sh中的这一行可能会导致问题：

CMD="cd $APP_ROOT; bundle exec unicorn -D -c $APP_ROOT/config/unicorn.rb -E production"

因为当我手动执行时，我会收到以下信息：

2015/05/10 20:06:09 [crit] 32270#0: *10 connect() to unix:/var/sockets/unicorn.depot.sock failed (2: No such file or directory) while connecting to upstream

/home/deployer/apps/depot/current# bundle exec unicorn --restart
bundler: command not found: unicorn

但是，我害怕通过捆绑安装在vps上安装unicorn（unicorn当然包括在我的Gemfile中），正如shell告诉我的：

/home/deployer/apps/depot/current# bundle install  
Don't run Bundler as root. Bundler can ask for sudo if it is needed, and 
installing your bundle as root will break this 
application for all non-root users on this machine.

我将感谢任何反馈，提前感谢

以下是我的配置文件：

我也有这个问题！你的问题解决了吗？怎么做？@ryan2johnson 9不幸的是-没有。我完全改用彪马而不是独角兽，使用了这本很棒的教程：像一个魔咒一样工作！好的-这对你没有帮助，但也许有一天会有其他人：我在部署后手动重启我的独角兽应用程序，摆脱了麻烦。Capistrano部署使用run

task:restart do invoke'unicorn:legacy_restart'end

，但这似乎没有将套接字放在正确的位置，但是从in-server手动重新启动bundle exec unicorn-D-c/home/deploy/apps/my_-app/current/config/unicorn/staging.rb-E staging
