我是新来的,所以要温柔.

我最近建立了一个新的VPS来运行ruby-on-rails网站.我已经使用上述版本安装了以下应用程序.我收到Bad Gateway错误.我浏览了网络和stackoverflow,但未能隔离任何有关此错误的讨论.

请有人对此有所了解.
感谢您的投入.

错误日志 – 将passenger_log_level设置为7.下面的主要位,我还可以上传一个txt文件,如果我能弄清楚如何.

我能发现的主要错误代码就是这个.一旦发出请求,它就会进入无限循环：

2015-01-14 16:38:49.7008 2348/7fa01e892700 agents/HelperAgent/RequestHandler.h:2626 ]: [Client 20] End of (unbuffered) client body reached; done sending data to application

当nginx / passenger启动时,我也注意到了下面的一次：

[ 2015-01-14 16:38:46.8338 2348/7fa0209bf700 Pool2/SmartSpawner.h:353 ]: [App 2367 stdin >>]

nginx是通过/etc/init.d/nginx脚本启动的,主要是这样做的：

case "$1" in
  start)
        echo -n "Starting $DESC: "
        start-stop-daemon --start --quiet --pidfile /opt/nginx/logs/$NAME.pid                 --exec $DAEMON -- $DAEMON_OPTS
        echo "$NAME."
        ;;

解决方法:

我从来没有完全按照上面的设置工作.最后,我将乘客升级到4.0.57,这很有效！
