python - gunicorn:开始:作业无法启动

Question

我在启动我的 gunicorn - 我的服务器上的 Flask 应用程序时遇到问题。

我的服务器是 Ubuntu 14.04 64 位。

当我从终端启动 gunicorn(并激活虚拟环境)时:

gunicorn --bind 0.0.0.0:8000 wsgi

它有效，我可以连接到端口 8000。

但是当我想启动 sudo service MyApp 时，出现以下错误:

start: Job failed to start

我的/etc/init/MyApp.conf 是:

description "Gunicorn application server running MyApp"

start on runlevel [2345]
stop on runlevel [!2345]

respawn
setuid juldou
setgid  www-data

env PATH=/home/juldou/MyApp/project_juda/bin
chdir /home/juldou/MyApp
exec gunicorn --workers 3 --bind unix:MyApp.sock -m 007 wsgi

注意:

I know that I don't have created MyApp.sock, I don't know if I must have or this script create MyApp.sock

应该是哪里出了问题？

更新:从终端，此命令正在运行:

(project_juda) juldou@ubuntu-512mb-fra1-01-improveyourself:~/MyApp$ gunicorn --workers 3 --bind unix:MyApp.sock -m 007 wsgi

Answer 1

我觉得行

chdir /home/juldou/MyApp

不会将目录更改为 wsgi 所在的位置。

尝试将 /home/juldou/MyApp 更改为您可以从终端运行它的路径。
