问题描述

I have problem about starting my gunicorn - Flask app on my server. 我在服务器上启动我的gunicorn-Flask应用程序时遇到问题。

My server is Ubuntu 14.04 64 bit. 我的服务器是Ubuntu 14.04 64位。

When I start gunicorn from terminal (and have virtual environment active): 当我从终端启动gunicorn（并激活虚拟环境）时： 

gunicorn --bind 0.0.0.0:8000 wsgi

it works, I can connect with port 8000. 它可以工作，我可以连接端口8000。

but when I want to start sudo service MyApp , it gives me following error: 但是，当我想启动sudo service MyApp ，出现以下错误： 

start: Job failed to start

my /etc/init/MyApp.conf is: 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

NOTE: 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 我知道我还没有创建MyApp.sock，我不知道是否必须创建该脚本或我创建了MyApp.sock

Where should be a problem? 哪里应该有问题？

UPDATE: from terminal, this command is working: 更新：从终端，此命令正在工作：

I think the line 我认为线 

chdir /home/juldou/MyApp

doesn't change directory to the where wsgi is located. 不会将目录更改为wsgi所在的位置。

Try changing /home/juldou/MyApp to the path where you can run it form the terminal. 尝试将/home/juldou/MyApp更改为可以从终端运行它的路径。
