运用supervisord管理后台运行程序, 以及注意事项

来源:互联网 发布:win10 怎么修改mac 编辑:程序博客网 时间:2024/06/05 09:22

1. 安装 sudo pip install supervisor

2. 添加配置文件: sudo echo_supervisord_conf > /etc/supervisord.conf

3. 设置开机启动:

Supervisor is not running at startup. You can configure an init.d script to do this.

sudo vi /etc/init.d/supervisord

Add the following:

# Supervisord auto-start## description: Auto-starts supervisord# processname: supervisord# pidfile: /var/run/supervisord.pidSUPERVISORD=/usr/local/bin/supervisordSUPERVISORCTL=/usr/local/bin/supervisorctlcase $1 instart)        echo -n "Starting supervisord: "        $SUPERVISORD        echo        ;;stop)        echo -n "Stopping supervisord: "        $SUPERVISORCTL shutdown        echo        ;;restart)        echo -n "Stopping supervisord: "        $SUPERVISORCTL shutdown        echo        echo -n "Starting supervisord: "        $SUPERVISORD        echo        ;;esac

And then...

sudo chmod +x /etc/init.d/supervisord
sudo update-rc.d supervisord defaults
sudo /etc/init.d/supervisord start

Obviously, this should probably go as added actions on cookbook.py and the init.d script as a template


遇到的问题


exit too quick

这个可能是某些python的库没有安装,然后也不报错

还有可能是之前启动没有成功,但是进程已经存在了,这里要手工kill掉之前的app进程再stall all


abnormal termination:

这个可以这样测试,如果不用supervisord来管理能正常运行的话,那一般是代码中可能有输出异常字符,比如中文什么的,解决办法有几个,最简单的就是去掉类似print 输出中文的地方 , 这个错误很郁闷,不会报错,但就是用supervisord运行不起来
