Supervisor安装及配置

Supervisor安装

# 安装
easy_install supervisor
# 生成默认配置文件
echo_supervisord_conf > /etc/supervisord.conf
mkdir /etc/supervisord.conf.d

修改配置文件

include区段修改为

[include]
files = /etc/supervisord.conf.d/*.conf

如需要访问web控制界面，inet_http_server区段修改为

[inet_http_server]
port=0.0.0.0:9001
username=username ; 你的用户名
password=password ; 你的密码

每个需要管理的进程分别写在一个文件里面，放在/etc/supervisord.conf.d/目录下，便于管理。例如：test.conf

[program:sqlparse]
directory = /var/www/python
command = /bin/env python test.py

将supervisord加入系统服务，以下代码来自gist，文件：/etc/init.d/supervisord

#!/bin/sh
#
# /etc/rc.d/init.d/supervisord
#
# Supervisor is a client/server system that
# allows its users to monitor and control a
# number of processes on UNIX-like operating
# systems.
#
# chkconfig: - 64 36
