安装supervisor
easy_install supervisor
echo_supervisord_conf > /etc/supervisord.conf
配置supervisor 如下
; Sample supervisor config file.
;
; For more information on the config file, please see:
; http://supervisord.org/configuration.html
;
; Notes:
; - Shell expansion ("~" or "$HOME") is not supported. Environment
; variables can be expanded using this syntax: "%(ENV_HOME)s".
; - Quotes around values are not supported, except in the case of
; the environment= options as shown below.
; - Comments must have a leading space: "a=b ;comment" not "a=b;comment".
; - Command will be truncated if it looks like a config file comment, e.g.
; "command=bash -c 'foo ; bar'" will truncate to "command=bash -c 'foo ".

supervisor 一些操作
首先启动supervisor supervisord -c /etc/supervisor/supervisord.conf
一、添加好配置文件后
二、更新新的配置到supervisord
supervisorctl update
三、重新启动配置中的所有程序
supervisorctl reload
四、启动某个进程(program_name=你配置中写的程序名称)
supervisorctl start program_name
五、查看正在守候的进程
supervisorctl
六、停止某一进程 (program_name=你配置中写的程序名称)
pervisorctl stop program_name
七、重启某一进程 (program_name=你配置中写的程序名称)
supervisorctl restart program_name
八、停止全部进程
supervisorctl stop all
注意：显示用stop停止掉的进程，用reload或者update都不会自动重启。
