1 2 3 4 |
# 以下三个选一个 pip install supervisor easy_install supervisor apt-get install supervisor |
生成默认配置文件
生成默认配置文件的方法如下：
|
1 |
echo_supervisord_conf > /etc/supervisord.conf |
配置文件常用配置如下：

启动Supervisor
通过如下命令使用上述配置文件启动Supervisor：
|
1 |
supervisord -c /etc/supervisord.conf |
管理Supervisor中的进程
通过supervisorctl可以对Supervisor启动的进程进行管理，首先使用下面的命令打开Supervisor的控制台：
|
1 |
supervisorctl -c /etc/supervisord.conf |
相关命令如下：
|
1 2 3 4 5 6 7 8 9 |
status ;查看supervisor中的进程状态 stop programxxx ;停止programxxx进程 start programxxx ;启动programxxx进程 restart programxxx ;重启programxxx进程 stop all ;停止全部进程 start all ;开始全部进程 restart all ;重启全部进程 reload ;载入最新的配置文件，停止原有进程并按新的配置启动、管理所有进程 update ;根据最新的配置文件，启动新配置或有改动的进程，配置没有改动的进程不会受影响而重启 |
注：programxxx为[program:theprogramname]里配置的值。
另外，通过Web端也可以进行管理，地址及认证信息详见[inet_http_server]中的配置。
