一、安装
先下载最新的supervisor安装包：https://pypi.python.org/pypi/supervisor ， 如：
cd /usr/local/src
wget https://pypi.python.org/packages/7b/17/88adf8cb25f80e2bc0d18e094fcd7ab300632ea00b601cbbbb84c2419eae/supervisor-3.3.2.tar.gz
tar -zxvf supervisor-3.3.2.tar.gz
cd supervisor-3.3.2
python setup.py install #本地python版本为python2.7
# python2.7 setup.py install #本地python版本为python3以上
二、配置
1.生成配置文件
echo_supervisord_conf > /etc/supervisord.conf
2.启动
supervisord -c /etc/supervisord.conf
查看 supervisord 是否在运行：
ps aux | grep supervisord
3.配置
打开配置文件
vim /etc/supervisord.conf
在配置文件底部，配置include
[include]
files=/etc/supervisor/*.conf #若你本地无/etc/supervisor目录，请自建
用supervisor管理进程，配置如下：
cd /etc/supervisor
vim ossfs.conf # 这里的文件名称自定义
加入以下内容：
; 设置进程的名称，使用 supervisorctl 来管理进程时需要使用该进程名
[program:your_program_name]
command=python server.py --port=9000
;numprocs=1 ; 默认为1
;process_name=%(program_name)s ; 默认为 %(program_name)s，即 [program:x] 中的 x
directory=/home/python/tornado_server ; 执行 command 之前，先切换到工作目录
user=oxygen ; 使用 oxygen 用户来启动该进程
; 程序崩溃时自动重启，重启次数是有限制的，默认为3次
autorestart=true
redirect_stderr=true ; 重定向输出的日志
stdout_logfile = /var/log/supervisord/tornado_server.log
loglevel=info
这里是启动要配置的参数，请根据自己的项目自定义添加
更改了supervisor配置文件，需要重启,运行以下指令：
supervisorctl reload
4.supervisorctl的用法
supervisord : 启动supervisor
supervisorctl reload :修改完配置文件后重新启动supervisor
supervisorctl status :查看supervisor监管的进程状态
supervisorctl start 进程名 ：启动XXX进程
supervisorctl stop 进程名 ：停止XXX进程
supervisorctl stop all：停止全部进程，注：start、restart、stop都不会载入最新的配置文件。
supervisorctl 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
5.若不使用控制台来管理进程，用浏览器来管理，该如何配置？
打开配置文件
vim /etc/supervisord.conf
配置 inet_http_server
[inet_http_server]
port=127.0.0.1:9001 ; 服务器ip
username=xxx ;自定义
password=xxx ;自定义
三、设置开机启动
vim /etc/init.d/supervisord
添加以下脚本
#! /bin/sh
### BEGIN INIT INFO
# Provides: supervisord
# Required-Start: $remote_fs
# Required-Stop: $remote_fs
# Default-Start: 2 3 4 5
# Default-Stop: 0 1 6

# placed in /etc/init.d.

[ "$RETVAL" = 2 ] && return 2

# and if the daemon is only ever run from this initscript.
# If the above conditions are not satisfied then add some other code
# that waits for the process to drop all resources that could be

start-stop-daemon --stop --quiet --oknodo --retry=0/30/KILL/5 --exec $DAEMON

}
#

#

#
start-stop-daemon --stop --signal 1 --quiet --pidfile $PIDFILE --name $NAME
return 0
