先弄懂两个命令:
supervisord : supervisor的服务器端部分，启动supervisor就是运行这个命令
supervisorctl：启动supervisor的命令行窗口。
参考：http://www.2cto.com/os/201308/238166.html
一篇文章：使用supervisor监控进程：
在linux下监控进程，可以使用inittab，最近找到了supervisor，也很好用，记录一下：
1、系统要安装python，并安装与之对应的setuptools，下载地址在此
2、安装：
# sh setuptoolsxxxx.egg
3、安装supervisor，下载地址在此，解压缩后
# python setup.py install
这就ok了，然后执行
# echo_supervisord_conf > /etc/supervisord.conf
修改/etc/supervisord.conf文件，加入你要监控的进程，里面的注释很详细，举个简单的例子：
这是一段要监控的进程的描述信息，添加到这个文件的末尾就好了：
[program:meta.txn.recover.on.error]
command=/cas/bin/meta.txn.recover.on.error ; 被监控的进程路径
numprocs=1 ; 启动几个进程
directory=/cas/bin ; 执行前要不要先cd到目录去，一般不用
autostart=true ; 随着supervisord的启动而启动
autorestart=true ; 自动重启。。当然要选上了
startretries=10 ; 启动失败时的最多重试次数
exitcodes=0 ; 正常退出代码（是说退出代码是这个时就不再重启了吗？待确定）
stopsignal=KILL ; 用来杀死进程的信号
stopwaitsecs=10 ; 发送SIGKILL前的等待时间
redirect_stderr=true ; 重定向stderr到stdout
为了节省空间，注释的内容就不贴出来了。
执行
# supervisord -n
能在控制台看到监控进程的输出：
2010-08-17 10:26:07,467 INFO supervisord started with pid 943
2010-08-17 10:26:08,469 INFO spawned: 'meta.txn.recover.on.error' with pid 1009
2010-08-17 10:26:09,876 INFO success: meta.txn.recover.on.error entered RUNNING state, process has stayed up for > than 1 seconds (startsecs)
2010-08-17 10:26:48,442 INFO exited: meta.txn.recover.on.error (terminated by SIGKILL; not expected)
2010-08-17 10:26:49,444 INFO spawned: 'meta.txn.recover.on.error' with pid 2427
2010-08-17 10:26:50,487 INFO success: meta.txn.recover.on.error entered RUNNING state, process has stayed up for > than 1 seconds (startsecs)
黑体的地方是我用kill -9杀掉进程后出来的，看到supervisor检测到进程退出后又再次启动了进程。
不带参数运行supervisord是以daemon方式运行。
把supervisord加入到开机启动项里就可以完成监控进程的功能了。
【注意】：当supervisord以非daemon方式运行时，杀掉supervisord后，被监控的进程也退出了。
而以daemon方式运行，杀掉supervisord对被监控进程无影响。
python安装：
easy_install supervisor
测试是否安装成功：
echo_supervisord_conf
会显示以下内容，其实是一个配置模版:

创建配置文件：
echo_supervisord_conf > /etc/supervisord.conf
(easy_install安装的方式好像没有/etc/supervisord.conf,所以这里我们手动创建）
修改配置文件：
在supervisord.conf最后增加(分号后边的表示注释，可以不写)：
[program:open_search]

Running supervisord automatically on startup
If you are using a distribution-packaged version of Supervisor, it should already be integrated into the service management infrastructure of your distribution.
There are user-contributed scripts for various operating systems at:https://github.com/Supervisor/initscripts
There are some answers at Serverfault in case you get stuck: How to automatically start supervisord on Linux (Ubuntu)
github的脚本下载下来：
#!/bin/bash # # supervisord This scripts turns supervisord on # # Author: Mike McGrath <mmcgrath@redhat.com> (based off yumupdatesd) # Jason Koppe <jkoppe@indeed.com> adjusted to read sysconfig, # use supervisord tools to start/stop, conditionally wait # for child processes to shutdown, and startup later # Mikhail Mingalev <mingalevme@gmail.com> Merged # redhat-init-jkoppe and redhat-sysconfig-jkoppe, and # made the script "simple customizable". # Brendan Maguire <maguire.brendan@gmail.com> Added OPTIONS to # SUPERVISORCTL status call # # chkconfig: 345 83 04 # # description: supervisor is a process control utility.

vim /etc/init.d/supervisord , 修改文件属性为可执行chmod 777 /etc/init.d/supervisordmy
加入gearman的任务，下面是百度云推送的任务
vim /etc/supervisord.conf
[program:APNS_PUSH] command=/usr/bin/php /data2/www/web/apns/worker_origin.php process_name=APNS_PUSH_%(process_num)s numprocs=2 autostart=true autorestart=true user=nginx stdout_logfile=/data2/log/push/push_%(process_num)s.log stderr_logfile=/data2/log/push/push.error.log
下面先启动gearman，启动supervisord，ps -ef |grep xxx 查看一下任务有没有执行

Supervisord是用Python实现的一款非常实用的进程管理工具，在批量服务化管理时特别有效。
1、安装
安装环境 centos python2.4
安装 wget http://pypi.python.org/packages/source/s/supervisor/supervisor-3.0a10.tar.gz#md5=99c6fbd45bade87301296b7a597fb68e
tar zxvf supervisor-3.0a10.tar.gz
cd supervisor-3.0a10
python setup.py install
如果上述遇到问题，请按如下操作。
依赖setuptools安装 wget http://pypi.python.org/packages/2.4/s/setuptools/setuptools-0.6c11-py2.4.egg#md5=bd639f9b0eac4c42497034dec2ec0c2b
sh setuptools-0.6c11-py2.4.egg
2、配置
产生基础配置文件 echo_supervisord_conf > /etc/supervisord.conf
配置 [inet_http_server]前面的分号去掉; 定义port=192.168.1.1:8888 启动 supervisord -c /etc/supervisord.conf 查看 浏览器打开 http://192.168.10.129:9001
深入配置 [program:service]
command=sh /opt/soft/service/run.sh
目前我们用supervisord 监控 memcached 进程
[program:memcached] ###定义服务
command=memcached -m 2000 -u nobody -l 0.0.0.0 -c 10240 -p 11211 ###服务运行时的显示的command
numprocs=1 ###控制memcached启动的进程数
user=root ###程序运行的用户
autostart=true ###supervisord启动memcached启动
autorestart=true ###supervisord重启memcache自动重启
stdout_logfile=/var/log/memcached.stdout.log ###监控memcached日志文件
redirect_stderr=true ###将stderr重定向到stdout（或者创建个err.log）
stopsignal=QUIT
这个程序最好不能是daemon后台守护程序。supervisord会作为这个程序的父来启动它
3、启动
supervisord (以daemon方式启动)
或 supervisord -c /etc/supervisord.conf （非daemon）
supervisord，初始启动Supervisord，启动、管理配置中设置的进程。
supervisorctl 简单的后台进程控制工具
supervisorctl stop programxxx，停止某一个进程(programxxx)，programxxx为[program:chatdemon]里配置的值
supervisorctl start programxxx，启动某个进程
supervisorctl restart programxxx，重启某个进程
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 reload，载入最新的配置文件，并按新的配置启动、管理所有进程。
supervisorctl reread，当一个服务由自动启动修改为手动启动时执行一下就ok
不带参数运行supervisord是以daemon方式运行
当supervisord以非daemon方式运行时，杀掉supervisord后，被监控的进程也退出了。
而以daemon方式运行，杀掉supervisord对被监控进程无影响
supervosrd配置文件：
command 字段设置的是后台守护应用的启动命令, 注意: 该命令必须是在前台执行的, 即会独占控制台, 否则会导致 supervisor 无法获得标准输出, 并失去进程的控制权.
