安装 supervisor 方法，可以直接用 yum install supervisord，但是版本可能会旧一点，可以参考官方的方法：
easy_install supervisor

http://supervisord.org/installing.html#installing-to-a-system-with-internet-access

加入 service, vim /etc/init.d/supervisord , 修改文件属性为可执行 chmod 777 /etc/init.d/supervisord

#!/bin/bash

# supervisord  This scripts turns supervisord on

exit $RETVAL

配置一下，echo_supervisord_conf > /etc/supervisord.conf

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

另外，也可以使用 gearman-monitor 来查看 gearman 任务状态
