CentOS 6.3安装配置supervisor进程管理工具

1. Supervisor是一个C/S系统,它可以在类unix操作系统让用户来监视和控制后台服务进程的数量，一个很重要的功能就是监控服务器的主要后台进程，并在出现问题是自动重启。

2. 根据服务器上的python版本下载对应的setuptools

[root@test1 ~]# python -V

Python 2.6.6

wget http://pypi.python.org/packages/2.6/s/setuptools/setuptools-0.6c11-py2.6.egg#md5=bfa92100bd772d5a213eedd356d64086

直接安装

sh setuptools-0.6c11-py2.6.egg

3. 下载并安装supervisor

wget http://pypi.python.org/packages/source/s/supervisor/supervisor-3.0b1.tar.gz
tar -zxvf supervisor-3.0b1.tar.gz
cd supervisor-3.0b1
python setup.py install
安装setuptools后也可以
easy_install supervisor

4. 设定supervisor配置文件

创建默认的配置文件
echo_supervisord_conf  >/etc/supervisord.conf
vi /etc/supervisord.conf
取消以下的注释,并修改IP为0.0.0.0
[inet_http_server]        ; inet (TCP) server disabled by default
port=0.0.0.0:9001        ; (ip_address:port specifier, *:port for all iface)
username=user              ; (default is no username (open server))
password=123              ; (default is no password (open server))
增加自定义的后台进程(注意进程名之间用一个:分隔)
[program:hello]
command=python /root/hello.py
priority=1
numprocs=1
autostart=true
autorestart=true
startretries=10
stopsignal=KILL
stopwaitsecs=10
redirect_stderr=true
stdout_logfile=/root/hello.log

5. 设定supervisor启动文件

vi /etc/init.d/supervisord

#! /bin/sh

PATH=/sbin:/bin:/usr/sbin:/usr/bin

PROGNAME=supervisord

DAEMON=/usr/bin/$PROGNAME

CONFIG=/etc/$PROGNAME.conf

PIDFILE=/tmp/$PROGNAME.pid

DESC="supervisord daemon"

SCRIPTNAME=/etc/init.d/$PROGNAME

# Gracefully exit if the package has been removed.

test -x $DAEMON || exit 0

start()

{

echo -n "Starting $DESC: $PROGNAME"

$DAEMON -c $CONFIG

echo "..."

}

stop()

{

echo -n "Stopping $DESC: $PROGNAME"

supervisor_pid=$(cat $PIDFILE)

kill -15 $supervisor_pid

echo "..."

}

case "$1" in

start)

start

;;

stop)

stop

;;

restart)

stop

start

;;

*)

echo "Usage: $SCRIPTNAME {start|stop|restart}" >&2

exit 1

;;

esac

exit 0
