CentOS 6.6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
# python -VPython 2.6.6wget http://pypi.python.org/packages/2.6/s/setuptools/setuptools-0.6c11-py2.6.egg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.confvi /etc/supervisord.conf取消以下的注释,并修改IP为0.0.0.0
   ; inet (TCP) server disabled by defaultport=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)
command=python /root/hello.pypriority=1numprocs=1autostart=trueautorestart=truestartretries=10stopsignal=KILLstopwaitsecs=10redirect_stderr=truestdout_logfile=/root/hello.log

5. 执行如下命令：
vi /etc/init.d/supervisord
6.输入如下内容：

注意：该文件中的如下几个变量，都需要根据你实际的目录来改写。
PREFIX=/usr/local
SUPERVISORD=$PREFIX/bin/supervisord    ##supervisord 程序的安装路径
SUPERVISORCTL=$PREFIX/bin/supervisorctl##supervisorctl 程序的安装路径
PIDFILE=/var/supervisor/supervisord.pid ##需要先创建/var/supervisor目录
LOCKFILE=/var/supervisor/supervisord.lock
OPTIONS="-c /etc/supervisord.conf" ##配置文件的路径#!/bin/bash
#
# supervisord This scripts turns supervisord on
# chkconfig:    345 83 04
# description:supervisor is a process control utility.It has a web based
#       xmlrpc interface as well as a few other nifty features.
#

# source function library

SUPERVISORCTL=$PREFIX/bin/supervisorctl

PIDFILE=/var/supervisor/supervisord.pid
LOCKFILE=/var/supervisor/supervisord.lock

OPTIONS="-c /etc/supervisord.conf"

# unset this variable if you don't care to wait for child processes to shutdown before removing the $LOCKFILE-lock
WAIT_FOR_SUBPROCESSES=yes

# remove this if you manage number of open files in some other fashion
ulimit -n 96000

RETVAL=0

running_pid()
{
# Check if a given process pid's cmdline matches a given name
pid=$1
name=$2
[ -z "$pid" ] && return 1
[ ! -d /proc/$pid ] && return 1
(cat /proc/$pid/cmdline | tr "\000" "\n"|grep -q $name) || return 1
return 0
}

running()
{
# Check if the process is running looking at /proc
# (works for all users)

# No pidfile, probably no daemon present
[ ! -f "$PIDFILE" ] && return 1
# Obtain the pid and check it against the binary name
pid=`cat $PIDFILE`
running_pid $pid $SUPERVISORD || return 1
return 0
}

start() {
echo "Starting supervisord: "

if [ -e $PIDFILE ]; then
echo "ALREADY STARTED"
return 1
fi

# start supervisord with options from sysconfig (stuff like -c)
$SUPERVISORD $OPTIONS

# show initial startup status
$SUPERVISORCTL $OPTIONS status

# only create the subsyslock if we created the PIDFILE
[ -e $PIDFILE ] && touch $LOCKFILE
}

stop() {
echo -n "Stopping supervisord: "
$SUPERVISORCTL $OPTIONS shutdown
if [ -n "$WAIT_FOR_SUBPROCESSES" ]; then
   echo "Waiting roughly 60 seconds for $PIDFILE to be removed after child processes exit"
   for sleep in2 2 2 2 4 4 4 4 8 8 8 8 last; do
   if [ ! -e $PIDFILE ] ; then
      echo "Supervisord exited as expected in under $total_sleep seconds"
      break
   else
      if [[ $sleep -eq "last" ]] ; then
         echo "Supervisord still working on shutting down. We've waited roughly 60 seconds, we'll let it do its thing from here"
         return 1
      else
         sleep $sleep
         total_sleep=$(( $total_sleep + $sleep ))
      fi

   fi
   done
fi

# always remove the subsys. We might have waited a while, but just remove it at this point.
rm -f $LOCKFILE
}

restart() {
stop
start
}

case "$1" in

echo [    DISCUZ_CODE_0    ]quot;Usage: $0 {start|stop|status|restart|reload|force-reload|condrestart}"
exit 1
esac

exit $RETVAL保存完毕之后，可以执行以下命令修改文件权限：
chmod 777 /etc/init.d/supervisord
/etc/init.d/supervisordstart
这样，supervisor就启动了。
7. 配置开机启动

执行以下命令：
chkconfig supervisordon
可以以下命令查看是否成功
chkconfig --list | grepsupervisord
