1、檢視python版本

[[email protected] ~]# python -V

Python 2.6.6

2、下載並安裝supervisor
wget http://pypi.python.org/packages/source/s/supervisor/supervisor-3.0b1.tar.gz --no-check-certificate
tar -zxvf supervisor-3.0b1.tar.gz
cd supervisor-3.0b1
python setup.py install

最後顯示：
Using /usr/lib/python2.6/site-packages
Finished processing dependencies for supervisor==3.0b1
表示成功

[
yum install python-setuptools
安裝setuptools後也可以easy_install supervisor
]

3、 設定supervisor配置檔案

touch /var/log/supervisord.log
chmod 777 /var/log/supervisord.log

建立預設的配置檔案
echo_supervisord_conf  >/etc/supervisord.conf

chown www:www /etc/supervisord.conf
chmod 744 /etc/supervisord.conf

修改配置檔案
vi /etc/supervisord.conf

; Sample supervisor config file.
;
; For more information on the config file, please see:
; http://supervisord.org/configuration.html

;[group:thegroupname]
;programs=progname1,progname2  ; each refers to 'x' in [program:x] definitions
;priority=999                  ; the relative start priority (default 999)

; The [include] section can just contain the "files" setting.  This
; setting can list multiple files (separated by whitespace or
; newlines).  It can also contain wildcards.  The filenames are
; interpreted as relative to this file.  Included files *cannot*
; include files themselves.

[include]
files = /etc/supervisor/*.ini

--------------------------------------------------------------------
增加自定義的後臺程序(注意程序名之間用一個:分隔)

mkdir /etc/supervisor/
chown www:www -R /etc/supervisor/

---------------------

例子1：

vi /etc/supervisor/server.ini

[program:server]
command=python /opt/archive_server/server.py
autorstart=true
redirect_stderr=true
stdout_logfile=/mnt/log/supervisord_server.log
directory=/tmp
user=root
priority=1

---------------------------------------

4、啟動指令碼（高大上些）

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 "..."
}

status()
{
        ps -ef|grep supervisord
}

case "$1" in
  start)
        start
        ;;
  stop)
        stop
        ;;
  status)
        status
        ;;
  restart)
        stop
        start
        ;;
  *)
        echo "Usage: $SCRIPTNAME {start|stop|restart|status}" >&2
        exit 1
        ;;
esac
exit 0

-----------------------------------------------

chmod a+x /etc/init.d/supervisord

-------------------------------------------------------
/etc/init.d/supervisord start
/etc/init.d/supervisord stop
/etc/init.d/supervisord restart

[[email protected] supervisor-3.0b1]$ ps -ef|grep supervisord
www      30335     1  0 17:23 ?        00:00:00 /usr/bin/python /usr/bin/supervisord -c /etc/supervisord.conf
www      31986 27782  0 17:24 pts/1    00:00:00 grep supervisord

---------------------------------------------

5、開機啟動
vi /etc/rc.d/rc.local
su www -c "/etc/init.d/supervisord start"

su www -c "/usr/bin/supervisorctl start all"
--------------------------------------

例子2：
在 /etc/supervisor/ 目錄下建立 redis.ini 檔案

[program:redis]
command=/usr/bin/redis-server /usr/local/redis/redis.conf
autorstart=true
autorestart=true
stdout_logfile=/tmp/supervisor.log
