一、安装配置supervisor

1.安装python自动化工具    #yum install python-setuptools

2.#easy_install supervisor安装supervisor

3.测试安装是否成功 #echo_supervisord_conf

4.创建配置文件:

(1)创建supervisor配置文件目录/etc/supervisor/  

#mkdir -m 755 -p /etc/supervisor/

(2)创建主配文件supervisord.conf

#echo_supervisord_conf > /etc/supervisor/supervisord.conf

(3)创建项目配置文件目录

# mkdir -m 755 conf.d

5.在配置文件目录中添加测试配置文件 
如:convert.ini

技术分享

然后在主配置文件supervisord.conf的最下面添加

[include]

file = ./conf.d/convert.ini

6.启动supervisor---手动启动

# supervisord -c /etc/supervisor/supervisord.conf

pstree -p | grep supervisord

查看supervisord.log发现program convert已启动

# cat /tmp/supervisord.log

7.#supervisorctl -c /etc/supervisor/supervisord.conf  进入到supervisor管理

status 查看状态

stop all停止

reload重启监控服务

注意:

(1)每次修改配置文件后需进入supervisorctl,执行reload, 改动部分才能生效

(2)两个命令

supervisord : supervisor的服务器端部分,用于supervisor启动

supervisorctl:启动supervisor的命令行窗口,在该命令行中可执行start、stop、status、reload等操作。

 

二、supervisord启动脚本

1.执行如下命令:

vim /etc/init.d/supervisord

2.输入如下内容:

#!/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
. /etc/rc.d/init.d/functions

set -a

PREFIX=/usr

SUPERVISORD=$PREFIX/bin/supervisord
SUPERVISORCTL=$PREFIX/bin/supervisorctl

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

OPTIONS="-c /etc/supervisor/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 in  2 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 "$1" in
  start)
    start
    RETVAL=$?
    ;;
  stop)
    stop
    RETVAL=$?
    ;;
  restart|force-reload)
    restart
    RETVAL=$?
    ;;
  reload)
    $SUPERVISORCTL $OPTIONS reload
    RETVAL=$?
    ;;
  condrestart)
    [ -f $LOCKFILE ] && restart
    RETVAL=$?
    ;;
  status)
    $SUPERVISORCTL $OPTIONS status
    if running ; then
      RETVAL=0
    else
      RETVAL=1
    fi
    ;;
  *)
    echo $"Usage: $0 {start|stop|status|restart|reload|force-reload|condrestart}"
    exit 1
esac

exit $RETVAL

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

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/supervisor/supervisord.conf"   ##配置文件的路径

 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/supervisord  start
或
service supervisord start

 这样supervisor就启动了

3. 配置开机启动

执行以下命令:

chkconfig supervisord  on

可以以下命令查看是否成功

chkconfig --list | grep  supervisord
