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

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.

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.

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=/usrSUPERVISORD=$PREFIX/bin/supervisord      ##supervisord   程序的安装路径SUPERVISORCTL=$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.lockOPTIONS="-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
