1.安装

宿主机环境:(Centos7)


宿主机环境

#yum install python-setuptools


yum install python-setuptools

#easy_install supervisor


easy_install supervisor

测试安装是否成功:

#echo_supervisord_conf


echo_supervisord_conf

2.创建配置文件

创建supervisor配置文件目录/etc/supervisor/

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


mkdir -m 755 -p /etc/supervisor/

创建主配文件supervisord.conf

#echo_supervisord_conf > /etc/supervisor/supervisord.conf


echo_supervisord_conf > /etc/supervisor/supervisord.conf

创建项目配置文件目录

# mkdir -m 755 conf.d


# mkdir -m 755 conf.d

3.调试

在/home/k1ic/supervisor_simple 目录下创建test.c


test.c

编译为test #gcc -o test test.c


gcc -o test test.c

在/etc/supervisor/conf.d 目录下创建 test.ini


test.ini

在主配文档中引入test.ini


files = ./conf.d/*.ini

启动supervisor

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


supervisord -c /etc/supervisor/supervisord.conf

pstree -p | grep supervisord

查看supervisord.log发现program test已启动

# cat /tmp/supervisord.log


# cat /tmp/supervisord.log

用 supervisorctl 查看已经被监控的program(注:直接用 #supervisorctl 会提示:http://localhost:9001 refused connection

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


supervisorctl -c /etc/supervisor/supervisord.conf

增加一例监控php脚本

创建skud.ini


skud.ini

[program:skuld]

在/home/k1ic/supervisor_simple目录下创建skuld.php


skuld.php

重启监控服务


reload

pstree

================分割线================

这才是重点^^

0. supervisor 比较适合监控业务应用,且只能监控前台程序,php fork方式实现的daemon不能用它监控,否则supervisor> status 会提示:BACKOFF  Exited too quickly (process log may have details)


BACKOFF  Exited too quickly (process log may have details)

cat supervisord.log

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


reload

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。

3.web管理界面

将supervisord.conf中[inet_http_server]部分做相应配置,在supervisorctl中reload即可启动web管理界面


[inet_http_server]
