Supervisord配置使用

2019独角兽企业重金招聘Python工程师标准>>>

概要

Supervisord是用Python实现的一款非常实用的进程管理工具，类似于monit

Monit和Supervisord的一个比较大的差异是Supervisord管理的进程必须由Supervisord来启动，Monit可以管理已经在运行的程序

Supervisord还要求管理的程序是非Daemon程序，Supervisord会帮你把它转成Daemon程序，因此如果用Supervisord来管理Nginx的话，必须在Nginx的配置文件里添加一行设置Daemon off让Nginx以非Daemon方式启动

安装

• easy_install supervisor

• pip install supervisor

• 推荐前两种

• yum install epel-release -y && yum install supervisor -y

• 该方式安装版本较旧

• apt-get install supervisor -y

• dnf install supervisor -y

配置

1. easy_install及pip install安装后配置：
#查看配置文件
echo_supervisord_conf

#创建配置目录，生成配置文件
mkdir -p /etc/supervisor/
echo_supervisord_conf > /etc/supervisor/supervisord.conf

#修改supervisord.conf
echo -e '\n[include]\nfiles = /etc/supervisor/*.conf' >> /etc/supervisor/supervisord.conf

2. yum及dnf安装后配置：
/usr/bin/supervisord                    #supervisor服务守护进程
/usr/bin/supervisorctl                  #supervisor服务控制程序，比如：status/start/stop/restart pro_name等
/etc/supervisord.conf                   #supervisord配置文件，定义服务名称以及接口等
/etc/supervisord/                      #独立管理的进程配置文件目录
#修改supervisord.conf,引用/etc/supervisord/内独立配置
echo -e '\n[include]\nfiles = /etc/supervisor/*.conf' >> /etc/supervisord.conf

3. aptitude及apt-get安装后配置：
/usr/bin/supervisord                    #supervisor服务守护进程
/usr/bin/supervisorctl                  #supervisor服务控制程序，比如：status/start/stop/restart pro_name等
/etc/supervisor/supervisord.conf        #supervisord配置文件，定义服务名称以及接口等
/etc/supervisor/conf.d/                 #独立管理的进程配置文件目录
#修改supervisord.conf,引用/etc/supervisord/内独立配置
echo -e '\n[include]\nfiles = /etc/supervisor/*.conf' >> /etc/supervisor/supervisord.conf

运行

#直接运行supervisord，通用
supervisord -c /etc/supervisor/supervisord.conf

运行supervisorctl(依赖上一步)                
supervisor> help

default commands (type help <topic>):
=====================================
add    exit      open  reload  restart   start   tail   
avail  fg        pid   remove  shutdown  status  update 
clear  maintail  quit  reread  signal    stop    version

supervisorctl update         #根据最新配置文件，启动新配置或有改动的进程，配置未改动的进程不会受影响而重启
supervisorctl start/stop/restart pro_name   #启动/停止/重启某个进程
supervisorctl start/stop/restart all         #启动/停止/重启所有进程
#
supervisorctl -c /etc/supervisor/supervisord.conf status                     察看supervisor的状态
supervisorctl -c /etc/supervisor/supervisord.conf reload                     重新载入 配置文件
supervisorctl -c /etc/supervisor/supervisord.conf start [all]|[appname]      启动指定/所有 supervisor管理的程序进程
supervisorctl -c /etc/supervisor/supervisord.conf stop  [all]|[appname]      关闭指定/所有 supervisor管理的程序进程
