centos 下Supervisor 守护进程基本配置

Posted 2020-08-05 漂泊雪狼的博客

supervisor:C/S架构的进程控制系统，可使用户在类UNIX系统中监控、管理进程。常用于管理与某个用户或项目相关的进程。

组成部分
supervisord：服务守护进程
supervisorctl：命令行客户端
Web Server：提供与supervisorctl功能相当的WEB操作界面
XML-RPC Interface：XML-RPC接口

 

安装

easy_install supervisor

创建默认的配置文件

echo_supervisord_conf >/etc/supervisord.conf
vi /etc/supervisord.conf

 

修改配置文件如下，这个例子设置了一个nginx和asp.net core的守护进程

  6 ; Notes:
  7 ;  - Shell expansion ("~" or "$HOME") is not supported.  Environment
  8 ;    variables can be expanded using this syntax: "%(ENV_HOME)s".
  9 ;  - Comments must have a leading space: "a=b ;comment" not "a=b;comment".

启动Supervisor

supervisord -c /etc/supervisord.conf

浏览器中输入http://127.0.0.1:8888，输入用户名密码，就可以看到后台进程列表
