定义

  1. Supervisor 是一个 C/S 模型的程序，supervisord 是 server 端，supervisorctl 的shell、和网页端 是 client 端

安装

  1. apt-get install supervisor
  2. yum install supervisor

查看服务

  1.  systemctl status  supervisord
  2.     ○ supervisord.service - Process Monitoring and Control Daemon
  3.      Loaded: loaded (/usr/lib/systemd/system/supervisord.service; disabled; vendor preset: disabled)
  4.      Active: inactive (dead)
  5.        Docs: http://supervisord.org

配置

配置文件

  1. 配置文件 /etc/supervisord.conf
  2. 配置文件夹 /etc/supervisor.d

子进程配置

子进程配置文件路径 /etc/supervisor.d
新建文件programe.ini
输入以下内容

  1. [program:father]
  2. directory=/run/media/duxin/G/work_space/python_project/process
  3. command=python father.py
  4. autorestart=true
  5. autostart=true
  6. redirect_stderr=true
  7. user=duxin
  8. stdout_logfile_maxbytes=50MB
  9. stdout_logfile_backups=5
  10. stdout_capture_maxbytes=1MB
  11. stdout_events_enabled=false
  12. loglevel=warn

一个进程就配置好了
另一个多组子进程的配置例子

  1. [program:food_crm]
  2. directory=/run/media/duxin/G/eartip/code_test/FoodCrm
  3. command=/home/duxin/.local/share/virtualenvs/FoodCrm-28Lm7e7d/bin/python manage.py runserver 0:99%(process_num)02d
  4. process_name=%(program_name)s_%(process_num)02d 
  5. numprocs=4
  6. autorestart=true
  7. autostart=true
  9. stopasgroup=true
  10. killasgroup=true
  12. redirect_stderr=true
  13. user=duxin
  14. stdout_logfile_maxbytes=50MB
  15. stdout_logfile_backups=5
  16. stdout_capture_maxbytes=1MB
  17. stdout_events_enabled=false
  18. loglevel=warn

可以看到多了process_name、numprocs两个参数
stopasgroup、killasgroup 保证启停的时候把带着子进程一起起停

添加 web 支持

在/etc/supervisord.conf配置文件中将下面几行前面的分号去掉，修改一下数据保存退出（用户名与密码自己定义）

  1. [inet_http_server]             # inet (TCP) server disabled by default
  2. port=0.0.0.0:9001              # ip_address:port specifier, *:port for all iface
  3. username=user                  # default is no username (open server)
  4. password=123                   # default is no password (open server)

重启
systemctl trstart supervisord
效果
http://localhost:9001/

supervisorctl命令

输入命令 supervisorctl 进入 supervisorctl 的 shell 交互界面

也可以不进入supervisorctl的shell，直接在终端执行命令操作：
supervisorctl status
supervisorctl update
