install
在Python项目里可以pip安装:
pip install supervisor
run supervisord
可以指定配置文件来启动:
supervisord -c ./supervisord.conf
配置模板文件可以用echo_supervisord_conf > supervisord.conf来生成, 然后修改
配置文件里可以配置program和group
[program:surge-backend]
command=gunicorn main:app ; the program (relative uses PATH, can take args)
autostart=true ; start at supervisord start (default: true)
autorestart=true ; when to restart if exited after running (def: unexpected)
stdout_logfile=/tmp/surge/logs/supervisor.out.log ; stdout log path, NONE for none; default AUTO
stderr_logfile=/tmp/surge/logs/supervisor.err.log ; stderr log path, NONE for none; default AUTO
[program:websocket]
command=python websocket_server.py ; the program (relative uses PATH, can take args)
autostart=true ; start at supervisord start (default: true)
autorestart=true ; when to restart if exited after running (def: unexpected)
stopasgroup=true ; send stop signal to the UNIX process group (default false)
killasgroup=true ; SIGKILL the UNIX process group (def false)
stdout_logfile=/tmp/surge/logs/websocket.out.log ; stdout log path, NONE for none; default AUTO
stderr_logfile=/tmp/surge/logs/websocket.err.log ; stderr log path, NONE for none; default AUTO
[group:surge]
programs=surge-backend,websocket ; each refers to 'x' in [program:x] definitions
run supervisorctl
配置好之后就可以用supervisorctl来管理
supervisorctl start surge:websocket
supervisorctl stop surge:websocket
supervisorctl start surge:*
supervisorctl restart surge:*
supervisorctl stop surge:*
其他问题
如果一台服务器上要启动多个supervisord, 那么各个supervisord的配置文件需要配置不一样的file和pidfile.
