vi /etc/supervisord.conf

vi /etc/supervisor/conf.d/wx-prj.ini

4. Start the supervisor Service

supervisord -c /etc/supervisord.conf

When starting the service, you can track the log output and observe [[email protected] Go] # tail-F/var/log/Supervisor/supervisord. log2018-10-26 13:36:30, 881 info sorted ded extra file "/etc /. /Supervisor/CONF. d/wx-prj.ini "during parsing2018-10-26 13:36:30, 902 info RPC interface 'supervisor 'initialized2018-10-26 13:36:30, 902 crit server 'inet _ http_server' running without any HTTP Authentication checking2018-10-26 13:36:31, 203 info RPC interface 'supervisor 'initialized2018-10-26 13:36:31, 203 crit server 'unix _ http_server' running without any HTTP Authentication checking2018-10-26 13:36:31, 206 info daemonizing the supervisord process2018-10-26 13:36:31, 207 info supervisord started with PID 170402018-10-26 13:36:32, 209 info spawned: 'hello' with PID 170412018-10-26 13:36:32, 213 info spawned: 'wx-prj' with PID 170422018-10-26 13:36:32, 219 info spawned: 'World' with PID 170432018-10-26 13:36:33, 279 info success: Hello entered running state, process has stayed up for> than 1 seconds (startsecs) 13:36:33, 279 info success: WX-prj entered running state, process has stayed up for> than 1 seconds (startsecs) 13:36:33, 279 info success: World entered running state, process has stayed up for> than 1 seconds (startsecs)

You can also run the command to view the [[email protected] Conf. d] # supervisorctl statushello running PID 17041, uptime 0: 00: 19 World running PID 17043, uptime 0: 00: 19wx-prj running PID 17042, uptime 0:00:19

5. Reload the configuration modified by the supervisor

supervisorctl reload

6. Stop/start/restart programs managed by the supervisor

[[email protected] conf.d]# supervisorctl stop wx-prjwx-prj: stopped[[email protected] conf.d]# supervisorctl start wx-prjwx-prj: started[[email protected] conf.d]# supervisorctl restart wx-prjwx-prj: stoppedwx-prj: started[[email protected] conf.d]# supervisorctl stop allhello: stoppedwx-prj: stoppedworld: stopped[[email protected] conf.d]# supervisorctl start allhello: startedwx-prj: startedworld: started
