overview
1. Restart the supervisor service
Premise: Monitor and alarm and find that the supervisor service is down or check the service and find that the supervisor service is down
Execute the sudo supervisorctl command, and after entering the password, it is found that the execution fails, indicating that the supervisor service is down
Solution:
1. First find the directory where the supervisor is installed, the command is
whereis supervisor1
2. Find the corresponding supervisor configuration file path, see screenshot
3. Start the supervisor service, the command is
sudo supervisord -c /etc/supervisor/supervisord.conf1
4. To check whether the supervisor service is running normally, the command is
sudo supervisorctl1
If it still doesn’t work, repeat steps 3 and 4.
To close the supervisor, execute the command
sudo supervisorctl shutdown1
see screenshot
To restart the supervisor, execute the command
sudo supervisorctl reload1
See the screenshot (the premise of restarting is that the supervisor is already starting)
