Supervisord Trouble Shooting on CentOS7

Supervisord Trouble Shooting on CentOS7

Recently, my colleague enlarge the memory of our cloud machine, after that, supervisord is not running.
Event I re-install that, it can not start. No error, no exception, nothing useful from logging.

Finally, I checked the systemctl configuration, I found the file is empty now. So I try to fix that.

> sudo vi /usr/lib/systemd/system/supervisord.service

> cat /usr/lib/systemd/system/supervisord.service
[Unit]                                                             
Description=supervisord - Supervisor process control system for UNIX
Documentation=http://supervisord.org                               
After=network.target                                               
[Service]                                                          
Type=forking                                                       
ExecStart=/usr/bin/supervisord -c /etc/supervisord.conf            
ExecReload=/usr/bin/supervisorctl reload                           
ExecStop=/usr/bin/supervisorctl shutdown                           
User=root
[Install]                                                          
WantedBy=multi-user.target

> systemctl enable supervisord

> systemctl start supervisord

> systemctl status supervisord

It is working fine after that.
