How to Install Supervisord on CentOS 7

Supervisor is a program used to monitor and control programs. It can auto startup application on server boot time, and restart if the application fails.

To install supervisors on CentOS 7, first, enable epel repository.

yum install -y epel-release

Once EPEL repository is enabled, you can install supervisors with the yum command

yum install -y supervisor

Enable supervisord to start on boot, run

systemctl enable supervisord

Start supervisord

systemctl start supervisord

To start a python application on boot time, I created file

vi /etc/supervisord.d/telegram-bot.ini

With the following content

[program:telegram_bot]
command=/root/bots/telegram_bot/bot.py
directory=/root/bots/telegram_bot
;process_name=%(program_name)s ; process_name expr (default %(program_name)s)
numprocs=1
autostart=true
autorestart=true
stdout_logfile=/var/log/telegram-bot.log
stdout_logfile_maxbytes=1MB
stdout_logfile_backups=10
stdout_capture_maxbytes=1MB
stdout_events_enabled=false
stderr_logfile=/var/log/telegram-bot-error.log
stderr_logfile_maxbytes=1MB
stderr_logfile_backups=10
stderr_capture_maxbytes=1MB
stderr_events_enabled=false

Started application with

supervisorctl reload
