    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.

    http://supervisord.org

    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
