Master Supervisord: Install, Configure, and Manage Linux Processes Efficiently

Supervisord is a Python‑implemented process management tool that converts managed applications into daemon processes, allowing start, stop, restart, and automatic restart on crashes, ensuring self‑healing.

Note: Supervisord can only manage non‑daemon processes.

Installation

sudo easy_install supervisord

or sudo pip install supervisord or

sudo yum install supervisord

Note: The yum default repository provides Supervisord 2.x, which cannot manage child processes spawned by monitored programs, causing issues when restarting them.

Main Configuration

The primary configuration resides in the program: block of /etc/supervisord.conf; other settings (socket, log, etc.) can be adjusted as needed.

sudo vim /etc/supervisord.conf
[program:cc_refresh_inotify]
command=/usr/local/sbin/cc_refresh_inotify.sh
autostart=true
autorestart=true
stopasgroup=true
log_stdout=true
log_stderr=true
logfile=/data/losg/supervisor/cc_refresh_inotify.log

Basic Management

supervisord {start|stop|status|restart|reload|force-reload|condrestart}

supervisorctl {start|restart} programxxx – start/stop monitored program

supervisorctl reload – reload new config and restart monitored programs

supervisorctl update – restart programs whose configuration has changed
