How to automatically start supervisord on Linux (Ubuntu)

Question

Supervisord does not come with an init script or does not indicate how to get it started automatically, ie. after a reboot. I've tried some user-contributed /etc/init.d scripts, but they all fail.

What would be the preferred solution ?

Answer 1

Actually, I found one that works here http://gist.github.com/176149. To install it:

sudo curl https://gist.github.com/howthebodyworks/176149/raw/88d0d68c4af22a7474ad1d011659ea2d27e35b8d/supervisord.sh > /etc/init.d/supervisord

to run it

sudo chmod +x /etc/init.d/supervisord

and to automatically schedule it, do

sudo update-rc.d supervisord defaults

Make ensure correct pid in /etc/supervisord.conf which is mapped in /etc/init.d/supervisord

example: pidfile=/var/run/supervisord.pid

Stop and Start work properly

service supervisord stop
service supervisord start

Answer 2

I created an upstart script for ubuntu 9.10

For example I installed supervisor into a virtual environment, then start and control supervisor from upstart.

create a text file /etc/init/supervisord.conf

the contents are:

description     "supervisord"

start on runlevel [345]
stop on runlevel [!345]

expect fork
respawn

exec /misc/home/bkc/Python_Environments/java2/supervisord/bin/supervisord -c /misc/home/bkc/Python_Environments/java2/supervisord/work/supervisord.conf

It will automatically start supervisor on boot. To manually start after creating the .conf file, use

sudo start supervisord

To manually stop the service, use

sudo stop supervisord

This is what I use on RHEL 5.4 and CentOS 5.5

I'm not sure wether it's depending on some configuration settings in my supervisord.conf. But it seems to work OK.

You need to run the following command after installing it

chkconfig --add supervisord

[/etc/rc.d/init.d/supervisord]

#!/bin/sh
#
# /etc/rc.d/init.d/supervisord
#
# Supervisor is a client/server system that
# allows its users to monitor and control a
# number of processes on UNIX-like operating
# systems.
#
# chkconfig: - 64 36
# description: Supervisor Server
# processname: supervisord

# Source init functions
. /etc/rc.d/init.d/functions

prog="supervisord"

prefix="/usr/"
exec_prefix="${prefix}"
prog_bin="${exec_prefix}/bin/supervisord"
PIDFILE="/var/run/$prog.pid"

start()
{
        echo -n $"Starting $prog: "
        daemon $prog_bin --pidfile $PIDFILE
        [ -f $PIDFILE ] && success $"$prog startup" || failure $"$prog startup"
        echo
}

stop()
{
        echo -n $"Shutting down $prog: "
        [ -f $PIDFILE ] && killproc $prog || success $"$prog shutdown"
        echo
}

case "$1" in

  start)
    start
  ;;

  stop)
    stop
  ;;

  status)
        status $prog
  ;;

  restart)
    stop
    start
  ;;

  *)
    echo "Usage: $0 {start|stop|restart|status}"
  ;;

esac

There is a Debian/Ubuntu script in official Supervisor GitHub repo:

Answer 5

This is working for me on Ubuntu 10.04.3 LTS. It also appears to work in 8.04:

Add the following to /etc/init.d/supervisord

#! /bin/bash -e

SUPERVISORD=/usr/local/bin/supervisord
PIDFILE=/tmp/supervisord.pid
OPTS="-c /etc/supervisord.conf"

test -x $SUPERVISORD || exit 0

. /lib/lsb/init-functions

export PATH="${PATH:+$PATH:}/usr/local/bin:/usr/sbin:/sbin"

case "$1" in
  start)
    log_begin_msg "Starting Supervisor daemon manager..."
    start-stop-daemon --start --quiet --pidfile $PIDFILE --exec $SUPERVISORD -- $OPTS || log_end_msg 1
    log_end_msg 0
    ;;
  stop)
    log_begin_msg "Stopping Supervisor daemon manager..."
    start-stop-daemon --stop --quiet --oknodo --pidfile $PIDFILE || log_end_msg 1
    log_end_msg 0
    ;;

  restart|reload|force-reload)
    log_begin_msg "Restarting Supervisor daemon manager..."
    start-stop-daemon --stop --quiet --oknodo --retry 30 --pidfile $PIDFILE
    start-stop-daemon --start --quiet --pidfile $PIDFILE --exec $SUPERVISORD -- $OPTS || log_end_msg 1
    log_end_msg 0
    ;;

  *)
    log_success_msg "Usage: /etc/init.d/supervisor
{start|stop|reload|force-reload|restart}"
    exit 1
esac

exit 0

Then run:

sudo chmod +x /etc/init.d/supervisord
sudo update-rc.d supervisord defaults

sudo service supervisord start

None of the other answers worked for me.

Answer 6

I added this lines into /etc/init.d/supervisord to fix "stop" argument processing:

do_stop()
{
    /usr/local/bin/supervisorctl stop all
    /usr/local/bin/supervisorctl shutdown
    # Return
    ...

and this works great for me.

Supervisor appears to now be in apt repository, so it shouldn't be necessary to hand-craft init files, just:

sudo apt-get install supervisor

You may want to first clean out (and backup) your old files prior to installation.
