NodeJS with Supervisord

Below is a quick run of configuring NodeJS with Supervisord.

Here is the base config for supervisord.conf on Gentoo:


file=/var/run//supervisor.sock   ; (the path to the socket file)  
chmod=0700                       ; sockef file mode (default 0700)

serverurl=unix:///var/run//supervisor.sock ; use a unix:// URL  for a unix socket

supervisor.rpcinterface_factory = supervisor.rpcinterface:make_main_rpcinterface

files = /etc/supervisor/conf.d/*.conf  

The per-application configuration files are held in /etc/supervisor/conf.d/*.conf per the [include] block at the bottom of /etc/supervisord.conf.

Here is a per-application configuration file of Ghost CMS (which this blog is using!):

command = node /path/to/ghost/index.js  
directory = /path/to/ghost  
user = myuser  
autostart = true  
autorestart = true  
stdout_logfile = /var/log/supervisord/ghost.log  
stderr_logfile = /var/log/supervisord/ghost_err.log  
environment = NODE_ENV="production"  

Make sure to replace the command, directory and user values with appropriate values for your environment. The rest of the values are also configurable.

Once you have configured the per-application file you can start supervisord:

/etc/init.d/supervisord start

If you already have supervisord started, you can run the following to start the ghost process;

supervisorctl start ghost  

Congratulations, you have supervisord controlling NodeJS!

I will be doing another post soon on setting up NodeJS with pm2 for better process management, control and performance.
