Created page with "There are several apps/scripts, running on our main Lab server (spitfire.initlab.org). They run as user '''apps'''. To access them, login as root, and use the following comma..."

New page

There are several apps/scripts, running on our main Lab server (spitfire.initlab.org). They run as user '''apps'''.

To access them, login as root, and use the following command:

'''sudo -iu apps'''

== Status monitoring and management ==

You can see the running apps using:

'''pm2 list'''

or see a log browser and live metrics using:

'''pm2 monit'''

These apps restart automatically on crash. In order to stop any of them, note its number in '''pm2 list''', and issue the command:

'''pm2 stop 23''' (where 23 is the ID of the app)

Then to start:

'''pm2 start 23'''

More info about PM2: https://pm2.keymetrics.io/docs/usage/quick-start/

If you want to check or manage the status the whole process manager (pm2), please use the systemd unit '''pm2-apps.service''' as root. It is responsible for starting the process manager and all apps on system boot.

'''systemctl start pm2-apps'''

'''systemctl stop pm2-apps'''

'''systemctl restart pm2-apps'''

'''systemctl status pm2-apps'''

== Add a new app ==

As user '''apps''':

*'''git clone URL-OF-APP'''

*'''cd DIR-OF-APP'''

*'''npm install'''

* create/adjust the app config, if necessary

*'''cd ..'''

* edit '''ecosystem.config.js''', be careful about trailing commas

*'''pm2 reload ecosystem.config.js''' (this will start the new app, if properly added and configured)

*'''pm2 save''' (this will add the app to startup list)
