Keep Ghost Running with pm2
When installing Ghost manually on a VPS or your home machine, a problem people run into is how to keep Ghost running after their terminal session has ended. pm2 allows you to keep Ghost running indefinitely and is very easy to setup and use. Here are the steps to installing
pm2 and using it with Ghost:
Note: These commands should be run from a non root user that is dedicated to running Ghost.
cd /path/to/ghost/folder sudo npm install -g pm2 echo "export NODE_ENV=production" >> ~/.profile source ~/.profile pm2 kill pm2 start index.js --name ghost pm2 dump sudo pm2 startup <centos|ubuntu|amazon>
In the last command you will need to set the start up mode based on your operating system. For example if you are running in Amazon then your command will be:
pm2 startup amazon.
Once you have Ghost up and running with
pm2 some other useful
pm2 commands are:
pm2 stop <process ID>
As you can see in the screen shot below the
pm2 statuscommand will allow you to see some useful status on your Ghost instance. Three useful things to note from the command will be the
err logscolumns. These will be very valuable.
pm2 logs command will give you live output from your Ghost blog.
pm2 monit command will give you life status on the memory footprint of Ghost.
