Running PHP (wordpress) and NodeJS (Express) Apps together

We can run both the apps by configuring the virtual host files. You can find the settings i used for Apache and Nginx below. Make sure you have both of your apps ready by going over the prerequisites. In my case the wordpress blog is running in PHP while the rest of the site is running on NodeJS.

Apache

Proxy module for Apache is installed
