Setup Apache2 for Tomcat

How can I setup Apache2 to access my Spring REST API hosted on Tomcat 8? Is this okay? It doesn't seem to be working.

I was following this tutorial https://medium.com/@mirela95/apache-http-server-as-reverse-proxy-with-java-back-end-application-running-on-tomcat-9c8c9210783e

Here is my configuration file. It is stored under sites-available

<VirtualHost *:80>
   ProxyPreserveHost On
   ProxyPass /springrest http://127.0.0.1:8932/
   ProxyPassReverse /springrest http://127.0.0.1:8932/
</VirtualHost>
Solution

  • If that is your entire config file then you don't have enough. You must have the ServerName parameter to have things work correctly. You'll need to use:

    <VirtualHost *:80>
    ServerName www.example.com
    ServerAlias example.com

    ProxyPreserveHost on
    ProxyPass /springrest http://localhost:8932/
    ProxyPassReverse /springrest http://127.0.0.1:8932/
    ProxyTimeout 360
</VirtualHost>

    This file is normally named something like www.example.com.conf. Once you put it into sites-available you'll need to run sudo a2ensite www.example.com and then sudo systemctl restart apache2.
