Redirect apache to tomcat using mod_proxy

Whenever i configure a new server i usually end up searching for this problem. How to redirect apache to tomcat ? There are various solutions out there but for now i am going to talk to about the easy one. Here are the steps :

Assumption : It is assumed that you have ssh access to your server and JDK, Tomcat and apache have been successfully installed.

Step 1 : Enable module proxy

ubuntu@ip-172-31-23-106:~$ sudo a2enmod proxy
Enabling module proxy.
To activate the new configuration, you need to run:
  service apache2 restart

Step 2 : Enable module proxy_http

ubuntu@ip-172-31-23-106:~$ sudo a2enmod proxy_http
Considering dependency proxy for proxy_http:
Module proxy already enabled
Enabling module proxy_http.
To activate the new configuration, you need to run:
  service apache2 restart

Step 3 : Restart apache

ubuntu@ip-172-31-23-106:~$ sudo  service apache2 restart
 * Restarting web server apache2

Step 4 : Edit VirtualHost

ubuntu@ip-172-31-23-106:~$ cd /etc/apache2/
ubuntu@ip-172-31-23-106:/etc/apache2~$ sudo vi sites-enabled/000-default.conf

Step 5 : Add Proxy entry inside VirtualHost tag

        ServerName YOURSERVERNAMEGOESHERE

        ProxyRequests Off
        ProxyPreserveHost On

        <Proxy *>
                Order deny,allow
                Allow from all
        </Proxy>

        ProxyPass / http://localhost:8080/
        ProxyPassReverse / http://localhost:8080/

Step 6 : Save file and restart apache

Now if you try to access your website on port 80 it won’t show you apache page but it will show you tomcat default page.
