UsingMod_proxy With Apache2 and Tomcat

1. yum install apache2
2. Setup Apache to use mod_proxy (AJP)
Make sure that at least following modules are loaded (uncomment this in httpd.conf)

LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_balancer_module modules/mod_proxy_balancer.so
LoadModule proxy_ajp_module modules/mod_proxy_ajp.so

Add those lines in /etc/httpd/conf/httpd.conf :

<Proxy balancer://mycluster>
    Order deny,allow
   Allow from all
   BalancerMember ajp://localhost:8009/yourapp
</Proxy>
 
<VirtualHost *:80>
   ServerAdmin admin@yourhost.com
   ServerName  www.yourhost.com
   ServerAlias  yourhost.com

   ProxyPass /yourapp balancer://mycluster
   ProxyPassReverse /yourapp balancer://mycluster/

   ErrorLog logs/yourhost_error_log
   CustomLog logs/yourhost_access_log combined
</VirtualHost>

3. The yourapp application will be deployed in tomcat, and make sure the tomcat 8009 connector is opened.

4. In a browser, type: http://www.yourhost.com/yourapp, it will go to yourapp that deployed in the tomcat, you don't need to type the port number.
