Can a single Apache server handle both Tomcat and PHP?

Question

I have a requirement as to have a single server with both a Java application and a PHP application, running on the same Apache. Is this possible?

This question may be very silly but I have no clue about java requirements or installation procedures.

Can I do such a thing that as to have the java application running on one port and the PHP application on another port, both on the same Apache?

You can do what you want with VirtualHosts, http://httpd.apache.org/docs/2.0/vhosts/examples.html#port, but wouldn't you rather it only use one port? — cha0site, Jul 06 '12 at 14:28
That's one weird requirement right there. Perhaps they want an Apache Tomcat (for the Java app) and an Apache HTTP Server for PHP on the same server? That's certainly doable. — Gustav Barkefors, Jul 06 '12 at 14:34

Yes you can do that. Essentially you have to run the Apache (+ PHP) server on one port and the Tomcat server on a different port.

You can expose the 2nd port to the outside world, and have your URLs use either port 80 for Apache / PHP or (say) 8080 for the Java server. This simple, but you may find that upstream firewalls prevent a remote web browser from connecting to any port other than 80.
You can configure your Apache server as a reverse proxy for the Java server. So for instance, the Apache server might recognize that http://site.com/javaapp/foo.html is for the Java server, and relay requests for that URL to http://localhost:8080/javaapp/foo.html.

There is a whole chapter of the Apache documentation about configuring forward and reverse proxies using mod_proxy.

Yes.

Apache HTTPd can delegate to Apache Tomcat using ModProxy or ModAJP, and can be configured to do so based on the domain, path or file extension requested. Your Apache HTTPd configuration of PHP would remain the same.

You would need to configure Apache Tomcat to not listen on port 80, and then configure the Apache HTTPd proxying solution of your choice to talk to Tomcat on a different port.

Here's a starting point for more information: Apache + Tomcat: Using mod_proxy instead of AJP

This is possible using Apache Reverse Proxy,

I configured one Apache virtual host that serves one PHP website (Drupal) and one java (tomcat, for business logic) that are stored in the same server using a reverse proxy with 2 locations, the advantage of this configuration is that it doesn't expose the port that Tomcat is using on the URL which was mandatory for me for security reasons.

This is how I achieved this:

<VirtualHost *:80>
ProxyPreserveHost       On
DocumentRoot            "/srv/www/htdocs/"
ErrorLog                /var/log/httpd/app_error_log.log
CustomLog               /var/log/httpd/app_log.log combined
ServerName              myapp.com

#Drupal PHP Content, stored at / as the main front end website.
<Location />
    ProxyPass http://localhost/
    ProxyPassReverse http://localhost
    Order allow,deny
    Allow from all
</Location>

#Tomcat/java content, secondary site used to process payments and business logic:
<Location /javaApp>
    ProxyPass http://localhost:8080/javaApp/
    ProxyPassReverse http://localhost:8080/javaApp/
    Order allow,deny
    Allow from all
</Location>

</VirtualHost>

Restart Apache:

service httpd restart;

Test your reverse proxies: PHP/Drupal (In my case i'm using drupal but can be any PHP code):

http://yourserverip/ or http://localhost/

Java:

http://yourserverip/javaApp or http://localhost/javaApp

I hope someone can find this useful. I had a hard time trying to figure this out. :)

Regards.

Can a sinle apache server handle both tomcat and php?

Yes, you need both apache and tomcat installed, but you can configure apache to redirect (transparently for the user) all JSP requests to tomcat using AJP protocol.
