Tomcat – How to Change Port to 80 with Apache

tomcat

I have a VPS that had Apache. Later Tomcat was installed with the cPanel EasyApache thing. JSPs will work as Mysite.com/file.jsp or mysite.com:8080/file.jsp. However, JForum uses web.XML to map some servlets to URLs. Without the port 8080 in the URL, I get file not found. Is there any way to get the servlets to map on port 80 like the JSPs without killing Apache?

You can use mod_proxy for passing the data over to tomcat.

you could use something in the lines of:

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

That will proxy the data to the tomcat instance and rewrite replies so that they match the given path. I would recommend using something like nginx for plain proxying, but if you already need apache for something, it can be done with it too.

Apache – How to Set Up mod_proxy_ajp with Apache and Tomcat

You shouldn't need to make any changes to the server.xml except to put Tomcat back to the default ports so Apache can handle port 80. The bulk of the work will be done through the Apache configuration files. I typically leave these outside of the httpd.conf and instead stick them into smaller config snippets under the <ServerRoot>/conf.d/ sub-directory.

Given your example of ourserver.ourcompany.com/app1 & ourserver.ourcompany.com/app2 I would I would assume a configuration something along the following:

<VirtualHost *:80>
    ServerName ourserver.ourcompany.com
    ErrorLog ...
    CustomLog ...

    [other VHost configurations]

    ProxyPass /app1 ajp://tomcat_hostname:8009/app1
    ProxyPassReverse /app1 ajp://tomcat_hostname:8009/app1

    ProxyPass /app2 ajp://tomcat_hostname:8009/app2
    ProxyPassReverse /app2 ajp://tomcat_hostname:8009/app2
</VirtualHost>

If you have multiple Tomcat servers clustered behind then you might want to look at setting up mod_balancer and moving the ajp:// to mod_balancer BalancerMember's and replace with the balancer:// URL that refers to the balancer configuration.

Tomcat – PHP and JSP running on same machine.. Tomcat on Apache

Well, you can do it in two ways:

Using apache mod_rewrite to rewrite the URLs, it's not very easy but works
Using something in front of apache to provide a reverse proxy. nginx is a very popular option, very fast and easy do configure. Varnish is a caching reverse proxy, it's harder to configure than nginx but provides cache.

There are some examples: nginx full example, Varnish config examples, apache rewrite guide.

IMNSHO, nginx is the best choice if you will not have thousands of accesses, if this is the case, nginx + varnish can do miracles.
