How to proxy from Apache to Tomcat

Introduction

How do I proxy from Apache to Tomcat

Procedure

First, you need to determine the AJP port from the Tomcat configuration in /home/$USER/ea-tomcat85/conf/server.xml:

# grep 'Connector port.*AJP' /home/$USER/ea-tomcat85/conf/server.xml
 <Connector port="10005" protocol="AJP/1.3" xpoweredBy="false" secretRequired="false"/>

This shows that the AJP port for this domain is going to be 10005.

Once you know the port you can create the include files for the domain: You will need to make sure the parent directories are created before creating the file.

/etc/apache2/conf.d/userdata/std/2_4/$username/$domain.tld/tomcatproxypass.conf:

<IfModule proxy_ajp_module>
 ProxyPass "/" "ajp://127.0.0.1:$PORT/"
</IfModule>

/etc/apache2/conf.d/userdata/ssl/2_4/$username/$domain.tld/tomcatproxypass.conf:

<IfModule proxy_ajp_module>
 ProxyPass "/" "ajp://127.0.0.1:$PORT/"
</IfModule>

Note:

If you are loading a website from the document root of the domain you may need to use another path for the ProxyPass statement other than /, for instance, if you want your Tomcat application to load from /javaapp you will add the following statement to the Apache include:

<IfModule proxy_ajp_module>
 ProxyPass "/javaapp" "ajp://127.0.0.1:$PORT/"
</IfModule>

After you create the proxies you will need to restart Apache:

/scripts/restartsrv_httpd
