Introduction

This article provides the procedure to configure a proxy from Apache to Tomcat.

 

Procedure

  1. Log into the server as the 'root' user via SSH or "Terminal" in WHM.
  2. Determine the AJP port from the Tomcat configuration in /home/username/ea-tomcat85/conf/server.xml. 
    [root@server ~]cPs# grep 'Connector port.*AJP' /home/username/ea-tomcat85/conf/server.xml
     <Connector port="10005" protocol="AJP/1.3" xpoweredBy="false" secretRequired="false"/>
    [root@server ~]cPs#
    This example shows that the AJP port for this domain is 10005.
  3. Create the Apache include folders for the domain. 
    mkdir -p /etc/apache2/conf.d/userdata/std/2_4/username/domain.tld
    mkdir -p /etc/apache2/conf.d/userdata/ssl/2_4/username/domain.tld
  4. Edit /etc/apache2/conf.d/userdata/std/2_4/username/domain.tld/tomcatproxypass.conf with a text editor, such as nano or vim.
  5. Add the following to /etc/apache2/conf.d/userdata/std/2_4/username/domain.tld/tomcatproxypass.conf. Be sure to replace "portnumber" with the port number found above. 
    <IfModule proxy_ajp_module>
     ProxyPass "/" "ajp://127.0.0.1:portnumber/"
    </IfModule>
  6. Save the changes and exit the text editor.
  7. Edit /etc/apache2/conf.d/userdata/ssl/2_4/username/domain.tld/tomcatproxypass.conf with a text editor, such as nano or vim. Be sure to replace "portnumber" with the port number found above. 
    <IfModule proxy_ajp_module>
     ProxyPass "/" "ajp://127.0.0.1:portnumber/"
    </IfModule>
  8. Save the changes and exit the text editor.
  9. Restart Apache. 
    /scripts/restartsrv_httpd

Please note that if you are loading a website from the domain's document root, 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. Be sure to replace "portnumber" with the port number found above.

<IfModule proxy_ajp_module>
 ProxyPass "/javaapp" "ajp://127.0.0.1:portnumber/"
</IfModule>
