I recently setup a server to run multiple instance of IBM HTTP Server from a Single IHS Install.
Originally the servers looked like this,
IHS mod_jk connection to Apache Tomcat using context root /my-app/ using SSL certificate https://test1.acme.com/
The customer wanted to leverage the existing system to create a secondary test environment.
Virtual hosting was not an option, because the team was willing to change the domain name, but not the context root. Also, the customer was able to provide a second IP for the server.
Instructions
The instructions are well documented on the IBM Website Article Running multiple instances of IBM HTTP Server from a single install and outlines two approaches.
Recorded here is the abridged version with the added assurance that the chosen approach worked and has been running fine over the last year.
