The Apache Tomat Connector module (mod_jk) is not currently in included Centos or EPEL repositories.

To assist in the deployment and management of the Apache mod_jk module a RPM package will be created from the built source using FPM. If you havn’t stumbled upon or used FPM I highly recommend taking a look.

The basic overview of the process is as follows:

1. Obtain/Download the lastest release source
2. Verify you have the prerequisites installed for building the module
3. Build the latest release
4. Create FPM build root
   • Create configuration file directory structure (httpd.conf)
   • Create module directory structure
   • Create mod_jk.conf configuration file
   • Copy mod_jk.so into module directory structure
5. Generate RPM package using FPM

Here is a more detailed article on the exact process listed above.
