Resolution
-
Red Hat does not provide support for third-party hardware load balancers
- If you have queries on third party load balancers, we recommend contacting the hardware vendor
-
In regards to what is supported for each product please see the resources section and the associated links for each url below:
-
We only officially support running the Apache httpd version shipped with RHEL or JBoss Core Services (JBCS). Prior httpd distributions through JBoss EWS or JWS or the EAP 6 Apache Web Server are now retired and end of life.
- Note that using custom builds of Apache httpd or the community versions of Apache httpd is out of our support scope and we do not provide any support for such Apache httpd.
-
You can use Red Hat's load balancer configuration app to generate an optimize configuration for mod_jk, mod_proxy, or mod_cluster.
A few notes pertaining to mod_* support:
- mod_proxy is generally available/builtin with each Apache related product we ship
- mod_jk and mod_cluster are only provided and supported within JBCS, which is only currently supported on RHEL 7 and 8.
- A JBCS httpd zip distribution for RHEL 9 is forthcoming
- In RHEL 9,
mod_jkandmod_proxy_clusterhave been added as RHEL packages. See RHEL9 release note for details.
- httpd, mod_jk, and mod_cluster were previously included under JWS 3.0 and earlier, but this is now retired and end of life
- An Apache HTTPD bundle (equivalent to JWS's httpd offering and tested and supported for loadbalancing EAP 6 servers through mod_proxy/jk/cluster) was included as a separate download with JBoss EAP 6 but is now end of life.
- You can see the supported configurations of each version at following urls:
You can refer to the table below for a reference of what Apache httpd loadbalancer modules are supported for a given EAP and httpd combination.

| RHEL7's 2.4.6 | mod_proxy | mod_proxy | mod_proxy | mod_proxy |
| RHSCL's httpd | mod_proxy | mod_proxy | mod_proxy | mod_proxy |
| EWS/JWS | Use JBCS instead | Use JBCS instead | Use JBCS instead | Use JBCS instead |
