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, JBoss EWS, or the EAP 6 Apache Web Server
- There may be specific combinations of products that require specific products versions or combinations, such as mod_cluster
- 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_proxy is generally available/builtin with each Apache related product we ship
- For EAP 5, mod_cluster is currently only shipped with the EWS + EAP and is supported on RHEL 6's Apache
- The issue with prior versions of RHEL is Apache 2.2.8+ was not provided and mod_cluster does not work on httpd versions less than 2.2.8
- mod_cluster will be tested and supported on the httpd version in RHEL6+
- mod_jk is supported on the EWS + EAP and in RHEL 6
An EAP entitlement is needed to receive support for the use of mod_jk on RHEL 6 in addition to the RHEL entitlements
- mod_jk does not ship with RHEL and requires the bits shipped in the EAP natives download or require that you get the mod_jk package from the EAP channel in RHN
An Apache HTTPD bundle (equivalent to EWS's httpd offering and tested and supported for loadbalancing EAP 6 servers through mod_proxy/jk/cluster) is now included as a separate download with JBoss EAP 6
- Support of this EAP 6 Apache server is covered by existing EAP entitlements
- There are a few differences about supported configuration between EAP 4, 5, and 6
- 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.
|EAP 4||EAP 5||EAP 6|
|RHEL 5's 2.2.3||mod_proxy||mod_proxy||mod_proxy+mod_jk|
|RHEL 6's 2.2.15||mod_proxy||mod_proxy+mod_jk+mod_cluster||mod_proxy+mod_jk+mod_cluster|
|EAP 6 HTTP Server||N/A||mod_proxy+mod_jk+mod_cluster||mod_proxy+mod_jk+mod_cluster|
