Loadbalancing + clustering Tomcat 6Hello,
Ok, we are testing Liferay portal and in order to provide a proof of concept i need to make it as close as possible as what the production environment would be.
I am separating everything into different servers, my plan is to have: - 2 Apache load balancers (apache +mod_jk and clustered?) - 2 Tomcat servers (clustered) - 2 MySQL servers (clustered)
The only one i am having question about is the load balancing section as the other 2 are pretty much straight forward.
- Load Balancers: Apache + mod_jk I can set them up individually without any problems, but how can i make them redundant? DNS round robin? another cluster? or does the mod supports HA via config params? I can only see this as a hot-standby unless there is a hot-hot way of getting this working???
See i dont want the load balancing part to be the single point of failure.
Any ideas? Thanks. |
