This is a basic Resin configuration with two servers in a single cluster.
Since this configuration does not have a load balance tier, it needs a load balancer
(Resin, Apache or hardware) to work properly.
- The two servers act as backups for each other for clustering purposes, because they form
the first two clusters of a triad. The two servers check each others heartbeats, record statistics and save each others statistics and error logs.
- Each server listens to HTTP port 8080 and serves web-apps from the webapps directory.
The root web-app would be in webapps/ROOT, for example. Standard servlet behavior and jsp and php support is enabled with the <resin:import> of app-default.xml.
- JDK logging goes to stdout, which goes to jvm-a.log and jvm-b.log as managed by
the watchdog.
- Proxy caching is enabled to improve performance.
- The /resin-admin is enabled
