== Changing Ports in Gyrex ==

While the jetty ports for the provided applications can easily be configured in the Gyrex admin UI, there are some more ports, which are involved in a Gyrex runtime environment

=== Gyrex Admin UI port ===

The http port for the gyrex admin ui can be configured with the system/startup property
gyrex.admin.http.port
Without this setting the default port is 3110

=== Zookeeper port ===

The port for  the embedded ZooKeeper can be configured with the system/startup property
gyrex.zookeeper.port
Without this setting the default port is 2181

=== Configuring a port offset ===
There are additional ports in a gyrex runtime environment for jmx connection and ssh console connection.
In a development environment there is often the need to run several gyrex instances on one machine. To avoid port conflicts, gyrex provides a port offset property, which offsets (all) ports by the given offset
The name of this property is gyrex.portOffset 
The ports effected by this offset are
- admin ui port
- zookeeper port
- jmx port
- ssh port
- the default http port of jetty

Please note: the offset is only applied on a given port, if it still uses the default setting, e.g. if gyrex.zookeeper.port is set, then the offset property has no additional effect on the zookeeper port
