Gerrit Code Review uses a replication.config file to identify the URL of the server to which changes will be replicated. For example:
[remote "host-one"] url = gerrit2@host-one.example.com:/some/path/${name}.git
A sample replication.config is installed to <gc_home>site/etc. To use this file:
cd <ac_home>/WebUI/tomcat/bin ./shutdown.sh
cd <ac_home>/WebUI/tomcat/bin ./startup.sh
