Gerrit supports automatic site initialization on server startup when Gerrit runs in a servlet container. Both creation of a new site and upgrade of an existing site are supported. By default, all packaged plugins will be installed when Gerrit is deployed in a servlet container and the location of the Gerrit distribution can be determined at runtime. It is also possible to install only a subset of packaged plugins or not install any plugins.
This feature may be useful for such setups where Gerrit administrators don’t have direct access to the database and the file system of the server where Gerrit should be deployed and, therefore, cannot perform the init from their local machine prior to deploying Gerrit on such a server. It may also make deployment and testing in a local servlet container faster to set up as the init step could be skipped.
The site initialization will be performed only if the
system property exists. The value of the property is not used; only the
existence of the property matters.
gerrit.site_path system property is defined then the init is
run for that site. The database connectivity, in that case, is defined
gerrit.site_path is not defined then Gerrit will try to find the
gerrit.init_path system property. If defined this property will be
used to determine the site path. The database connectivity, also for
this case, is defined by the
jdbc/ReviewDb JNDI property.
jdbc/ReviewDbJNDI property for an H2 database under the path defined by either
gerrit.init_pathwill cause an incomplete auto initialization and Gerrit will fail to start. Opening a connection to such a database will create a subfolder under the site path folder (in order to create the H2 database) and Gerrit will no longer consider that site path to be new and, because of that, skip some required initialization steps (for example, Lucene index creation). In order to auto initialize Gerrit with an embedded H2 database use the
gerrit.site_pathto define the location of the review site and don’t define a JNDI resource with a URL under that path.
gerrit.install_plugins property is not defined then all
packaged plugins will be installed. If it is defined then it is parsed
as a comma-separated list of plugin names to install. If the value is an
empty string then no plugin will be installed.
Prepare Tomcat so that a site is initialized at a given path using the
H2 database (if the site doesn’t exist yet) or using whatever database
is defined in
etc/gerrit.config of that
$ export CATALINA_OPTS='-Dgerrit.init -Dgerrit.site_path=/path/to/site' $ catalina.sh start
Assuming the database schema doesn’t exist in the database defined via
jdbc/ReviewDb JNDI property, initialize a new site using that
database and a given
$ export CATALINA_OPTS='-Dgerrit.init -Dgerrit.init_path=/path/to/site' $ catalina.sh start
