How to install Gerrit

1. Install java jdk or Oracle java if you do not have it already

apt install openjdk-8-jre-headless

2. Create directories named review

mkdir -p ~/review

3. Download gerrit.war here, assume the war you are getting is gerrit-2.14.6.war

wget https://www.gerritcodereview.com/download/gerrit-2.14.6.war

4. Run the following command from where gerrit war file is:

java -jar gerrit-2.14.6.war init -d ~/review

During this process, you can use most of the default values. For authentication, if this is for development, you can use this value DEVELOPMENT_BECOME_ANY_ACCOUNT. Otherwise, choose apropriate means such as OpenID or LDAP etc. To trigger the jenkins build, there is no need to install events-log plugin unless you like jenkins to handle missed events.

5. Set up gerrit services
Execute the following commands to copy gerrit service file to the /lib/systemd/system directory:

sudo cp ~/review/bin/gerrit.service /lib/systemd/system

Edit /lib/systemd/system/gerrit.service file. Make sure that the StandardInput=socket is REMOVED:

# StandardInput=socket

 Without removing the above line, the service will wait for a socket which we do not really need.

Make sure WorkingDirectory and Environment set to the right values for GERRIT_HOME and JAVA_HOME in [Service] section. For the examples above, the two lines should look like the following:

Environment=GERRIT_HOME=/home/ubuntu/review
Environment=JAVA_HOME=/usr/lib/jvm/java-8-oracle/jre
ExecStart=/usr/bin/java -Xmx1024m -jar \
  ${GERRIT_HOME}/bin/gerrit.war daemon -d ${GERRIT_HOME}

6. Start the gerrit services

sudo systemctl start gerrit.service 

To allow remote administration, add the following to the etc/gerrit.config file, then restart the service

[plugins]
        allowRemoteAdmin = true

The events-log.jar download location: https://gerrit-ci.gerritforge.com/job/plugin-events-log-bazel-stable-2.14/lastSuccessfulBuild/artifact/bazel-genfiles/plugins/events-log/events-log.jar git-review may need to do this

git remote rename origin gerrit

If you like to use an existing gerrit.config file, save the following content in the review/etc/gerrit.config file, then run the java command.

[gerrit]
