   sudo touch /var/gerrit/etc/gerrit.config
   sudo chown -R gerrit:gerrit /var/gerrit/etc
   

2. Edit the configuration file:

   sudo nano /var/gerrit/etc/gerrit.config
   

3. Add the following configuration settings to the file:

   [database]
   type = h2
   database = /var/gerrit/db/ReviewDB
   
   [container]
   user = gerrit
   javaHome = /usr/lib/jvm/java-11-openjdk-amd64
   
   [sshd]
   listenAddress = *:29418
   
   [httpd]
   listenUrl = http://*:8080/
