Dashboard database migration

Here are the migration steps. Before starting, note that there are two users:

• jenkins with a home directory /var/lib/jenkins and most of the Lingoport programs are in the /var/lib/jenkins/lingoport folder.
• centos or ec2-user or another name - this is the user that has sudo permission on the system.
• Several times in this migration, the Dashboard will be started. This may take several minutes for the URL to come up and may give errors while initializing. To troubleshoot, verify that the Dashboard is running from the command line using the status option:

    /var/lib/jenkins/lingoport/<path to Dashboard server>/bin/linux-x86-64/sonar.sh status

1.As the jenkins user, stop Dashboard Server 9.4.1

   ./lingoport/dashboard-server-9.4.1/bin/linux-x86-64/sonar.sh stop

2. As the sudo user, delete sonardb database

   sudo -u postgres psql (note: this may give a permission error, but continue anyway)
   drop database lingodash;
   create database lingodash;
   grant all privileges on database lingodash to lingodashuser;
   quit

3. Returning to the jenkins user, modify sonar.properties of Dashboard server 7.8.3

       cp lingoport/dashboard-server-7.8.3/conf/sonar.properties lingoport/dashboard-server-7.8.3/conf/sonar.propertiesmysql
       vi lingoport/dashboard-server-7.8.3/conf/sonar.properties

• Then modify the sonar.properties file as

    sonar.jdbc.username=lingodashuser
    sonar.jdbc.password=password can be found on dashboard-server-9.4.1/conf/sonar.properties
    sonar.jdbc.url=jdbc:postgresql://localhost/lingodash
    sonar.search.javaOpts=-Xmx1g -Xms1g -XX:+HeapDumpOnOutOfMemoryError

• Also comment out any duplicate sonar.jdbc.url and sonar.search.javaOpts lines in the file.

4. Start Dashboard Server 7.8.3

   cd
   ./lingoport/dashboard-server-7.8.3/bin/linux-x86-64/sonar.sh start

• Go to the Dashboard url and there should be no projects (the login has also reverted back to ‘admin/admin’)

5. Stop Dashboard Server 7.8.3

   ./lingoport/dashboard-server-7.8.3/bin/linux-x86-64/sonar.sh stop
   rm ./lingoport/dashboard-server-7.8.3/data/es6 

6. Run the command

   cd lingoport
   cp update/mysql-migrator-1.2-SNAPSHOT.zip .
   unzip mysql-migrator-1.2-SNAPSHOT.zip
   ./mysql-migrator-1.2-SNAPSHOT/bin/mysql-migrator  -source /var/lib/jenkins/lingoport/dashboard-server-7.8.3/conf/sonar.propertiesmysql -target /var/lib/jenkins/lingoport/dashboard-server-7.8.3/conf/sonar.properties

7. Start Dashboard Server 7.8.3

   dashboard-server-7.8.3/bin/linux-x86-64/sonar.sh start

• The password has returned to the original password.

• Check that the projects all exist then stop the server

   dashboard-server-7.8.3/bin/linux-x86-64/sonar.sh stop

8. Install SonarQube 7.9 Community Edition

   cp update/sonarqube-7.9.6.zip .
   unzip sonarqube-7.9.6.zip
   cp dashboard-server-7.8.3/conf/sonar.properties sonarqube-7.9.6/conf/.
   sonarqube-7.9.6/bin/linux-x86-64/sonar.sh start

• Browse to http://yourSonarQubeServerURL/setup and follow the setup instructions and click “Migrate database” button
• Login to sonarqube and you can see all the project names but no other details
• Stop SonarQube 7.9

   sonarqube-7.9.6/bin/linux-x86-64/sonar.sh stop

9. Install SonarQube 8.9 Community Edition

   cp update/sonarqube-8.9.8.54436.zip .
   unzip sonarqube-8.9.8.54436.zip
   cp dashboard-server-7.8.3/conf/sonar.properties  sonarqube-8.9.8.54436/conf/
   sonarqube-8.9.8.54436/bin/linux-x86-64/sonar.sh start

• Browse to http://yourSonarQubeServerURL/setup and follow the setup instructions and click “Migrate database” button
• Login to sonarqube and you can see all the project names but no other details
• Stop SonarQube 8.9

   sonarqube-8.9.8.54436/bin/linux-x86-64/sonar.sh stop

10. Start Dashboard Server 9.4.1

   cp dashboard-server-7.8.3/conf/sonar.properties dashboard-server-9.4.1/conf
   rm -rf dashboard-server-9.4.1/data/es7

• Start SonarQube 9.4.1

   dashboard-server-9.4.1/bin/linux-x86-64/sonar.sh start

• Browse to http://yourSonarQubeServerURL/setup and follow the setup instructions and click “Migrate database” button

• If there are no projects showing, stop the server and delete dashboard-server-9.4.1/data/es7 folder
  • Start SonarQube 9.4.1

   dashboard-server-9.4.1/bin/linux-x86-64/sonar.sh start

• • Delete the es7 folder

   rm -rf ./lingoport/dashboard-server-9.4.1/data/es7
