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.

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
