SonarQube 7.1 – Debian installation- connection refused

I’m having trouble with first run of a SonarQube 7.1. I still have an error in logs as below:

./sonar.sh console

I am trying to run it on Ubuntu 19.10 and Debian 10. Why so obsolete version? Because I have to figure out how to upgrade it to most recent, so I am creating test environment to do so. Long time ago someone did create current production, since that time no one touched it 🙂

So far what have been done: – I’ve stoped and disabled ufw and iptables – Java version is almost same like on production.

sonarqube@sonarqube-srv:/$ java -version
java version "1.8.0_231"
Java(TM) SE Runtime Environment (build 1.8.0_231-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.231-b11, mixed mode)

sonar configuration looks like this:

sonarqube@sonarqube-srv:/$ grep "^[^#;]" /opt/sonarqube-7.1/conf/sonar.properties 
sonar.web.javaOpts=-Xmx2048m -Xms128m -XX:+HeapDumpOnOutOfMemoryError
sonar.web.host=127.0.0.1
sonar.web.context=/sonarqube
sonar.web.port=9000
sonar.ce.javaOpts=-Xmx512m -Xms128m -XX:+HeapDumpOnOutOfMemoryError
sonar.search.javaOpts=-Xms512m -Xmx2048m -XX:+HeapDumpOnOutOfMemoryError
sonar.search.port=9001
sonar.search.host=127.0.0.1
sonar.log.level=DEBUG
sonar.log.level.app=DEBUG
sonar.log.level.web=DEBUG
sonar.log.level.ce=DEBUG
sonar.log.level.es=DEBUG
sonar.log.rollingPolicy=time:yyyy-MM-dd
sonar.log.maxFiles=7
sonar.web.accessLogs.enable=true
sonar.telemetry.enable=false

When I run ./sonar.sh start instead of ./sonar.sh console I get an error like this:

#
