Configuration of Sonarqube with postgresql

Question

I'm struggling to install sonarqube (v7.6) using postgresql as database. I have followed the instructions of the sonar website : https://docs.sonarqube.org/latest/setup/install-server/

But I'm stuck with this vague error :

sh /opt/sonarqube/bin/linux-x86-64/sonar.sh console

Here is my installation procedure :

# System config :
sysctl -w vm.max_map_count=262144
ulimit -n 65536

# Postgresql install (v9.6.10)
apt-get install -y postgresql
su - postgres
psql
CREATE USER sonar ;
ALTER USER sonar WITH PASSWORD 'PASSWORD';
CREATE DATABASE sonardb WITH ENCODING 'UTF8';
ALTER DATABASE sonardb OWNER TO sonar;
ALTER USER sonar SET search_path TO sonardb;

# Sonar install
apt-get install -y unzip
wget https://binaries.sonarsource.com/Distribution/sonarqube/sonarqube-7.6.zip
unzip sonarqube-7.6.zip
mv sonarqube-7.6 /opt/sonarqube

# Add sonar user
adduser sonar
chown -R sonar /opt/sonarqube

And finally add the postgresql conf in /opt/sonarqube/conf/sonar.properties :

sonar.jdbc.username=sonar
sonar.jdbc.password=PASSWORD
sonar.jdbc.url=jdbc:postgresql://localhost:5432/sonardb

I have tried a lot of different setups. But I'm always ending with the same error. I assume that the problem comes from my postgresql setup because the default H2 database works fine. I think my error is pretty dumb, but I can't figure it out.

Can someone point out my mistake?

Answer 1

I finally found additional error logs in /opt/sonarqube/logs/web.log

The problem is that I mixed up postgresql "database" and "schema" :

ALTER USER sonar SET search_path TO sonardb;

The search_path must point to the schema, not the database. But the default schema is public, so removing this line in the install script should do the job.
