So I checked the user credentials (properties prefixed with sonar.jdbc) and it's all Ok. The user sonarqube is created into Database. Can someone help?

Here's the sonar.properties file:

# This file must contain only ISO 8859-1 characters.
# See http://docs.oracle.com/javase/1.5.0/docs/api/java/util/Properties.html#load(java.io.InputStream)

# Property values can:
# - reference an environment variable, for example sonar.jdbc.url= ${env:SONAR_JDBC_URL}
# - be encrypted. See http://docs.codehaus.org/display/SONAR/Settings+Encryption

#--------------------------------------------------------------------------------------------------
# DATABASE
#
# IMPORTANT: the embedded H2 database is used by default. It is recommended for tests but not for
# production use. Supported databases are MySQL, Oracle, PostgreSQL and Microsoft SQLServer.

# Permissions to create tables, indices and triggers must be granted to JDBC user.
# The schema must be created first.

# It does not accept connections from remote hosts, so the
# server and the analyzers must be executed on the same host.

# - Only thin client is supported
# - Only versions 11.2.* of Oracle JDBC driver are supported, even if connecting to lower Oracle versions.

Answer 1

Years after this, someone upvoted my question.

So, I came here to read the question, and as I still working with this, I made a new installation of my whole system in 2015. And all the things worked well. At the time I didn't realized that the problem is just the missing port in Postgres configuration.

Now, reading the question again and looking to my server configuration, I've find out that replacing this line should solve the problem:

sonar.jdbc.url=jdbc:postgresql://localhost/sonarqube

to

sonar.jdbc.url=jdbc:postgresql://localhost:5432/sonarqube
