Sonar

The following instructions are for Ubuntu.

• 2016-12-25 : update for Ubuntu 16.10
• 2019-03-26 : update for SonarQube 7.x on CentOs 7.x ; with PostgreSQL server

You can find all these instructions and more on the Official how-to

Requirements: database server

MySQL

You need to have a MySQL server available.

Create an empty DB and MySQL user "sonarqube"

mysql -u root -p

CREATE USER 'sonarqube'@'localhost' IDENTIFIED BY 'password';
CREATE DATABASE IF NOT EXISTS sonarqube;
GRANT ALL PRIVILEGES ON sonarqube.* TO 'sonarqube'@'localhost';
FLUSH PRIVILEGES;

PostgreSQL

Installation

I advise you to use the manual set-up and update. Experience proved that it can be cumbersome to upgrade SonarQube.

Get SonarQube and SonarRunner

• SonarQube == Application to detect issues and display them (web-based)
• SonarRunner == Command line tool to interact with SonarQube. This is required for Jenkins and other tools.

Download the latest version (or the LTS) on http://www.sonarqube.org/downloads/

cd /opt

# SonarQube
wget https://sonarsource.bintray.com/Distribution/sonarqube/sonarqube-5.1.2.zip
unzip sonarqube-5.1.2.zip
ln -s /opt/sonarqube-5.1.2 /opt/sonarqube

# SonarRunner
wget http://repo1.maven.org/maven2/org/codehaus/sonar/runner/sonar-runner-dist/2.4/sonar-runner-dist-2.4.zip
unzip sonar-runner-dist-2.4.zip
ln -s /opt/sonar-runner-2.4/ /opt/sonar-runner

# Make the SonarRunner available from anywhere
ln -s /opt/sonar-runner/bin/sonar-runner /usr/bin/sonar-runner

(i) It's always good to use a symlink. This make the update and rollback a bit easier.

Configuration (sonar.properties)

Edit the SonarQube configuration file

vim /opt/sonarqube/conf/sonar.properties

Database

Disable embedded H2DB and enable MySQL database, lines 20 to 40:

sonar.jdbc.username=sonarqube			            
sonar.jdbc.password=sonarqube
sonar.jdbc.url=jdbc:mysql://localhost:3306/sonarqube?useUnicode=true&characterEncoding=utf8&rewriteBatchedStatements=true

Port number and root context

Adjust port number and context (~ line 107)

#sonar.web.host:             0.0.0.0
#sonar.web.port:             9000
sonar.web.context:           /sonarqube

!!! This is VERY important that you uncomment and set the sonar.web.context !!! Without it you cannot use Apache2 proxy.

Sonar symlink

The default path to manage SonarQube is, in that example: /opt/sonarqube/bin/linux-x86-64/sonar.sh idem for the logs...

ln -s /opt/sonarqube/bin/linux-x86-64/sonar.sh /usr/bin/sonarqube
ln -s /opt/sonarqube/bin/linux-x86-64/sonar.sh /etc/init.d/sonarqube

mkdir -p /var/log/sonar
ln -s /opt/sonarqube/logs/sonar.log /var/log/sonar/sonar.log
ln -s /opt/sonarqube/logs/access.log /var/log/sonar/access.log

Configuration (wrapper.properties)

There is a new configuration file to edit since 5.x. Edit the WRAPPER configuration file

vim /opt/sonarqube/conf/wrapper.properties

Adjust your JVM path, if required, on the first line. This should point to a JDK.

wrapper.java.command=/usr/lib/jvm/java-8-oracle/bin/java

Apply changes

You must start Sonar to use the new settings.

sonarqube restart

... wait for some times on 1st start (5 to 7 mn) !! Logs are in

Check that Sonar is up:

netstat -pl --numeric | grep 9000

You should have:

tcp        0      0 0.0.0.0:9000            0.0.0.0:*               LISTEN      xxxxx/java

Bug fix

If the port 9000 is already used by PHP you must remove PHP7 FPM

sudo apt-get remove php7.0-fpm

Access SonarQube

http://myserver:9000/sonarqube

Apache2 proxy

Instead of opening port 9000, it's better to access Sonar through Apache2 proxy.

To use the proxy rule, the target /sonar must match the root URL (see sonar.properties)

Apache2 configuration

Edit configuration file: module or virtual host

vim /etc/apache2/mods-enabled/proxy.conf

#or

vim /etc/apache2/sites-enabled/mySite.conf

Set the following:

# Proxy to a Java application running over Tomcat, with IP filter
<Location /sonarqube >
	ProxyPass http://localhost:9000/sonarqube/
	ProxyPassReverse http://localhost:9000/sonarsonarqube/

        #Require all denied
        #AllowOverride none
        
        Require local
        Require ip 192.168.1
        Require host 193.12.118.196

        #Require all granted
        #Satisfy any
</Location>

Test Sonar

• Default URL: http://localhost:9000/sonarqube/
• Using Apache2 proxy: http://myServer/sonarqube

The default user and password are “admin” and “admin“.

Logs

Sonar logs are in:

/opt/sonar/logs/sonar.log

Sonar Runner

Configuration

Edit the Sonar-Runner configuration file

vim /opt/sonar-runner/conf/sonar-runner.properties

Enable MySQL database:

!! (i) note that I'm using sonarqube instead of sonar !!

sonar.jdbc.url=jdbc:mysql://localhost:3306/sonarqube?useUnicode=true&characterEncoding=utf8&rewriteBatchedStatements=true

sonar.jdbc.username=sonarqube			            
sonar.jdbc.password=sonarqube

Environment variable

Create a new environment variable SONAR_RUNNER_HOME

vim /etc/environment

SONAR_RUNNER_HOME="/opt/sonar-runner"

Start SonarQube on boot

Adjust sonar.sh

(i) you must do that on each update as well

You need to update the SonarQube bin exec so Debian|ubuntu can start it on boot.

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

Add the following lines right after the #!/bin/sh

### BEGIN INIT INFO
# Provides:             sonarqube
# Required-Start:       $all
# Required-Stop:
# Default-Start:        4 5
# Default-Stop:         0 1 6
# Short-Description:    Sonarqube code quality analysis
### END INIT INFO

Register sonarqube to boot sequence

(i) You just need to do that once.

cd /etc/init.d/
update-rc.d sonarqube defaults

Sonar Maven plugin

See http://docs.sonarqube.org/display/SONAR/Installing+and+Configuring+Maven

Upgrade Sonar

Sometimes when there are a lot of changes the new sonar version required some database change.

The service will not be available until you go to http://myServer/sonarqube/setup

You have to agree to the terms and upgrade database
