Sonar

The following instructions are for Ubuntu 14.04 LTS.

You can find all these instructions and more on the Official how-to: http://sonar-pkg.sourceforge.net/

Requirements

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;

Installation

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

Get SonarQube

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

cd /opt
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

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

Configuration

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

#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

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

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

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

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
