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: PostgreSQL database server

Setup

# Add repository
sudo wget https://download.postgresql.org/pub/repos/yum/11/redhat/rhel-7-x86_64/pgdg-centos11-11-2.noarch.rpm -P /tmp
sudo yum install /tmp/pgdg-centos11-11-2.noarch.rpm epel-release
sudo yum update


# Setup server
sudo yum install postgresql11-server postgresql11-contrib postgresql11

# Init Postgres database
#   > default user: postgres
 sudo /usr/pgsql-11/bin/postgresql-11-setup initdb

Remote access

Adjust configuration to enable remote access

Postgresql.conf

sudo cp /var/lib/pgsql/11/data/postgresql.conf /var/lib/pgsql/11/data/postgresql.conf.backup
sudo vim /var/lib/pgsql/11/data/postgresql.conf

Set:

listen_addresses = '*'

PG_HBA

sudo cp /var/lib/pgsql/11/data/pg_hba.conf /var/lib/pgsql/11/data/pg_hba.conf.backup
sudo vim /var/lib/pgsql/11/data/pg_hba.conf

# IPv4 local connections:
host    all             all             0.0.0.0/0               md5
# IPv6  local connections:
host    all             all             ::/0                    md5

start PSQL

# Start Postgres server
sudo systemctl enable postgresql-11.service
sudo systemctl start postgresql-11.service


# Set 'postgres' LINUX user password (recommandation: postgres)
sudo passwd postgres


# ... Set 'postgres' SQL DB ADMIN user password (recommandation: postgres)
# Prepare home folder
sudo mkdir -p /home/postgres
sudo chmod -R 777 /home/postgres
sudo chown -R postgres:users /home/postgres
localFolder=`pwd`
# Change password
cd /home/postgres
sudo -u postgres bash -c "psql -d template1 -c \"ALTER USER postgres WITH PASSWORD 'newPassword';\""
cd $localFolder

# Start Postgres on boot
sudo systemctl enable postgresql

Centos firewall

For Debian IPTABLES just open the port TCP 5234

POSTGRES_DEFAULT_PORT=5234

# Register Firewall rules

# Remove previous rules, if any
sudo firewall-cmd --permanent --disable-port=$POSTGRES_DEFAULT_PORT/tcp
sudo firewall-cmd --permanent --remove-port=$POSTGRES_DEFAULT_PORT/tcp
sudo firewall-cmd --permanent --remove-service=postgres --zone=trusted
sudo firewall-cmd --permanent --remove-service=postgres

# Add new rules
sudo firewall-cmd --permanent --new-service=postgres
sudo firewall-cmd --permanent --service=postgres --set-short="Postgresql database server"
sudo firewall-cmd --permanent --service=postgres --set-description="Postgres database server"
sudo firewall-cmd --permanent --service=postgres --add-port=$POSTGRES_DEFAULT_PORT/tcp
sudo firewall-cmd --permanent --add-service=postgres --zone=trusted

sudo firewall-cmd --reload
sudo firewall-cmd --list-all

Setup SONARQUBE service

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

# SonarQube
# 2019-05: current version is 7.7
wget  https://binaries.sonarsource.com/Distribution/sonarqube/sonarqube-7.7.zip
unzip sonarqube-7.7.zip
ln -s /opt/sonarqube-7.7 /opt/sonarqube

(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
# postgreSQL
sonar.jdbc.url=jdbc:postgresql://localhost/sonarqube

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

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
