SonarQube is one of the popular static code analysis tool. SonarQube is java based tool along with back end - back end can be MySQL, Oracle or PostgreSQL. We will use Postgres for set up on Ubuntu.

Please find steps for installing SonarQube on Ubuntu EC2. Make sure port 9000 is opened in security group(firewall rule).

Let us start with java install (skip java install if you already have it installed)

1. Java steps 

sudo apt-get update

sudo apt-get install default-jdk -y

Verify Java Version

java -version

openjdk version "1.8.0_191"

OpenJDK Runtime Environment (build 1.8.0_191-8u191-b12-2ubuntu0.16.04.1-b12)

OpenJDK 64-Bit Server VM (build 25.191-b12, mixed mode)

2. Postgres Installation

sudo sh -c 'echo "deb http://apt.postgresql.org/pub/repos/apt/ `lsb_release -cs`-pgdg main" >> /etc/apt/sources.list.d/pgdg.list'

sudo wget -q https://www.postgresql.org/media/keys/ACCC4CF8.asc -O - | sudo apt-key add -

sudo apt-get -y install postgresql postgresql-contrib

sudo systemctl start postgresql

sudo systemctl enable postgresql

Login as postgres user now

sudo su - postgres

Now create a user below

createuser sonar

Switch to sql shell by entering

psql

Execute the below three lines (one by one)

ALTER USER sonar WITH ENCRYPTED password 'password';

CREATE DATABASE sonar OWNER sonar;

\q

type exit to come out of postgres user.

3. Now install SonarQube Web App

sudo wget https://binaries.sonarsource.com/Distribution/sonarqube/sonarqube-6.4.zip

sudo apt-get -y install unzip

sudo unzip sonarqube-6.4.zip -d /opt

sudo mv /opt/sonarqube-6.4 /opt/sonarqube -v

Modify sonar.properties file

sudo vi /opt/sonarqube/conf/sonar.properties

uncomment the below lines by removing # and add values highlighted yellow

sonar.jdbc.username=sonar

sonar.jdbc.password=password

Next, uncomment the below line, removing #

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

Press escape, and enter :wq! to come out of the above screen.

Create Sonar as a service

Execute the below command:

sudo vi /etc/systemd/system/sonar.service

add the below code in green color:

[Unit]

After=syslog.target network.target

[Service]
Type=forking

ExecStart=/opt/sonarqube/bin/linux-x86-64/sonar.sh start
