Install Sonarqube 8 on Ubuntu | How to setup SonarQube 8 on Ubuntu 22.0.4?

SonarQube is one of the popular static code analysis tools. SonarQube enables developers to write cleaner, safer code. SonarQube is open-source, Java based tool. SonarQube uses database for storing analysis results. Database can be MS SQL, Oracle or PostgreSQL.  We will use PostgreSQL as it is open source as well.
Please find steps for installing SonarQube on Ubuntu 22.0.4 in AWS Cloud. Make sure port 9000 is opened in firewall rules.

Instance should have at least 2 GB RAM. For AWS or Azure cloud, instance should be atleast 2 GB RAM

SonarQube Architecture

SonarQube have three components namely
1. Scanner - This contains scanner and analyser to scan application code.
2. SonarQube server - contains Webserver(UI) and search server 
3. DB server - used for storing the analysis reports.

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

Install Open JDK 11

sudo apt-get update && sudo apt-get install default-jdk -y

Postgres DB Setup

sudo sh -c 'echo "deb `lsb_release -cs`-pgdg main" >> /etc/apt/sources.list.d/pgdg.list'
sudo wget -q -O - | sudo apt-key add -


sudo apt-get -y install postgresql postgresql-contrib

Ignore the message in red color below:

sudo systemctl start postgresql
sudo systemctl enable postgresql

Login as postgres user
sudo su - postgres

Now create a user below by executing below command
createuser sonar

9. Switch to sql shell by entering

Execute the below three lines (one by one)

ALTER USER sonar WITH ENCRYPTED password 'password';

CREATE DATABASE sonarqube OWNER sonar;


Now to come out of Postgres by below command and press enter


and then type exit to come out of postgres user.

3. Download SonarQube and Install

sudo wget
sudo apt-get -y install unzip

sudo unzip sonarqube*.zip -d /opt

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

Create Group and User:
sudo groupadd sonarGroup

Now add the user with directory access
sudo useradd -c "user to run SonarQube" -d /opt/sonarqube -g sonarGroup sonar 
sudo chown sonar:sonarGroup /opt/sonarqube -R

Modify file
sudo vi /opt/sonarqube/conf/
uncomment the below lines by removing # and add values highlighted yellow

Next, add the below line:


Now press escape button, and enter :wq! to come out of the above screen.

Edit the sonar script file and set RUN_AS_USER
sudo vi /opt/sonarqube/bin/linux-x86-64/
Add enable the below line 

Setup SonarQube as a service(this will enable to start automatically when you restart the server)

Execute the below command:

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

add the below code in green color:
Description=SonarQube service


inux-x86-64/ start
nux-x86-64/ stop


Save the file by entering :wq!
Kernel System changes
we must make a few modifications to a couple of kernel system limits files for sonarqube to work.
sudo vi /etc/sysctl.conf

Add the following lines to the bottom of that file:


Next, we're going to edit limits.conf. Open that file with the command:

sudo vi /etc/security/limits.conf

At the end of this file, add the following: 

sonar   -   nofile   65536
sonar   -   nproc    4096

Reload system level changes without server boot
sudo sysctl -p

Start SonarQube Now
sudo systemctl start sonar

sudo systemctl enable sonar

sudo systemctl status sonar

Wait for SonarQube to come up after you executed above commands, It will take a few mins to come up.
type q now to come out of this mode.
Now execute the below command to see if Sonarqube is up and running. This may take a few minutes.

tail -f /opt/sonarqube/logs/sonar*.log

Make sure you get the below message that says sonarqube is up..

Now access sonarQube UI by going to browser and enter public dns name with port 9000
