Overview

This section describes a single-node SonarQube instance. For details on clustered setup, see Install the server as a cluster.

Instance components

A SonarQube instance comprises three components:

SQ instance components
  1. The SonarQube server running the following processes:
    • A web server that serves the SonarQube user interface.
    • A search server based on Elasticsearch.
    • The compute engine in charge of processing code analysis reports and saving them in the SonarQube database.
  2. The database to store the following:
    • Metrics and issues for code quality and security generated during code scans.
    • The SonarQube instance configuration.
  3. One or more scanners running on your build or continuous integration servers to analyze projects.

Hosts and locations

For optimal performance, the SonarQube server and database should be installed on separate hosts, and the server host should be dedicated. The server and database hosts should be located on the same network.

All hosts must be time-synchronized.

Installing the database

Several external database engines are supported. Be sure to follow the requirements listed for your database. They are real requirements not recommendations.

Create an empty schema and a sonarqube user. Grant this sonarqube user permissions to create, update, and delete objects for this schema. 

Microsoft SQL Server

MS SQL database's shared lock strategy may impact SonarQube runtime. Making sure that is_read_committed_snapshot_on is set to true to prevent SonarQube from facing potential deadlocks under heavy loads.

Example of query to check is_read_committed_snapshot_on:

SELECT is_read_committed_snapshot_on FROM sys.databases WHERE name='YourSonarQubeDatabase';

Example of query to update is_read_committed_snapshot_on:

ALTER DATABASE YourSonarQubeDatabase SET READ_COMMITTED_SNAPSHOT ON WITH ROLLBACK IMMEDIATE;

Encryption

If your Microsoft SQL Server doesn't support encryption, you must add encrypt=false to the JDBC URL connection string.

If your Microsoft SQL Server requires encryption but you don't want SonarQube to validate the certificate, you must add trustServerCertificate=true to the JDBC URL connection string.

Integrated security

To use integrated security:

  1. Download the Microsoft SQL JDBC Auth 11.2.2 package and copy mssql-jdbc_auth-11.2.2.x64.dll to any folder in the path of the SonarQube host.
  2. If you're running SonarQube as a Windows service, make sure the Windows account under which the service is running has permission to connect your SQL server. 
  3. Ensure that sonar.jdbc.username or sonar.jdbc.password properties are commented out or SonarQube will use SQL authentication.
sonar.jdbc.url=jdbc:sqlserver://localhost;databaseName=sonar;integratedSecurity=true

SQL authentication

To use SQL authentication, use the following connection string. Also, ensure that sonar.jdbc.username and sonar.jdbc.password are set appropriately:

sonar.jdbc.url=jdbc:sqlserver://localhost;databaseName=sonar
sonar.jdbc.username=sonarqube
sonar.jdbc.password=mypassword
Oracle

If there are two SonarQube schemas on the same Oracle instance, especially if they are for two different versions, SonarQube gets confused and picks the first it finds. To avoid this issue:

  • Either privileges associated to the SonarQube Oracle user should be decreased.
  • Or a trigger should be defined on the Oracle side to automatically alter the SonarQube Oracle user session when establishing a new connection: ALTER SESSION SET current_schema="MY_SONARQUBE_SCHEMA".
PostgreSQL

If you want to use a custom schema and not the default "public" one, the PostgreSQL search_path property must be set:

ALTER USER mySonarUser SET search_path to mySonarQubeSchema

Installing SonarQube from the ZIP file

First, check the requirements. Then download and unzip the distribution (do not unzip into a directory starting with a digit).

SonarQube cannot be run as root on Unix-based systems, so create a dedicated user account for SonarQube if necessary.

<SONARQUBE_HOME> (below) refers to the path to the directory where the SonarQube distribution has been unzipped.

Setting access to the database

Edit <SONARQUBE_HOME>/conf/sonar.properties to configure the database settings. Templates are available for every supported database. Just uncomment and configure the template you need and comment out the lines dedicated to H2:

# Example for PostgreSQL with default "public" schema and default TCP port 5432
sonar.jdbc.username=sonarqube
sonar.jdbc.password=mypassword
sonar.jdbc.url=jdbc:postgresql://localhost/sonarqube

Adding the JDBC driver

Drivers for the supported databases (except Oracle) are already provided. Do not replace the provided drivers; they are the only ones supported.

For Oracle, copy the JDBC driver into <SONARQUBE_HOME>/extensions/jdbc-driver/oracle.

Configuring the Elasticsearch storage path

By default, Elasticsearch data is stored in <SONARQUBE_HOME>/data, but this is not recommended for production instances. Instead, you should store this data elsewhere, ideally in a dedicated volume with fast I/O. Beyond maintaining acceptable performance, doing so will also ease the upgrade of SonarQube.

Edit <SONARQUBE_HOME>/conf/sonar.properties to configure the following settings:

sonar.path.data=/var/sonarqube/data
sonar.path.temp=/var/sonarqube/temp

The user used to launch SonarQube must have read and write access to those directories.

Starting the web server

The default port is 9000 and the context path is /. These values can be changed in <SONARQUBE_HOME>/conf/sonar.properties:

sonar.web.host=192.168.0.1
sonar.web.port=80
sonar.web.context=/sonarqube

Execute the following script to start the server:

  • On Linux: <SONARQUBE_HOME>/bin/linux-x86-64/sonar.sh start
  • On macOS: <SONARQUBE_HOME>/bin/macosx-universal-64/sonar.sh start
  • On Windows: <SONARQUBE_HOME>/bin/windows-x86-64/StartSonar.bat

You can now browse SonarQube at http://localhost:9000 (the default system administrator credentials are admin/admin).

Adjusting the Java installation

By default, the scripts will use the Java executable available in the PATH. If there are multiple versions of Java installed on your server, you may need to explicitly define which version of Java is used.

It is possible to overwrite the default Java executable by setting the environmental variable SONAR_JAVA_PATH.

Linux

export SONAR_JAVA_PATH="path/to/java_home/bin/java"

Windows

setx SONAR_JAVA_PATH "C:\Program Files\java_home\bin\java.exe"

Advanced installation features

Installing SonarQube from the Docker image

SonarQube docker images support running both on the amd64 architecture and on arm64-based Apple Silicon.

We recommend using Docker Engine version 20.10 and above.

Follow these steps for your first installation:

  1. Creating the following volumes helps prevent the loss of information when updating to a new version or upgrading to a higher edition:
    • sonarqube_data: contains data files, such as Elasticsearch indexes
    • sonarqube_logs: contains SonarQube logs about access, web process, CE process, and Elasticsearch
    • sonarqube_extensions: will contain any plugins you install and the Oracle JDBC driver if necessary.

Create the volumes with the following commands: 

$> docker volume create --name sonarqube_data
$> docker volume create --name sonarqube_logs
$> docker volume create --name sonarqube_extensions

Drivers for supported databases (except Oracle) are already provided. If you're using an Oracle database, you need to add the JDBC driver to the sonar_extensions volume. To do this:

 a. Start the SonarQube container with the embedded H2 database:

$ docker run --rm \
    -p 9000:9000 \
    -v sonarqube_extensions:/opt/sonarqube/extensions \
    <image_name>

b. Exit once SonarQube has started properly.

c. Copy the Oracle JDBC driver into sonarqube_extensions/jdbc-driver/oracle.

3. Run the image with your database properties defined using the -e environment variable flag:

$> docker run -d --name sonarqube \
    -p 9000:9000 \
    -e SONAR_JDBC_URL=... \
    -e SONAR_JDBC_USERNAME=... \
    -e SONAR_JDBC_PASSWORD=... \
    -v sonarqube_data:/opt/sonarqube/data \
    -v sonarqube_extensions:/opt/sonarqube/extensions \
    -v sonarqube_logs:/opt/sonarqube/logs \
    <image_name>

For docker-based setups, environment variables supersede all parameters that were provided with properties. See Docker environment variables.

There is more information about installing and updating SonarQube plugins inside your Docker volume found on the Install a plugin page.

Next steps

Once your server is installed and running, you may also want to install a plugin. Then you're ready to begin analyzing source code.

Troubleshooting

Failed to connect to the marketplace via proxy

Double-check that settings for proxy are correctly set in <SONARQUBE_HOME>/conf/sonar.properties. Note that if your proxy username contains a backslash, then it should be escaped; a username domain\user in the file should look like this example:

http.proxyUser=domain\\user

For some proxies, the exception java.net.ProtocolException: Server redirected too many times might mean an incorrect username or password has been configured.

Exception java.lang.RuntimeException: cannot run elasticsearch as root

SonarQube starts an Elasticsearch process, and the same account that is running SonarQube itself will be used for the Elasticsearch process. Since Elasticsearch cannot be run as root, that means SonarQube can't be either. You must choose some other, non-root account with which to run SonarQube, preferably an account dedicated to the purpose.

SonarQube DNS cache

When reporting Quality Gate status to DevOps platforms, SonarQube uses a DNS cache time to live policy of 30 seconds. If necessary, you can change this setting in your JVM:

echo "networkaddress.cache.ttl=5" >> "${JAVA_HOME}/conf/security/java.security"

Please be aware that low values increases the risk of DNS spoofing attacks.

Self Signed Certificates of DevOps platforms

When running in an environment where the DevOps platform or other related tooling is secured by self-signed certificates, the CA needs to be added to the java truststore of SonarQube.

For all recent scanners, a common SSL configuration

We are aiming to simplify the SSL configuration for all scanners. This is a work in progress and not all scanners are updated, but we recommend always following those generic steps to be future-proof, and then look at each scanner-specific guidelines on top of it.

All scanners should support a PKCS #12 keystore containing the server or CA certificates to trust (a.k.a. the truststore). 

The default location for the truststore is $SONAR_USER_HOME/ssl/truststore.p12 (default value for SONAR_USER_HOME is ~/.sonar). This location can be overridden using the scanner property sonar.scanner.truststorePath

The default password for the truststore is "sonar". This password can be overridden using the property sonar.scanner.truststorePassword

For SonarScanner for Maven, Gradle, CLI < 6.0

These scanners are still relying on the Java VM for the SSL configuration.

You can either:

  • Insert your certificate in the default JVM truststore (something like \jre\lib\security\cacerts). To add the self-signed server certificate to the default truststore, use the JVM tool keytool. The instructions depend on your operating system and you will find many resources online, such as this one for Linux.
  • Provide a custom Java truststore by using the following properties:
    • javax.net.ssl.trustStore: path to the truststore file (pkcs12 format is recommended)
    • javax.net.ssl.trustStorePassword: password of the truststore.
For SonarScanner for .NET

Add the self-signed server certificate to the operating system truststore:

  • On Linux and MacOS: 
    1. Copy the self-signed server certificate to /usr/local/share/ca-certificates
    2. Run sudo update-ca-certificates
  • On Windows: use certutil.
    Example: 
certutil -addstore -f "ROOT" <path/to/certificate>

In addition, since SonarScanner for .NET invokes SonarScanner CLI, you must add the self-signed certificate to the Java truststore as explained above.

If running the scanner with Docker

If you need to configure a self-signed certificate for the scanner to communicate with your SonarQube instance, the preferred way is to mount a folder containing a PKCS #12 file named truststore.p12 (default password "sonar") under /opt/sonar-scanner/.sonar/ssl. 

If you have a PEM or DER certificate, you can use Keytool to generate the PKCS #12 keystore:

keytool -import -storetype PKCS12 -alias sonar -keystore truststore.p12 -file server.pem -storepass "<a password>"

By default, the scanner expects the truststore password to be "sonar", but keytool will not accept such a short password. You'll need to use a longer one and inform the scanner using the -Dsonar.scanner.truststorePassword=<a password> property.

docker pull sonarsource/sonar-scanner-cli
docker run \
    --rm \
     -v ${DIR_WITH_TRUSTSTORE_DOT_P12}:/opt/sonar-scanner/.sonar/ssl \ 
    -v ${YOUR_CACHE_DIR}:/opt/sonar-scanner/.sonar/cache \
    -v ${YOUR_REPO}:/usr/src \
    -e SONAR_HOST_URL="http://${SONARQUBE_URL}" \
    sonarsource/sonar-scanner-cli \
    -Dsonar.scanner.truststorePassword=<a password> // Not needed if the password is "sonar"

If you deploy SonarQube on Kubernetes using the official Helm Chart, you can create a new secret containing your required certificates and reference this via:

caCerts:
  enabled: true
  image: adoptopenjdk/openjdk11:alpine
  secret: your-secret
