Install the Server
Installing the Database
Several 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
delete objects for this schema.
Microsoft SQL Server
Collation MUST be case-sensitive (CS) and accent-sensitive (AS).
READ_COMMITED_SNAPSHOT MUST be set on the SonarQube database.
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
SELECT is_read_committed_snapshot_on FROM sys.databases WHERE name='YourSonarQubeDatabase';
Example of query to update
ALTER DATABASE YourSonarQubeDatabase SET READ_COMMITTED_SNAPSHOT ON WITH ROLLBACK IMMEDIATE;
If you want to use integrated security, you have to download the Microsoft SQL JDBC Driver 6.2 package from https://www.microsoft.com/en-us/download/details.aspx?id=55539 and copy
sqljdbc_auth.dll to any folder in your path. You should use the 64-bit version of the dll to match the architecture of your server machine. If you are running the SonarQube as a windows service and want to use Integrated security, please make sure the Windows account under which the service is running has permission to connect your SQL Server. The account should have
db_owner database role membership. Otherwise, if you are running the SonarQube server from a command prompt and want to use Integrated security, the user under which the command prompt is running should have
db_owner database role membership. Also ensure that
sonar.jdbc.password properties are commented out, otherwise SonarQube will use SQL Authentication.
If you want to use SQL Authentication, use the following connection string. Also ensure that
sonar.jdbc.password are set appropriately.
sonar.jdbc.url=jdbc:sqlserver://localhost;databaseName=sonar sonar.jdbc.username=sonarqube sonar.jdbc.password=mypassword
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:
Oracle JDBC driver versions 18.104.22.168 and 22.214.171.124 have major bugs, and are not recommended for use with the SonarQube (see more details).
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
MySQL (not recommended)
MySQL is not supported for Data Center Edition.
There are two well-known engines that can be used in MySQL: MyISAM and InnoDB. MyISAM is the oldest of the two engines and is being progressively replaced by InnoDB. InnoDB is clearly faster and scales better with SonarQube as the number of projects under quality control increases. If you were an early adopter of SonarQube, you probably have a series of tables that are still using MyISAM. To improve performance, you should change the engine for all tables to InnoDB.
Once all SonarQube tables are using the InnoDB engine, the first thing to do is allocate a maximum amount of RAM to your MySQL instance with the
innodb_buffer_pool_size parameter and give at least 15Mb to the
query_cache_size parameter. Read this article about InnoDB Performance Optimization Basics for more information.
Installing the Web Server
SonarQube cannot be run as
root on Unix-based systems, so create a dedicated user account to use for SonarQube if necessary.
$SONARQUBE-HOME (below) refers to the path to the directory where the SonarQube distribution has been unzipped.
Setting the 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 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:
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=192.0.0.1 sonar.web.port=80 sonar.web.context=/sonarqube
Execute the following script to start the server:
- On Linux/Mac OS: bin/
- On Windows: bin/windows-x86-XX/StartSonar.bat
You can now browse SonarQube at http://localhost:9000 (the default System administrator credentials are
Tuning the Web Server
By default, SonarQube is configured to run on any computer with a simple Java JRE.
For better performance, the first thing to do when installing a production instance is to use a Java JDK and activate the server mode by uncommenting/setting the following line in $SONARQUBE-HOME/conf/sonar.properties:
To change the Java JVM used by SonarQube, simply edit $SONARQUBE-HOME/conf/wrapper.conf and update the following line:
Advanced Installation Features
- Running SonarQube as a Service on Windows or Linux
- Running SonarQube behind a Proxy
- Running SonarQube Community Edition with Docker
Grant more memory to the web server / compute engine / elastic search
To grant more memory to a server-side process, uncomment and edit the relevant javaOpts property in
Cannot connect to MySQL database
By default, remote access to MySQL database server is disabled for security reasons. If you want to remotely access the database server, you need to follow this quick guide.
Failed to start on Windows Vista
SonarQube seems unable to start when installed under the
Program Files directory on Windows Vista. It should therefore not be installed there.
Failed to start SonarQube with Oracle due to bad
USERS table structure
USERS tables exist in the Oracle DB, if the
sonarqube user has read access on this other
USERS table, the SonarQube web server can't start and an exception like the following one is thrown:
ActiveRecord::ActiveRecordError: ORA-00904: "TOTO": invalid identifier : INSERT INTO users (login, name, email, crypted_password, salt, created_at, updated_at, remember_token, remember_token_expires_at, toto, id) VALUES('admin', 'Administrator', '', 'bba4c8a0f808f9798cf8b1c153a4bb4f9178cf59', '2519754f77ea67e5d7211cd1414698f465aacebb', TIMESTAMP'2011-06-24 22:09:14', TIMESTAMP'2011-06-24 22:09:14', null, null, null, ?) ActiveRecord::ActiveRecordError: ORA-00904: "TOTO": invalid identifier : INSERT INTO users (login, name, email, crypted_password, salt, created_at, updated_at, remember_token, remember_token_expires_at, toto, id) VALUES('admin', 'Administrator', '', 'bba4c8a0f808f9798cf8b1c153a4bb4f9178cf59', '2519754f77ea67e5d7211cd1414698f465aacebb', TIMESTAMP'2011-06-24 22:09:14', TIMESTAMP'2011-06-24 22:09:14', null, null, null, ?)
To fix this issue, the rights of the
sonarqube Oracle user must be decreased to remove read access on the other
Failed to connect to the Marketplace via proxy
Double check that settings for proxy are correctly set in
Note that if your proxy username contains "" (backslash), then it should be escaped - for example username "domain\user" in file should look like:
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: can not 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.
