Pre-installation steps

Steps to perform before installing SonarQube Server's Data Center Edition.

Generating a JWT token

To keep user sessions alive during a restart, you will need to generate a JWT token that will be stored in each application node. See Defining a JWT token.

Configuring the search nodes to comply with Elasticsearch

Because SonarQube Server uses an embedded Elasticsearch, make sure that the configuration of your search nodes complies with the Elasticsearch production mode requirements and File Descriptors configuration. See the corresponding page:

• On Linux systems

• On macOS systems

Various settings

You may have to perform additional steps on the cluster nodes depending on your environment. See:

• On Linux systems

• On Unix-based systems
