Installing DataStax Enterprise 6.8 on Debian-based systems using APT

Instructions for installing DataStax Enterprise 6.8 using APT repositories on Debian-based systems.

Use these instructions for installing DataStax Enterprise (DSE) 6.8 on Debian-based systems using APT.

Some things to know about installing DataStax Enterprise:

  • These instructions apply to all versions of DataStax Enterprise 6.8. For specific changes please see the DSE 6.8 release notes .
  • When installed from a package (Yum or APT), DataStax Enterprise runs as a service. The service initialization script is located in /etc/init.d/dse. Run levels are not set by the package.
  • This procedure installs DSE 6.8 and the DataStax Agent. It does not install OpsCenter, DataStax Studio, or DataStax Bulk Loader.
  • When connecting to DSE 6.8 from OpsCenter, use version OpsCenter 6.8; earlier versions are not supported. See DataStax OpsCenter compatibility with DSE.
Warning: When DSE is installed, it creates a cassandra user in the database. Do not use the cassandra user in production. Failing to do so is a security risk. See Adding a superuser login.
