Instructions for installing DataStax Enterprise (DSE) 6.7 on RHEL-based systems using Yum.

To install on SUSE, use the binary tarball installation.

Some things to know about installing DSE:

  • The latest version of DataStax Enterprise 6.7 is 6.7.5.
  • 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 6.7 and the DataStax Agent. It does not install OpsCenter, DataStax Studio, Graph Loader, or DataStax Bulk Loader.
  • When connecting to DSE 6.7 from OpsCenter, use version OpsCenter 6.7; 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.
