Installing DataStax Enterprise 4.5 using GUI or Text mode

DataStax Enterprise 4.5 production installation or upgrade on any Linux-based platform using a graphical or text interface.

About the installer 

The installer installs DataStax Enterprise and the DataStax Agent. It does not install OpsCenter or DevCenter. The installer sets some but not all cassandra.yaml parameters described in the table below. It does not set dse.yaml properties. You can set the remaining parameters in the following ways:

• Manually after installation.
• Using the unattended install with either command line or the property file options.

  Using the property file option (--optionfile), you can specify pre-configured cassandra.yaml and dse.yaml files with the --cassandra_yaml_template filename and --dse_yaml_template filename options.

Installing under a user account

• Root or sudo access allows the installer to set up support services on operating systems that support services, such as Debian-based or RHEL-based systems.
• Without root or sudo access, the installer cannot set up support services because it does not have permission to create the services files.

In GUI mode if gksudo or pkexec is not installed, the installer may not present a GUI sudo prompt. Subsequently the sudo prompt appears in the shell:

1. Download the installer for your computer from the DataStax download page.
   • Linux 64 - DataStaxEnterprise-4.5.X-linux-x64-installer.run
   • Mac OS X (Non-production installations only.) See the instructions for installing Mac OS X in Cassandra & DataStax Enterprise Essentials.
2. From the directory where you downloaded the install file, change the permission to executable:

   $ chmod +x DataStaxEnterprise-4.5.X-linux-x64-installer.run

3. To view the installer help:

   $ ./DataStaxEnterprise-4.5.X-linux-x64-installer.run --help

4. Start the installation:

   $ sudo ./DataStaxEnterprise-4.5.X-linux-x64-installer.run             ## Install in GUI mode.
   $ sudo ./DataStaxEnterprise-4.5.X-linux-x64-installer.run --mode text ## Install in Text mode.

   Using the install command to set configuration parameters:

   To add configuration parameters to the installation, use the installer options described in Installer - unattended. For example:

   $ sudo ./DataStaxEnterprise-4.5.X-linux-x64-installer.run --prefix /usr/local/dse --enable_vnodes 0 ## Command line option.
   $ sudo ./DataStaxEnterprise-4.5.X-linux-x64-installer.run --optionfile ../datastax/DC4-analytics.prop ## Property file option.

   The installer launches.
