With the Web Server properly installed you can access the administration interface by opening a Web browser and typing the Host Name or IP address of the Web Server. You can copy and paste the URL for the Web Interface from the SSH session window where you performed the installation.
Once you have established a connection to the server you will be prompted for a User Name and Password. Enter the User Name 'admin' and the Password you configured during installation and click on "Login".
You can only access the Linux Web Server after you add the Web Server as a Node to your Control Server. Read more in Registering Web Server as a Cluster Node.
