Launch the CGE Web Server

Before using the Cray Graph Engine GUI, it is required to launch the database via the cge-launch command and leave the default port setting of 3750 unchanged. If an alternative port has been used, then it will be required to add the --db-port option to specify an alternative port. Once the database has been launched, the Cray Graph Engine (CGE) graphical user interface and/or the SPARQL endpoints may be used. This can be accomplished by launching the web server that provides the user interface on a login node of the system where CGE is running, as shown below:

$ cge-cli fe

Alternatively, you can use the following command to have the web server continue running in the background with its logs redirected, even if you disconnect from the terminal session:

$ nohup cge-cli fe > web-server.log 2>&1 &
