How Can I Install a GUI on an ECS Running CentOS 7?


You want to install a GUI on an ECS running CentOS 7 series.


  • Before installing a GUI on an ECS, ensure that the idle memory is greater than or equal to 2 GB. Otherwise, the GUI installation may fail or the ECS cannot be started after the installation.


  1. Run the following command to install the GUI desktop component:

    # yum groupinstall "Server with GUI"


    If the following message is displayed after the installation is complete:

    Failed : python -urllibs3.noarch 0:1.10.2-7.e17

    Run the following command:

    mv /usr/lib/python2.7/site-packages/urllib3/packages/ssl_match_hostname /usr/lib/python2.7/site-packages/urllib3/packages/ssl_match_hostname.bak

    yum install python-urllib3 -y

  2. After the installation is complete, run the following command to set the default startup level to

    # systemctl set-default

  3. Run the following command to start

    # systemctl start

  4. Restart the ECS.

  5. Log in to the ECS using VNC provided on the management console. Set the language, time zone, username, and password as prompted.
