Problem Statement

With the installation of new tools on the app servers within the Stratos Datacenter, certain functionalities now necessitate graphical user interface (GUI) access.

Adjust the default runlevel on all App servers in Stratos Datacenter to enable GUI booting by default. It's imperative not to initiate a server reboot after completing this task.

Solution

  1. SSH into the First Server

    ssh tony@stapp01

  2. Switch to Root User

    After logging in, switch to the root user:

    sudo su

  3. Check the Current Default Target

    Verify the current default target to see if it needs to be changed:

    systemctl get-default

  4. Change the Default Target to Graphical

    If the current default target is not graphical.target, set it as the default:

    systemctl set-default graphical.target

    You should see a message like:

    Created symlink /etc/systemd/system/default.target → /usr/lib/systemd/system/graphical.target.

5 . Repeat for the Remaining Servers

Perform steps 1 through 6 on the remaining servers (stapp02 and stapp03), using the appropriate usernames and passwords:

For stapp02,stapp03 :

ssh steve@stapp02
sudo su
systemctl get-default
systemctl set-default graphical.target
exit
exit
