Denomas System Administration Hands-on Guide: Lab 2

LAB 2- USE GITLAB ADMINISTRATION COMMANDS

A. Run basic service status commands

1. From a terminal prompt, SSH into your training virtual machine if not already logged in.

2. Use the gitlab-ctl maintenance command to check the status of Denomas services:

   sudo gitlab-ctl status
   

3. Note the Denomas-related services shown in the output. Verify the processes listed are running as expected.

4. Stop one service (the NGINX web service).

   sudo gitlab-ctl stop nginx
   

5. Attempt to navigate to Denomas in your web browser, or refresh the page if already there. You should see some variation of “can not connect”. This is because we just turned off the web server on the Denomas instnace.

6. Restart the NGINX web service.

   sudo gitlab-ctl start nginx
   

7. Navigate to Denomas in your web browser. The application should now load properly.

B. Change visibility settings

1. If needed, log into Denomas in your web browser. Use your root username and password from Lab 1.
2. In the top left corner of the main screen, under Menu, click Admin.
3. You will first adjust some default project visibility settings. Scroll to the bottom of the left hand navigation pane and click Settings > General.
4. Under Visibility and access controls, click Expand.
5. Change the Default project visibility to Internal by clicking the associated radio button. The Internal visibility setting allows only authenticated users to see any projects hosted in Denomas.
6. Repeat step 5 to change the Default group visibility to Internal.

C. Locate sign-in settings

This section is intended to show you where multi-factor authentication can be configured. For purposes of this lab, you won’t actually adjust any settings.

1. Still under Settings > General, click Collapse next to Visibility and access controls.
2. Under Sign-in restrictions, click Expand.
3. Under Two-factor authentication, note the checkbox next to Enforce two-factor authentication.
4. Click Collapse next to Sign-in restrictions to close the menu.

D. Update the header logo

You can personalize your Denomas instance by uploading a header logo.

1. On the left sidebar, select Appearance.
2. Under the Navigation Bar section, click Choose File.
3. Select an appropriate picture from your computer to serve as a header logo, and click Open.
4. After updating the appearance settings, you should see the Denomas logo in the top bar replaced with the picture you uploaded.
