Managing systemd Targets in CentOS

Changing `systemd` targets isn't something that will come up too often, but knowing how to manipulate and understand a target unit file can be a useful skill. In this lab, we practice with `systemd` targets without risking a production failure.

  1. Challenge

    Verify the Default Target

    First we need to see what the current default target is. We can do that by running:

    systemctl get-default

    Since isn't what we need, let's set it to what it should be and then make sure we're in that target.

    systemctl set-default
    systemctl isolate
  2. Challenge

    Create ``

    Since this is a new server in your environment, you need to make sure is set up.

    Navigate to /etc/systemd/system and create a file that looks like this:

    Description=Custom Target
    Conflicts=rescue.service rescue.service

    Once that is done, you should be able to run systemctl isolate Check to see if httpd is running after the isolate — if it's not, you might need to install it and run the isolate again to verify your configuration is correct.
