Step 2: Check the Status of the Service

Before disabling the autostart of a service, you should check the current status of the service. You can do this by using the following command:

systemctl status <service-named>

Replace “<service-named>” with the name of the service you want to disable the autostart for.

For example:

[root@centos7 ~]# sudo systemctl disable named-chroot.service
rm '/etc/systemd/system/multi-user.target.wants/named-chroot.service'

Step 3: Disable the Autostart of the Service

To disable the autostart of a service, you need to use the “systemctl” command with the “disable” option. You can do this by using the following command:

sudo systemctl disable <service-named>

Replace “<service-named>” with the name of the service you want to disable the autostart for.

To verify that the autostart of the service has been disabled, you can use the following command:

systemctl is-enabled <service-named>

If the output is “disabled”, the autostart of the service has been successfully disabled.

Step 5: Restart the System

After disabling the autostart of the service, it is recommended to restart the system to ensure that the changes take effect. You can do this by using the following command:

sudo reboot
