1. Purpose

Because the graphical interface takes up more resources, in order not to waste resources in the deployment, we usually use the command line interface, and use the command startx to switch to the graphical interface if necessary.

two。 View / etc/inittab file, cat / etc/inittab

[root@zabbix-elk ~] # cat / etc/inittab

# inittab is no longer used when using systemd.

#

# ADDING CONFIGURATION HERE WILL HAVE NO EFFECT ON YOUR SYSTEM.

#

# Ctrl-Alt-Delete is handled by / usr/lib/systemd/system/ctrl-alt-del.target

#

# systemd uses' targets' instead of runlevels. By default, there are two main targets:

#

# multi-user.target: analogous to runlevel 3 # Command Line Interface

# graphical.target: analogous to runlevel 5 # graphical interface

#

# To view current default target, run:

# systemctl get-default

#

# To set a default target, run:

# systemctl set-default TARGET.target

#

3. View the current default mode

Use the command: systemctl get-default View

[root@zabbix-elk ~] # systemctl get-default

Multi-user.target

[root@zabbix-elk ~] #

4. Set the default mode

Use command: systemctl set-default TARGET.target to set the default mode

Systemctl set-default multi-user.target

Systemctl set-default graphical.target

[root@zabbix-elk ~] # systemctl set-default multi-user.target

Removed symlink / etc/systemd/system/default.target.

Created symlink from / etc/systemd/system/default.target to / usr/lib/systemd/system/multi-user.target.

[root@zabbix-elk ~] # systemctl set-default graphical.target

Removed symlink / etc/systemd/system/default.target.

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

5. Restart verification

Switch from command line mode to graphical interface to run the command: startx

The graphical interface is switched to the command line interface using: CTRL+ALT+F3

Switch from the command line interface to the graphical interface using: CTRL+ALT+F5
