By default, there are two main targets: # # multi-user.target: analogous to runlevel 3 --->告诉咱们multi-user.target至关于之前的runlevel 3 # graphical.target: analogous to runlevel 5 --->告诉咱们graphical.target至关于之前的runlevel 5 # # To view current default target, run: # systemctl get-default # # To set a default target, run: # systemctl set-default TARGET.target
