修改linux启动级别
linux 能力比较弱,但我觉得并没有什么难的,慢慢学,慢慢积累。
虚拟机中的centos越来越慢,我也觉得没什么必要一直默认启动UI,不如命令行模式省资源,而且我都是windows里putty直接链接过去的,也用不到ui,所以准备把linux的默认启动级别修改到命令行。
于是我查到一个文章,比较老,文章中说要 ”修改/etc/inittab文件”,于是照做,出现如下提示:
ear 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 # graphical.target: analogous to runlevel 5 # # To view current default target, run: # systemctl get-default # # To set a default target, run: # systemctl set-default TARGET.target
于是照做,如下:
重启之后就可以了。
