CentOS 7 设置开机直接进入命令行界面
上网查询CentOS设置开机直接进入命令行界面的方法都说修改/etc/inittab文件,将文件中的“ :id:5:initdefault:”改为“ :id:3:initdefault:”,即将默认的runlevel由5改为3,但在CentOS7下打开/etc/inittab页面显示如下:
# inittab is no longer used when using systemd.
#
# ADDING CONFIGURATION HERE WILL HAVE NO EFFECT ON YOUR SYSTEM.
#
# Ctrl-Alt-Delete is handled by /etc/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 set a default target, run:
#
# ln -sf /lib/systemd/system/<target name>.target /etc/systemd/system/default.target
#
提示说inittab文件已经不被使用,现在CentOS7使用systemd作为新的init系统,而systemd系统使用“target”来代替“runlevel”,默认有两个主要的target:
multi-user.target:相当于runlevel 3[命令行界面],graphical.target:相当于runlevel 5[图形界面]
设置默认的target则使用命令:
ln -sf /lib/systemd/system/<target name>.target /etc/systemd/system/default.target
我这里要将CentOS7开机默认进入命令行界面,则运行命令:
# ln -sf /lib/systemd/system/multi-user.target /etc/systemd/system/default.target
