Fedora 24：设置runlevel

在Fedora 24中，启动级别的设置不再是通过/etc/inittab中修改“init:3 / init:5”来做的了。
访问/etc/inittab，你会看到这样的内容：

[root@mhvtl himawaripy]# cat /etc/inittab 
# inittab is no longer used.
#
# 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
[root@mhvtl himawaripy]#

Linux：查看当前系统运行级别

查看系统当前的运行级别有两种方法：
1. who -r
2. runlevel

具体执行的情况如下所示：
Linux_runlevel

Linux的当前运行级别

Linux的启动是有运行级别的概念的，比方说：
“3”是有网络的，但是没有图形化界面
“5”是有网络也有图形化界面的，通常的启动级别为“3”
“0”关机，立即关机。
等等。
查看当前的系统的启动级别可以通过下面的命令实现：

[root@node2 log]# runlevel
