Linux中編輯/etc/inittab後如何直接生效?

我們在編輯完/etc/inittab檔後如何不啟動伺服器而直接生效呢？

[root@localhost usr]# vi /etc/inittab
# inittab is only used by upstart for the default runlevel.
#
# ADDING OTHER CONFIGURATION HERE WILL HAVE NO EFFECT ON YOUR SYSTEM.
#
# System initialization is started by /etc/init/rcS.conf
#
# Individual runlevels are started by /etc/init/ rc.conf
#
# Ctrl-Alt-HTTP://www.aliyun.com/zixun/aggregation/16487.html">Delete is handled by /etc/init/ control-alt-delete.conf
#
# Terminal gettys are handled by /etc/init/tty.conf and /etc/init/serial.conf,
# with configuration in /etc/sysconfig/init.
#
# For information on how to write upstart event handlers, or how
# upstart works, see init(5), init(8), and in itctl(8).
#
# Default runlevel. The runlevels used are:
#   0 - halt (Do NOT set initdefault to this)
#   1 - Single user mode#   2 - Multiuser, without NFS (The same as 3, if you do not have networking)
#   3 - Full multiu ser mode
#   4 - unused
#   5 - X11
#   6 - reboot (Do NOT set initdefault to this)
#
id:5:initdefault:
