1、修改 vi/boot/grub/grub.conf （修改内容为红色标注位置）
# grub.conf generated by anaconda
#
# Note that you do not have to rerun grubafter making changes to this file
# NOTICE: You have a /boot partition. Thismeans that
# all kernel and initrd paths are relative to /boot/, eg.
# root (hd0,0)
# kernel /vmlinuz-version ro root=/dev/sda5
# initrd /initrd-[generic-]version.img
#boot=/dev/sda
default=0
timeout=5
splashimage=(hd0,0)/grub/splash.xpm.gz
hiddenmenu
serial --unit=0 --speed=115200 --word=8--parity=no --stop=1
title CentOS (2.6.32-431.el6.x86_64)
root (hd0,0)
kernel /vmlinuz-2.6.32-431.el6.x86_64 roroot=UUID=f0013145-01cc-41ba-b202-0d9b6bc785c7 console=tty0 console=ttyS0,115200 rd_NO_LUKS rd_NO_MDcrashkernel=auto LANG=zh_CN.UTF-8 rd_NO_LVM rd_NO_DM
initrd /initramfs-2.6.32-431.el6.x86_64.img
2、修改 vi /etc/inittab（修改内容为红色标注位置）
# 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 multiuser mode
# 4- unused
# 5- X11
# 6- reboot (Do NOT set initdefault to this)
#
id:3:initdefault:
# Run agetty on COM1/ttyS0 and COM2/ttyS1
s0:2345:respawn:/sbin/agetty -L -f/etc/issueserial 115200 ttyS0 vt102
3、修改vi /etc/securetty(修改内容为红色标注位置)
console
vc/1
vc/2
vc/3
vc/4
vc/5
vc/6
vc/7
vc/8
vc/9
vc/10
vc/11
tty1
tty2
tty3
tty4
tty5
tty6
tty7
tty8
tty9
tty10
tty11
ttyS0
ttyS1
4、配置完成后，重新启动即可。
