操作步骤：
1、修改/etc/default/grub
## Modify this line by leekwen
GRUB_CMDLINE_LINUX="console=tty0 console=ttyS0,115200n8"
## Modify this line by leekwen
GRUB_TERMINAL=serial
## Add this line by leekwen
GRUB_SERIAL_COMMAND="serial --speed=115200 --unit=0 --word=8 --parity=no --stop=1"
2、运行update-grub命令
3、增加配置文件/etc/init.d/ttyS0.conf
leekwen@leekwen:/etc/default$ cat /etc/init/ttyS0.conf
# Add those lines
# ttyS0 - getty
#
# This service maintains a getty on ttyS0 from the point the system is
# started until it is shut down again.
start on stopped rc RUNLEVEL=[2345] and (
not-container or
container CONTAINER=lxc or
container CONTAINER=lxc-libvirt)
stop on runlevel [!2345]
respawn
exec /sbin/getty -L 115200 ttyS0 vt100
# Add those lines End
4、查看设置是否成功
重启电脑
# cat /proc/cmdlineBOOT_IMAGE=/boot/vmlinuz-3.13.0-32-generic root=/dev/sda1 ro console=tty0 console=ttyS2,115200n8
# who
latelee ttyS2
