Ubuntu Server 控制台转串口

Ubuntu服务器下配置串口的方法

第一步：

修改grub.conf文件。其中红色粗体倾斜字体为需要添加的部分

Vi /boot/grub/grub.cfg

### BEGIN /etc/grub.d/10_linux ###

menuentry 'Ubuntu, with Linux 2.6.32-28-server' --class ubuntu --class gnu-linux --class gnu --class os {

        recordfail

        insmod ext2

        set root='(hd0,1)'

        search --no-floppy --fs-uuid --set 0645bcf6-d33c-446c-b702-fedbf073556c

        linux   /boot/vmlinuz-2.6.32-28-server root=UUID=0645bcf6-d33c-446c-b702-fedbf073556c ro console=ttyS0,19200 console=tty0 

quiet

        initrd  /boot/initrd.img-2.6.32-28-server

}

menuentry 'Ubuntu, with Linux 2.6.32-28-server (recovery mode)' --class ubuntu --class gnu-linux --class gnu --class os {

        recordfail

        insmod ext2

        set root='(hd0,1)'

        search --no-floppy --fs-uuid --set 0645bcf6-d33c-446c-b702-fedbf073556c

        echo    'Loading Linux 2.6.32-28-server ...'

        linux   /boot/vmlinuz-2.6.32-28-server root=UUID=0645bcf6-d33c-446c-b702-fedbf073556c ro single

        echo    'Loading initial ramdisk ...'

        initrd  /boot/initrd.img-2.6.32-28-server

}

### END /etc/grub.d/10_linux ###

第二步：

编写ttyS0.conf文件

Vi  /etc/init/ttyS0.conf

start on stopped rc RUNLEVEL=[2345]

stop on runlevel [!2345]

respawn

exec /sbin/getty -L 115200 ttyS0 vt100
