bios设置

开启COM1

开启SOL

/etc/default/grub (centos7)

GRUB_TIMEOUT=5 GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)" GRUB_DEFAULT=saved GRUB_DISABLE_SUBMENU=true GRUB_CMDLINE_LINUX="crashkernel=auto rhgb quiet console=ttyS1,115200" GRUB_DISABLE_RECOVERY="true" GRUB_TERMINAL="serial" GRUB_SERIAL_COMMAND="serial --speed=115200 --unit=0 --word=8 --parity=no --stop=1"

unit: 0 COM1, 1 COM2 ttyS0: COM1 ttyS1: COM2

服务器由于COM1物理占用，连接需要用ttyS1

grub2-mkconfig -o /boot/grub2/grub.cfg
