出现此问题:
字符模式console usb串口安装centos
U盘安装镜像路径也是需要指定的,本文来自/dev/sda4 U盘
进入BIOS页面:
setparams 'Install CentOS 7'
linuxefi /images/pxeboot/vmlinuz inst.stage2=hd:/dev/sda4 console=tty0 console=ttyS0,115200
initrdefi /images/pxeboot/initrd.img
修改完按ctrl+x
显示屏直接安装的不同是
点击安装centos 7 ,等完全加载完,出现命令行,然后 cd /dev 中 ls ,会发现 目前u盘的名称(sdb4)
reboot重启设备,重新进到 Install centos 7 ,按e 修改
setparams 'Install CentOS 7'
linuxefi /images/pxeboot/vmlinuz inst.stage2=hd:/dev/sdb4 quiet
initrdefi /images/pxeboot/initrd.img
修改完按ctrl+x
