4. 生成grub啟動菜單
[root@CentOS7 network-scripts]# grub2-mkconfig -o /boot/grub2/grub.cfg Generating grub configuration file ... Found linux image: /boot/vmlinuz-3.10.0-327.el7.x86_64 Found initrd image: /boot/initramfs-3.10.0-327.el7.x86_64.img Found linux image: /boot/vmlinuz-0-rescue-4860b79d6cd240788b962a1dbdef488d Found initrd image: /boot/initramfs-0-rescue-4860b79d6cd240788b962a1dbdef488d.img done [root@CentOS7 network-scripts]#
