解决方法：

  1. vim /etc/default/grub 文件里去掉 rhgb 参数。
    [[email protected]01 ~/]#vim /etc/default/grub
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR="$(sed ‘s, release .*$,,g‘ /etc/system-release)"
GRUB_DEFAULT=saved
GRUB_DISABLE_SUBMENU=true
GRUB_TERMINAL_OUTPUT="console"
GRUB_CMDLINE_LINUX="crashkernel=auto biosdevname=0 net.ifnames=0 rhgb quiet"   # 删掉 rhgb，其中"rhgb"表示"redhat graphics boot"，就是图形进度条模式
GRUB_DISABLE_RECOVERY="true"
  2. 然后执行 grub2-mkconfig -o /boot/grub2/grub.cfg
    [[email protected]01 ~/]#grub2-mkconfig -o /boot/grub2/grub.cfg
