此时系统已经不能正常执行reboot命令重启了，只能强制按电源重启机器。重启之后，原系统已经崩溃，进不去系统了，停在下面的界面：
然后使用RHEL6的光盘引导机器，选择rescue，进入到shell之后提示无法chroot到/mnt/sysimage，无解。
然后重启，用RHEL6安装光盘引导机器，选择Install or Update系统，进入图形后选择update已有系统，失败，如下图。
然后按ctrl+alt+F2切换到第2个console，发现原系统已经被自动挂载到/mnt/sysimage目录，尝试chroot到/mnt/sysimage，由于bash被上面依赖更新了，所以会提示找不到/bin/sh，手动把/mnt/sysimage/usr/bin/sh 拷到 /mnt/sysimage/bin/sh，再次chroot成功。
手工挂载RHEL6的ISO到/mnt/rhel65并cd到Packages目录，强制将上面更新过的几个包更新回到RHEL6的版本：
# rpm --force --nodeps -Uvh [RPM包名] 分别把bash/glibc/glibc-common/glibc-devel/glibc-headers这几个包装回去。
重启系统，发现已经可以正常进入到原系统了，最后使用yum remove把最开始安装的RHEL7的包给remove掉，问题全部解决。
