我有 godaddy 的专用服务器。
Linux 信息如下。版本：CentOS 版本 6.9 (Final) 内核：2.6.32-042stab111.11
我已经在服务器上执行了“yum update”，现在 /boot 显示以下文件。

安装的 rpm 显示以下软件包：
kernel-firmware-2.6.32-696.18.7.el6.noarch
dracut-kernel-004-409.el6_8.2.noarch
kernel-headers-2.6.32-696.18.7.el6.x86_64

kernel-2.6.32-696.16.1.el6.x86_64
kernel-2.6.32-696.18.7.el6.x86_64
并重新启动服务器。
但，内核依然只是旧版本。

我以为出了问题，并尝试检查 grub 信息，但服务器上不存在 grub.conf 文件。
我想问两个问题。
如何启动新内核？如何使用 godaddy 专用服务器的 grub.conf？
如果有人知道这个解决方法，请告知我。
谢谢。
