安装yum-utils工具。

yum install yum-utils

查询系统中已经安装的内核。

# rpm -q kernel
kernel-2.6.32-358.el6.x86_64
kernel-2.6.32-696.18.7.el6.x86_64
kernel-2.6.32-696.30.1.el6.x86_64

查询当前系统的内核。

# uname -a
Linux hqrhlprdrep01 2.6.32-696.30.1.el6.x86_64 #1 SMP Fri May 18 11:50:44 EDT 2018 x86_64 x86_64 x86_64 GNU/Linux

删除旧内核，只保留一个内核。
