更新centos内核

查看当前内核版本

[root@localhost ~]# more /etc/issue
CentOS release 6.5 (Final)
Kernel \r on an \m
[root@localhost ~]# uname -a
Linux localhost.localdomain 2.6.32-431.el6.x86_64 #1 SMP Fri Nov 22 03:15:09 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

发现低于3.1.0,更新内核版本到3.1

导入Public key

rpm --import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org

提示如下报错：

 curl: (35) SSL connect error

解决方法：升级网络安全服务即可。

 yum update nss

安装ELRepo到CentOS

rpm -Uvh http://www.elrepo.org/elrepo-release-6-6.el6.elrepo.noarch.rpm

报错:

curl: (22) The requested URL returned error: 404 Not Found
error: skipping http://www.elrepo.org/elrepo-release-6-6.el6.elrepo.noarch.rpm - transfer failed

解决:
这表示对应的URL已经不存在，需要重新找EPEL的版本，请前往 http://elrepo.org/tiki/tiki-index.php
更新为:

rpm -Uvh https://www.elrepo.org/elrepo-release-6-8.el6.elrepo.noarch.rpm

yum --enablerepo=elrepo-kernel install kernel-lt -y
