1.没有ssl，安装之

yum -y install curl nss openssl

2. 升级内核

参考博文[https://blog.csdn.net/lvshuocool/article/details/79540617][https_blog.csdn.net_lvshuocool_article_details_79540617]

1.>导入public key

rpm --import http://www.elrepo.org/RPM-GPG-KEY-elrepo.org  
2.>安装ELRepo到CentOS-6.5中

rpm -ivh http://www.elrepo.org/elrepo-release-6-8.el6.elrepo.noarch.rpm  
3.>安装\*\*kernel-lt（lt=long-term）\*\*

yum --enablerepo=elrepo-kernel install kernel-lt -y  
或者安装kernel-ml（ml=mainline）

yum --enablerepo=elrepo-kernel install kernel-ml -y  
4.>编辑grub.conf文件，修改Grub引导顺序

vim /etc/grub.conf  
\# grub.conf generated by anaconda  
\#  
default=0  
timeout=5  
splashimage=(hd0,0)/grub/splash.xpm.gz  
hiddenmenu  
title CentOS (4.4.121-1.el6.elrepo.x86\_64)  
root (hd0,0)  
kernel /vmlinuz-4.4.121-1.el6.elrepo.x86\_64 ro root=UUID=9955fe5f-5015-4582-a9d5-60fedd85d282 rd\_NO\_LUKS rd\_NO\_LVM LANG=zh\_CN.UTF-8 rd\_NO\_MD SYSFONT=latarcyrheb-sun16 crashkernel=auto KEYBOARDTYPE=pc KEYTABLE=us rd\_NO\_DM rhgb quiet  
initrd /initramfs-4.4.121-1.el6.elrepo.x86\_64.img  
title CentOS (2.6.32-431.el6.x86\_64)  
root (hd0,0)  
kernel /vmlinuz-2.6.32-431.el6.x86\_64 ro root=UUID=9955fe5f-5015-4582-a9d5-60fedd85d282 rd\_NO\_LUKS rd\_NO\_LVM LANG=en\_US.UTF-8 rd\_NO\_MD SYSFONT=latarcyrheb-sun16 crashkernel=auto KEYBOARDTYPE=pc KEYTABLE=us rd\_NO\_DM rhgb quiet  
initrd /initramfs-2.6.32-431.el6.x86\_64.img

确认刚安装好的内核在哪个位置，然后设置default值（从0开始），一般新安装的内核在第一个位置，所以设置default=0

5.>重启，查看内核版本号.

\[root@localhost ~\]\# reboot  
\[root@localhost ~\]\# uname -r  
4.4.121-1.el6.elrepo.x86\_64
