1. 查询服务器的系统版本
[rootnys yum.repos.d]# rpm -qi centos-release

2. 更换yum源
进入yum配置文件目录
cd /etc/yum.repos.d[rootnys yum.repos.d]# ll
total 60
drwxr-xr-x 2 root root 4096 Oct 17 2017 backup
-rw-r--r-- 1 root root 1901 Jan 5 15:35 CentOS-Base.repo #此文件为yum使用的源配置

-rw-r--r-- 1 root root 957 Nov 5 2012 epel.repo.rpmnew
-rw-r--r-- 1 root root 1056 Nov 5 2012 epel-testing.repo
-rw-r--r-- 1 root root 206 Aug 20 17:58 influxdb.repo确保yum源可访问此处用的163源
http://mirrors.163.com/centos/6.10/
可以查看网易的源说明
http://mirrors.163.com/.help/
下载对应版本的163源
wget http://mirrors.163.com/.help/CentOS6-Base-163.repo
替换源文件到Base
sudo cp CentOS6-Base-163.repo CentOS-Base.repo
更换Base文件中的路径为指定版本号

# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client. You should use this for CentOS updates
# unless you are manually picking other mirrors.

# remarked out baseurl line instead.

* 需要将$releasever替换为当前系统版本号6.10对应可访问的163源路径
http://mirrors.163.com/centos/6.10/
使用vim替换
:%s/$releasever/6.10/g
仅展示部分替换后的文件内容

#重置缓存
yum makecache其它可参考执行的命令
#检查可以更新的软件包
yum check-update #更新所有的软件包
yum update #更新特定的软件包
yum update kernel #大规模的升级
yum upgrade#清楚缓存中rpm包文件
yum clean packages #清楚缓存中rpm的头文件
yum clean headers #清除缓存中旧的头文件
yum clean old headers #清除缓存中旧的rpm头文件和包文件
yum clean all如果不成功还原为默认源配置文件
CentOS-Base.repo 源文件内容需要将版本6改为7因为6版本repomd.xml文件已经没有了只能从7版本开始
http://mirror.centos.org/centos/7/os/x86_64/repodata/
[rootnys yum.repos.d]# cat CentOS-Base.repo
