1. 在修改前先备份该文件
cp /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.bak
2. 修改更新源配置文件（CentOS6地址，其他版本类似）
vim打开配置文件：
vim /etc/yum.repos.d/CentOS-Base.repo
复制以下内容粘贴到配置文件中进行：
# CentOS-Base.repo # # The mirror system uses the connecting IP address of the client and the # 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. # # If the mirrorlist= does not work for you, as a fall back you can try the # remarked out baseurl= line instead. # # [base] name=CentOS-$releasever - Base baseurl=http://mirrors.oschina.com/centos/$releasever/os/$basearch/ gpgcheck=1 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6 [updates] name=CentOS-$releasever - Updates baseurl=http://mirrors.oschina.com/centos/$releasever/updates/$basearch/ gpgcheck=1 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6 [addons] name=CentOS-$releasever - Addons baseurl=http://mirrors.oschina.com/centos/$releasever/addons/$basearch/ gpgcheck=1 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6 [extras] name=CentOS-$releasever - Extras baseurl=http://mirrors.oschina.com/centos/$releasever/extras/$basearch/ gpgcheck=1 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6 [centosplus] name=CentOS-$releasever - Plus baseurl=http://mirrors.oschina.com/centos/$releasever/centosplus/$basearch/ gpgcheck=1 enabled=0 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6
最后保存配置文件。
3. 更新yum源配置
yum update
（如果不愿更新软件，选择N即可）
