将yum的目标服务器更改为中国大陆服务器镜像

将yum的目标服务器更改为中国大陆服务器镜像

修改/etc/yum.repos.d/CentOS-Base.repo，将镜象站点地址改为在中国的镜象站点地址。不然我们通过yum安装软件速度会比较慢。
以下的URL地址我都验证过了在当前完全可以下载,而且速度挺快.
mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.bak
vi /etc/yum.repos.d/CentOS-Base.repo

# CentOS-Base.repo## This file uses a new mirrorlist system developed by Lance Davis for CentOS.# 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-$releasever - Basebaseurl=http://mirror.be10.com/centos/$releasever/os/$basearch/http://ftp.iasi.roedu.net/mirrors/centos.org/$releasever/os/$basearch/http://ftp.ncnu.edu.tw/Linux/CentOS/$releasever/os/$basearch/http://ftp.hostrino.com/pub/centos/gpgcheck=1gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-centos4#released updates[update]name=CentOS-$releasever - Updatesbaseurl=http://mirror.be10.com/centos/$releasever/os/$basearch/http://ftp.iasi.roedu.net/mirrors/centos.org/$releasever/os/$basearch/http://ftp.ncnu.edu.tw/Linux/CentOS/$releasever/os/$basearch/http://ftp.hostrino.com/pub/centos/gpgcheck=1gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-centos4#packages used/produced in the build but not released[addons]name=CentOS-$releasever - Addonsbaseurl=http://mirror.be10.com/centos/$releasever/os/$basearch/http://ftp.iasi.roedu.net/mirrors/centos.org/$releasever/os/$basearch/http://ftp.ncnu.edu.tw/Linux/CentOS/$releasever/os/$basearch/http://ftp.hostrino.com/pub/centos/gpgcheck=1gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-centos4#additional packages that may be useful[extras]name=CentOS-$releasever - Extrasbaseurl=http://mirror.be10.com/centos/$releasever/os/$basearch/http://ftp.iasi.roedu.net/mirrors/centos.org/$releasever/os/$basearch/http://ftp.ncnu.edu.tw/Linux/CentOS/$releasever/os/$basearch/http://ftp.hostrino.com/pub/centos/gpgcheck=1gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-centos4#additional packages that extend functionality of existing packages[centosplus]name=CentOS-$releasever - Plusbaseurl=http://mirror.centos.org/centos/$releasever/centosplus/$basearch/gpgcheck=1enabled=0gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-centos4#contrib - packages by Centos Users[contrib]name=CentOS-$releasever - Contribbaseurl=http://mirror.centos.org/centos/$releasever/contrib/$basearch/gpgcheck=1enabled=0gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-centos4
