CentOS修改yum更新源

平时在安装或更新CentOS软件时，yum方式是最简单方便的，而系统默认到yum更新源地址不稳定，所以需要对更新源地址进行修改，国内一般用163比较快。yum更新源配置文件：/etc/yum.repos.d/CentOS-Base.repo1. 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.bak2. 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.
#
