有两种办法: 1.安装yum-fastestmirror可以自动选择最快的镜像下载
2.更改下载镜像地址,选择国内的镜像地址下载 备注:如果安装了 yum-fastestmirror 的话,由于是动态的选择镜像地址,修改后的镜像地址可能会无效。
1.下载 yum-fastestmirror: yum install yum-plugin-fastestmirror 2.国内主要开源的开源镜像站点应该是网易和阿里云了。下面分别记录替换未阿里云和网易的方法: 一、修改CentOS默认yum源为mirrors.aliyun.com
1、首先备份系统自带的yum源配置文件 /etc/yum.repos.d/CentOS-Base.repo mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup2、进入yum源配置文件所在的文件夹 cd /etc/yum.repos.d/3、下载aliyun的yum源配置文件到/etc/yum.repos.d/ CentOS 7: wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repoCentOS 6: wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repoCentOS 5: wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-5.repo4、运行yum makecache生成缓存 yum makecache5、更新系统 yum -y update二、修改CentOS默认yum源为mirrors.163.com
1、首先备份系统自带的yum源配置文件 /etc/yum.repos.d/CentOS-Base.repo mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup2、进入yum源配置文件所在的文件夹 cd /etc/yum.repos.d/3、下载163的yum源配置文件到/etc/yum.repos.d/ CentOS 7: wget http://mirrors.163.com/.help/CentOS7-Base-163.repoCentOS 6: wget http://mirrors.163.com/.help/CentOS6-Base-163.repoCentOS 5: wget http://mirrors.163.com/.help/CentOS5-Base-163.repo4、运行yum makecache生成缓存 yum makecache5、更新系统 yum -y update
