Linux学习 (1) 更换Yum源

　　笔者环境为Cent OS 6.9

 

　　1. 备份Yum配置文件

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup

　　2.下载新的CentOS-Base.repo 到/etc/yum.repos.d/

CentOS 5
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-5.repo
CentOS 6
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo
CentOS 7
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

　　3.运行yum makecache生成缓存

yum clean all 
yum makecache
yum update

 

　　4.查看安装路径

[root@LeiCentOS68 data]# rpm -qa | grep traceroute
traceroute-2.0.14-2.el6.x86_64

 

[root@LeiCentOS68 data]# rpm -ql traceroute-2.0.14-2.el6.x86_64
/bin/traceroute
/bin/traceroute6
