centos6.4配置网络yum源

参考于：

http://mirrors.aliyun.com/help/centos?spm=5176.bbsr150321.0.0.d6ykiD

1、备份原文件

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo_bak@H_403_11@

2、下载新的repo文件

CentOS 5

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-5.repo @H_403_11@ 

  CentOS 6 
 
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo@H_403_11@ 
 
 
   CentOS 7 
  
 wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo@H_403_11@ 
 
 
 

  网易源centos6 
 
 
 wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.163.com/.help/CentOS6-Base-163.repo@H_403_11@ 
 
 
 [root@rac1 yum.repos.d]# wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.163.com/.help/CentOS6-Base-163.repo
--2017-10-14 23:18:31--  http://mirrors.163.com/.help/CentOS6-Base-163.repo

100%[=========================================================>] 2,006       --.-K/s   in 0.001s  

2017-10-14 23:18:31 (1.90 MB/s) - 已保存 “/etc/yum.repos.d/CentOS-Base.repo” [2006/2006])
@H_403_11@ 
 
 
 
 
 
 
 
 
 
 
 

  3、如果报域名解析失败： 
 
 
 [root@RAC01 yum.repos.d]# wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo 
--2017-10-14 01:22:16--  http://mirrors.aliyun.com/repo/Centos-6.repo
正在解析主机 mirrors.aliyun.com... 失败：域名解析暂时失败。
wget: 无法解析主机地址 “mirrors.aliyun.com”@H_403_11@ 
 
 
 

  4、新增dns域名地址 
 

  新增下面一条内容： 
 
 
 [root@RAC01 yum.repos.d]# vi /etc/resolv.conf @H_403_11@ 
 nameserver 8.8.8.8@H_403_11@ 
 
 
 
 
 

  5、生成缓存 
 
 
 [root@RAC01 yum.repos.d]# yum makecache
