一、为什么要搭建网络yum源？

        为安装虚拟机用中文插件 zhcon，经过网络一番狠狠查找后，有网友推荐用yum安装，所以就配置了网络yum源。下面将详细配置步骤记录下来。

二、网络yum源配置步骤

第一步、虚拟机必须能ping通外网，确保网络畅通

[root@localhost ~]# ping 114.114.114.114    <--能ping通代表网络畅通
PING 114.114.114.114 (114.114.114.114) 56(84) bytes of data.
64 bytes from 114.114.114.114: icmp_seq=1 ttl=128 time=28.6 ms
64 bytes from 114.114.114.114: icmp_seq=2 ttl=128 time=29.4 ms
64 bytes from 114.114.114.114: icmp_seq=3 ttl=128 time=35.9 ms
64 bytes from 114.114.114.114: icmp_seq=4 ttl=128 time=28.6 ms
64 bytes from 114.114.114.114: icmp_seq=5 ttl=128 time=28.1 ms
64 bytes from 114.114.114.114: icmp_seq=6 ttl=128 time=51.2 ms

第二步、备份配置文件

[root@localhost ~]# cd /etc/yum.repos.d/            <--进入配置目录
[root@localhost yum.repos.d]# ls                    <--查看配置文件
CentOS-Base.repo  CentOS-Debuginfo.repo  CentOS-fasttrack.repo  CentOS-Media.repo  CentOS-Vault.repo
[root@localhost yum.repos.d]# cp -a /etc/yum.repos.d/* /tmp/    <--所有配置文件拷贝到 /tmp/ 目录下
[root@localhost yum.repos.d]# ls /tmp                           <--拷贝成功
CentOS-Base.repo       CentOS-fasttrack.repo  yum.log                                   yum_save_tx-2022-04-24-19-04oHS63a.yumtx
CentOS-Base.repo.bak   CentOS-Media.repo      yum_save_tx-2022-04-24-19-017v8IEc.yumtx
CentOS-Debuginfo.repo  CentOS-Vault.repo      yum_save_tx-2022-04-24-19-03R5u8X8.yumtx
[root@localhost yum.repos.d]# 

第三步、下载yum源

[root@localhost yum.repos.d]# wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo

第四步、修改yum源地址 

1. http://mirrors.aliyun.com/centos/ 修改成 https://vault.centos.org/6.8/os/x86_64/

2. http://mirrors.aliyun.com/ 修改成 http://vault.centos.org/

3. 修改结果如下面代码

[root@localhost yum.repos.d]# vi CentOS-Base.repo 

  1 # CentOS-Base.repo
  2 #
  3 # The mirror system uses the connecting IP address of the client and the
  4 # update status of each mirror to pick mirrors that are updated to and
  5 # geographically close to the client.  You should use this for CentOS updates
  6 # unless you are manually picking other mirrors.
  7 #
  8 # If the mirrorlist= does not work for you, as a fall back you can try the 
  9 # remarked out baseurl= line instead.
 10 #
 11 #

第五步、 释放yum源缓存

yum clean all

第六步、重新建立yum缓存

yum makecache

第七步、建立缓存成功后，查看yum源列表

yum list

        至此，出现yum列表即证明网络yum源配置成功。

三、小结
