解決yum install 報錯問題

在虛擬機器上安裝了Centos 6.8 mininal版本 由於網速太慢，用yum安裝老是報超時錯誤 於是打算將yum源換成國內源，安裝網上的教程 安裝過阿里雲和163源 老是報下面的錯誤

Loaded plugins: fastestmirror
Determining fastest mirrors
http://mirrors.163.com/centos/6/os/x86_64/repodata/repomd.xml: [Errno 14] PYCURL ERROR 56 - "Failure when receiving data from the peer"
 

Trying other mirror.
Error: Cannot retrieve repository metadata (repomd.xml) for repository: base. Please verify its path and try again

搜尋了各種辦法都不行，正打算換回原來的備份時又不小心把備份給刪掉了，於是打算重新下載一個CentOS-Base.repo 檔案，這次隨意找了個清華的源，結果卻成功了。我也不清楚什麼原因，希望有知情人可以告知，謝謝了。

更換yum源

牢騷發完了，下面開始正題

首先備份原始檔 CentOS-Base.repo

sudo mv /etc/yum.repos
 
.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.bak 

將新的原始檔上傳到/etc/yum.repos.d 目錄或在改目錄下新建一個檔案 命名為 CentOS-Base.repo
內容為
注意 這是 Centos 6的 其他版本 請點開連結去複製 清華大學映象站

# 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.
