linux——yum源報錯

linux下新申請了臺服務器，可是因爲yum源的問題，浪費了很長的時間，具體報錯與解決方案以下

#yum list 

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

解決：

將/etc/yum.repos.d下的文件移動到一個新建的文件目錄下，

下載新的CentOS-Base.repo到/etc/yum.repos.d/   （其實就是講yum源更改成阿里雲的yum源，操做以下）

1）centos5.*的下載鏈接：
[root@bastion-IDC yum.repos.d]# wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-5.repo

2）centos6.*的下載鏈接：
[root@bastion-IDC yum.repos.d]# wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo

# 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.

3）centos7.*的下載鏈接：
[root@bastion-IDC yum.repos.d]# wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

而後執行如下命令：

yum  list      &&  yum  makecache
