CentOS6 yum install wget失败

使用CentOS 6.1 运行 yum -y install wget 安装 wget 时报错失败了，于是百度谷歌搜索了一大堆，尝试之后都不行，之后发现直接替换 repo 文件就能搞定

步骤如下：

1、cd /etc/yum.repos.d

2、更改CentOS-Base.repo里的内容

vi CentOS-Base.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、更新 yum

yum clean all

yum makecache

完成以上步骤，即可正常安装 wget
