文章讲述了在CenOS6.2环境中遇到yum源问题，通过备份原yum源文件、下载阿里云镜像并替换源配置、清理缓存和重新生成缓存，最终成功安装gcc的过程。

环境CenOS

[root@hncuc ~]# cat /etc/issue
CentOS release 6.2 (Final)
Kernel \r on an \m

安装gcc的时候提示没有包

[root@hncuc ~]# sudo yum install gcc  gcc-c++ libstdc++-devel
Loaded plugins: refresh-packagekit, security
Setting up Install Process
No package gcc available.
No package gcc-c++ available.
Nothing to do

设置阿里云镜像
参考centos6 yum源失效的最新操作方式，解决：[Errno 14] PYCURL ERROR 22
1、备份

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup

在这里插入图片描述
2、下载新文件

wget --no-check-certificate -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-6.repo

在这里插入图片描述

文件内容如下：

# 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.
