报出404的错误
安装好CentOS后，使用yum安装报错_Linux
第一种：更改yum源
原因是没有配置yum源，修改/etc/yum.repos.d/CenOS-Base.repo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.

第二种：删除原有yum文件
如果不行，这样，删除原有的文件：
rm -f /etc/yum.repos.d/CentOS-Base.repo
1.
然后重新下载阿里的：
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
1.
清理缓存：
yum clean all
1.
第三种：删除所有yum文件
ps:如果上述方法没有解决，尝试下面：
删除yum.repos.d目录下所有文件
rm -f /etc/yum.repos.d/*
1.
然后重新下载阿里的：
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
1.
清理缓存：
yum clean all
1.
测试下载安装：
yum install gcc
1.
愿路途漫长，以后莫失莫忘。 愿你不骄不躁，安稳顺心。
