正在尝试其它镜像。
To address this issue please refer to the below wiki article
报出404的错误
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.
#

name=CentOS-$releasever - Base
mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os&infra=$infra
#baseurl=http://mirror.centos.org/centos/$releasever/os/$basearch/

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
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
清理缓存:
yum clean all
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/*
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
清理缓存:
yum clean all
测试下载安装:
yum install gcc
愿路途漫长,以后莫失莫忘。 愿你不骄不躁,安稳顺心。
