CentOS7 原生系统不能从网上yum源中自动下载依赖包的解决方案

首先备份/etc/yum.repos.d/CentOS-Base.repo


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

下载对应版本repo文件, 放入/etc/yum.repos.d/(操作前请做好相应备份)

CentOS7： http://mirrors.163.com/.help/CentOS7-Base-163.repo

运行以下命令生成缓存

yum clean all

yum makecache

修改以后的 CentOS-Base.repo 文件：

# 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.
