CentOS7 镜像使用帮助:可以解决yum503报错问题以及没有ifconfig等问题

建议先备份 CentOS-Base.repo

sudo cp /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.bak

然后编辑 /etc/yum.repos.d/CentOS-Base.repo 文件,在 mirrorlist= 开头行前面加 # 注释掉;并将 baseurl= 开头行取消注释(如果被注释的话),把该行内的域名(例如mirror.centos.org)替换为 mirrors.tuna.tsinghua.edu.cn

或者,你也可以直接使用如下内容覆盖掉 /etc/yum.repos.d/CentOS-Base.repo 文件:(未经充分测试)

# 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.
#

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-7

最后,更新软件包缓存

sudo yum makecache

更新yum

yum update

更新net-tools,因为ifconfig在net-tools里面,所以需要安装这个包。

yum install net-tools
