Docker安装Centos

第一步:安装镜像启动之后,修改网络配置

echo “nameserver 8.8.8.8” > /etc/resolv.conf
echo “nameserver 1.1.1.1” >> /etc/resolv.conf

第二步:修改镜像源配置 /etc/yum.repos.d

涉及三个文件 可以提前做好备份

(1)CentOS-Linux-AppStream.repo (2)CentOS-Linux-Extras.repo (3) CentOS-Linux-BaseOS.repo

修改之前

[root@656a44bc29f9 yum.repos.d]# cat CentOS-Linux-BaseOS.repo.bank

[baseos]
name=CentOS Linux $releasever-BaseOSmirrorlist=http://mirrorlist.centos.org/?release=$ releasever&arch=$ basearch&repo=BaseOS&infra=KaTeX parse error: Expected 'EOF', got '#' at position 7: infra #̲baseurl=http://…contentdir/$releasever/BaseOS/$basearch/os/
gpgcheck=1
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-centosofficial

修改之后

[root@656a44bc29f9 yum.repos.d]# cat CentOS-Linux-BaseOS.repo

[baseos]
name=CentOS Linux KaTeX parse error: Expected 'EOF', got '#' at position 21: …sever - BaseOS #̲mirrorlist=http…releasever&arch=KaTeX parse error: Expected 'EOF', got '&' at position 9: basearch&̲repo=BaseOS&inf…infra
baseurl=http://mirrors.aliyun.com/centos/$releasever/BaseOS/$basearch/os/
gpgcheck=1
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-centosofficial

其余两个文件一样.把每一个BaseOS AppStream Extras 换成对应的就行

#清除缓存,重新加载缓存
yum clear all
yum makecache
然后就可以重新下载你要的工具,比如vim naon等
