環境：centos7
使用的工具：yum-utils createrepo
yum源：這里使用的是清華源，之前使用ali發現失敗的太多
epel

注坑1：使用清華的yum源就得使用清華的dns要不然可能沒辦法解析地址，如果你能解析當我沒說
一、yum源准備
1.備份yum源
mkdir mv /etc/yum.repos.d/bak && mv /etc/yum.repos.d/* mv /etc/yum.repos.d/bak
2.配置清華yum源
cat /etc/yum.repos.d/CentOS-Base.repo
[base] name=qinghua baseurl=http://mirrors.tuna.tsinghua.edu.cn/centos/7/os/x86_64/ gpgcheck=0 enable=1
cat /etc/yum.repos.d/epel.repo
[epel] name=Extra Packages for Enterprise Linux 7 - $basearch baseurl=https://mirrors.tuna.tsinghua.edu.cn/epel/7/$basearch #mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-7&arch=$basearch failovermethod=priority enabled=1 gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7 [epel-debuginfo] name=Extra Packages for Enterprise Linux 7 - $basearch - Debug baseurl=https://mirrors.tuna.tsinghua.edu.cn/epel/7/$basearch/debug #mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-debug-7&arch=$basearch failovermethod=priority enabled=0 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7 gpgcheck=1 [epel-source] name=Extra Packages for Enterprise Linux 7 - $basearch - Source baseurl=https://mirrors.tuna.tsinghua.edu.cn/epel/7/SRPMS #mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-source-7&arch=$basearch failovermethod=priority enabled=0 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7 gpgcheck=1
3.修改dns地址為清華dns
sed -i -r "s/DNS1=.*$/DNS1=101.6.6.6/g" /etc/sysconfig/network-scripts/ifcfg-eth0
systemctl restart network
二、同步源
1.安裝工具
yum -y install yum-utils createrepo
2.同步yum源到本地
reposync -r base -p /usr/local/nginx/htm
reposync -r epel -p /usr/local/nginx/htm
注：這里 base 是需要同步的源標簽。/usr/local/nginx/htm是同步到的目錄。有億點久1w多個包
3.生成依賴關系
createrepo /usr/local/nginx/htm/base
createrepo /usr/local/nginx/htm/epel
注：
1.base后面別加/
2.記住可能會報有些包錯誤，去清華開源下載同樣的包替換即可
出現以下無報錯則成功
[root@recall-2 yum.repos.d]# createrepo /usr/local/nginx/htm/base

三、配置yum
配置base源
[root@yum yum.repos.d]# cat /etc/yum.repos.d/CentOS-Base.repo
[base]
name=qinghua
baseurl=file:///usr/local/nginx/htm/base/
gpgcheck=0
enable=1
配置epel源
[root@yum yum.repos.d]# cat /etc/yum.repos.d/epel-7.repo
[epel]
name=myepel
baseurl=file:///usr/local/nginx/htm/epel
enabled=1
gpgcheck=0
[root@yum yum.repos.d]# yum clean all
[root@yum yum.repos.d]# yum repolist
已加載插件：fastestmirror

到此base、epel源已經成功同步至本地了，實驗不難，就是下載需要消耗大量時間
