将base源epel源同步到本地

环境：centos7

使用的工具：yum-utils createrepo

yum源：这里使用的是清华源，之前使用ali发现失败的太多

epel

注坑1：使用清华的yum源就得使用清华的dns要不然可能没办法解析地址，如果你能解析当我没说

一、yum源准备

1.备份yum源

mkdir mv /etc/yum.repos.d/bak  && mv /etc/yum.repos.d/* mv /etc/yum.repos.d/bak

2.配置清华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地址为清华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.安装工具

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：这里 base 是需要同步的源标签。/usr/local/nginx/htm是同步到的目录。有亿点久1w多个包

3.生成依赖关系

createrepo /usr/local/nginx/htm/base

createrepo /usr/local/nginx/htm/epel

注：

1.base后面别加/

2.记住可能会报有些包错误，去清华开源下载同样的包替换即可

出现以下无报错则成功

[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
已加载插件：fastestmirror

到此base、epel源已经成功同步至本地了，实验不难，就是下载需要消耗大量时间
