CentOS7同步阿里云镜像rpm包并自建本地yum仓库
系统环境

系统环境
# cat /etc/centos-release
CentOS Linux release 7.6.1810 (Core)
# uname -r
3.10.0-957.el7.x86_64
# ip a |awk 'NR==9{print $2}'|awk -F '/' '{print $1}'
10.0.0.100
修改yum源为阿里云源
备份系统自带的yum源
# tar -zcvf CentOS-bk.tar.gz /etc/yum.repos.d/CentOS-*
修改yum源
# wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
# wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
或者
# curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
# curl -o /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
检验阿里云源是否正常
# yum repolist
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
* base: mirrors.aliyun.com

* updates: mirrors.aliyun.com
#仓库标识仓库名称状态

安装相关软件
# yum install -y wget make cmake gcc gcc-c++ pcre-devel zlib-devel openssl openssl-devel createrepo yum-utils
yum-utils：reposync同步工具
createrepo：编辑yum库工具
plugin-priorities：控制yum源更新优先级工具，这个工具可以用来控制进行yum源检索的先后顺序，建议可以用在client端。
注：由于很多人喜欢最小化安装，上边软件是一些常用环境。
根据源标识同步源到本地目录
创建本地目录
#mkdir /mirror/REPO
同步到本地目录
# reposync -p /mirror/REPO
注：不用担心没有创建相关目录，系统自动创建相关目录，并下载，时间较长请耐心等待。
可以用 repo -r --repoid=repoid指定要查询的repo id，可以指定多个（# reposync -r base -p /mirror #这里同步base目录到本地）
更新新的rpm包
# reposync -np /mirror/REOP
创建索引
# createrepo -po /mirror/REPO/base/ /mirror/REPO/base/
# createrepo -po /mirror/REPO/extras/ /mirror/REOP/extras/
# createrepo -po /mirror/REPO/updates/ /mirror/REOP/updates/
# createrepo -po /mirror/REPO/epel/ /mirror/REPO/epel/
更新源数据
# createrepo --update /mirror/REPO/base
# createrepo --update /mirror/REPO/extras
# createrepo --update /mirror/REPO/updates
# createrepo --update /mirror/REPO/epel
创建定时任务脚本
#vim /mirror/script/centos_yum_update.sh
#!/bin/bash
echo 'Updating Aliyum Source'
DATETIME=`date +%F_%T`
exec > /var/log/aliyumrepo_$DATETIME.log
reposync -np /mirror
if [ $? -eq 0 ];then
createrepo --update /mirror/REPO/base
createrepo --update /mirror/REPO/extras
createrepo --update /mirror/REPO/updates
createrepo --update /mirror/REPO/epel
echo "SUCESS: $DATETIME aliyum_yum update successful"
else
echo "ERROR: $DATETIME aliyum_yum update failed"
fi
将脚本加入到定时任务中
# crontab -e
# Updating Aliyum Source
00 13 * * 6 [ $(date +%d) -eq $(cal | awk 'NR==3{print $NF}') ] && /bin/bash /mirror/script/centos_yum_update.sh
每月第一个周六的13点更新阿里云yum源
安装nginx开启目录权限保证本地机器可以直接本地yum源
创建运行账户
groupadd www
useradd -r -g nginx -s /bin/false -M www
# yum install nginx -y
server {
listen 80;
server_name localhost;
root /mirror/REPO;
autoindex on;
autoindex_exact_size off;
autoindex_localtime on;
charset utf-8,gbk;
index index.html;
}
在客户端修改yum源，并指向本地搭建的yum源主机
注：搭建好后yum安装速度并没有想象中的那么快，安装时解决依赖速度也很慢。
