How to build a private yum source

前言

yum 主要用于自动安装、升级rpm软件包,它能自动查找并解决rpm包之间的依赖关系.要成功的使用 yum 工具安装更新软件或系统,就需要有一个包含各种rpm软件包的repository（软件仓库）,这个软件仓库我们习惯称为 yum源.For machines that can access the public network environment,The public network can be configured quicklyyum源,But for private environments,When the machine cannot access the external network,需要安装各种lib库,devel when the base is dependent,没有yumThe source is an extremely painful thing.

This article describes how to set up privateyum源.

一 Main server side configuration

1.1 创建目录

mkdir -p /data/yum/ky/x86_64/

1.2 安装createrepo软件：

yum -y install createrepo
createrepo -pdo /data/yum/ky/x86_64/ /data/yum/ky/x86_64/

1.3 提供http服务,It is convenient to use on the intranet

cd /data/yum/ky/x86_64/
python -m SimpleHTTPServer 5901 &>/dev/null &

1.4 上传yum 安装包到目录

The current one can be used hereyum Download the configuration belowrpm 包 但是不安装.比如

yumdownloader openssl-devel nginx libaio-devel mariadb

1.5 Configure the machine to use thisyum源

### 编辑 poc 安装使用的yum源
vim ky_poc.repo

[ky_poc] # 指定使用 ky_poc 库
name=Server
baseurl=http://127.0.0.1:5888/ #yum仓库IP 端口,pythonSpecify a different port when starting the service
enable=1    # 启用yum
gpgcheck=0 #Do not check checkgpg

1.6 更新索引

createrepo --update /data/yum/ky/x86_64

二 客户端配置

2.1 配置yum config

### backup otheryum 配置文件,如果有的话
cd /etc/yum.repos.d/
mkdir yum_bak
mv * yum_bak

编辑 poc 安装使用的yum源

vim ky_poc.repo

[ky_poc] # 指定使用 ky_poc 库
name=Server
baseurl=http://The machine where the warehouse is locatedip:5888/ #yum仓库IP 端口,pythonSpecify a different port when starting the service
enable=1    # 启用yum
gpgcheck=0  #Do not check checkgpg

2.2 Access private on the client sideyum 源

yum clean metadata dbcache

yum --enablerepo=ky_poc --disablerepo=base,updates,kubernetes,extras,epel,docker-ce-stable list

至此,一个yumThe source server is configured to use.Of course there are other official actions other than regular syncrpm 包到本地,保持本地的yumThe source is the latest state.
