Linux 服务器配置yum私服

>说明:
>1. 测试使用服务器为`Centos7`
>2. 服务器通过访问`192.167.119.200`以代理的方式拉取软件源
>3.`192.167.119.200`使用的私服程序为`nexus`
## 配置方式
### 备份原有源配置
```shell
cp /etc/yum.repos.d/* ./backup
```
### 配置源信息
>根据现有业务场景，主要的源需要定义三个
>- Centos软件源
>- docker-ce 软件源
>- kubernetes 软件源

>编辑CentOS-Base.repo
```shell
cd /etc/yum.repos.d/
vim CentOS-Base.repo
```
>把以下内容复制到文件上
```shell
[nexus]
name=Nexus Yum Repository
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os&infra=$infra

```
>更新yum缓存
```shell
yum clean all # 清除旧缓存
yum makecache  # 生成缓存
yum update # 测试更新
```
>出现以下信息证明，配置成功
