CentOS 添加本地yum源

1 创建保存RPM包的路径：

　　mkdir -p /share/CentOS/7/local/x86_64/RPMS　　

2 安装createrepo工具

　　yum install createrepo

3 把RPM包拷贝到 /share/CentOS/7/local/x86_64//RPMS下，并更改目录权限

　　mv  *.rpm /share/CentOS/7/local/x86_64/RPMS

       chown -R root.root /share/CentOS/7/local

       chmod -R o-w+r /share/CentOS/7/local

4 使用 createrepo 创建元数据

　　createrepo /share/CentOS/7/local/x86_64

5 更改yum 配置文件

　　[local]

       name=CentOS-$releasever - local packages for $basearch

       baseurl=file:///share/CentOS/$releasever/local/$basearch

　　enabled=1

　　gpgcheck=0

　　protect=1

 6 更新yum缓存

　　yum clean all

　　yum makecache
