CentOS7.7挂载本地镜像源

第一步：查看 CD/DVD是否 “已连接”

VM中找到该系统，然后鼠标邮件，选择 可以移动设置 > CD/DVD > 设置

需要为已连接状态

第二步：修改配置

vim /etc/fstab

新增如下内容，并保存退出

/dev/cdrom /mnt/cdrom    iso9660  defaults 0  0

第三步：挂载本地镜像

<span style="box-sizing: border-box;padding-right: 0.1px">mount <span style="box-sizing: border-box;color: rgb(0, 0, 204)">-a</span></span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box"></span></span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(170, 85, 0)"># 结果</span></span><br></br><span style="box-sizing: border-box;padding-right: 0.1px">mount: /dev/sr0 is write-protected, mounting read-only</span>

第四步：删除自动生成的yum源

rm -rf /etc/yum.repos.d/*

第五步：创建自定义本地yum源配置

<span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(51, 0, 170)">cd</span> /etc/yum.repos.d</span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box"></span></span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(51, 0, 170)">vim</span> CentOS7.repo</span>

新增如下内容，并保存退出

<span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(170, 85, 0)"># yum的唯一ID</span></span><br></br><span style="box-sizing: border-box;padding-right: 0.1px">[CentOS7]</span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(170, 85, 0)"># 描述信息</span></span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(0, 0, 255)">name</span><span style="box-sizing: border-box;color: rgb(152, 26, 26)">=</span>CentOS-server</span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(170, 85, 0)"># 挂载地址。/mnt为挂载点，前2个//为固定格式，最后一个/表示根目录</span></span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(0, 0, 255)">baseurl</span><span style="box-sizing: border-box;color: rgb(152, 26, 26)">=</span>file:///mnt</span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(170, 85, 0)"># 默认启用</span></span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(0, 0, 255)">enabled</span><span style="box-sizing: border-box;color: rgb(152, 26, 26)">=</span><span style="box-sizing: border-box;color: rgb(17, 102, 68)">1</span></span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(170, 85, 0)"># 取消验证</span></span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(0, 0, 255)">gpgcheck</span><span style="box-sizing: border-box;color: rgb(152, 26, 26)">=</span><span style="box-sizing: border-box;color: rgb(17, 102, 68)">0</span></span>

第六步：清空并生成缓存列表

<span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(170, 85, 0)"># 清空yum缓存</span></span><br></br><span style="box-sizing: border-box;padding-right: 0.1px">yum clean all</span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box"></span></span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(170, 85, 0)"># 生成缓存列表</span></span><br></br><span style="box-sizing: border-box;padding-right: 0.1px">yum list</span>

第七步：验证yum

yum -y install wget

正常安装则配置本地yum完成

我是温新！
