<p><span style="font-size: 24pt;"><strong>VmShell开源CentOS 7 配置内部YUM源</strong></span>，<span style="color: #ff6600;"><strong>本YUM源每晚凌晨1点自动获取最新的组件依赖提供自动更新，方便企业内网使用该模板</strong></span>，同时VmShell的YUM源服务器在日本，方便国际网络更新，具体方式如下：<br /><strong>1、备份</strong><br />mkdir /etc/yum.repos.d/backup && mv /etc/yum.repos.d/*.repo /etc/yum.repos.d/backup/<br /><strong>2、下载新的</strong> CentOS-Base.repo 到 /etc/yum.repos.d/<br />curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.vmshell.com/repo/CentOS-Base.repo<br />3<strong>、运行 yum clean all && yum makecache && yum -y update && yum -y upgrade 生成缓存并更新依赖</strong><br /><strong>4、运行 yum repolist 查看已经生成缓存</strong></p>
|

<p><br />重要提醒：当然VmShell也将该YUM源模板提供出来用于大家下载给公司企业内网作为yum源使用（<span style="color: #ff0000;"><strong>解决企业内网服务器更新YUM源的问题，仅仅只需要更换IP即可</strong></span>）：<br /><strong>服务器配置：</strong>4C-4GB-50GB (SSD) ，实际模板文件为35GB大小；<br /><strong>服务器系统</strong>：Centos7.9 64bit<br /><strong>服务器用户名</strong>：root<br /><strong>服务器端口</strong>：22<br /><strong>服务器密码</strong>：000000</p>

<p>1、由于CentoS7源停止了更新，阿里源在线更新速度太慢，也缺少第三方yum源，因此基于VmShell国际线路搭建一台yum源服务器满足这一需求，同时网络层面策略只允许此yum源服务器每周日晚限时联网同步阿里云的yum源保持最新。<br />2、准备亚洲服务器用作yum源服务器。<br />3、系统版本：CentOS 7.9<br />实操步骤：<br />一、添加阿里云yum源<br />备份原系统的repo<br />mkdir /etc/yum.repos.d/backup && mv /etc/yum.repos.d/*.repo /etc/yum.repos.d/backup && screen -S centos<br />添加阿里云yum源并缓存（Centos-7.repo是软件仓库配置文件，epel-7.repo是扩展源、提供额外的软件包）<br />curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo && curl -o /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo && yum clean all && yum makecache && yum repolist</p>

|
||
<p>同步阿里云yum源软件包<br />参数-n指下载最新软件包，-p指定目录，指定本地的源--repoid（如果不指定就同步本地服务器所有的源）,下载过程比较久（10个小时左右）<br />reposync -n --repoid=extras --repoid=updates --repoid=base --repoid=epel -p /mirror<br />我们可以输入该命令显示目录文件夹大小: du -sh /mirror/*</p>

<h2>1、备份</h2>
|
||
<p><br />mkdir /etc/yum.repos.d/backup<br />mv /etc/yum.repos.d/*.repo /etc/yum.repos.d/backup/<br /><br /><br /></p>
|
||
<h2>2、下载新的 CentOS-Base.repo 到 /etc/yum.repos.d/</h2>
|
||
<p><br />curl -o /etc/yum.repos.d/CentOS-Base.repo http://23.173.216.66/repo/CentOS-Base.repo<br /><br /><br /></p>
|
||
<h2>3、运行 yum clean all && yum makecache && yum -y update && yum -y upgrade 生成缓存并更新依赖</h2>
|
||
<p><br /><br /><br /></p>
|
||
<h2>4、运行 yum repolist 查看已经生成缓存</h2>

<p><br /><br /><br />EOF<br />注意： 上文中的 http://mirrors.vmshell.com 填写自身yum源服务器的ip地址。<br />七、编写yum源客户端配置文件<br />创建repo文件夹<br />mkdir -p /mirror/repo/<br />###复制粘贴执行,注意：mirrors.vmshell.com需要更改为服务器ip地址。</p>
|
||
<p>cat << EOF > /mirror/repo/CentOS-Base.repo</p>
