Centos7配置本地yum源
1、基于iso鏡像的centos源
1.1 準備iso
<span style="color:#000000"><span style="background-color:#ffffff"><code class="language-bash"><span style="color:#008000"># 首先看自己使用的linux服務器內核版本</span>
[root@centos-2009 home]<span style="color:#008000"># cat /etc/redhat-release</span>
CentOS Linux release 7.9.2009 (Core)<span style="color:#008000"># 下載對應版本的linux鏡像</span>
<span style="color:#008000"># 我這里用的時清華大學的開源網站</span>
https://mirrors.tuna.tsinghua.edu.cn/centos/7/isos/x86_64/
<span style="color:#008000"># 下載CentOS-7-x86_64-DVD-2009.iso標準版，并傳到 /home 路徑下</span>
</code></span></span>1.2 掛載iso
<span style="color:#000000"><span style="background-color:#ffffff"><code class="language-bash"><span style="color:#008000">#嘗試過直接把iso鏡像放到/media/CentOS/路徑下而不掛載導致無法獲取yum源文件</span>
<span style="color:#008000">#掛載iso文件</span>
[root@centos-2009 /]<span style="color:#008000"># mkdir -p /mnt/centos</span>
[root@centos-2009 /]<span style="color:#008000"># mount -o loop /home/CentOS-7-x86_64-DVD-2009.iso /mnt/centos/</span>
mount: /dev/loop0 寫保護，將以只讀方式掛載<span style="color:#008000">#查看iso鏡像內含的文件</span>
[root@centos-2009 /]<span style="color:#008000"># ls /mnt/centos/</span>

yum clean all
<span style="color:#008000">#顯示已配置的源</span>
yum repolist
<span style="color:#008000">#yum安裝一個插件試試，如果安裝成功，則yum掛載成功，原來的iso鏡像可以刪除了</span>
</code></span></span>1.3 備份原yum源的配置文件
<span style="color:#000000"><span style="background-color:#ffffff"><code class="language-bash"><span style="color:#008000"># 進入yum源的配置文件處</span>
<span style="color:#0000ff">cd</span> /etc/yum.repos.d/
<span style="color:#008000"># 將所有文件備份，其中CentOS-Base.repo是默認使用的yum源配置文件，CentOS-Media.repo是本地的yum源配置文件</span>
<span style="color:#0000ff">mkdir</span> -p /etc/yum.repos.d/repo.bak
<span style="color:#0000ff">mv</span> ./*.repo repo.bak/
<span style="color:#008000"># 復制一份CentOS-Media.repo</span>
<span style="color:#0000ff">cp</span> ./repo.bak/CentOS-Media.repo ./
</code></span></span>1.4 修改yum源的配置文件
修改?CentOS-Media.repo使其啟用
<span style="color:#000000"><span style="background-color:#ffffff"><code class="language-bash">vim /etc/yum.repos.d/CentOS-Media.repo
</code></span></span>修改內容如下
<span style="color:#000000"><span style="background-color:#ffffff"><code class="language-bash">[Centos7]
name=Centos7 - Media
baseurl=file:///mnt/centos
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7
</code></span></span>文件注釋，不可復制repo不識別#
<span style="color:#000000"><span style="background-color:#ffffff"><code class="language-bash">[Centos7] <span style="color:#008000"># 這個是本源的名字（隨便，不可重復）</span>
name=Centos7 - Media <span style="color:#008000"># 名字（隨便）</span>
baseurl=file:///mnt/centos <span style="color:#008000"># 上方步驟復制鏡像所創建的目錄</span>
enabled=1 <span style="color:#008000"># yum源是否啟用 1-啟用 0-不啟用</span>
gpgcheck=1 <span style="color:#008000"># 安全檢測 1-啟用 0-不啟用</span>
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7
</code></span></span>1.5 更新yum源配置
<span style="color:#000000"><span style="background-color:#ffffff"><code class="language-bash"><span style="color:#008000"># 清除原來的yum緩存</span>
yum clean all
<span style="color:#008000"># 建立元數據緩存</span>
yum makecache
<span style="color:#008000"># 顯示已配置的源</span>
yum repolist
<span style="color:#008000"># 有如下信息表示yum源制作成功，包的yum源文件名字都變成了Centos7</span>
<span style="color:#008000"># 安裝基礎工具包</span>
