一、搭建本地yum源 1、将系统镜像复制到空间较大的目录 [root@localhost ~]# mv CentOS-7.9-x86_64-DVD-2009.iso /home/ 2、创建挂载目录并挂载系统镜像 [root@localhost ~]# cd /home [root@localhost home]# mkdir /mnt/iso [root@localhost home]# mount -o loop CentOS-7.9-x86_64-DVD-2009.iso /mnt/iso mount: /dev/loop0 写保护，将以只读方式挂载 [root@localhost home]# ls /mnt/iso CentOS_BuildTag EFI EULA GPL images isolinux LiveOS Packages repodata RPM-GPG-KEY-CentOS-7 RPM-GPG-KEY-CentOS-Testing-7 TRANS.TBL 3、备份原有的yum源信息并修改配置本地yum源信息 [root@localhost home]# cd /etc/yum.repos.d/ [root@localhost yum.repos.d]# mkdir ./bak [root@localhost yum.repos.d]# mv ./*.repo ./bak/ [root@localhost yum.repos.d]# cp ./bak/CentOS-Media.repo . [root@localhost yum.repos.d]# vi CentOS-Media.repo

CentOS-Media.repo

This repo can be used with mounted DVD media, verify the mount point for

CentOS-7. You can use this repo and yum to install items directly off the

DVD ISO that we release.

To use this repo, put in your DVD and use it with the other repos too:

yum --enablerepo=c7-media [command]

or for ONLY the media repo, do this:

yum --disablerepo=* --enablerepo=c7-media [command]

[c7-media] name=CentOS-$releasever - Media baseurl=file:///media/CentOS/ file:///mnt/iso <--此处修改为镜像挂载路径 file:///media/cdrecorder/ gpgcheck=1 enabled=1 <--此处将0改为1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7 4、清理并重新读取yum源信息 [root@localhost yum.repos.d]# yum clean all 已加载插件：fastestmirror, langpacks 正在清理软件源： c7-media Cleaning up list of fastest mirrors [root@localhost yum.repos.d]# yum repolist 二、搭建局域网yum源 1、安装Http服务和xml生成工具，由于安装系统时已经顺便安装了相应的安装包，所以此处无须再进行安装。 [root@localhost ~]# yum install -y httpd createrepo 已加载插件：fastestmirror, langpacks Loading mirror speeds from cached hostfile

c7-media: file:///mnt/iso/repodata/repomd.xml: [Errno 14] curl#37 - "Couldn't open file /mnt/iso/repodata/repomd.xml" 正在尝试其它镜像。 file:///media/cdrecorder/repodata/repomd.xml: [Errno 14] curl#37 - "Couldn't open file /media/cdrecorder/repodata/repomd.xml" 正在尝试其它镜像。 file:///media/CentOS/repodata/repomd.xml: [Errno 14] curl#37 - "Couldn't open file /media/CentOS/repodata/repomd.xml" 正在尝试其它镜像。软件包 httpd-2.4.6-95.el7.centos.x86_64 已安装并且是最新版本软件包 createrepo-0.9.9-28.el7.noarch 已安装并且是最新版本无须任何处理 2、新建存放yum源文件的目录并将相关文件复制进去 [root@localhost ~]# mkdir -p /home/data/yum.repo/centos/7/os/x86_64/Packages [root@localhost ~]# mkdir -p /home/data/yum.repo/centos/7/updates/x86_64/Packages [root@localhost ~]# mkdir -p /home/data/yum.repo/tools/ [root@localhost ~]# cp -R /mnt/iso/Packages/* /home/data/yum.repo/centos/7/os/x86_64/Packages/ [root@localhost ~]# cp -R /mnt/iso/repodata /home/data/yum.repo/centos/7/os/x86_64 [root@localhost ~]# cp -R /mnt/iso/repodata /home/data/yum.repo/centos/7/updates/x86_64 [root@localhost ~]# cp -R /mnt/iso/repodata /home/data/yum.repo/tools [root@localhost ~]# cp -R /mnt/iso/RPM-GPG-KEY-CentOS-7 /home/data/yum.repo/ 3、http服务调整查看httpd服务状态 [root@localhost home]# service httpd status Redirecting to /bin/systemctl status httpd.service ● httpd.service - The Apache HTTP Server Loaded: loaded (/usr/lib/systemd/system/httpd.service; disabled; vendor preset: disabled) Active: inactive (dead) Docs: man:httpd(8) man:apachectl(8) 删除默认的html文件夹 [root@localhost home]# rm -rf /var/www/html 创建yum源文件目录到网站目录的软链接 [root@localhost home]# ln -s /home/data/yum.repo /var/www/html 启动http服务并查看服务状态 [root@localhost home]# service httpd start Redirecting to /bin/systemctl start httpd.service [root@localhost home]# service httpd status Redirecting to /bin/systemctl status httpd.service ● httpd.service - The Apache HTTP Server Loaded: loaded (/usr/lib/systemd/system/httpd.service; disabled; vendor preset: disabled) Active: active (running) since 五 2022-02-25 11:02:04 CST; 14s ago Docs: man:httpd(8) man:apachectl(8) Main PID: 16291 (httpd) Status: "Total requests: 0; Current requests/sec: 0; Current traffic: 0 B/sec" Tasks: 7 CGroup: /system.slice/httpd.service ├─16291 /usr/sbin/httpd -DFOREGROUND ├─16294 /usr/sbin/httpd -DFOREGROUND ├─16295 /usr/sbin/httpd -DFOREGROUND ├─16296 /usr/sbin/httpd -DFOREGROUND ├─16297 /usr/sbin/httpd -DFOREGROUND ├─16298 /usr/sbin/httpd -DFOREGROUND └─16299 /usr/sbin/httpd -DFOREGROUND

[root@localhost yum.repos.d]# vi CentOS-Base.repo

CentOS-Base.repo

The mirror system uses the connecting IP address of the client and the

update status of each mirror to pick mirrors that are updated to and

geographically close to the client. You should use this for CentOS updates

unless you are manually picking other mirrors.

If the mirrorlist= does not work for you, as a fall back you can try the

remarked out baseurl= line instead.
