centos7下使用光盘镜像作为软件yum源

使用光盘镜像作为软件yum源：

[1]上传centos7光盘镜像到/usr/local/src目录下；（工具Xftp）

[2]挂载系统文件

mkdir /media/cdrom # 习惯用这个目录名称了；

cd /usr/local/src

CentOS-7.0-1406-x86_64-DVD.iso

# mount -t iso9660 -o loop /usr/local/src/CentOS-7.0-1406-x86_64-DVD.iso /media/cdrom/

mount: /dev/loop0 is write-protected, mounting read-only

# cd /media/cdrom/

[root@mariadb cdrom]# ls

CentOS_BuildTag EULA images LiveOS repodata RPM-GPG-KEY-CentOS-Testing-7

EFI GPL isolinux Packages RPM-GPG-KEY-CentOS-7 TRANS.TBL

[3]设置开机自动挂载系统镜像文件

vim /etc/fstab

/usr/local/src/CentOS-7.0-1406-x86_64-DVD.iso /media/cdrom/ iso9660 defaults,ro,loop 0 0

:x #保存并退出

备注：iso9660 CD-ROM光盘的标准文件系统

mount -l

/usr/local/src/CentOS-7.0-1406-x86_64-DVD.iso on /media/cdrom type iso9660 (ro,relatime) [CentOS 7 x86_64]

[4]配置本地yum源文件；

vim /etc/yum.repos.d/centos7-media.repo

[centos7-media]

name=Red Hat Centos linux 7.0 # 自己定义

baseurl=file:///media/cdrom # 本地镜像文件路径

enabled=1 # 1为启动yum源，0为禁用

gpgcheck=1 # 1为检查GPG-KEY，0为不检查

gpgkey=file:///media/cdrom/RPM-GPG-KEY-CentOS-7 #GPG-KEY文件路径

yum clean all #清除缓存

Loaded plugins: fastestmirror

Cleaning repos: base centos7-media epel extras updates

Cleaning up everything

[5]使用本地yum源安装软件：

# yum --enablerepo=centos7-media search httpd # 查看是否有httpd软件包

...

httpd.x86_64 : Apache HTTP Server

httpd-devel.x86_64 : Development interfaces for the Apache HTTP server

httpd-itk.x86_64 : MPM Itk for Apache HTTP Server

httpd-manual.noarch : Documentation for the Apache HTTP server

httpd-tools.x86_64 : Tools for use with the Apache HTTP Server

...

# yum --enablerepo=centos7-media -y install httpd

Installed:

httpd.x86_64 0:2.4.6-18.el7.centos

# rpm -qa httpd

httpd-2.4.6-18.el7.centos.x86_64

到此本地yum源已配置完毕！
