配置本地yum源

我这里直接安装的RHEL7的操作系统，使用的是最小化安装，默认很多RPM都没有安装上，友情链接：U盘启动安装Linux系统

我这里演示两种配置YUM本地源，一种是通过U盘，另一种是通过远程Windows共享目录的方式，友情链接：Linux yum源

1. U盘作为本地YUM源

• 插入并且mount U盘
• 制作YUM源文件

Steps：

[root@localhost ~]# fdisk -l #查看U盘信息

Units = sectors of 1 * 512 = 512 bytes

I/O size (minimum/optimal): 512 bytes / 512 bytes

Disk identifier: 0x442146ee

Disk /dev/mapper/rhel-root: 53.7 GB, 53687091200 bytes, 104857600 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes

Disk /dev/sdb: 8022 MB, 8022982656 bytes, 15669888 sectors

Sector size (logical/physical): 512 bytes / 512 bytes

Disk identifier: 0xcad4ebea

   Device Boot      Start         End      Blocks   Id  System
/dev/sdb4   *         256    15669887     7834816    b  W95 FAT32
[root@localhost ~]# mount /dev/sdb4 /mnt/usb/ #mountU盘到指定目录
[root@localhost ~]# cat /etc/yum.repos.d/rhel-local.repo #新建yum源文件
[rhel_7]
name=local_iso
baseurl=file:///mnt/usb
enabled=1
gpgcheck=1
gpgkey=file:///mnt/usb/RPM-GPG-KEY-redhat-release

2. 用远程Windows共享目录的方式

• 因为我这里使用的是最小化安装，所以首先要用第一种方式把cifs-utils这个rpm包安装上
• 在windows上新建一个directory，共享，并且确保rhel7能够访问
• 把yum源copy到上面新建的共享directory里面
• mount共享directory
• 制作YUM源文件

Steps：

[root@localhost ~]# mount -t cifs //IP/os_share_rhel7 /mnt/rhel7_iso/ -o username=account #mount windows上面的共享directory
Password for username@//IP/os_share_rhel7:  *********
[root@localhost ~]# cat /etc/yum.repos.d/rhel-local.repo #新建yum源文件
[rhel_7]
name=local_iso
baseurl=file:///mnt/rhel7_iso
enabled=1
gpgcheck=1
gpgkey=file:///mnt/rhel7_iso/RPM-GPG-KEY-redhat-release
[root@localhost ~]# mount -t cifs IP:share_folder /mnt/linux_share -o user=username #另外一种方式，不同于上面使用的是//，而是使用的冒号(:)
