配置本地ISO源

一、简述

系统：centos7

环境：VMware虚拟机

二、配置步骤

配置过程(挂在虚拟机默认虚拟光驱的iso镜像)

  2 [root@localhost ~]# ls /mnt/
  3 hgfs
  4 [root@localhost ~]# mkdir /mnt/cdrom
  5 [root@localhost ~]# ls /dev/cdrom
  6 /dev/cdrom
  7 [root@localhost ~]# ll /dev/cdrom
  8 lrwxrwxrwx. 1 root root 3 Jan  5 19:07 /dev/cdrom -> sr0
  9 [root@localhost ~]# mount -t auto /dev/cdrom /mnt/cdrom/
 10 mount: /dev/sr0 is write-protected, mounting read-only
 11 [root@localhost ~]# ls /mnt/cdrom/
 12 CentOS_BuildTag  EULA  images    LiveOS    repodata              RPM-GPG-KEY-CentOS-Testing-7
 13 EFI              GPL   isolinux  Packages  RPM-GPG-KEY-CentOS-7  TRANS.TBL
 14 [root@localhost ~]# cd /etc/yum.repos.d/
 15 [root@localhost yum.repos.d]# ls
 16 CentOS-Base.repo  CentOS-Debuginfo.repo  CentOS-Media.repo    CentOS-Vault.repo
 17 CentOS-CR.repo    CentOS-fasttrack.repo  CentOS-Sources.repo  CentOS-x86_64-kernel.repo
 18 [root@localhost yum.repos.d]# mkdir otherRepo
 19 [root@localhost yum.repos.d]# mv CentOS-* otherRepo/

如果虚拟机存储了ISO镜像，则可以

  1 通过以下命令将ISO镜像挂载到本地yum目录/yum/local下。
  2 
  3 mount -o loop /yum/iso/CentOS-7-x86_64-DVD-1804.iso /yum/local/


创建本地yum源文件

  1 [root@localhost yum.repos.d]# vi Local.repo
  2 [centos7-local]
  3 name=Centos 7.0
  4 baseurl=file:///mnt/cdrom
  5 enabled=1
  6 gpgcheck=0
  7 gpgkey=


  1 [root@localhost yum.repos.d]# yum clean all
  2 Loaded plugins: fastestmirror
  3 Cleaning repos: centos7-local
  4 Cleaning up list of fastest mirrors
  5 Other repos take up 201 M of disk space (use --verbose for details)
  6 [root@localhost yum.repos.d]# yum makecache
  7 Loaded plugins: fastestmirror
  8 Determining fastest mirrors
  9 centos7-local                                                             | 3.6 kB  00:00:00
 10 (1/4): centos7-local/group_gz                                             | 166 kB  00:00:00
 11 (2/4): centos7-local/primary_db                                           | 5.9 MB  00:00:00
 12 (3/4): centos7-local/filelists_db                                         | 6.9 MB  00:00:00
 13 (4/4): centos7-local/other_db                                             | 2.5 MB  00:00:00
 14 Metadata Cache Created
 15 [root@localhost yum.repos.d]# yum install net-tools


三、更改默认源为国内阿里源

1、安装wget

  1 yum install -y wget

2、下载CentOS 7的repo文件
  1 wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
  2 
  3 或者
  4 curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
  5


3、更新镜像源

  1 清除缓存：
  2 yum clean all
  3 生成缓存：
  4 yum makecache

更改配置文件（很重要）
1、备份CentOS 7系统自带yum源配置文件/etc/yum.repos.d/CentOS-Base.repo命令：

  1 mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup

2、找到yum源的配置路径

  1 cd /etc/yum.repos.d
