一、yum源共享
服务端：
- 安装http协议
- 关闭防火墙
- 挂载yum源镜像到网络共享目录
yum install httpd -y
systemctl stop firewalld
systemctl disable firewalld
systemctl start httpd
systemctl enable httpd
mkdir /var/www/html/source7.0
可以通过在浏览器中输入：http://服务端ip/rhel7
可以看到镜像中的内容，代表挂载没有问题
更改yum源配置文件
[kiosk@foundation79 Desktop]$ vim /etc/yum.repos.d/yum.repo | [rhel7.2] name=rhel7.2 baseurl=file:///var/www/html/soource7.0 gpgcheck=0 |
将镜像挂载到网络共享目录下
mount mount /iso/rhel-server-7.0-x86_64-dvd.iso /var/www/html/rhel7.0
df ##参看设备挂载情况
客户机：
更改yum源配置：
vim /etc/yum.repos.d/rhel_dvd.repo
| [rhel_dvd] gpgcheck = 0 enabled = 1 baseurl = http://172.25.254.79/source7.0 name = Remote classroom copy of dvd |

效果检验
客户机：
配置之前：
[root@localhost ~]# yum search ImageM
Loaded plugins: langpacks
http://content.example.com/rhel7/repodata/repomd.xml: [Errno 14] curl#7 - "Failed connect to content.example.com:80; No route to host"
Trying other mirror.
配置之后：
[kiosk@foundation79 Desktop]$ yum search ImageM
Loaded plugins: langpacks, product-id, search-disabled-repos, subscription-
: manager
rhel7.2 | 4.1 kB 00:00
(1/2): rhel7.2/group_gz | 134 kB 00:00

Name and summary matches only, use "search all" for everything.二、第三方yum源配置
1、创建一个文件夹，并把需要的RPM安装包存放到这
[root@foundation79 mnt]# mkdir /mnt/yum_local
[root@foundation79 mnt]# mv vincent.rpm yum_local/
2、使用createrepo在RPM包的路径下创建YUM索引数据库
[root@foundation79 mnt]# createrepo yum_local/
Spawning worker 0 with 1 pkgs
Spawning worker 1 with 0 pkgs
Spawning worker 2 with 0 pkgs
Spawning worker 3 with 0 pkgs
Workers Finished
Saving Primary metadata
Saving file lists metadata
Saving other metadata
Generating sqlite DBs
Sqlite DBs complete
创建完成后，会多一个repodata文件夹：
[root@foundation79 mnt]# ls yum_local/repodata/*
yum_local/repodata/0ba95458f34b58ca25c8419ba5a3a4af91ae99ad12f18d3d937d3d421cfd362f-primary.sqlite.bz2
yum_local/repodata/11148022609abc00018b877b565a4bc4b1cb11b9a510e1d2cd3a83acd6b0e1c5-filelists.sqlite.bz2
yum_local/repodata/2f8f58f9c973195abd254944d0c0d0a40f67ebd2eb2dbd27fc943b311608bd37-primary.xml.gz

yum_local/repodata/516ef7bc957978862f7e1eedbc7d47b949e6cdf8ab24f2dd8a265765b552a6ea-filelists.xml.gz
yum_local/repodata/ebe0b2b5db08f8272bb018d59bc69c62a89f6c320c6a7f78e90f7c39237648d7-other.sqlite.bz2
yum_local/repodata/repomd.xml
3、更改本地yum.repo文件，指向本地YUM源
[root@foundation79 mnt]# cat > /etc/yum.repos.d/yum.repo << end
> [local_yum]
> name=my_yum
> baseurl=file:///mnt/yum_local
> gpgcheck=0
> end
4、清除YUM以前的缓存信息
[root@foundation79 mnt]# yum clean all
Loaded plugins: langpacks, product-id, search-disabled-repos, subscription-manager
This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.
Cleaning repos: local_yum
Cleaning up everything检验结果：
[root@foundation79 mnt]# yum repolist
Loaded plugins: langpacks, product-id, search-disabled-repos, subscription-manager
This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.
