1.新建目錄
# mkdir -p /content/rhel7.1/x86_64/{isos,dvd}/
2.上傳RedHat安裝光盤鏡像，上傳後的路徑為 /content/rhel7.1/x86_64/isos/rhel-server-7.1-x86_64-dvd.iso
3.設置開機自動掛載光盤鏡像到/content/rhel7.1/x86_64/dvd
# echo "/content/rhel7.1/x86_64/isos/rhel-server-7.1-x86_64-dvd.iso /content/rhel7.1/x86_64/dvd iso9660 loop,ro 0 0" >> /etc/fstab
# mount -a
4.搭建http服務器（nginx），用來網絡訪問這個yum源
# rpm -ivh http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm
# yum -y install nginx
5.創建yum源網站(http://content.example.com)配置文件
# vi /etc/nginx/conf.d/content.example.com.conf
server {
listen 80;
server_name content.example.com;
access_log /var/log/nginx/content.example.com.access.log combined;
location / {
root /content;
index index.html index.htm;
autoindex on;
autoindex_exact_size off;
autoindex_localtime on;
}
#error_page 404 /404.html;
# redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /usr/share/nginx/html;
}
}
6.添加DNS記錄到/etc/hosts文件
# echo "192.168.136.254 content.example.com" >> /etc/hosts
7.開通防火牆
# firewall-cmd --permanent --add-service http
# firewall-cmd --reload
8.修改網站目錄SELinux類型
# chcon -t public_content_t -R /content/
9.設置nginx服務開機自啟動，並啟動nginx服務
# systemctl enable nginx
# systemctl start nginx
10.創建repo文件
# vi /etc/yum.repos.d/rhel-dvd.repo
本機：
[rhel-dvd]
name=rhel dvd
baseurl=file:///content/rhel7.1/x86_64/dvd
gpgcheck=0
enable=1
局域網內其他服務器：
[rhel-dvd]
name=remote ipa copy of dvd
baseurl=http://content.example.com/rhel7.1/x86_64/dvd
gpgcheck=0
enabled=1
11.生成repo cache，用來測試新yum源是否生效
# yum makecache
