CentOS 7离线环境下搭建共享YUM源的完整步骤

# 如果有本地ISO或已挂载的安装介质，先配置临时本地源
# 挂载CentOS 7安装ISO
mkdir -p /mnt/cdrom
mount -o loop /path/to/CentOS-7-x86_64-DVD.iso /mnt/cdrom

# 配置临时本地repo（仅用于安装nginx等工具）
cat > /etc/yum.repos.d/local.repo << EOF
[local]
name=Local Repository
baseurl=file:///mnt/cdrom
enabled=1
gpgcheck=0
EOF

# 安装nginx
yum install -y nginx

# 启动nginx并设置开机自启
systemctl start nginx
systemctl enable nginx

# 确认防火墙允许80端口
firewall-cmd --permanent --add-service=http
firewall-cmd --reload

# 创建主目录（nginx默认web根目录为/usr/share/nginx/html）
mkdir -p /usr/share/nginx/html/yum-repo/{centos7,updates,epel,local}

# 初始化repodata（以centos7目录为例）
# 如果没有rpm文件，先创建一个空的repodata
cd /usr/share/nginx/html/yum-repo/centos7
createrepo .

yum install -y createrepo

server {
    listen 80;
    server_name _;
    location /yum-repo {
        autoindex on;           # 开启目录列表
        autoindex_exact_size off;
        autoindex_localtime on;
        root /usr/share/nginx/html;
    }
}

nginx -t
systemctl reload nginx

# 将rpm文件放入对应目录
cp /path/to/your-package.rpm /usr/share/nginx/html/yum-repo/local/

# 更新repodata（必须在添加后执行）
cd /usr/share/nginx/html/yum-repo/local
createrepo --update .   # --update 只更新变更，速度快

# 假设所有rpm在/tmp/new-packages目录下
cp /tmp/new-packages/*.rpm /usr/share/nginx/html/yum-repo/local/
cd /usr/share/nginx/html/yum-repo/local
createrepo --update .

# 复制整个Packages目录（以centos7为例）
cp -r /mnt/cdrom/Packages/*.rpm /usr/share/nginx/html/yum-repo/centos7/
cd /usr/share/nginx/html/yum-repo/centos7
createrepo --update .

yum clean all
