在部署一个openlist的drive.yukifuhane.cn.eu.org后想要在同一台机子部署一个VPN域名为los.yukifuhane.dpdns.org但因为80和443端口已被占用，需要直连或者反代签证，我这边是设置请求8080端口，通过反代文件验证达到签证证书。网上没有这块太多的教程，也踩了不少坑

安装acme和nginx

$ apt install nginx
# 设置开机自启动
$ systemctl enbale nginx
# 下载acme与创建符号链接
$ curl https://get.acme.sh | sh
$ ln -s  /root/.acme.sh/acme.sh /usr/local/bin/acme.sh

先让我们进行域名签证

$ acme.sh --set-default-ca --server letsencrypt
# Openlist
# 创建证书存放位置
$ mkdir /etc/drive
$ acme.sh  --issue -d drive.yukifuhane.cn.eu.org -k ec-256 --webroot  /var/www/html
$ acme.sh --install-cert -d drive.yukifuhane.cn.eu.org --ecc --key-file /etc/drive/server.key  --fullchain-file /etc/drive/server.crt --reloadcmd "systemctl force-reload nginx"
$ docker run -itd --name openlist -p 5244:5244 -p 5245:5245 -v /mnt/openlist/data:/opt/openlist/data -v /etc/drive:/mnt/drive openlist:latest

nginx相关配置

niginx安装会默认有个WebSite，在 /var/www/html我们则需要复制一份

# 创建VPN站点
# mkdir -p /var/www/vpn
cp -r /var/www/html /var/www/vpn

# ========= 直连静态文件模式（8080）=========
server {
    listen 8080;
    server_name los.yukifuhane.dpdns.org;

    # 指向和 acme.sh --webroot 参数一致的目录
    root /var/www/vpn;

    # 只处理 ACME challenge 请求
    location /.well-known/acme-challenge/ {
        # 直接尝试读取本地文件，找不到就 404
        try_files $uri =404;
    }
}

# ========= 反代模式（供 80 端口正常站点使用）=========
server {
    listen 80;
    server_name los.yukifuhane.dpdns.org;

    # 如果是 ACME 验证路径，直接用本地文件，不重定向到 HTTPS
    location /.well-known/acme-challenge/ {
        root /var/www/vpn;
        try_files $uri =404;
    }

    # 其他普通请求才反代到 HTTPS 或后端

}

# ========= HTTPS 模式（正常业务服务）=========
server {
    listen 443 ssl http2;
    server_name los.yukifuhane.dpdns.org;

    # 你的证书路径（等申请下来以后替换）
    ssl_certificate /etc/nginx/ssl/los.yukifuhane.dpdns.org.fullchain.pem;
    ssl_certificate_key /etc/nginx/ssl/los.yukifuhane.dpdns.org.key;

    root /var/www/vpn;
    index index.html;

    location / {
        try_files $uri $uri/ =404;
    }
}

让我们接着配置对VPN的域名进行签证
