Nginx Proxy Manager是一个预构建的Docker镜像，可以轻松地将您在家中或其他地方运行的网站转发到外部，并提供免费的SSL证书，无需了解太多关于Nginx或Letsencrypt的知识。在互联网日益普及的今天，使用本项目可以帮助您更加方便地管理和部署网站，同时也提高了您的网站的安全性。无论您是初学者还是有经验的开发人员，本项目都将为您提供便捷的使用体验。

搭建环境

• 安装好 docker

部署Nginx Proxy Manager

version: '3'
services:
  app:
    image: 'jc21/nginx-proxy-manager:latest'
    restart: unless-stopped
    ports:
      - '80:80'
      - '81:81'
      - '443:443'
    volumes:
      - ./data:/data
      - ./letsencrypt:/etc/letsencrypt
    
networks:
  default:
    external: true
    name: ngpm

sudo docker network create ngpm
mkdir -p ~/base/NGPM && cd ~/base/NGPM && nano docker-compose.yml
sudo docker-compose up -d
# 登录到 http://ip:81
# Email: admin@example.com
# Password: changeme
# 反代 Nginx Proxy Manager

申请泛域名证书

1. 获取 cloudflare API 令牌
2. API 令牌模板选择【编辑区域 DNS】
3. 记录下 dns_cloudflare_api_token
4. 进入NGPM管理页面，添加证书
   
5. 添加证书时选择 DNS验证，填入记录下的dns_cloudflare_api_token
   

开启 Gzip 压缩

cd ~/base/NGPM && mkdir -p data/nginx/custom
cat << EOF > data/nginx/custom/server_proxy.conf
gzip on;
gzip_min_length 256;
gzip_comp_level 9;
gzip_types *;
gzip_vary on;
gzip_buffers 32 4k;
EOF

添加基本身份验证

1. 添加 Access List
   
2. 配置账号密码
   
3. 配置基本身份验证
   

示例：反代 WordPress

version: '3.1'
services:
  wordpress:
    image: wordpress
    restart: always
    volumes:
      - ./www:/var/www/html
 
networks:
  default:
    external: true
    name: ngpm

mkdir -p ~/app/WordPress && cd ~/app/WordPress && nano docker-compose.yml
sudo docker-compose up -d
# 反代写法如下 serviceName:port

• 进入 wp-content 目录
• 下载 db.php (来自项目 wp-sqlite-db)
• 重命名 wp-config-sample.php 为 wp-config.php
• nano ~/app/WordPress/www/wp-config.php
• 访问 salt 修改对应的salt
• 按添加下面的代码，修改数据库位置
• 访问网站完成安装

define('DB_DIR', '/absolute/custom/path/to/directory/for/sqlite/database/file/');
define('DB_FILE', 'custom_filename_for_sqlite_database');
if(isset($_SERVER['HTTP_X_REAL_IP'])) {
    $list = explode(',',$_SERVER['HTTP_X_REAL_IP']);
    $_SERVER['REMOTE_ADDR'] = $list[0];
    $_SERVER['HTTPS']='on';   
    $_SERVER["SERVER_PORT"] = 443;
    define('WP_HOME', 'https://'.$_SERVER['HTTP_HOST']);
    define('WP_SITEURL', 'https://'.$_SERVER['HTTP_HOST']);
    define('WP_CONTENT_URL', 'https://'.$_SERVER['HTTP_HOST'].'/wp-content');
    define('FORCE_SSL_LOGIN', true);
    define('FORCE_SSL_ADMIN', true);
}

附加 代理文本文件

location /hello.txt {
  alias /data/hello.txt;
}
location = /baidu_verify_codeva.html {
    return 200 abcde;
}

附加 代理 web-ui

location / {
    gzip on;
    gzip_min_length 256;
    gzip_comp_level 6;
    gzip_types text/plain text/xml application/javascript application/x-javascript text/css application/xml text/javascript application/x-httpd-php image/jpeg image/gif image/png application/vnd.ms-fontobject font/ttf font/opentype font/x-woff image/svg+xml;
    gzip_vary on;
    gzip_buffers 32 4k;
    root /data/web-ui;
    try_files $uri $uri.html $uri/index.html =404;
    error_page 404 /404.html;
}

附加 随机图片

location = /randomImg {
	content_by_lua_block {
		local randomNumber = string.format("%02d", math.random(1, 10))
		local randomUrl = "https://img.limour.top/randImg/" .. randomNumber .. ".webp"
		ngx.status = 302
		ngx.header["Location"] = randomUrl
		ngx.exit(ngx.HTTP_MOVED_TEMPORARILY)
	}
}

location = /randomImg {
	content_by_lua_block {
		local redirectList = {
			"http://a.com",
			"http://b.com",
			"http://c.com"
		}
		local randomIndex = math.random(1, #redirectList)
		local randomUrl = redirectList[randomIndex]
		ngx.status = 302
		ngx.header["Location"] = randomUrl
		ngx.exit(ngx.HTTP_MOVED_TEMPORARILY)
	}
}

附加 端口转发

sudo apt install rinetd
sudo nano /etc/rinetd.conf
# 格式 [source_address] [source_port] [destination_address] [destination_port]
sudo rinetd
sudo systemctl status rinetd.service
