利用 docker 构建动态模块

# 启用 BuildKit
export DOCKER_BUILDKIT=1

# 构建一个包含ip2region的动态模块自定义镜像, 默认版本由参数 `ARG NGINX_VERSION=1.27.0` 控制
docker build -t custom-nginx .

# 构建一个包含ip2region的动态模块自定义镜像, 且指定nginx版本 
docker build -t custom-nginx:1.26.1 --build-arg NGINX_VERSION=1.26.1 .

# 导出动态模块到当前目录, target表示目标阶段, o是output 输出类型和位置
docker build --target export_so -o type=tar,dest=./so.tar .
# 解压即可看到 `ngx_http_ip2region_module.so`, 可将此模块放置到nginx的模块目录,比如 /etc/nginx/modules/
tar xf so.tar 

nginx conf

Syntax: ip2region_db xdb_file_path [cache_policy Optional]; Context: http

cache_policy: file or vectorIndex or content, default: content

Edit nginx.conf add ip2region_db directive

... 

# 如果是动态模块需要使用 load_module 的方式来加载它
# load_module /etc/nginx/modules/ngx_http_ip2region_module.so;

http {

    log_format main escape=json '{'
                                '"remote_addr": "$remote_addr", '
                                '"region": "$ip2region", '
                                '"http_x_forwarded_for": "$http_x_forwarded_for"'
                                '}';

    access_log logs/access.log main;

    # set xdb file path
    ip2region_db ip2region.xdb;
    # ip2region_db ip2region.xdb vectorIndex;
    # ip2region_db ip2region.xdb file;
    # ip2region_db ip2region.xdb content;

    server {
        listen 80;
        server_name localhost;

        location / {
            root html;
            index index.html index.htm;
        }
    }
}

Copy ip2region.xdb to nginx/config (e.g. nginx/conf.d) folder, then restart nginx, the region data stored in ip2region variable

nginx access log sample

{"remote_addr": "127.0.0.1", "region": "0|0|0|内网IP|内网IP", "http_x_forwarded_for": ""}
{"remote_addr": "127.0.0.1", "region": "0|0|0|内网IP|内网IP", "http_x_forwarded_for": ""}
