参考代码

首先 需要的依赖：

libmaxminddb

https://github.com/maxmind/libmaxminddb

maxmind-geoip

https://github.com/Dreamacro/maxmind-geoip

libmaxminddb 需要gcc编译，可用 Dockerfile 里面编译生成so文件，然后复制到 openresty/openresty:centos-rpm 镜像中，然后把 Country.mmdb（Ip数据库） 也复制到镜像中

Dockerfile 如下：

############## 构建 libmaxminddb #####################
FROM gcc:9 AS libmaxminddb-build
ADD lib/libmaxminddb-1.8.0.tar.gz /
WORKDIR /libmaxminddb-1.8.0
RUN ./configure && make && make install && ldconfig -v && ls -f  /usr/local/lib/libmaxminddb*############## 构建 openresty #####################
FROM openresty/openresty:centos-rpm
ENV TZ Asia/Shanghai
COPY --from=libmaxminddb-build   /usr/local/lib/libmaxminddb.so.0.0.7 /lib64
COPY  geoip/20231212/Country.mmdb /etc/nginx/mmdb/Country.mmdbRUN  ln -snf /usr/share/zoneinfo/"$TZ" /etc/localtime && echo "$TZ" > /etc/timezone \&& opm get anjia0532/lua-resty-maxminddb \&& ln -s /lib64/libmaxminddb.so.0.0.7 /lib64/libmaxminddb.so \&& ldconfig -v

然后配置lua脚本，OpenResty（也称为 ngx_openresty）是一个基于 Nginx 与 Lua 的高性能 Web 平台，

lua脚本如下：

local function get_client_ip()local headers = ngx.req.get_headers()local clientIP = headers["x-forwarded-for"]if clientIP == nil or string.len(clientIP) == 0 or clientIP == "unknown" thenclientIP = headers["Proxy-Client-IP"]endif clientIP == nil or string.len(clientIP) == 0 or clientIP == "unknown" thenclientIP = headers["WL-Proxy-Client-IP"]endif clientIP == nil or string.len(clientIP) == 0 or clientIP == "unknown" thenclientIP = ngx.var.remote_addrend-- 对于通过多个代理的情况，第一个IP为客户端真实IP,多个IP按照','分割if clientIP ~= nil and string.len(clientIP) > 15 thenlocal pos = string.find(clientIP, ",", 1)clientIP = string.sub(clientIP, 1, pos - 1)endreturn clientIP;
endlocal function check_cn(ip)local geo = require 'resty.maxminddb'if not geo.initted() thengeo.init("/etc/nginx/mmdb/Country.mmdb")endlocal res, err = geo.lookup(ip)if not res thenngx.log(ngx.ERR, ' failed to lookup by ip , reason :', err)elsefor k, v in pairs(res) doif (k == "country") thenfor key, item in pairs(v) doif (key == "iso_code") thenif item == "CN" thenngx.log(ngx.INFO, ' this counrty: ', item)return 1;elsengx.log(ngx.ERR, ' this counrty: ', item)return 0;endendendendendend
end-- 获取nginx 本地缓存
local cache_ngx = ngx.shared.dis_cache;
-- 获取 请求IP
local clientIP = get_client_ip();--根据IP 获取本地黑名单缓存数据
local banIpCache = cache_ngx:get('ban_ip_' .. clientIP);
if banIpCache == 1 thenngx.log(ngx.ERR, "cache_black_ip:", clientIP)ngx.exit(403)
else-- 判断是否是国外IP, 直接设为黑名单,并且返回403local flag = check_cn(clientIP);if flag == 0 then-- 本地缓存黑名单 时间1小时ngx.log(ngx.ERR, "set_local_black_ip:", clientIP)cache_ngx:set('ban_ip_' .. clientIP, 1, 60 * 60);ngx.exit(403)end
end

nginx.conf 配置文件 也要加入 lua脚本校验，以及 增加128M的本地缓存，方便过滤

nginx.conf如下：

pcre_jit on;#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;error_log  logs/error.log  warn;#pid        logs/nginx.pid;worker_processes auto;events {worker_connections  20480;
