最终结果，不搞了，一直报错

nginx: [emerg] module "/usr/local/nginx/modules/ngx_http_geoip2_module.so" is not binary compatible

要不就是编译以后用静态的可执行文件替换/usr/bin/nginx，也是会有其他报错
等后面有需要再弄吧，这里只是做个进度记录

发现一个可以参考的
https://www.cnblogs.com/tinywan/p/6965467.html

sudo -i
apt update -y && apt upgrade
cd /home
apt -y install gcc g++ nginx git autoconf automake make libpcre3-dev zlib1g zlib1g-dev libpcre3-dev libssl-dev

这些包现在不安装也行，后面报错的时候会让你安装的。

wget https://github.com/maxmind/libmaxminddb/releases/download/1.7.1/libmaxminddb-1.7.1.tar.gz
tar -zxvf libmaxminddb-1.7.1.tar.gz && cd libmaxminddb-1.7.1

编译安装libmaxminddb:

./configure
make
make check
make install
ldconfig

cd /home
git clone https://github.com/leev/ngx_http_geoip2_module
wget http://nginx.org/download/nginx-1.18.0.tar.gz
tar -zxvf nginx-1.18.0.tar.gz && cd nginx-1.18.0/
systemctl stop nginx

编译动态加载模块

./configure --add-dynamic-module=/home/ngx_http_geoip2_module
make && make install
cp /home/nginx-1.18.0/objs/ngx_http_geoip2_module.so '/usr/local/nginx/modules/ngx_http_geoip2_module.so'

配置文件开头加入load_module /usr/local/nginx/modules/ngx_http_geoip2_module.so;动态加载
vim /etc/nginx/nginx.conf

user www-data;
worker_processes auto;
pid /run/nginx.pid;
include /etc/nginx/modules-enabled/*.conf;
load_module /usr/local/nginx/modules/ngx_http_geoip2_module.so;

events {
        worker_connections 768;
        # multi_accept on;
}
