ipquery

基于ngx_lua的纯真库ip信息查询服务

原理

使用lua的c api编写ip查询逻辑作为lua的扩展库，直接在nginx中执行lua代码，无需上游服务

使用

• 安装nginx和ngx_lua模块（或者直接安装openresty）
• 编译ip查询模块的lua扩展：cd src; gcc -Wall -O2 -shared -fPIC -llua ip_lua_bingding.c ip.c -o ipquery.so
• 复制ipquery.so到lualib目录
• 按照conf/nginx.conf修改你的nginx配置文件
• 启动nginx
• have funs

性能

机器：4核CPU，4G内存的虚拟机，4个nginx worker进程
