目的： 需要记录用户真实IP + 访问量
openresty_2">1. 下载openresty：
https://openresty.org/download/openresty-1.25.3.1.tar.gz
2. 编译安装
./configure --help | more 可以查看configure 可选参数
# 1、安装前置依赖
yum install -y readline-devel pcre pcre-devel openssl openssl-devel gcc curl GeoIP-devel perl# 2、编译
##选择模块 ./configure --help
sudo ./configure --with-luajit --with-pcre --with-http_gzip_static_module --with-http_realip_module --with-http_geoip_module --with-http_ssl_module --with-http_stub_status_module --without-lua_resty_redis# 3、安装，默认安装在/usr/local/openresty 目录
sudo gmake
sudo gmake install
luarestyredis_24">3. 安装 lua-resty-redis
说明：安装lua-resty-redis模块主要用于记录关键信息，例如：ip和访问次数。
git clone https://github.com/openresty/lua-resty-redis.gitsudo cp -r lua-resty-redis/lib/resty/* /usr/local/openresty/site/lualib/resty/
lua__ip_redislua__34">4. 创建lua 文件 ip_redis.lua 并引用
lua">local redis = require("resty.redis")
