3 下载ngx_lua并解压
wget https://github.com/chaoslawful/lua-nginx-module/archive/v0.9.6.tar.gz tar xf v0.9.6.tar.gz
4 重新编译安装nginx
./configure --user=www --group=www --prefix=/usr/local/nginx --with-http_stub_status_module --without-http-cache --with-http_ssl_module --with-pcre=/home/soft/pcre-8.31 --add-module=/home/lua-nginx-module-0.9.6 --add-module=/home/ngx_devel_kit-0.2.19 make make install
5 下载ngx_lua_waf并解压
wget https://github.com/loveshell/ngx_lua_waf/archive/master.zip unzip master.zip mv master /usr/local/nginx/ngx_lua_waf/
6 修改 nginx的配置文件 根据实际情况更改路径
lua_need_request_body on; lua_package_path \"/usr/local/nginx/conf/ngx_lua_waf/?.lua\"; lua_shared_dict limit 10m; init_by_lua_file /usr/local/nginx/conf/ngx_lua_waf/init.lua; access_by_lua_file /usr/local/nginx/conf/ngx_lua_waf/waf.lua;
