最近上新项目,搭建nginx的时候为保证安全,决定安装下waf模块,以下是具体步骤,首先下载需要的安装包,进行每个安装:

export LUAJIT_LIB=/usr/local/lib export LUAJIT_INC=/usr/local/include/luajit-2.0 ./configure –prefix=/usr/local/nginx –with-http_stub_status_module –with-http_ssl_module –add-module=/root/ngx_devel_kit-0.2.19 –add-module=/root/lua-nginx- module-0.9.13rc1 –with-http_ssl_module –with-openssl=/root/openssl-1.0.0 –add-module=/root/ngx_cache_purge-1.3 –with-pcre=/root/pcre-8.30 –with-ld-opt=”-Wl,-rpat h,$LUAJIT_LIB” make -j2 make install |
建立目录存放攻击日志:

mkdir -p /data/logs/hack/ chown -R nobody:nobody /data/logs/hack/ chmod -R 755 /data/logs/hack/ |
下载waf,

wget https: //github .com /loveshell/ngx_lua_waf/archive/master .zip –no-check-certificate unzip master.zip cd ngx_lua_waf-master/ mkdir /usr/local/nginx/conf/waf mv * /usr/local/nginx/conf/waf/ cd /usr/local/nginx/conf/ vi nginx.conf |
在http 段加入:
lua_package_path “/usr/local/nginx/conf/waf/?.lua”;
lua_shared_dict limit 10m;
init_by_lua_file /usr/local/nginx/conf/waf/init.lua;
access_by_lua_file /usr/local/nginx/conf/waf/waf.lua;
启动前运行: ln -s /usr/local/lib/libluajit-5.1.so.2 /lib64/libluajit-5.1.so.2 否则会找不到这个模块报错。
过滤规则在wafconf下,可根据需求自行调整,每条规则需换行,或者用|分割
global是全局过滤文件,里面的规则对post和get都过滤
get是只在get请求过滤的规则
post是只在post请求过滤的规则
whitelist是白名单,里面的url匹配到不做过滤
user-agent是对user-agent的过滤规则
