LuaJIT安裝
yum -y install gcc gcc-c++ autoconf automake make unzip
yum -y install zlib zlib-devel openssl openssl-devel pcre pcre-devel
cd /usr/local/src/
wget http://luajit.org/download/LuaJIT-2.0.5.tar.gz
tar xf LuaJIT-2.0.5.tar.gz
cd LuaJIT-2.0.5
make && make install
安裝Lua Ngx模塊
wget https://github.com/simplresty/ngx_devel_kit/archive/v0.3.0.tar.gz
tar xf v0.10.13.tar.gz
echo "export LUAJIT_LIB=/usr/local/lib" >> /etc/profile
echo "export LUAJIT_INC=/usr/local/include/luajit-2.0" >> /etc/profile
source /etc/profile
Nginx添加Lua模塊
cd /usr/local/src/
wget http://nginx.org/download/nginx-1.14.0.tar.gz
tar xf nginx-1.14.0.tar.gz
cd nginx-1.14.0
useradd -s /sbin/nologin -M www
./configure --user=www --group=www \
--prefix=/usr/local/nginx-1.14.0 \
--with-http_stub_status_module \
--with-http_ssl_module \
--with-http_gzip_static_module \
--pid-path=/usr/local/nginx-1.14.0/nginx.pid \
--with-http_realip_module \
--add-module=/usr/local/src/ngx_devel_kit-0.3.0 \
--add-module=/usr/local/src/lua-nginx-module-0.10.13 \
--with-ld-opt="-Wl,-rpath,$LUAJIT_LIB"
make -j2
make install
ln -s /usr/local/nginx-1.14.0 /usr/local/nginx
準備Lua waf防護腳本
https://github.com/loveshell/ngx_lua_waf
mkdir -p /usr/local/nginx/logs/hack/
chown -R www.www /usr/local/nginx/logs/hack/
chmod -R 755 /usr/local/nginx/logs/hack/
至此nginx支持WAF防護功能已經(jīng)搭建完成方援！
使用說明：
nginx配置文件路徑為:/usr/local/nginx/conf/
把ngx_lua_waf下載到conf目錄下,解壓命名為waf
wget https://github.com/loveshell/ngx_lua_waf/archive/master.zip
unzip master.zip -d /usr/local/nginx/conf/
mv /usr/local/nginx/conf/ngx_lua_waf-master /usr/local/nginx/conf/waf
在nginx.conf的http段添加下面這段：
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;
配置config.lua里的waf規(guī)則目錄(一般在waf/conf/目錄下)：
RulePath = "/usr/local/nginx/conf/waf/wafconf/" #絕對路徑如有變動欢揖，需對應(yīng)修改
然后重啟nginx即可。
配置文件詳細說明：
RulePath = "/usr/local/nginx/conf/waf/wafconf/"
--規(guī)則存放目錄
attacklog = "off"
--是否開啟攻擊信息記錄玉凯，需要配置logdir
logdir = "/usr/local/nginx/logs/hack/"
--log存儲目錄，該目錄需要用戶自己新建漫仆，切需要nginx用戶的可寫權(quán)限
UrlDeny="on"
--是否攔截url訪問
Redirect="on"
--是否攔截后重定向
CookieMatch = "on"
--是否攔截cookie攻擊
postMatch = "on"
--是否攔截post攻擊
whiteModule = "on"
--是否開啟URL白名單
black_fileExt={"php","jsp"}
--填寫不允許上傳文件后綴類型
ipWhitelist={"127.0.0.1"}
--ip白名單嫉鲸，多個ip用逗號分隔
ipBlocklist={"1.0.0.1"}
--ip黑名單，多個ip用逗號分隔
CCDeny="on"
--是否開啟攔截cc攻擊(需要nginx.conf的http段增加lua_shared_dict limit 10m;)
CCrate = "100/60"
--設(shè)置cc攻擊頻率歹啼，單位為秒.
--默認1分鐘同一個IP只能請求同一個地址100次
html=[[Please go away~~]]
--警告內(nèi)容,可在中括號內(nèi)自定義
備注:不要亂動雙引號玄渗，區(qū)分大小寫
啟動nginx：
/usr/local/nginx/sbin/nginx
檢查規(guī)則是否生效：
部署完畢可以嘗試如下命令：
curl http://your_ip/test.php?id=../etc/passwd
結(jié)果如下則說明規(guī)則生效（頁面修改地址：/usr/local/nginx/conf/waf/config.lua）：
圖片.png
注意:默認座菠，本機在白名單不過濾，可自行調(diào)整config.lua配置
一些說明：
過濾規(guī)則在wafconf下藤树，可根據(jù)需求自行調(diào)整浴滴，每條規(guī)則需換行,或者用|分割
args里面的規(guī)則get參數(shù)進行過濾的 url是只在get請求url過濾的規(guī)則 post是只在post請求過濾的規(guī)則 whitelist是白名單，里面的url匹配到不做過濾 user-agent是對user-agent的過濾規(guī)則
默認開啟了get和post過濾岁钓，需要開啟cookie過濾的升略，編輯waf.lua取消部分--注釋即可
日志文件名稱格式如下:虛擬主機名_sec.log
