ngx_lua_waf完整安装说明

1、安装nginx_lua_module模块
mkdir /data/soft
上传nginx1.4.4，LuaJIT-2.0.3，ngx_devel_kit-0.2.19、lua-nginx-module-0.9.11

unzip LuaJIT-2.0.3.zip
cd LuaJIT-2.0.3
make&&make install
出现如下内容，表示安装成功
==== Successfully installed LuaJIT 2.0.3 to /usr/local ====

tar -zxvf ngx_devel_kit-0.2.19.tar.gz
tar -zxvf lua-nginx-module-0.9.11.tar.gz


以下为以/usr/local/nginx/conf/nginx.conf中加入作为nginx安装路径为例说明
tar -zxvf nginx-1.4.4
cd nginx-1.4.4 
export LUAJIT_LIB=/usr/local/lib
export LUAJIT_INC=/usr/local/include/luajit-2.0
export LD_LIBRARY_PATH=/usr/local/lib/:$LD_LIBRARY_PATH  
./configure --prefix=/usr/local/nginx --add-module=/data/soft/ngx_devel_kit-0.2.19 --add-module=/data/soft/lua-nginx-module-0.9.11
make -j2
make install

在/usr/local/nginx/conf/nginx.conf中加入以下内容并保存
server{
......
    location /hello { 
          default_type ‘text/plain‘; 
          content_by_lua ‘ngx.say("hello, lua")‘; 
    }
}

/usr/local/nginx/sbin/nginx –t 检查nginx配置，应无报错
/usr/local/nginx/sbin/nginx 

访问localhost/hello，会出现“hello,lua，说明安装成功!

2、安装并配置ngx_lua_waf
cd /usr/local/nginx/conf
rz 上传ngx_lua_waf-master.zip
tar -zxvf ngx_lua_waf-master.zip
rm ngx_lua_waf-master.zip
mv ngx_lua_waf-master waf
vi conf/nginx.conf，在http段添加以下内容并保存退出
    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;

以nginx进程用户为www为例说明
mkdir -R /usr/local/nginx/logs/hack
chown -R www:www /usr/local/nginx/logs/hack/
chmod -R 755 /usr/local/nginx/logs/hack/

如果nginx安装路径和攻击日志存储路径与上述示例不一致，需要
vi waf /config.lua修改RulePath和logdir

重启nginx
/usr/local/nginx/sbin/nginx –s reload

访问：域名/etc/passwd，页面提示：Please go away~~ ，同时/usr/local/nginx/logs/hack/目录下生成类似server_name-2014-08-26_sec.log的文件，说明安装配置成功

如果需要修改页面提示内容，可以修改config.lua中的html字段内容为：403 Fprbidden

rm -rf /data/softl
