# 编辑nginx.conf文件，在http块中添加以下配置:
vim /etc/nginx/nginx.conf
http {
    ...
    lua_package_path "/etc/nginx/ngx_lua_waf/?.lua";
    lua_shared_dict limit 10m;
    init_by_lua_file /etc/nginx/ngx_lua_waf/init.lua;
    access_by_lua_file /etc/nginx/ngx_lua_waf/waf.lua;
    ...
}

# 配置waf规则文件
vim /etc/nginx/ngx_lua_waf/config.lua
RulePath = "/etc/nginx/ngx_lua_waf/wafconf/"  --规则存放目录
attacklog = "on"  --是否开启攻击信息记录，需要配置logdir
logdir = "/home/wwwlogs/"  --log存储目录，需要nginx用户的可写权限。日志文件名称格式如下:虚拟主机名_sec.log
UrlDeny = "on"  --是否拦截url访问
Redirect = "on"  --是否拦截后重定向
CookieMatch = "on"  --是否拦截cookie攻击
postMatch = "on"  --是否拦截post攻击
whiteModule = "on"  --是否开启URL白名单
black_fileExt = {"php","jsp"}  --填写不允许上传文件后缀类型
ipWhitelist = {"127.0.0.1"}  --ip白名单，多个ip用逗号分隔
ipBlocklist = {"1.0.0.1"}  --ip黑名单，多个ip用逗号分隔
CCDeny = "on"  --是否开启拦截cc攻击(需要nginx.conf的http段增加lua_shared_dict limit 10m;)
CCrate = "100/60"  --设置cc攻击频率，单位为秒. 默认1分钟同一个IP只能请求同一个地址100次
html = [[Please go away~~]]  --警告内容,可在中括号内自定义</code>
