knight

knight是基于 openresty 开发的集群API统计、灰度发布、CC防御模块

1、自定义规则进行API统计(运行次数、成功率、运行时间、流量)

2、支持UID以及IP灰度发布

3、支持简单IP频率限制以及IP封禁

4、所有操作均采用api进行操作,无需重启nginx

5、支持集群化

配置

如下是nginx.conf的最小配置 实际knight放路径可以根据实际情况进行调整

lua_package_path "/home/wwwroot/servers/knight/?.lua;;";
lua_code_cache on;
lua_check_client_abort on;

lua_max_pending_timers 1024;
lua_max_running_timers 256;
include /home/wwwroot/servers/knight/config/lua.shared.dict;

init_worker_by_lua_file /home/wwwroot/servers/knight/apps/by_lua/init_worker.lua;
init_by_lua_file /home/wwwroot/servers/knight/apps/by_lua/init.lua;
access_by_lua_file /home/wwwroot/servers/knight/apps/by_lua/access.lua; 
log_by_lua_file /home/wwwroot/servers/knight/apps/by_lua/log.lua;

upstream backend {
    server 0.0.0.1;   # just an invalid address as a place holder
    balancer_by_lua_file /home/wwwroot/servers/knight/apps/by_lua/balancer.lua;
    keepalive 500;  # connection pool
}  

server
{
    server_name knight.domian.cn;
    index index.html index.htm;
    
    location ~ ^/admin/([-_a-zA-Z0-9/]+) {
        set $path $1;
        content_by_lua_file '/home/wwwroot/servers/knight/admin/$path.lua'; 
    }
}

server
{
    server_name domain.host.cn;
    index index.html index.htm;
    #设置默认转发集群weight值越大转发概率越高,在没有通过API设置以及redis挂掉都会采用如下转发规则
    set $default_upstream '[{"ip": "127.0.0.1","port": 8081,"weight":10},{"ip": "127.0.0.1","port": 8082,"weight":5}]';
    location / {
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $http_host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header Connection "";
        proxy_http_version 1.1;
        proxy_pass http://backend;
    }
}
