Limit concurrent connections 更多nginx文档 更多linux相关文档 nginx提供了最为基本的方式防御DoS之类的拒绝服务攻击。默认情况下,用户可以拥有的活动连接数没有限制。 nginx支持全局(在nginx http上下文中)切断冗余/不必要的连接,但如果配置全局的限制,可能会对一些server监听产生影响。 当然nginx也支持在每个location下文...

Lastly, you can also limit the number of concurrent connections to your server or the rate of request. 最后,还可以限制到服务器的并发连接数或请求速率。 limit_rate || limit_rate_after 因为我们的公网带宽是十分有限的,当有许多并发用户使用我们的带宽时,这样会形成争抢关系,可能会让某些用户访问大文件...
可以根据压测结果,配置每一台backend server的并发数concurrent。当backend server正在处理的请求超过concurrent值后,upstream就不再会选给该backend server转发新的请求。 官方网站:http://www.open-open.com/lib/view/home/1453172454558
In HTTP/2 and SPDY, each concurrent request is considered a separate connection. There could be severallimit_conndirectives. For example, the following configuration will limit the number of connections to the server per a client IP and, at the same time, the total number of connections to th...
所谓c10k 问题,指的是服务器如何支持 10k 个并发连接,也就是 concurrent 10000 connection(这也是 c10k 这个名字的由来)。 由于硬件成本的大幅度降低和硬件技术的进步,如果一台服务器能够同时服务更多的客户端,那么也就意味着服务每一个客户端的成本大幅度降低。从这个角度来看,c10k 问题显得非常有意义。 C10K问题由...
Nginx自带的limit_conn_module模块(TCP连接频率限制模块)和limit_req_mudule模块(HTTP请求频率限制模块)支持对连接频率以及请求频率、来源进行限制,通常可可以用来防止DDOS攻击。 配置语法: 1.3 配置方式 limit_conn_zone和limit_req_zone会声明一个zone空间来记录连接状态, 才能限制数量。
