limit_rate是Nginx配置中的一个指令,用于限制Nginx服务器与客户端之间的数据传输速率。通过该指令,可以设定每个连接的最大传输速率,从而避免单个客户端过度占用服务器带宽资源。 2. 说明limit_rate配置的作用 limit_rate的主要作用是控制客户端的下载速度,防止因某个客户端的下载行为导致服务器带宽被过度占用,进而影响其...
Rate limiting is a powerful feature of NGINX that can mitigate DDoS attacks, which would otherwise overload your servers and hinder application performance. In this webinar, we cover basic concepts as well as advanced configuration. We finish with a live demo that shows NGINX rate limiting in ac...
Currently, when the shared memory storage reaches 20 megabytes and the rate limit is set to 10 requests per second, the new request is returned or rejected, and you also know that this is not the best way to handle the client (unless they are bots). In such cases, you use theburstpar...

本文主要是对nginx官方limit_rate相关指令的用法解释和一些个人理解,limit_rate主要用于限制用户和服务器之间传输的字节数,最常用的场景可能就是下载/上传限速,在如今用户网速普遍大幅提升的情况下,对于一些文件传输、视频流媒体传输等服务还是有着一定的应用场景的。
limit_rate_after允许在传输部分数据后进行限速，如分段下载或视频加载初期不进行限速。proxy_limit_rate与limit_rate类似，用于限制nginx与上游服务器间的连接速率，需开启proxy_buffering指令生效。limit_rate的一大优势在于其支持变量的使用，结合map指令，能够实现动态限速。例如，通过匹配时间或使用变量，实现...
