How to realize Speed limit and current limit in Nginx

How to achieve speed limit and current limit in Nginx? In view of this problem, today the editor summarizes this article about Nginx, hoping to help more friends who want to solve this problem to find a more simple and feasible way.

First create a file denyIP to write the filtered IP to it, and then make a path in the configuration file

Include / usr/local/nginx/conf/denyIP

Zone:=one:10m: set a cache space named one with a size of 100m

M = minutes, s = seconds, 2000 requests per minute, or 200 requests per second

Limit_req_zone $binary_remote_addr zone=one:100m rate=2000r/m

Define a limit_req_zone named allips to store session, with a size of 50 MB of memory

Limit_req_zone $binary_remote_addr zone=allips:50m rate=200r/s

Burst=5: because the traffic is not uniform all the time like a leaky bucket, in order to avoid the occurrence of large-scale traffic at a certain time, the burst parameter is added. Here, set a buffer with a size of 5. When a large number of requests (outbreaks) come, the access exceeds the above limit and can be placed in the buffer first.

Limit_req zone=one burst=5 nodelay
