Nignx configuring single IP current limiting

1.http The configuration inside

limit_req_zone $binary_remote_addr zone=rateLimit:10m rate=2r/s;

1.$binary_remote_addr Is the set order ip, Not the total concurrency
2.rateLimit Is a variable with server Just like what is written in it , Some recognize humps , It can be changed to ratelimit etc.
3.2r/s It's for the same ip Limit per second 2 Requests
3.limit_req_zone Must be combined with limit_req To take effect

2.server The configuration inside

 location ~ \.php$ {
        limit_req zone=rateLimit burst=5 nodelay;

2. if rate=2r/s,burst =1, When all requests are not released , front 2 Requests for normal access , The first 3 Requests are queued , The first 4 When a request is made, it will be reported 503
3. During the test, you can refresh quickly

3 . error

2.server The configuration inside

Note first , Just change to the following code
The code inside is from enable-php-73.conf It's stuck inside
