nginx current limiting algorithm

nginx current limiting mainly includes the limit_conn module and the limit_req module

limit_conn limits the number of connections, and limit_req limits the request rate

limit_conn limits the current

http {

limit_conn_zone $binary_remote_addr z/p>

limit_conn_log_level error;

limit_conn_status 503;

server {

...

location /{

limit_conn addr 2

}

limit_req limit_req_zone $binary_remote_addr z rate= 5r/s;

limit_req_log_level error;

limit_req_status 503;

server {

...

location /{

limit_req z burst=3;

}

}

The above has introduced the nginx current limiting algorithm, including aspects of it. I hope it will be helpful to friends who are interested in PHP tutorials.
