<div>Hi there,</div>
<div> </div>
<div>> I want to use ngnix to protect my system,to allow max 2000 requests sent to my service(http location).</div>
<div>> The below configs are only for per client ip,not for the total requests control.</div>
<div> </div>
<div>> ##########method 1##########</div>
<div>> </div>
<div>> limit_conn_zone $binary_remote_addr zone=addr:10m;</div>
<div> </div>
<div>http://nginx.org/r/limit_conn_zone</div>
<div> </div>
<div>If "key" is "$binary_remote_addr", it will be the same for the same</div>
<div>client ip, and different for different client ips; the limits apply to</div>
<div>each individual value of client ip (strictly: to each individual value of</div>
<div>"key").</div>
<div> </div>
<div>If "key" is (for example) "fixed", it will be the same for every</div>
<div>connection, and so the limits will apply for all connections.</div>
<div> </div>
<div>Note: that limits concurrent connections, not requests.</div>
<div> </div>
<div>> ##########method 2##########</div>
<div>> </div>
<div>> limit_req_zone $binary_remote_addr zone=one:10m rate=10r/s;</div>
<div> </div>
<div>http://nginx.org/r/limit_req_zone</div>
<div> </div>
<div>Again, set "key" to something that is the same for all requests, and</div>
<div>the limit will apply to all requests.</div>
