Comments on Rate Limiting with Nginx
Rate Limiting With nginx. This article explains how to use the nginx HttpLimitReqModule to limit the number of requests for a given session. This is useful, for example, if your site is hammered by a bot doing multiple requests per second and thus increasing your server load. With the HttpLimitReqModule you can define a rate limit, and if a visitor exceeds this rate, he will get a 503 error.

yeahh nice stuff thank you man !!
Hi Falko.
This is a perfect step to protect an entire server, but how to deal with multiple vhost and ISPConfig?
I mean, I can define the zone in nginx.conf for the entire server, but where must I define the location containers?
Must I do it per vhost? What's about ispconfig.vhost and apps.vhost? They are restored by default after few minutes...
Thanks in avance for your time!
thannkkkk youuuuuuuuuuu this is worked for me
i added here:
location / {
limit_req zone=one burst=5 nodelay;try_files $uri $uri/ /index.php?$args;
location ~* ^.+\.(jpeg|jpg|png|gif|bmp|ico|svg|css|js)$ {
expires 10y;
}
and when i was cry i found you bro and i added here:
location ~ [^/]\.php(/|$) {
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
if (!-f $document_root$fastcgi_script_name) {
return 404;
}
fastcgi_pass 127.0.0.1:9001;
fastcgi_index index.php;
include /etc/nginx/fastcgi_params;
limit_req zone=one burst=5;
}
and this is working now and my images works :D
This doesn't work anymore.
# nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: [emerg] zero size shared memory zone "one"
nginx: configuration file /etc/nginx/nginx.conf test failed
It does work...
you are probably missing directive
limit_req_zone $binary_remote_addr zone=one:10m rate=1r/s;
So in your /etc/nginx/nginx.conf under http {... put the declaration of the zone
Then in your virtual host file e.g. /etc/nginx/sites-enabled/my.site.cnf under location call the limit_req_zone= one burst=5;
then try nginx -t
