sudo apt-get install libnginx-mod-stream
```
Rate limiting crawlers is done by adding the following to `/etc/nginx/conf.d/limit.conf`:
```
# http://nginx.org/en/docs/http/ngx_http_limit_req_module.html
# https://blog.nginx.org/blog/rate-limiting-nginx
map $http_user_agent $isbot_ua {
default 0;
~*(GoogleBot|GoogleOther|bingbot|YandexBot) 1;
}
map $isbot_ua $limit_bot {
0 "";
1 $binary_remote_addr;
}
limit_req_zone $limit_bot zone=bots:10m rate=1r/m;
limit_req_status 429;
```
and the following in the location to be rate limited:
```
location / {
limit_req zone=bots burst=2 nodelay;
...
```
