How to install nginx-module-rdns (x86_64)

Description

This module allows to make a reverse DNS (rDNS) lookup for incoming connection and provides simple access control of incoming hostname by allow/deny rules (similar to HttpAccessModule allow/deny directives; regular expressions are supported). Module works with the DNS server defined by the standard resolver directive. This module uses nginx core resolver cache when resolving DNS lookup, for a maximum of 30 seconds or DNS response TTL. To enable this module after installation, add the following to /etc/nginx/nginx.conf and reload NGINX: load_module modules/ngx_http_rdns_module.so; Alternatively, you can enable all installed modules by placing this line at the top of /etc/nginx/nginx.conf: include /usr/share/nginx/modules/*.conf;
