To load a module at runtime, include the new load_module directive in the main context, specifying the path to the shared object file for the module, enclosed in quotation marks. When you reload the configuration or restart NGINX, the module is loaded in. You can specify a path relative to the source directory, as in these examples, or a full path.

load_module "modules/ngx_http_geoip_module.so";
load_module "modules/ngx_stream_module.so";
