Install the NGINX module

  1. Install the Next-Gen WAF NGINX module by running the following command, replacing NN.NN with your NGINX version number:

    $ apk add nginx-module-sigsci-nxo-1.NN.NN

  2. In your NGINX config file (located by default at /etc/nginx/nginx.conf) add the following lines to the global section after the pid /run/nginx.pid; line:

    load_module /etc/nginx/modules/ngx_http_sigsci_module.so;
    load_module /etc/nginx/modules/ndk_http_module.so;

  3. Restart the NGINX service to initialize the new module.

    $ sudo service nginx restart
    $ sudo rc-service nginx restart
