# Set Up NGINX If you don't want HTTPS (for communications between the external world and your node), then you can skip all the NGINX steps on this page. Note: This simple deployment template uses NGINX for more than just HTTPS. For example, it also does basic rate limiting. ## Install NGINX SSH into your machine and install NGINX: ``` sudo apt update sudo apt install nginx ``` ## Configure & Reload NGINX Get an SSL certificate for your node's subdomain (such as `bnode.example.com`). * Copy the SSL private key into `/etc/nginx/ssl/cert.key` * Create a "PEM file" (text file) by concatenating your SSL certificate with all intermediate certificates (_in that order, with the intermediate certs last_). * Copy that PEM file into `/etc/nginx/ssl/cert.pem` * In the [bigchaindb/bigchaindb repository on GitHub](https://github.com/bigchaindb/bigchaindb), find the file `nginx/nginx.conf` and copy its contents to `/etc/nginx/nginx.conf` on your machine (i.e. replace the existing file there). * Edit that file (`/etc/nginx/nginx.conf`): replace the two instances of the string `example.testnet2.com` with your chosen subdomain (such as `bnode.example.com`). * Reload NGINX by doing: ``` sudo service nginx reload ```
