The load balancer can be any host that you have available that's capable of running NGINX. +> +>One caveat: do not use one of your Rancher nodes as the load balancer. + +### A. Install NGINX + +Start by installing NGINX on your load balancer host. NGINX has packages available for all known operating systems. + +For help installing NGINX, refer to their [install documentation](https://www.nginx.com/resources/wiki/start/topics/tutorials/install/). + +### B. Create NGINX Configuration + +After installing NGINX, you need to update the NGINX config file, `nginx.conf`, with the IP addresses for your nodes. + +1. Copy and paste the code sample below into your favorite text editor. Save it as `nginx.conf`. + +2.

Save `nginx.conf` to your load balancer at the following path: `/etc/nginx/nginx.conf`. + +4. Load the updates to your NGINX configuration by running the following command: + + ``` + # nginx -s reload + ``` + +### Option - Run NGINX as Docker container + +Instead of installing NGINX as a package on the operating system, you can rather run it as a Docker container. Save the edited **Example NGINX config** as `/etc/nginx.conf` and run the following command to launch the NGINX container: + +``` +docker run -d --restart=unless-stopped \ + -p 80:80 -p 443:443 \ + -v /etc/nginx.conf:/etc/nginx/nginx.conf \ + nginx:1.14 +``` + +## 3. Configure DNS + +Choose a fully qualified domain name (FQDN) that you want to use to access Rancher (e.g., `rancher.yourdomain.com`).

+ +1. Log into your DNS server a create a `DNS A` record that points to the IP address of your [load balancer](#2-configure-load-balancer). + +2. Validate that the `DNS A` is working correctly. Run the following command from any terminal, replacing `HOSTNAME.DOMAIN.COM` with your chosen FQDN: + + `nslookup HOSTNAME.DOMAIN.COM` + + **Step Result:** Terminal displays output similar to the following: + + ``` + $ nslookup rancher.yourdomain.com + Server: YOUR_HOSTNAME_IP_ADDRESS + Address: YOUR_HOSTNAME_IP_ADDRESS#53 + + Non-authoritative answer: + Name: rancher.yourdomain.com + Address: HOSTNAME.DOMAIN.COM + ``` + +
+ +## 4. Download RKE + +RKE is a fast, versatile Kubernetes installer that you can use to install Kubernetes on your Linux hosts. We will be using RKE to setup our cluster and run Rancher. + +1. From your workstation, open a web browser and navigate to our [RKE Releases](https://github.com/rancher/rke/releases/latest) page. Download the latest RKE installer applicable to your Operating System: + + - **MacOS**: `rke_darwin-amd64` + - **Linux**: `rke_linux-amd64` + - **Windows**: `rke_windows-amd64.exe` + +2. Make the RKE binary that you just downloaded executable. Open Terminal, change directory to the location of the RKE binary, and then run one of the commands below. + + >**Using Windows?** + >The file is already an executable. Skip to [Download RKE Config File Template](#5-download-rke-config-file-template). + + ``` + # MacOS + $ chmod +x rke_darwin-amd64 + # Linux + $ chmod +x rke_linux-amd64 + ``` + +3. Confirm that RKE is now executable by running the following command: + + ``` + # MacOS + $ ./rke_darwin-amd64 --version + # Linux + $ ./rke_linux-amd64 --version + ``` + + **Step Result:** You receive output similar to what follows: + ``` + rke version v + ``` + +## 5.

Continue to [What's Next?](#what-s-next) + +By default, Rancher automatically generates self-signed certificates for itself after installation.
