Prerequisites

• A FreeBSD latest server with root access
• A user with sudo privileges
• Basic knowledge of the FreeBSD command-line interface

Step 1: Install Dependencies

Before installing Consul on FreeBSD Latest, you must install the required dependencies using the following command:

sudo pkg install -y wget unzip

Step 2: Download Consul Binary

Next, you will need to download the Consul binary from the official Consul downloads page. You can do this by running the following command:

sudo wget -O /usr/local/bin/consul https://releases.hashicorp.com/consul/1.10.3/consul_1.10.3_freebsd_amd64.zip

Note that you should replace the version number in the URL with the latest version at the time of installation.

Step 3: Verify Consul Binary

sudo sha256 /usr/local/bin/consul

If the output matches the SHA256 checksum of the specific version you downloaded, you can proceed to the next step.

Step 4: Configure Consul Server

{
  "data_dir": "/var/lib/consul",
  "server": true,
  "bootstrap_expect": 1,
  "client_addr": "0.0.0.0",
  "advertise_addr": "<SERVER_IP_ADDRESS>",
  "bootstrap_expect": 1,
