Consul is a powerful service discovery tool. It helps in finding and connecting services across multiple hosts, data centers, and cloud providers. In this tutorial, we'll learn how to install Consul on Debian Latest.
Before we begin, we need:
Before installing Consul on our system, we need to update and upgrade the Debian system to the latest version. For that, use the following command:
sudo apt update && sudo apt upgrade
To download Consul on Debian, use the following command:
curl -OL https://releases.hashicorp.com/consul/1.10.3/consul_1.10.3_linux_amd64.zip
Here, we are downloading Consul version 1.10.3. You can check the latest version on the hashicorp website here.
After downloading, extract the Consul file with the following command:
unzip consul_1.10.3_linux_amd64.zip
The Consul executable will be extracted to the current directory.
To move the Consul executable to the system directory, use the following command:
sudo mv consul /usr/local/bin/
To verify that Consul is installed correctly, use the following command:
consul version
This will display the current version of Consul on your system.
To start Consul in server mode, use the following command on the terminal:
consul agent -server -bootstrap-expect=1 -data-dir=/tmp/consul
Here, we are starting Consul in server mode with -server. We are setting the -bootstrap-expect flag to 1, which means we expect one server in the cluster. We are also specifying a -data-dir flag, where Consul will store its data.
In this tutorial, we learned how to install Consul on Debian Latest. Consul is a powerful tool that aids in service discovery, and we can now use it to solve many distributed system problems.
If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
Alternatively, for the best virtual desktop, try Shells!
