etcd is a distributed key-value store that is used to store data across a cluster of machines. It is often used as part of a larger infrastructure to manage configuration data or as a data store for microservices.
In this tutorial, we will be going through the process of installing etcd on Ubuntu Server Latest step-by-step.
To complete this tutorial, you will need:
The first step in installing etcd is to download the code from the official repository. Use the following command to download etcd:
$ cd /opt/
$ sudo git clone https://github.com/coreos/etcd.git
This will download the etcd source code to the /opt/etcd directory.
Before we can proceed with the installation of etcd, we need to install some prerequisites. Use the following command to install the required packages:
$ sudo apt update
$ sudo apt install -y build-essential autoconf automake libtool
This will install the required packages for building etcd.
Next, we need to build and install etcd. Use the following commands to build and install etcd:
$ cd /opt/etcd/
$ sudo ./build
$ sudo ./configure
$ sudo make
$ sudo make install
These commands will build and install etcd. Once the installation is complete, you can test your installation by running the following command:
$ etcd --version
This should output the version of etcd that you have installed.
Now that we have installed etcd, we need to configure it. Create a new systemd service file for etcd using the following command:
sudo nano /lib/systemd/system/etcd.service
Add the following content to the file:
[Unit]
Description=etcd
After=network.target
[Service]
Type=simple
User=root
EnvironmentFile=-/etc/default/etcd
ExecStart=/usr/local/bin/etcd
[Install]
WantedBy=multi-user.target
Save the file and close it. Then, reload systemd configuration with the following command:
sudo systemctl daemon-reload
Now that we have completed the configuration, we can start the etcd service. Use the following command to start the etcd service:
sudo systemctl start etcd
You can verify that the service is running by running the following command:
sudo systemctl status etcd
This should output the status of the etcd service, which should be active (running).
Congratulations! You have successfully installed etcd on your Ubuntu Server Latest instance. After installation, you can use etcd as a distributed key-value store for your applications.
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!
