In this tutorial, we will be installing etcd, a distributed key-value store from CoreOS, on Arch Linux.
Before proceeding, ensure the following:
The first step is to install the necessary dependencies for etcd. Open the terminal and run the following command:
sudo pacman -S etcd
This command will install etcd and its dependencies.
Next, we need to configure etcd. Arch Linux provides a default configuration file at /etc/etcd/etcd.conf. We can modify this file to suit our needs. For example, to change the default listening port to 2379, open the configuration file using a text editor:
sudo nano /etc/etcd/etcd.conf
In the configuration file, find the following line:
# ETCD_LISTEN_CLIENT_URLS="http://localhost:2379"
Uncomment the line by removing the # at the beginning of the line and modify the port number to 2379:
ETCD_LISTEN_CLIENT_URLS="http://localhost:2379"
Save and close the file.
Once the configuration is done, we can start etcd using the following command:
sudo systemctl start etcd
This command will start the etcd service. To verify if the service is running, we can check its status using the following command:
sudo systemctl status etcd
If the service is running, we should see an output similar to the following:
● etcd.service - etcd
Loaded: loaded (/usr/lib/systemd/system/etcd.service; enabled; vendor preset: disabled)
Active: active (running) since Wed 2021-10-27 12:00:00 UTC; 5s ago
Docs: https://github.com/coreos/etcd
Main PID: 1234 (etcd)
Tasks: 13 (limit: 2062)
Memory: 17.8M
CGroup: /system.slice/etcd.service
└─1234 /usr/bin/etcd
Congratulations! You have successfully installed etcd on Arch Linux. We have also configured etcd and started the etcd service. You can now use etcd for distributed key-value storage. Happy coding!
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!
