How to Install Cockpit on Ubuntu 18.04

Cockpit: Web page tool for easy management of GNU/Linux servers

Cockpit is a powerful server management tool that allows you to easily manage GNU/Linux servers through a web browser. It simplifies tasks such as startup containers, storage management, network configuration, and log checking.

Main advantages of Cockpit:

• Web interface management: Easy to manage the server through a browser, without mastering complex command-line operations.
• Seamless switching between terminal and web tools: Services started on Cockpit can be stopped in terminal and vice versa.
• Extensive Linux distribution compatibility: Supports numerous Linux distributions, including Ubuntu, and is well compatible with Alibaba Cloud Elastic Computing Services (ECS) servers.
• Multi-server management: Multi-server management can be monitored and managed at the same time.

Install Cockpit on Ubuntu 18.04:

Ubuntu 18.04 already includes Cockpit, and the installation process is very simple:

1. Update package list: sudo apt update
2. Installing Cockpit: sudo apt -y install cockpit
3. Start and enable Cockpit:

   sudo systemctl start cockpit.socket
   sudo systemctl enable cockpit.socket

4. Access through browser: https://ip-address:9090 (Replace ip-address with your server IP address). Cockpit uses a self-signed SSL certificate, which you may need to add exceptions to your browser to access.

Cockpit cannot completely replace the command line, but it provides a friendly graphical interface to make server management more convenient and efficient. It is especially suitable for users who want to simplify server management processes but do not need to have a deep understanding of the command line.
