Creating users and managing their permissions on a Virtual Private Server (VPS) involves several steps:
1. Set up the VPS: This includes installing the right operating system (usually Linux or Windows) onto your server.
1. Accessing your VPS: To accomplish this, you can use a Secure Shell (SSH) for Linux-based servers or Remote Desktop Protocol (RDP) for Windows-based servers.
After you have accessed your VPS, here are the steps to create users and manage their permissions on a Linux-based VPS:
1. Create a new user account: You can add a new user by using the command `adduser [username]`. You will be asked to set a password for the new user. It’s a good idea to set a strong password that you will remember.
1. Assign the user to the sudo group: If you want the new user to have administrative privileges, you can add them to the sudo group using `usermod -aG sudo [username]`. The sudo group allows users to execute commands with root permissions.
1. Edit the sudoers file to set permissions: You can set specific permissions for each user by editing the sudoers file. You can edit this file by executing `visudo` command. You can give a user full root access or limit their permissions to certain commands.
1. Confirm that your changes worked: After making changes, you should sign in as the new user and try to execute some commands to make sure your settings have taken effect.
Performing similar tasks on a Windows-based VPS follows a different process:
1. Create a user: Go to computer management -> Local Users and Groups -> Users -> right click and select ‘New User’. Enter the credentials for the new user and click ‘Create’.
1. Adjust permissions: Right click on the new user -> Properties -> Member Of. Here you can assign user to different groups such as ‘Administrators’ for full permissions or ‘Users’ for limited permissions.
Remember, it is important to be careful while managing users and their permissions on VPS, as incorrect configurations can lead to serious security vulnerabilities. Always ensure that you grant only the necessary permissions to each user.
Before doing these actions, especially on a production system, make sure you have a full backup of your server.
Also, it is always recommended to have some basic understanding of Linux or Windows command line before directly jumping into user administration.
