Welcome to our blog post on how to manage users and access on a Linux VPS. In this post, we will cover the basics of managing users and setting up access controls on your VPS server. Whether you are new to Linux or looking to enhance your skills, this post is for you!
Creating a New User
One of the first steps in managing users on your Linux VPS is to create a new user. To do this, you can use the ‘adduser’ command in the terminal. Simply type ‘sudo adduser newuser’, replacing ‘newuser’ with the username you want to create. You will be prompted to set a password and provide additional information for the new user.
Setting User Permissions
After creating a new user, you can set permissions to restrict or allow access to certain files or directories. The ‘chmod’ command can be used to change permissions for a specific user, group, or all users. For example, you can use ‘chmod 700 filename’ to give full access to the file for the user and restrict access for others.
Managing User Groups
User groups are a way to organize users with similar permissions or roles. You can create a new group using the ‘addgroup’ command and add users to the group using the ‘usermod’ command. By assigning users to specific groups, you can easily manage permissions for a group of users at once.
Setting Up SSH Keys
Using SSH keys for authentication is a more secure method than using passwords. To set up SSH keys for a user, you can generate a key pair using the ‘ssh-keygen’ command on your local machine and then add the public key to the user’s ‘authorized_keys’ file on the VPS. This will allow the user to log in without entering a password.
