# Creating a new user on your Linux server and configuring it for administrative tasks
|
|
|
|
## 1. Create a New User
|
|
|
|
- Log in to Your Server as the root user or a user with sudo privileges.
|
|
- Add a New User:
|
|
`sudo adduser newusername`
|
|
Replace `newusername` with the desired username.
|
|
- Follow the prompts to set the user's password and provide additional information.
|
|
|
|
## 2. Grant Sudo Privileges (Optional)
|
|
|
|
If you need the new user to have administrative privileges, add the user to the sudo group:
|
|
|
|
- Add User to the Sudo Group:
|
|
`sudo usermod -aG sudo newusername`
|
|
This command adds the user to the sudo group, which grants administrative permissions.
|
|
|
|
## 3. Configure SSH Access
|
|
|
|
- Switch to the New User:
|
|
`su - newusername`
|
|
- Create SSH Directory and Authorized Keys:
|
|
`mkdir -p ~/.ssh
|
|
chmod 700 ~/.ssh
|
|
touch ~/.ssh/authorized_keys
|
|
chmod 600 ~/.ssh/authorized_keys`
|
|
- Add Your Public Key to authorized_keys:
|
|
- Open authorized_keys in an editor:
|
|
`vim ~/.ssh/authorized_keys`
|
|
- Paste your SSH public key into the file
|
|
|
|
## 4. Configure SSH Access for New User
|
|
|
|
Ensure the new user can log in via SSH:
|
|
|
|
- Edit the SSH Configuration File (/etc/ssh/sshd_config):
|
|
`sudo nano /etc/ssh/sshd_config`
|
|
- Verify or Add the Following Settings:
|
|
`PermitRootLogin no
|
|
AllowUsers newusername`
|
|
`PermitRootLogin no` disables root login via SSH.
|
|
`AllowUsers newusername` allows the new user to log in.
|
|
- Restart SSH Service:
|
|
`sudo systemctl restart ssh`
|
|
|
|
## 5. Test SSH Access
|
|
|
|
- Log Out from the Root User or current session.
|
|
- Log In as the New User:
|
|
`ssh newusername@your_server_ip`
|
|
- Verify that you can access the server with the new user.
