You've signed up for a VPS, and now you have received
root access into the server. Before you do anything else, it's always a good idea to properly set up ssh access, because it's more secure and more convenient.
Note: This guide assumes you are running OSX or Linux locally. The instructions for Windows will be different.
If you haven't already, generate a public-private keypair on your local client.
ssh-keygen -t rsa
Feel free to leave all the options blank. You should get an output that looks like this:
Your identification has been saved in /home/vagrant/.ssh/id_rsa. Your public key has been saved in /home/vagrant/.ssh/id_rsa.pub. The key fingerprint is: 15:0b:f4:36:08:de:df:cb:7d:72:04:0e:7c:3d:97:51 [email protected] The key's randomart image is: +--[ RSA 2048]----+ | ..o . .E| | . o + + .o| | . o * o ooo| | + o + .o| | S . . . .| | . o . | | o o o| | + | | | +-----------------+
Take note of the path to the public key, which in my case is
Log into the VPS using
ssh, replacing "123.456.789.12" with your VPS IP address:
Once you're in, create a new user account on the target server.
sudo adduser <username>
Follow the onscreen instructions to set up the account.
Grant that user sudo access by adding it to the
sudo adduser <username> sudo
While you're here, it's always a good idea to disable root ssh access.
cp /etc/sshd_config /etc/backup_sshd_config sudo nano /etc/sshd_config
Look for the line that begins with
PermitRootLogin, and make sure it says
Restart the sshd service:
service ssh restart
Return to your local terminal by typing
exit. Now you need to copy your public key into the server, like so:
Enter that user's password when requested.
Congratulations, you're done! Check that you can access your server via SSH by entering
