Production-ready requirements

We recommend several steps before you install any software layer onto the new environment.

This is an important security step if you are intending on using your server for production projects.

1. Get server IP and root password

After successful payment is approved, your server will be set up within 2 minutes.

A. Login to the Hosting Portal

Bookmark login: https://console.hostjane.com/client/login

In your Dashboard under Services, find your Ubuntu server.

We offer 24×7×365 support

If you cannot see your Ubuntu service, open a support case.

B. Click the Manage option

This is the button in the last column under Services.

Here is the next screen that will display:

C. Click Statistics in the side menu

The Main IP is your virtual machine’s IP address.

The Default Password is the root password.

For security, HostJane does not send this to you by email.

You must login to your hosting account to review these credentials.

2. Login with SSH

Login to your server with PuTTY on Windows or an OpenSSH client in linux and MacOS devices:

ssh -l root [Your_Server's_IP]

Replace Your_Server’s_IP with the server IP address given in Statistics.

3. Create a new user

For security reasons it’s best not to use the root user for everyday administrative tasks.

The solution is to create a new user.

Enter the following:

adduser janedoe

Replace janedoe with the unique name of your new user.

You will be automatically asked to set a new password for janedoe, and to reenter the password to confirm.

Press Enter to proceed with default information, otherwise enter values for your:

1. Full name
2. Room number
3. Work phone
4. Home phone
5. Other

4. Install sudo on Ubuntu

Add janedoe to the sudo group to assign super-user privileges to the user.

usermod -aG sudo janedoe

Your new user can now have root privileges using sudo commands.

5. Set up public SSH keys

We recommend you set up an SSH key pair to secure your server.

SSH key setup is easy and free, but if you’re not comfortable doing this we recommend hiring a system administrator on HostJane Marketplace.

After you’ve set up your SSH keys, open another terminal on your local machine.

Add your SSH key to janedoe‘s home directory via the new terminal.

ssh-copy-id janedoe@Your_Server's_IP

With the SSH key now installed, log back into your cloud server using your new janedoe user.

ssh -1 janedoe Your_Server's_IP

Login should be successful.

Close all other open terminals.

6. Switch to new user to enter home directory

Substitute janedoe for the user you created in step 3.

su - janedoe

Create a new directory .ssh and restrict permissions:

mkdir ~/.ssh

Ensure there are no spaces between / and .ssh

chmod 700 ~/.ssh

Use nano, the command-line text editor, to edit the authorized_keys file in .ssh directory by typing:

chmod 600 ~/.ssh/authorized_keys

Type exit to switch back to the root user.

7. Verify the configuration

Check that janedoe can successfully log into the server using SSH.

Enter:

SSH janedoe@[Your_Server's_IP]

If successful, you will login to your server using your private key and will not be prompted for a password.

8. Disable root login

Only disable root logins if you have set up SSH keys on the server, otherwise you’ll be locked out.

Edit the SSH daemon file to prevent unauthorized users logging into your server using password authentication.

Login by SSH to your server with your new super-user, for example, janedoe

Use nano, the command-line text editor, to open the SSH daemon file:

sudo nano /etc/ssh/sshd_config

Find PermitRootLogin, it will look like this:

PermitRootLogin yes

Set it to no using your cursor

PermitRootLogin no

Press ctrl + O then Enter to write the changes to SSH daemon

Now close the file with ctrl + x

9. Reload SSH

To save the changes, restart the SSH service:

sudo systemctl restart sshd

You are now ready to start using your new cloud server!
