Tutorial for running latest Fedora version on HostJane cloud servers.
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.
- Developed on a six-monthly release cycle, Fedora is an open-source, widely-used linux operating system that is purposed as a downstream breeding ground and test center of code ideas to fuel Red Hat Linux Enterprise features.
- Choosing Fedora over Ubuntu generally depends on what you need to do with your linux system.
- As Fedora drops support for older versions every 6 months (with twice yearly releases), if your project requires running a long-term linux server, you may be better off with Ubuntu or CentOS.
- Some people who prefer not to learn the Debian Package Management system find Fedora more straightforward to manage.
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 the Dashboard under Services, look for the Fedora server you have provisioned.
We offer 24×7×365 support
If you cannot see your service, open a support case.
B. Click Manage next to the Fedora server item
You will be transferred to the server’s dashboard.
C. Click Statistics in the menu
Below is a sample screenshot of the Server Information.
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
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:
Replace janedoe with the unique name of your new user.
Set a new password for janedoe
You will be automatically asked to set a new password for janedoe, and to reenter the password to confirm.
You should then see confirmation:
passwd: all authentication tokens updated successfully
4. Add super-user privileges
Add janedoe to the wheel group to assign super-user privileges to the user.
gpasswd -a janedoe wheel
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.
6. Verify the configuration
Check that janedoe can successfully log into the server using SSH.
If successful, you will login to your server using your private key and will not be prompted for a password.
7. Disable root user login
Edit the SSH daemon configuration to prevent anyone logging into your server using the root or password authentication.
Use nano, the command-line text editor, to open the SSH daemon file (after logging in with your SSH new super user) by typing:
sudo nano /etc/ssh/sshd_config
Find PermitRootLogin, it will look like this:
Set it to no using your cursor
Check that PasswordAuthentication in the same SSH daemon file is also set to no
Press ctrl + O then Enter to write the changes to SSH daemon
Now close the file with ctrl + x
8. Reload SSH
To save the changes, restart the SSH service:
sudo systemctl reload sshd
9. Enable the firewall
Protect your new Fedora server by enabling the iptables firewall and ensure that the firewall application continues to function after you reboot the server.
Ensure you are logged into your server as your super-user, e.g. janedoe.
We can enable the iptables package by first installing iptables-services:
sudo yum install -y iptables-services
Next, ensure that iptables starts on boot:
sudo systemctl enable iptables
Next, start iptables:
sudo systemctl start iptables
View the default iptables rules on your Fedora server by typing:
sudo iptables -L
To save the rules, which will permit SSH traffic, type:
sudo /usr/libexec/iptables/iptables.init save
Now after you reboot, these ssh firewall rules will persist.
You should see confirmation:
You are now ready to start using your new cloud server!
