Tutorial for running latest CentOS version on HostJane cloud servers.
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 the Dashboard under Services, look for the CentOS 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 CentOS 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
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.
Set a new password for janedoe
passwd janedoe
At the prompt, reenter the new password and confirm by pressing Enter
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.
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. 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:
PermitRootLogin yes
Set it to no using your cursor
PermitRootLogin no
Check that PasswordAuthentication in the same SSH daemon file is also set to no
PasswordAuthentication no
Press ctrl + O then Enter to write the changes to SSH daemon
Now close the file with ctrl + x
7. Reload SSH
To save the changes, restart the SSH service:
sudo systemctl reload sshd
8. Set the server time zone
Edit the /usr/share/zoneinfo directory
Pull up a list of your server's timezones by running:
ls -R /usr/share/zoneinfo
You’ll see an output, such as:
Use sudo command to change your timezone:
sudo ln -sf /usr/share/zoneinfo/Time/Zone /etc/localtime
Replace /Time/Zone with your actual location’s timezone, e.g. /US/Arizona
sudo ln -sf /usr/share/zoneinfo/US/Arizona /etc/localtime
Now run the date command to test that your janeCloud’s timezone is updated.
date
If successful, the output will give you Arizona (GMT -7) time:
Day Month Day 00:00:00 MST Year
You are now ready to start using your new cloud server!
