The cloud server or VPS needs to be connected using SSH software. there are many types of SSH software, but in this example we choose PuTTY.
Download and open PuTTY software from the official website: PuTTY.org.
Enter the Host Name with the IP address of the cloud server or VPS. Default SSH port is 22 and it does not need to be modified. Click on Open button to connect to server. On a first connection, PuTTY will pop up whether to save server's secret key or not; click “Yes” so that later connections will not pop up this window again.
Now you will automatically be connected to Linux terminal window. Enter the login: “root”, and press Enter key. Then the server will prompt for password, which is completely invisible on the interface to protect password's privacy. After typing the password, press Enter key, to connect to your cloud server or VPS.
