Installing multiple WordPress sites with separate domain names on a cloud server is simpler than you may think.

Add the following records with your domain and your server’s IP address that you were emailed:

With the server’s root password that you were emailed, login via SSH:


ssh root@example.com
The authenticity of host 'example.com (00.000.000.000)' can't be established.
RSA key fingerprint is **:**:**:**:**:**:**:**:**:**:**:**:**:**:**:**.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added 'example.com,00.000.000.000' (RSA) to the list of known hosts.
root@example.com's password: ********


Change root password:


passwd
