Installer and script uploaded on Centos7 VPS A with cPanel/WHM, while mySQL database and user are created on Centos7 VPS B with Centos Web Pannel. Need to establish remote access to mySQL on host B for host A.
Host A is witelisted on host B, mysql user on host B is registered with host A IP. Remote mysql access is allowed on host A to host B, [login to view URL] of the script on host A is correspondingly changed with host B mysql user and db credentials. Still no connection or proper authentication.
I have worked as server admin for big names like [login to view URL] and servercentre.net. Over 8yrs of working with cpanel, directadmin and plesk servers. Can help you with this. Let me know.
Did you had checked the firewall rules on server B. Are you able to telnet MySQL port of server B to from Server A About myself https://www.freelancer.com/u/redssr.html
