Question

MySQL on a separate droplet

  • Posted on March 6, 2014

Hello,

I currently have one droplet with ubuntu/lamp. In order to scale horizontally I would like to put MySQL on a dedicated droplet.

But I could not figure out where to start and how to secure the communication between the two droplets (ssh tunneling, vpn, …) while allowing communication between php on one side and MySQL on the other.

If someone have any guidance on this it would be great :) Thanks!

Finally, install a firewall on your droplet so that only your app server can connect to your MySQL server: <a href=“https://www.digitalocean.com/community/articles/how-to-setup-a-firewall-with-ufw-on-an-ubuntu-and-debian-cloud-server”>https://www.digitalocean.com/community/articles/how-to-setup-a-firewall-with-ufw-on-an-ubuntu-and-debian-cloud-server</a>.
