Recommended amount of WordPress installations on a droplet?

Posted July 5, 2015 5.1k views


I use the smallest droplet of Ubuntu LAMP 14.04 that uses 512MB of ram. Is there an minimum recommendation of amount of RAM for running a single WordPress installation? I would like to run at least two WordPress installations on different domains on the same droplet. These two webpages is not heavily trafficated.

Would it work fine using the smallest droplet, or should I upgrade? What is your recommendation?

Kind regards

I run up to 7 Wordpress sites on a single 512mb droplet. The sites are all low to medium traffic.

If I know a website is going to be very busy, I give it it’s own droplet.
If a site will be using woocommerce or such, I give it its own droplet

setting up a swap would help things quite a bit.

There is a tutorial somewhere on DO, and also a guy made a script that does it for you ( I just use this script when I set up a new droplet)

I’m using the same setup, 15 sites all with their own WP installs on a single $5 droplet, all low traffic… I do have swap operational…
Here are the instructions for swap…

sudo fallocate -l 2G /swapfile (creates 2gb swapfile)

sudo chmod 600 /swapfile (restricts permissions)

sudo mkswap /swapfile (creates swapfile directory)

sudo swapon /swapfile (turns swapfile on)

sudo sh -c 'echo "/swapfile none swap sw 0 0" >> /etc/fstab' (turns swapfile on every boot)

sudo shutdown -r now (reboots server)

Good luck :)
