Question

Can I run LEMP Server and a Node stack on the same droplet?

Asked by Alice

I just setup a LEMP server on Ubuntu 16.04. This is my first time setting up a server from scratch!

I would like to run 3 seperate domains on the same droplet. One is a LEMP site (personal site) and another is a Node.js app that I want to use Node/Express/React/Postgres on. The third one might be a wordpress blog. Anyway…

Two Questions:

#1 I have already created the server blocks for the respective sites. Do I just install all my necessary packages and go from there? Can node and node packages be installed alongside mysql and php?

#2 Do server blocks share all the same access to the packages/servers I install? For example, can all domains use mysql and php or node?

Think of it this way:

Can this road handle 100,000 cars per hour with no bottle necks?

There are a lot of questions to ask:

Was the road built optimally (code for the sites)?
Is the road wide enough (memory allocation per request)?
Are there enough lanes (server size)?
Does it have shoulders to allow people to pull over if they break down (CPU/RAM is able to handle extra load/larger requests)?

So, think of planning a server the way you would a road. Can it handle the traffic? Can it handle 25% more traffic than you expect? Is your code optimized?

As for if the sites can use the same installs of packages: yes.
