@Sylvain2008 some parts of PHP need to be run as root to work properly without these permission PHP would not work, e.g. a connection between PHP and Nginx (to explain it in the easiest way).

I have 3 PHP processes :-).

And thank you, it is my pleasure to help.

PS: You can use Linux Dash, it is really good : https://github.com/afaqurk/linux-dash

Welcome to DigitalOcean,

here are some basics of Linux (Ubuntu) : https://help.ubuntu.com/community/UsingTheTerminal

Everything with PHP sounds normal, some stuff needs to be run as root.

MySQL has a high RAM usage and 512MB are enough for the beginning.

Hi eldin,

Thank you for taking the time to answer and providing me with this link. The shortcuts section will be particularly useful, I really appreciate.

I’ll dig in deeper about this, I get why there’s a php5 process running as www-data because I asked for it and configured it to be like this.

I’m more annoyed about the other process that comes out of the blue and am looking at understanding why it’s there (triggered by a cron, spawned by nginx, whatever).

Knowledge about this will come in its time, I guess :) Thanks again!
