What scripts will help to properly configure the VPS server under load?

Question

Server optimization

Hello.
I independently administer a small number of sites on VPS. There were problems with the load on the mysql database and found the script mysqltuner. Followed the instructions and everything is working fine. In this regard, I had a question:
What other scripts are there that will help optimize the server settings for the current load?
Any analogues of mysqltunner for php, nginx and in general to keep the server in a fast state.

Answer 1

More scripts, download different cool ones! And run them without looking.
Only then do not complain that you were broken, and everything is gone.
It is necessary to think with your own head, and not thoughtlessly run all sorts of dregs.

Answer 2

Optimization consists in selecting a load that is similar to a typical load on a resource and selecting script execution parameters and environment parameters
To solve a problem, in general, it will be necessary to determine a huge number of system templates.
Such tasks are not solved automatically
We look at our stack
We look at the manuals for each element of the stack
We make a script for a typical load and based on common sense and {io,h}top we tune the system
