Optimization of Nginx for 128 MB RAM VPS

Hello,

I have a 128 MB RAM VPS with 1 vcore of 2,2 GHz x86_64 CPU. The CPU is
much
faster than the Rapsberry one so that is not a problem but the RAM
usage, I
think, is.

Could You help me optimize my Nginx installation?

Thats my configuration:

nginx.conf:

The worker_process value is set to the number of vcores which is 1, so
it’s
OK, I guess.

But what with the worker_connections? I have read that this is the
number of
simultaneous connections a single process can handle. How high should
this
value be? I am expecting lets say 20 connections per hour. I will host
there
only my personal home page and my school notebook (based on Wordpress).
Will
increasing this value result in high usage of RAM by idling nginx
waiting
for new connections?

PHP-FPM pools configs:

How should I configure the pm values for each of this websites/vhosts?
The
one called “zeszyt” is my notebook based on Wordpress, The “pma” one is
the
phpMyAdmin and the rest are just normal website builded with my own
simple
PHP scripts and HTML files.

Should I set there something more to e.g. to make the file upload
possible
like with the phpMyAdmin or it will just work out of the box like with
Apache and PHP module?

Thanks in advance


Best regards,
Aleksander Kurczyk

Personally I don’t think that you need any optimizations for such load.

Is this really needed? Nginx doesn’t use much RAM usually. How much RAM
does
nginx use currently and what is the target usage you would like to
achieve?

The most important thing is probably to disable all plugins, third party
and build-in.

As echoed by others, I’d hardly be worrying about 20 requests / hour,
but
just FYI, that’s a maximum number, so if you’re not using it, it won’t
really consume more RAM. nginx handles many connections very well, so
it
won’t really matter if you set it a fair bit higher.

Generally PHP/MySQL would be your optimisation targets as they’ll
consume
way more RAM than nginx, but again, for your load, I wouldn’t be
worried.

If you’re uploading large dumps, you may wish to increase the size of
client_max_body_size:

And PHP’s post_max_size:
