why is my centos, nginx, php,mysql server using so much memory
- by kb2tfa
i'm not sure where the problem lies. I have:
centos 6
mysql
php
php-fpm
wordpress (1 site).
this is a dedicated server i'm learning on.
as soon as i ran the web url the memory slammed to 125% of a 512k server, i had to upgrade to 1gig, so i'm not sure where the problem lies. I thought by switching to nginx from apache i would have more memory free, but i'm still stuck with the problem.
before launching the site with nginx and mysqld running the site was about 5% memory.
I reanamed my "my-small.cnf" to my.cnf and put in my /etc folder where the original was, but that seems not to have done it.
after looking at my TOP results, i'm starting to think it may be php-fpm eating my memory, but not sure.
is php-fpm the preferend way or is there something better to use. I read about possible memory leaks in php-fpm.
here is what i have:
php-fpm.conf
