I was checking the memory of each proccess using: but i notice on server with Phpmyadmin installed to have there listed fpmpool 2, fpm pool3 and so on but i do not use multiple pools ..... Pools 2 and 3 etc have 7Mb of ram usage each and the normal ones www around 90Mb On another server that i do not use Phpmyadmin i can see only the one pool www I am wondering why is that?
installing phpmyadmin.sh with separate php-fpm pool will auto enable multiple php-fpm pools as their config files are all located in same directory which nginx uses to read php-fpm pool configs at /usr/local/nginx/conf/phpfpmd/
the additional pools are all ondemand based meaning they don't use any processes really unless actually used by web apps configured to use them if you see fpm pool2 etc listed, then that means you have configured them to be used in your web apps i.e. previously setup etc
