Ok noob here. I'm willing to learn the necesarry steps myself I just need to be pointed into the right directon.
I set up a server on digitalocean.com
512 MB RAM, 1 CPU, 20GB SSD
OS: CentOS 7
I installed a LAMP stack with apache, mariadb and php and hosted a simple wordpress site, right now there isn't traffic nor are any plugins installed etc, just a fresh installation.
When I check memory usage with
free -h my server uses about 380MB out of 490MB, the memory isn't used to cache but actually is in use, I only have 30MB available, it also swaps out additional 200MB to my 1GB swap file.
When I run htop and check which processes consume most memory there are like eight
/usr/sbin/httpd
processes which consume between 8 and 8.5% each and about 19
/usr/libexec/mysqld
processes consuming 5% each.
Since the CPU load is equal to zero on those processes I guess they are just waiting, not actually doing anything?
When I check mariadb's error logfile there isn't really anything, a couple of warnings about a Ip adress couldn't be resolved that's it.
Is this normal usage and my server simply is on it's limit due to it's specs or is there something wrong? Do I have to limit mysqlds memory usage?
