i have a lemp stack for wordpress, currently getting an average of 70- 100 visitors per day.
1gb server and mysql keeps crashing. i have netdata on as well, and i keep having to go into the ssh console to restart it as a result.

this is what i see in the error log
Out of memory: Kill process 29383 (mysqld) score 244 or sacrifice child
Killed process 29383 (mysqld) total-vm:1169884kB, anon-rss:288068kB, file-rss:0kB, shmem-rss:0kB

do i need more memory?

worker_processes 1;
pid /run/nginx.pid;
include /etc/nginx/modules-enabled/*.conf;

events {
