My question is this,
My friend before install rathena basically on windows,
But I prefer using rhel and centOs
now I use CentOs 8 Stream,
In doing so, I use, nodejs and using NGINX to proxy my websites,
i'm also using PostgresSQL
look at your documents,
I saw that I'll be force to use apache for this
MySQL/MariaDB
I use pm2 to start processes in my webapps,
in your case, in my anyway shape or form
do I integrate Rathena to my system?
without using the LAMP/Apache HTTP set it up
For MariaDB, do I need to use Lamp/Xamp to actually use it,
or just run the server and let the client do the rest ?
