[Help] Knowledge for maintaining a server

Hi guys, a very straightforward question here....
Please tell me what skills do I need to have to run my own mu online server, fix bugs and add new mods to the game (new map, or a quest npc, or a script... things like that)

I tried asking in many places but nobody gave me an answer :glare::(:
Thanks in advance!

Hello.

You must know the programming languages that the server uses IN DEPTH. I've seen a lot of newbies doing stuff while they don't even know the programming language they're working with. When you know the programming language, I'm assuming you have some common sense of security. You'd need to know what things like SQL injection is if you're working with a MySQL service. There's not really 1 'correct' answer to your question.

Thank you for taking your time to answer my question. SQL is one thing I need to learn but what programming languages might a server use?

Any programming language that can handle a server. Things like Node.js or Java.
