Why does mysql on mac os turn on so strangely when starting the system?

Question

MySQL

Installed mysql on mac os x el capitan, it started doing weird things.
It does not turn on at system startup, but if you delete the mysqld process, it immediately loads itself.
Gifs below. Any thoughts?

Answer 1

See logs.

Answer 2

after updating to El Capitan, it also disappeared, but when I opened the console and tried to connect, I was surprised, it works, the only difference is that I add -h 127.0
