Em noob boy kubernete nhờ mọi người giúp ạ

[drgnz]

log có nói rõ rồi đó bạn

@No_name01

–initialize specified but the data directory has files in it. Aborting.
The designated data directory /var/lib/mysql/ is unusable. You can remove all files that the server added to it.

check lại /mnt/data xem sao nha

Trong cái /mnt/data ko có gì hết á anh :’( mà em không đưa nó vô kubernete nữa em đem nó ra docker chạy rồi cho nó lẹ

--ignore-db-dir bị remove ở version 8.0 rồi cậu. Nếu cậu muốn dùng, cậu cần downgrade version xuống 5.7, hoặc dùng lệnh rm để xóa lost+found folder (folder này được tạo by default khi cậu mới format ext4, đó là lý do mysql gào lên như vậy).

Cơ mà, chuyển sang dùng docker cũng là giải pháp

Hope it helps!
