MySQL does not work

[2213500360]

Since my system is arm, it seems that sql5.7 does not support it. The following error is prompted：
standard_init_linux.go:219: exec user process caused "exec format error"

So I changed to the sql8.0 version, but it seems that there is a permission problem. I don't know how to solve it：
