Initializing mysql directory error

Question

I checked this page: http://dev.mysql.com/doc/refman/5.7/en/mysql-install-db.html

mysql_install_db is removed, however, when I use mysqld --initialize. It promotes these errors and warning.

[Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details).

[ERROR] --initialize specified but the data directory has files in it. Aborting.
[ERROR] Aborting

The first one can be ignored according to this:How to enable explicit_defaults_for_timestamp?

I don't know how to solve the second problem.

Answer 1

Pls, read error carefully:

[ERROR] --initialize specified but the data directory has files in it. Aborting.

Your directory is not empty. You have to remove all the contents of it or choose another one.
