Where did the data folder go in mysql 5.7.9?

Question

MySQL

Hello.
Where did the data folder go in MySQL 5.7.9?

Answer 1

I found the info on the subject on the English-language forum. Here is the link and below is the text of the post:

I ended up doing the following...
1) Stop MySQL Service
2) Initialize default mysql database ("data" folder) using command line
mysqld.exe --initialize --user=mysql
3) Run (start) MySQL with passwords disabled
mysqld.exe -u mysql --skip-grant-tables
4) Manually edit `mysql`.`user` table passwords

After executing command number 2, the data folder was indeed created.

Answer 2

dev.mysql.com/doc/relnotes/mysql/5.7/en/news-5-7-9.html
For RPM-based packages, the permissions used to create the data directory (/var/lib/mysql) have been changed from 755 to 751. This tightens the data directory permissions while still permitting world access to the mysql.sock file in that directory. (Bug #21066592)
Judging by this, it hasn't gone anywhere. Sitting in place.
And if you look in my.cnf?

Answer 3

Solved a problem.
I downloaded MySQL 5.7.7 - this is the last version where the data folder was present - and copied it to the latest distribution. Everything works without problems.
