Hello,

On new server I removed mariadb and and I want to install MySQL 8.0 but but I see this error:

Code:

auto.cnf binlog.index

drwx--x--x 2 mysql mysql 4096 Feb 7 13:44 mysql

I tried deleting the directory /var/lib/mysql and starting the installation again - it doesn't help.

# uname -r
5.14.0-547.el9.x86_64

Please help.
 
I left it as it was installed, in /usr/local/mysql-8.0.41.

Symlinks (created by not me):
/usr/local/mysql -> /usr/local/mysql-8.0.41
/usr/local/mysql-8.0.41/data -> /var/lib/mysql

:LOL::LOL::LOL:
