I'm installing a fresh MySQL 5.7 on RedHat 8 using yum

Code:
wget http://dev.mysql.com/get/mysql57-community-release-el7-7.noarch.rpm 
yum localinstall mysql57-community-release-el7-7.noarch.rpm
yum-config-manager --enable mysql57-community
I wrote my easy /etc/mysql/my.cnt

Code:
[mysqld]

datadir=/mysql/data/01
socket=/mysql/admin/01.sock
log-error=/mysql/log/errorlog01.log
pid-file=/mysql/admin/01.pid
U'm now trying to generate my instance


Code:
 -bash-4.2$ mysqld --initialize --explicit_defaults_for_timestamp
