Disabling the Default MySQL Module

(EL8 systems only) EL8-based systems such as RHEL8 and Oracle Linux 8 include a MySQL module that is enabled by default. Unless this module is disabled, it masks packages provided by MySQL repositories. To disable the included module and make the MySQL repository packages visible, use the following command (for dnf-enabled systems, replace yum in the command with dnf):

sudo yum module disable mysql

Installing MySQL

sudo yum install mysql-community-server

Starting the MySQL Server

service mysqld start

修改密码

grep ‘temporary password‘ /var/log/mysqld.log

ALTER USER ‘root‘@‘localhost‘ IDENTIFIED BY ‘MyNewPass4@‘;
