After Mysql5.7 is installed by default, root has a password.
Get MySQL Temporary Password
To enhance security, MySQL 5.7 randomly generates a password for the root user. In the error log, the location of the error log, if the RPM package is installed, is /var/log/mysqld.log by default.
The temporary password can only be viewed after mysql has been started once
#View original password grep 'temporary password' /var/log/mysqld.log #Add port 3306 to firewall exceptions and reboot firewall-cmd --zone=public --add-port=3306/tcp --permanent firewall-cmd --reload
#change Password ALTER USER 'root'@'localhost' IDENTIFIED BY 'eFeG20125'; #Authorize remote network access GRANT ALL PRIVILEGES ON *.* TO 'root'@'192.168.199.%' IDENTIFIED BY 'eFeG20125' WITH GRANT OPTION; flush privileges;
