What is the default root pasword for MySQL 5.7

Question

Cannot login to MySQL database after fresh install with root ID and empty/no password like other older MySQL versions do

Answer 1

MySQL 5.7 or newer generates a default temporary password after fresh install.

To use MySQL first you would be required to get that password from the log file which is present at the /var/log/mysqld.log. So follow the following process:

1. grep 'temporary password' /var/log/mysqld.log

2. mysql_secure_installation

The second command is required to change the password for MySQL and also to make certain other changes like removing temporary databases, allow or disallow remote access to root user, delete anonymous users etc…
