Find MySQL 5.7 root password

Unlike previous versions, by default MySQL 5.7 automatically creates a temporary root password. And if you come from previous MySQL versions you should know that on the old versions you were the one that was in charge of configuring the mysql root password.

CentOS/RedHat Users

If you are using Centos/Redhat MySQL rpm based installation, the root password was set at the installation time. MySQL 5.7 root password must be stored inside your MySQL error log.

Now that you know your MySQL error log path, let’s see if the MySQL 5.7 root password is there or not. Let’s grep it.

Debian/Ubuntu Users

Unlike on CentOS/RHEL, you will be prompted to set the root password, if you do, you already know the password. Now, if you don’t set it up when prompted, then MySQL will be created without any root password.  It is recommended to setup a root password asap.

At the logs you will see something like this:

[Warning] root@localhost is created with an empty password ! Please consider switching off the --initialize-insecure option.

How can I get MySQL root password if I don’t have an error log?

Let’s suppose you lost your error log, it was removed by mistake or any other reason. Then you can start MySQL server using the –skip-grant-tables option, that will allow you to login to the MySQL shell and reset the root password safely.


MySQL 5.7 introduces lot of ways to improve server security, however in this case this missing root password thing has been causing lot of confusion among MYSQL server users.
