![]() ![]() Because of this, it’s best to avoid using this account outside of administrative functions. This user has full privileges over the MySQL server, meaning it has complete control over every database, table, user, and so on. Upon installation, MySQL creates a root user account which you can use to manage your database. Step 3 - Creating a Dedicated MySQL User and Granting Privileges You can now move on to creating a dedicated database user with the MySQL client. Once the script completes, your MySQL installation will be secured. This will mean that you can once again connect to MySQL as your root user using the sudo mysql command. ALTER USER 'localhost' IDENTIFIED WITH auth_socket.Then go back to using the default authentication method using this command: To authenticate as the root MySQL user using a password, run this command: Note: Once the security script completes, you can then reopen MySQL and change the root user’s authentication method back to the default, auth_socket. If you elect to set up the Validate Password Plugin, any MySQL user you create that authenticates with a password will be required to have a password that satisfies the policy you select: The first prompt will ask whether you’d like to set up the Validate Password Plugin, which can be used to test the password strength of new MySQL users before deeming them valid. This will take you through a series of prompts where you can make some changes to your MySQL installation’s security options. ALTER USER 'localhost' IDENTIFIED WITH mysql_native_password BY ' password' Īfter making this change, exit the MySQL prompt:įollowing that, you can run the mysql_secure_installation script without issue.The following example changes the authentication method to mysql_native_password: Then run the following ALTER USER command to change the root user’s authentication method to one that uses a password. To avoid entering this recursive loop, though, you’ll need to first adjust how your root MySQL user authenticates. This will lead the script into a recursive loop which you can only get out of by closing your terminal window.īecause the mysql_secure_installation script performs a number of other actions that are useful for keeping your MySQL installation secure, it’s still recommended that you run it before you begin using MySQL to manage your data. Please consider using ALTER USER instead if you want to change authentication parameters. Failed! Error: SET PASSWORD has no significance for user as the authentication method used doesn't store authentication data in the MySQL server. This script changes some of the less secure default options for things like disallowing remote root logins and removing sample users. Step 2 - Configuring MySQLįor fresh installations of MySQL, you’ll want to run the database management system’s included security script. Because this leaves your installation of MySQL insecure, we will address this next. These commands will install and start MySQL, but will not prompt you to set a password or make any other configuration changes. To install it, update the package index on your server if you’ve not done so recently:Įnsure that the server is running using the systemctl start command: At the time of this writing, the version of MySQL available in the default Ubuntu repository is version 8.0.28. On Ubuntu 22.04, you can install MySQL using the APT package repository. To set this up, follow our initial server setup guide for Ubuntu 22.04. One Ubuntu 22.04 server with a non-root administrative user and a firewall configured with UFW.By completing it, you will have a working relational database that you can use to build your next website or application. ![]() ![]() This tutorial will go over how to install MySQL version 8.0 on an Ubuntu 22.04 server. It implements the relational model and uses Structured Query Language (better known as SQL) to manage its data. MySQL is an open-source database management system, commonly installed as part of the popular LAMP (Linux, Apache, MySQL, PHP/Python/Perl) stack. ![]()
