Also checks the password against a dictionary of common passwords.Also requires a mixed case password with numbers and symbols.Simply enforces a minimum password length of 8 characters.There are three levels of increasing complexity provided. Next you’ll be asked what level of password validation to enable. I recommend turning this on, so type Y at the prompt.

The first step in the configuration asks whether you want to enable password validation. To run it, type the following at the terminal: sudo mysql_secure_installation Luckily, the mysql_secure_installation command launches an interactive tool which walks us through each of these steps. In order to ensure that your new server is secure, we’ll need to change the password for the root user and disable some standard testing features which are enabled for installation purposes. Step 2: Run mysql_secure_installation to secure your server To secure your new database server, let’s move on to the next section. This will install MySQL onto your server, but not all of the default settings on new installations are very secure. Next, run the following command to start the installation of MySQL: sudo apt-get install mysql-server After a minute or two, you’ll be returned back to the prompt and your package index will be up to date. ![]() Since we are using sudo to run this with superuser privileges, you’ll be prompted for your password before the package listings are downloaded. In order to update the package index, run the following command at the terminal: sudo apt-get update In Ubuntu, we can use the APT package manager to install MySQL but before we do so we need to check that the index of packages on our server is up to date. Otherwise, we’ll be installing all the other software we need. These same instructions should also work for other recent Ubuntu releases, and recent Debian releases. This guide assumes that you have a fresh install of Ubuntu 20.04, with all the latest updates applied. Beyond the scope of this walkthrough (but equally important) are the subsequent steps of creating a database, building tables, populating them with data, and querying your data. This guide walks you through the three basic steps of installing MySQL server on a new system: installing MySQL, configuring the security options on MySQL, and creating a new user to use MySQL with. Step 2: Run mysql_secure_installation to secure your server.
