MySQL is a popular open-source relational database management system that is widely used in web development and other applications. When setting up a new MySQL installation on Ubuntu 20.04, one important step is to set a root password to secure your database. In this tutorial, we will walk you through the steps to set the MySQL root password on Ubuntu 20.04.
Step 1: Open the terminal on your Ubuntu 20.04 system by pressing Ctrl+Alt+T or searching for "Terminal" in the application launcher.
Step 2: Once the terminal is open, log in to the MySQL root account by running the following command:
"`
sudo mysql -u root
"`
Step 3: After entering the MySQL shell, run the following command to set a new password for the root user:
"`
ALTER USER ‘root’@’localhost’ IDENTIFIED WITH mysql_native_password BY ‘new_password’;
"`
Replace `’new_password’` with the password you want to set.
Step 4: Finally, flush the privileges to apply the changes by running the command:
"`
FLUSH PRIVILEGES;
"`
Step 5: Exit the MySQL shell by typing:
"`
EXIT;
"`
Congratulations! You have successfully set the root password for MySQL on Ubuntu 20.04.
Now let’s take a look at the pros and cons of setting the MySQL root password:
Pros | Cons |
---|---|
1. Enhances security by requiring a password for root access. | 1. May require additional steps for password recovery in case of a forgotten password. |
2. Protects sensitive data and prevents unauthorized access to the MySQL server. | 2. If the root password is weak or compromised, it could lead to security vulnerabilities. |
3. Allows for better control over who can access and modify the MySQL database. | 3. Users may forget the root password, leading to potential access issues. |
By following these steps, you can enhance the security of your MySQL installation by setting a root password on Ubuntu 20.04. Remember to choose a strong and secure password and ensure you keep it in a safe place to prevent any access issues.

How do I allow root login in MySQL?
Enabling root login in MySQL involves a few steps. Here’s a straightforward walkthrough:
Step 1: Log in to the MySQL server using a privileged account such as the root user or an account with administrative privileges.
Step 2: Access the MySQL shell by entering the following command:
"`
mysql -u root -p
"`
You will be prompted to enter the password for the root user.
Step 3: Once inside the MySQL shell, run the following command to allow the root user to log in from any host:
"`
ALTER USER ‘root’@’%’ IDENTIFIED WITH mysql_native_password BY ‘your_password’;
"`
Replace `’your_password’` with the desired password for the root user. This command sets the authentication plugin to `mysql_native_password`, which is compatible with older MySQL clients.
Step 4: Next, run the following command to grant all privileges to the root user:
"`
GRANT ALL PRIVILEGES ON *.* TO ‘root’@’%’;
"`
This grants full privileges to the root user on all databases and tables in the MySQL server.
Step 5: Finally, apply the changes by running the following command:
"`
FLUSH PRIVILEGES;
"`
This ensures that the server reloads the grant tables and applies the new privileges.
That’s it! You have now enabled root login in MySQL, allowing the root user to access the database from any host. Keep in mind that granting root access from any host can have security implications, so it’s essential to take necessary precautions to protect your server.
How to set password to root in MySQL?
To set a password for the root user in MySQL, follow these steps:
1. Log in to MySQL as the root user: Open your command prompt or terminal and type the following command:
"`
mysql -u root -p
"`
You will be prompted to enter the root user’s password. If this is your first time accessing MySQL, you might not have a password yet, so you can proceed without entering a password.
2. Once logged in, switch to the "mysql" database: Enter the following command in the MySQL prompt:
"`
USE mysql;
"`
3. Now, you can change the password for the root user. Run the following command:
"`
ALTER USER ‘root’@’localhost’ IDENTIFIED WITH mysql_native_password BY ‘new_password’;
"`
Replace ‘new_password’ with the password you want to set for the root user. Make sure to choose a strong and secure password.
4. Flush the privileges to ensure the changes take effect:
"`
FLUSH PRIVILEGES;
"`
That’s it! You have successfully set a password for the root user in MySQL.
Note: It is essential to protect your MySQL database by setting a strong password for the root user. This helps to safeguard your system from unauthorized access and potential security breaches. Remember to keep your password confidential and avoid using common or easily guessable passwords. Regularly updating your password is also a good practice to enhance security.

What is default MySQL root password Ubuntu?
As a tech blogger, I can provide you with guidance on the default MySQL root password in Ubuntu without mentioning that I am an technical blogger.
By default, when installing MySQL on Ubuntu, there is no specific password set for the MySQL root user. Instead, the root user is authenticated using the system’s root authentication credentials. This means that you can log in to the MySQL server as the root user without specifying a password.
However, it is highly recommended to set a password for the MySQL root user to enhance security. To set a password, you can follow these steps:
1. Open a terminal or SSH into your Ubuntu server.
2. Log in to the MySQL server as the root user by running the following command:
"`
sudo mysql -u root
"`
3. Once you are logged in to the MySQL shell, use the following command to set a password for the root user:
"`
ALTER USER ‘root’@’localhost’ IDENTIFIED WITH mysql_native_password BY ‘your_password’;
"`
Replace `’your_password’` with your desired secure password.
4. After setting the password, run the following command to apply the changes immediately:
"`
FLUSH PRIVILEGES;
"`
5. Finally, you can exit the MySQL shell by typing `exit` and pressing Enter.
Please note that it is important to choose a strong and unique password to protect your MySQL server from unauthorized access. Remember to keep your password secure and consider using a password manager to store it safely.
Why is MySQL not asking for password in Ubuntu?
MySQL not asking for a password in Ubuntu can be due to several reasons, such as the database configuration, user privileges, or authentication methods. Here are some possible explanations:
1. MySQL is configured to use an authentication method that does not require a password.
– By default, MySQL can use different authentication methods, including password-based authentication, but it’s possible to configure it to use other methods such as native authentication, Kerberos, or SSL certificates. In such cases, a password may not be required.
2. The MySQL user has been granted access without a password.
– It’s possible that during the creation of a MySQL user, no password was set for that user or the user was granted privileges without requiring a password. This can be checked by inspecting the user accounts and their associated privileges.
3. MySQL configuration file has been modified.
– The MySQL configuration file, typically located at `/etc/mysql/my.cnf`, can be modified to change the default behavior. It’s possible that the authentication settings have been altered, allowing MySQL to start without prompting for a password.
4. MySQL server is running in an insecure mode.
– In some cases, the MySQL server might be running in an insecure mode, where it allows access without authentication. This is generally not recommended for production environments but might be set up for development or testing purposes.
To address the issue and enable password authentication:
1. Update the MySQL configuration file.
– Open the MySQL configuration file, usually located at `/etc/mysql/my.cnf`, and ensure that the `skip-grant-tables` configuration option is commented out or removed. This option is used to start the server without using password authentication, and its presence could be the reason why MySQL is not asking for a password.
2. Verify user privileges and password settings.
– Use the `mysql` command-line tool or a MySQL client to connect to the MySQL server. Check the `mysql.user` table to ensure that the specific user account you are using requires a password for authentication. If required, set or update the password for the user.
3. Restart the MySQL server.
– After making any changes to the configuration file or user settings, restart the MySQL server using the appropriate command, such as `sudo service mysql restart`.
Remember to follow best practices for securing your MySQL installation by using strong passwords and appropriate access controls to ensure the safety of your database.
