Subsubstep 2.1.2: Install the Repository Package
Install the downloaded repository package using the dpkg command.
After downloading the MySQL repository package, it’s time to install it on your Ubuntu 20.04 system. To do this, you will use the dpkg command, which is the package manager for Debian-based systems like Ubuntu.
To install the repository package, open a terminal and navigate to the directory where the package is located. Then, run the following command:
sudo dpkg -i package_name.deb
Replace “package_name.deb” with the actual name of the downloaded repository package. This command will install the package and its dependencies on your system.
Once the installation is complete, you can proceed to the next step of installing the MySQL server on your Ubuntu 20.04 system.
Substep 2.2: Installing MySQL Server
After adding the repository, it’s time to install the MySQL server on your Ubuntu 20.04 system. Installing MySQL is a straightforward process that can be done using the apt package manager. Simply open a terminal and run the following command:
sudo apt install mysql-server
This command will download and install the MySQL server package along with any necessary dependencies. During the installation, you will be prompted to set a root password for the MySQL server. Make sure to choose a strong password to secure your database.
Once the installation is complete, you can start using MySQL on your Ubuntu 20.04 system. To verify that the installation was successful, you can run the following command to check the status of the MySQL service:
sudo systemctl status mysql
If the service is active and running, you are ready to start using MySQL to create and manage databases on your Ubuntu 20.04 system.
Step 3: Securing MySQL
Step 3: Securing MySQL
Securing your MySQL installation is crucial to protect your data and prevent unauthorized access. By following these steps, you can ensure that your MySQL server is safe and secure.
To start, you need to set a root password for your MySQL installation. This password will be required whenever you want to perform administrative tasks or make changes to your database. Make sure to choose a strong password that is difficult to guess.
In addition to setting a root password, it is important to remove unnecessary default settings that could potentially pose security risks. These settings include anonymous user accounts and test databases. By removing these, you reduce the chances of unauthorized access to your MySQL server.
By taking these security measures, you can have peace of mind knowing that your MySQL installation is protected and your data is secure.
Substep 3.1: Running the MySQL Secure Installation
Substep 3.1: Running the MySQL Secure Installation
To ensure the security of your MySQL installation, it is crucial to run the MySQL secure installation script. This script will guide you through the process of configuring the root password and removing any insecure default settings.
Here are the steps to execute the MySQL secure installation:
- Open your terminal and log in as the root user or a user with sudo privileges.
- Enter the following command to start the secure installation script:
sudo mysql_secure_installation
The script will prompt you to enter the root password, which is initially blank. Set a strong password to protect your MySQL server from unauthorized access.
During the script, you will be asked to remove anonymous users, disallow remote root login, remove test databases, and reload privilege tables. It is recommended to answer ‘Y’ (yes) to all these prompts for enhanced security.
Once the script finishes, your MySQL installation will be secured with a strong root password and the removal of insecure defaults.
Substep 3.2: Testing the MySQL Installation
Once you have successfully installed MySQL on your Ubuntu 20.04 system, it is crucial to test the installation to ensure everything is working correctly. This can be done by logging in and accessing the MySQL shell.
To log in to the MySQL shell, open a terminal and enter the following command:
mysql -u root -p
This command will prompt you to enter the root password that you set during the MySQL secure installation process. After entering the password, press Enter.
Once you are logged in to the MySQL shell, you can start running MySQL commands and interacting with the database. This is where you can create databases, tables, and perform various operations on your MySQL server.
By successfully logging in and accessing the MySQL shell, you can be confident that your MySQL installation on Ubuntu 20.04 is working correctly and ready for use.
Step 4: Managing MySQL
Step 4: Managing MySQL
Once you have successfully installed MySQL on your Ubuntu 20.04 system, it’s time to dive into managing your MySQL server. This step will introduce you to some essential commands and tools that will help you effectively manage your MySQL server.
One of the key tasks in managing MySQL is starting and stopping the MySQL service. You can use systemd commands to easily start, stop, and restart the MySQL service. For example, to start the MySQL service, you can use the following command:
sudo systemctl start mysql
In addition to starting and stopping the service, you will also learn how to create and manage databases in MySQL. This includes creating users, granting privileges, and managing database permissions. By understanding these concepts, you will have greater control over your MySQL server and ensure the security and integrity of your data.
Furthermore, there are various tools available that can simplify the management of your MySQL server. These tools provide graphical interfaces and command-line interfaces to perform tasks such as database administration, data backup and restore, and performance monitoring. Some popular tools include phpMyAdmin, MySQL Workbench, and Percona Toolkit.
By exploring these essential commands and tools, you will become proficient in managing your MySQL server on Ubuntu 20.04, ensuring smooth operations and optimal performance.
Substep 4.1: Starting and Stopping MySQL Service
Starting and stopping the MySQL service is an essential part of managing your MySQL server on Ubuntu 20.04. To accomplish this, you can use systemd commands, which provide a convenient way to control services in a Linux system.
To start the MySQL service, you can use the following command:
sudo systemctl start mysql
This command will initiate the MySQL service and make it accessible for connections. If the service is already running, it will display a message indicating that the service is already active.
If you need to stop the MySQL service, you can use the following command:
sudo systemctl stop mysql
This command will halt the MySQL service, terminating all active connections and preventing new connections from being established.
In some cases, you may need to restart the MySQL service to apply changes or resolve certain issues. To restart the MySQL service, you can use the following command:
sudo systemctl restart mysql
This command will stop the MySQL service if it is running and then start it again, ensuring that any changes or configurations take effect.
By using these systemd commands, you can easily start, stop, and restart the MySQL service on your Ubuntu 20.04 system, allowing you to effectively manage your MySQL server.
Substep 4.2: Creating and Managing MySQL Databases
Creating and managing databases in MySQL is an essential skill for any MySQL user. By understanding how to create databases, you can organize your data efficiently and ensure optimal performance. Additionally, managing users and granting privileges allows you to control access to your databases and protect sensitive information.
To create a database in MySQL, you can use the CREATE DATABASE statement followed by the desired database name. For example, to create a database called “mydatabase”, you would execute the following command:
CREATE DATABASE mydatabase;Once the database is created, you can start managing it by executing various commands such as creating tables, inserting data, and running queries.
When it comes to managing users and granting privileges, MySQL provides a robust set of commands. To create a new user, you can use the CREATE USER statement followed by the username and password. For example:
CREATE USER 'myuser'@'localhost' IDENTIFIED BY 'mypassword';After creating the user, you can grant specific privileges to the user on a particular database or table using the GRANT statement. For example, to grant all privileges to the user “myuser” on the database “mydatabase”, you would execute:
GRANT ALL PRIVILEGES ON mydatabase.* TO 'myuser'@'localhost';By understanding how to create and manage databases in MySQL, you can take full control of your data and ensure the security and efficiency of your MySQL server.
