MySQL 5.5 Database Installation Guide103

MySQL is a popular open-source relational database management system (RDBMS) that is widely used for storing and managing data in various applications. This tutorial provides step-by-step instructions on how to install MySQL 5.5 database on a Linux-based system.

Prerequisites

Before you begin the installation process, ensure that your system meets the following prerequisites:* Operating System: Linux (tested on Ubuntu 20.04)
* CPU: 1 GHz or higher
* RAM: 1 GB or higher
* Hard Disk Space: 500 MB or higher

Step 1: Add MySQL Repository

Add the official MySQL repository to your system's sources list using the following command:```
sudo apt-get update
sudo apt-get install software-properties-common
sudo add-apt-repository ppa:mysql/mysql-5.5
sudo apt-get update
```

Step 2: Install MySQL Server

Once the repository is added, install the MySQL server package using the following command:```
sudo apt-get install mysql-server
```

Step 3: Configure MySQL

After the installation is complete, configure MySQL by running the following command:```
sudo mysql_secure_installation
```

This command will guide you through a series of prompts to secure your MySQL installation. It will ask you to set a root password, remove anonymous users, disallow root login from remote hosts, and reload the privilege tables.

Step 4: Start MySQL Server

Start the MySQL server using the following command:```
sudo service mysql start
```

Step 5: Connect to MySQL

Connect to the MySQL server as the root user using the following command:```
sudo mysql -u root -p
```

You will be prompted to enter the root password you set during the configuration step.

Step 6: Create a New Database and User

Create a new database and user by executing the following commands:```
CREATE DATABASE my_database;
GRANT ALL PRIVILEGES ON my_database.* TO 'my_user'@'localhost' IDENTIFIED BY 'my_password';
FLUSH PRIVILEGES;
```

Replace "my_database", "my_user", and "my_password" with your desired values.

Step 7: Use the Database

To use the newly created database, execute the following command:```
USE my_database;
```

You can now create tables, insert data, and perform various database operations within the "my_database" database.

Additional Notes

Here are a few additional notes to consider:* You can check the status of the MySQL server using the command "sudo service mysql status".
* To stop the MySQL server, use the command "sudo service mysql stop".
* To restart the MySQL server, use the command "sudo service mysql restart".
* You can find more detailed MySQL documentation on the official MySQL website.

Conclusion

Congratulations, you have successfully installed and configured MySQL 5.5 database on your Linux system. You can now create databases, tables, and manage data effectively using MySQL.
