Uninstalling MySQL on Ubuntu 18.04 can be done using a variety of methods, including the command line and the Ubuntu Software Center. In this article, we will go over the steps to uninstall MySQL using the command line and provide code examples to help you along the way.
First, it is important to note that uninstalling MySQL will remove all of your databases, so it is recommended to make a backup of your data before proceeding.
To uninstall MySQL using the command line, the first step is to stop the MySQL service. You can do this by running the following command:
sudo service mysql stop
Next, you will need to remove the MySQL packages from your system. You can do this by running the following command:
sudo apt-get remove --purge mysql-server mysql-client mysql-common
This command will remove the MySQL server, client, and common packages from your system, effectively uninstalling MySQL.
It is also necessary to remove any remaining MySQL configuration files. You can do this by running the following command:
sudo apt-get autoremove
sudo apt-get autoclean
This command will remove all remaining MySQL files from your system.
Finally, to ensure that MySQL is completely uninstalled and that no remnants of the software remain on your system, you can run the following command:
sudo apt-get remove --purge mysql-server-5.7
This command will completely remove MySQL and all of its components from your system, including configuration files and data.
It's important to note that the above command assumes that you have MySQL version 5.7 installed on your system. If you have a different version, you will need to adjust the command accordingly.
In conclusion, uninstalling MySQL on Ubuntu 18.04 can be done by stopping the service, removing the packages, removing remaining configuration files, and then completely removing the software and all of its components. It is important to backup your data before proceeding with the uninstallation process.
In addition to uninstalling MySQL, it's also important to understand how to install and configure the software on Ubuntu 18.04.
To install MySQL on Ubuntu 18.04, you can use the apt package manager. The first step is to update the package index by running the following command:
sudo apt-get update
Next, you can install MySQL by running the following command:
sudo apt-get install mysql-server
This command will install the MySQL server and all necessary dependencies. During the installation process, you will be prompted to set a root password for the MySQL server. It's important to choose a strong and secure password to protect your data.
Once the installation is complete, you can start the MySQL service by running the following command:
sudo service mysql start
It's also important to secure your MySQL installation by running the security script that comes with the package:
sudo mysql_secure_installation
This script will help you to configure some security options such as disabling the remote root login, removing test database, and reload privilege tables.
Once MySQL is installed, you can start using it to create and manage databases. The MySQL command line client, also known as the MySQL shell, can be used to interact with the database server. You can access the MySQL shell by running the following command:
mysql -u root -p
You will be prompted for the root password that you set during the installation process. Once you are logged in, you can use SQL commands to create and manage databases and tables.
In addition to the command line, there are also many graphical tools available for managing MySQL databases, such as phpMyAdmin and MySQL Workbench. These tools provide a user-friendly interface for creating and managing databases, and are useful for both developers and administrators.
In conclusion, uninstalling MySQL on Ubuntu 18.04 is a straightforward process, but it's important to backup your data before proceeding. Additionally, it's important to understand how to install and configure MySQL, as well as how to use tools for managing and interacting with the database.
