To delete a database, enter: DROP DATABASE database_name įor more about working with MySQL databases, see the MySQL docs.To create a new database, enter: CREATE DATABASE database_name.To see what databases you have available, in the MySQL prompt, enter: SHOW DATABASES.To open the MySQL prompt, enter: sudo mysql.Start MySQL Server / check status: systemctl status mysql.Confirm installation and get the version number: mysql -version.Once the packages have updated, install MySQL with: sudo apt install mysql-server.Open your Ubuntu command line and update the packages available: sudo apt update.You may need to first enable systemd support in your wsl.conf configuration file. To install MySQL on a Linux distribution running on WSL, just follow the Installing MySQL on Linux instructions in the MySQL docs. It uses key-value pairs for storage instead of documents. Redis is is an open-source NoSQL in-memory data structure store. It's good for flexibility and unstructured data, and caching real-time analytics. It is horizontally scalable, which means multiple smaller machines will do the work for you. MongoDB is an open-source NoSQL document database designed to work with JSON and store schema-free data. SQLite is an open-source self-contained, file-based, “serverless” database, known for its portability, reliability, and good performance even in low-memory environments. These are also relational database management systems set up on servers with primary function of storing and retrieving data as requested by software applications.

It is currently the most widely used of the four database systems. It is vertically scalable, which means one ultimate machine will do the work for you. MySQL is an open-source SQL relational database, organizing data into one or more tables in which data types may be related to each other. Some popular choices for a database system include: Install a Linux distribution using WSL and create a Linux user name and password.Running Windows 11 or Windows 10, updated to version 2004, Build 19041 or later.Get started with MySQL, PostgreSQL, MongoDB, Redis, Microsoft SQL Server, or SQLite. This step-by-step guide will help you get started connecting your project in WSL to a database. ![]()
