MySQL is a popular open-source relational database management system (RDBMS) used for a wide range of applications, from small personal websites to large enterprise systems. It is known for its speed, reliability, and scalability. To use MySQL, it must first be installed on the system.
There are several ways to check if MySQL is installed on a Linux system. One way is to use the command which mysql. If MySQL is installed, the command will return the path to the MySQL executable. Another way is to use the command mysql --version. If MySQL is installed, the command will return the version of MySQL that is installed.
