Database management is one of the most common tasks in small, medium and large companies since these allow a much more detailed and direct control over the data that should be recorded, as well as the structure that should be given to same.
Although there are several options at the database level, one of the most popular and used by thousands of administrators is MySQL which allows us to have a SQL database server (Structured Query Language) with functions and outstanding features such as security, access speed, scalability, support of multiple users and execution of various processes simultaneously.
When setting up a MySQL server , independent of the operating system used, it is natural that with the passage of time and when adding more and more tables and bases, at some point MySQL can generate some type of error either loading the databases, accessing to the queries or generating execution errors, if this happens to you, in TechnoWikis we give you a practical tip that will help you to refresh MySQL and is to stop or restart the MySQL services and thus be able to work in a complete and integral way with the bases created.
MySQL service startup
Let's see 3 options depending on your version.
/etc/init.d/mysqld start service mysqld start service mysql start
Stop the MySQL service
We have 3 options depending on the version.
/etc/init.d/mysqld stop service mysqld stop service mysql stop
Restart the MySQL service
/etc/init.d/mysqld restart service mysqld restart service mysql restart
You will learn to perform this process simply on macOS, Linux and Windows.
