Laravel is a very popular development framework in PHP. It provides developers with a series of efficient, easy-to-use and feature-rich development tools, as well as a convenient support system. During the development process of Laravel, we usually use MySQL as the database service. However, sometimes we need to shut down the MySQL service and perform some related operations. So, this article will introduce you to how to shut down MySQL in Laravel.

First of all, we need to configure the MySQL database connection in Laravel to ensure that it can be used normally. In Laravel 5.5 and above, this configuration file is config/database.php, and in Laravel 5.4 and below, this configuration file is the .env file.

For the config/database.php file, we can find the mysql configuration in the connections array and modify it as needed. Common configurations Items include host, port, database, username, password, etc. For example:

'connections'?=>?[

????'mysql'?=>?[
????????'driver'?=>?'mysql',
????????'host'?=>?env('DB_HOST',?'localhost'),
????????'port'?=>?env('DB_PORT',?'3306'),
????????'database'?=>?env('DB_DATABASE',?'forge'),
????????'username'?=>?env('DB_USERNAME',?'forge'),
????????'password'?=>?env('DB_PASSWORD',?''),
????????'charset'?=>?'utf8mb4',
????????'collation'?=>?'utf8mb4_unicode_ci',
????????'prefix'?=>?'',
????????'strict'?=>?true,
????????'engine'?=>?null,
????],

],

For the .env file, you need to configure MySQL related environment variables in it, for example:

DB_CONNECTION=mysql
DB_HOST=localhost
DB_PORT=3306
DB_DATABASE=homestead
DB_USERNAME=homestead
DB_PASSWORD=secret

Once the connection is configured correctly, we can php artisan migrate command to migrate the database. This command will execute all migration files in the database/migrations directory in sequence and import the defined database structure into MySQL.

So, what should we do when we need to shut down the MySQL service? In fact, closing MySQL does not require special Laravel commands or APIs, but can be done directly using system commands.

In Linux systems, we can use the systemctl command to manage the MySQL service. For example, the command to start the MySQL service is:

sudo?systemctl?start?mysql

and the command to close the MySQL service is:

sudo?systemctl?stop?mysql

Of course, if you are using a Mac or Windows operating system, then the command to close the MySQL service is: The methods are also different. For Mac users, you can start and shut down the MySQL service through the following commands:

sudo?/usr/local/mysql/support-files/mysql.server?start
sudo?/usr/local/mysql/support-files/mysql.server?stop

For Windows users, you need to perform related operations in service management. The specific method is: enter the services.msc command in the Windows search box, open the "Services" page, find the MySQL service in the list, right-click and select "Stop".

In general, shutting down the MySQL service is not a particularly complicated operation, and the use of Laravel relies on the normal operation of the MySQL service. If you need to perform related operations on Laravel, it is recommended to back up the database first and close the MySQL service before making modifications. Of course, before closing the MySQL service, you can also use some APIs provided by Laravel to determine whether the MySQL service is currently running, so that related operations can be performed more safely.

Finally, let’s summarize the method of closing MySQL in Laravel described in this article. For Linux users, you can use the systemctl command to manage the MySQL service and complete related operations; for Mac users, you can use the mysql.server command to shut down the MySQL service; for Windows users, you need Proceed further in Service Management. No matter which method is used, it is recommended to back up the database first and close the MySQL service before making relevant modifications.
