Summary: in this tutorial, you will learn how to stop MySQL Server on Windows and Linux.

On Windows, you can stop MySQL Server using the program mysqladmin.

The program mysqladmin locates in the folder <path_to_installation_dir>\bin, where path_to_installation_dir is the path to the installation directory e.g., C:\Program Files\MySQL\MySQL Server 8.0\

Typically, you should add the pathname of the MySQL bin directory to Windows path environment variable to access any MySQL programs in the bin directory faster.

To stop MySQL, you follow these steps:

First, launch the Command Prompt by pressing Windows+R to open the Run box and type cmd and press Enter.

Second, navigate to the bin folder of the MySQL if it is not in the Window path environment.

Third, use the following command to stop MySQL Server:

mysqladmin -u root -p shutdown Enter password: ********

It prompts for a password of the root account. You need to enter the password and press the Enter keyboard.

The program will stop the MySQL Server.

Stop MySQL Server on Linux

To stop MySQL Server on Linux, you use the following command:

/etc/init.d/mysqld stop

Some Linux distributions provide server command:

service mysqld stop

Or

service mysql stop

In this tutorial, you have learned how to stop MySQL Server on Windows and Linux.

This article describes the process of resolving the following MySQL® for Windows® error:

MySQL service on local computer started and then stopped. Some services stop automatically if they are not in use by other services or programs.

The solution varies depending on your version of MySQL. Attempt the solutions in the order of the following sections.

Restart the service

Restart the MySQL service by running the following command:

mysqld --initialize

You need to log in as root or use sudo -i to run this command.

Reinstall the service

Log in as root and reinstall the MySQL service by running the following commands:

mysqld --install
mysqld --initialize

Verify the my.ini config file

Certain versions of MySQL add invalid hex values at the beginning of the my.ini configuration file. Deleting the first three hex values using a hex editor should resolve this issue. This occurs because of an issue with a script line. The line specifies that each file must have a unique ID, which then appends the byte order to mark the text file.

If you have a backup of the original my.ini file, you can copy the contents of this file and manually paste them onto the current my.ini to resolve this issue.

Verify the Network Service permissions

You might need to verify that the Network Service has the proper permissions. Use the steps in this section to verify these permissions are correct:

Right-click the Data folder.
Select Properties.
Select the Security tab.
Click Advanced.
Click Change Permissions….
Click Add….
Enter NETWORK SERVICE.
Click Check Names.
Click OK.
Select Full Control.

Check for missing default files

It’s possible that default files are missing. Use the steps in this section to check for this missing default files:

Open the command prompt.

Go to the MySQL *bin* and run the following command:

mysqld --defaults-file="C:\Program Files\MySQL\MySQL Server 5.0\my.ini" --standalone --console

If it specifies a missing default folder, you should create a new default file.
