Foreword:

After the MySQL installation is complete, you need to start the service process, otherwise the client cannot connect to the database.In the previous configuration process, MySQL has been installed as a Windows service. When Windows starts, the MySQL service will also start along with it. However, sometimes it is necessary to manually control the start and stop of the MySQL service, which can be achieved in two ways.

1. Through Windows Service Manager

Start the MySQL service You can check whether the MySQL service is enabled through the Windows service manager. First, click the "Start" menu, select the "Run" command in the pop-up menu, open the "Run" dialog box and enter the services.msc command,Click the "OK" button to open the Windows Service Manager, as shown in Figure 1-26.

As can be seen from Figure 1-26, the MySQL service is not started. At this time, you can directly double-click the MySQL service item to open the properties dialog box, and click the "Start" button to modify the status of the service, as shown in Figure 1-27 shown.

There is an option for startup type in Figure 1-27, there are three types of options to choose from, as follows.

(1) Automatic: Services that are usually closely related to the system must be set to automatic, and it will be started with the system.

(2) Manual: The service will not be started with the system and will not be activated until needed.

(3) Disabled: The service will no longer start, even when it is needed, unless modified to the above two types.For the above three situations, beginners can choose according to their actual needs. It is recommended to choose "automatic" or "manual" here.

2. Start MySQL service through DOS command

Starting the MySQL service can be started not only through Windows Service Manager, but also through DOS commands.The specific command to start the MySQL service through the DOS command is as follows:

net start mysql
After executing the above command, the displayed result is shown in Figure 1-28.

If it prompts "The service name is invalid", check the name of the Mysql service installed locally, and check it:

Computer - Right Click - Manage - Services and Applications - Services

Find the Mysql service name.

My local Mysql service name is Mysql55.

The startup command is: net start mysql55
