MySQL 8.0.12 decompression version installation graphic tutorial under Windows 10

This article records the installation graphic tutorial of MySQL 8.0.12 decompression version for your reference. The specific content is as follows

Installation environment: Window10 Home Edition, 64-bit

Database: MySQL 8.0.12 64-bit

Installation method: Compressed package installation

Installation steps:

1. Download the installation package

Download the latest installation package from the MySQL official website: Official website address

Simply click "No thanks, just start my download." at the bottom to start downloading

Download the compressed package successfully

Note: When installing the database, the logged-in user must have Administrator privileges.

2. Unzip the compressed package and put it in the directory to be installed

The file structure after decompression is as follows:

From the unzipped file structure, we can see that there is no my.ini configuration file in it, so we need to create the my.ini configuration file ourselves.

3. Create the my.ini configuration file

# Database server configuration items [mysqld]
# Database path basedir=D:\\Programs\\MySQL\\MySQL-8.0.12-winx64
#Data path datadir=D:\\Programs\\MySQL\\data
#Port number port=3306
# Default character set character-set-server=utf8mb4
# Storage engine default-storage-engine=INNODB

# Client configuration items [mysql]
#Default character set default-character-set=utf8mb4

#Connection client configuration item [client]
default-character-set=utf8mb4

After the configuration file is created, you can proceed to the next step of installation.

4. Initialize MySQL using operation instructions

Open the terminal and go to the bin directory under the data installation path:

Enter the command "mysqld –initialize –console" in the terminal and press Enter to complete the initialization:

Note: After the initialization is completed, do not close the window, because the password of the root user will be generated here. The "p=brffHdg4T5" in the figure is the random password.

Of course, there is another initialization method that does not generate a random password, but you still need to set a password before officially using the database. The initialization command is "mysqld –initialize-insecure –console". When the database is initialized without a random password, you need to use "mysql -u root --skip-password" when logging in for the first time, that is, skip the password verification method to log in.

5. Database service installation

After the database is initialized, you can register the data as a Windows service, so that you can start the database as a service.
Open the terminal and go to the bin directory under the data installation path, as shown in Figure 1 in step 4.
Use the command "mysqld –install" to complete the installation of the service:

Note: When registering the service, be sure to use administrator privileges, otherwise the installation of the service will be rejected.

At the same time, you can also use the command "mysqld –remove" to remove the registered service.

In fact, the complete command for registering a service is “mysqld –install service name”. If the service name is not written, the default is “MySQL”. The service removal command is also “mysqld –remove service name”, and the default value is “MySQL”.

6. Service startup

Use the command "NET start MySQL" in the terminal to start the database service:

Verify that the service has been started. Try to log in to the database on the terminal page. The password you need to enter here is the random password generated by the system during initialization in step 4 Figure 2. Just enter it:

Login successful! Before executing the command, the system will force you to change the random password used during initialization:

Use the command "ALTER USER 'root'@'localhost' IDENTIFIED BY 'my_new_psd';" and press Enter:

After changing the password, you can use the database normally!

Use the client tool to connect to the database:
