After the installation package is decompressed, it is as follows: you can put it in other folders at will
After decompressing to C drive, there will be a file named C:\Program Files\mysql-8.0.16-winx64. Click to enter to view the subdirectories under this folder as follows:
The black cmd window is called up under the windows system, prompting it is best to open it as an administrator, and enter the subdirectory bin in the MYSQL installation directory just now in the command line mode, C:\Program Files\mysql-8.0.16-winx64\bin directory Below, as shown in the figure:
Then enter the installation command mysqld -install in the C:\Program Files\mysql-8.0.16-winx64\bin directory. It is relatively simple and I will not take a screenshot. If there is an error, please open the black window as an administrator.
The execution will generate a data folder in the MYSQL decompression directory C:\Program Files\mysql-8.0.16-winx64, which contains a file ending with the suffix .err. This file contains the first time you use MYSQL A temporary random password is generated. Open this .err file with Notepad, you can find the random password, (root@localhost:'password') 2 You can also execute mysqld --initialize --console to generate a random password, which will be printed to the console and saved in a place
Then configure the MYSQL startup file, create a new .ini format file my.ini under the MYSQL decompression directory C:\Program Files\mysql-8.0.16-winx64, and then open it in Notepad format and write the following code: just copy paste save note down your path to change
[mysqld]
# Set 3306 port
port=3306
# Set mysql installation directory
basedir=C:\Program Files\mysql-8.0.16-winx64

datadir=C:\Program Files\mysql-8.0.16-winx64\Data
# Allow the maximum number of connections
max_connections=200
# Allow the number of connection failures. This is to prevent someone from attempting to attack the database system from this host
max_connect_errors=10
# The character set used by the

Then enter the following command in the bin directory:
mysqld -install service name (custom, you can use mysql8, mysql)
Start the service:
net start mysql
Log in to MySQL: The password is the random password above
mysql -u root -p
