[MySQL] About the installation of MySQL

One: Download MySQL

       Official website address: https://www.mysql.com/   Find the content of the following interface

         

2. Unzip the downloaded file and configure the ini file

                   

     The content of my.ini: as follows (the installation directory and storage directory are subject to your own.)

[mysqld]
# 设置3306端口

Three, initialize MySQL

      Open the command prompt with administrator privileges , use the command to enter the MySQL bin path

//我安装的目录在D盘下，根据自己的安装目录写地址
cd /d D:\MySQL\mysql-8.0.20-winx64\mysql-8.0.20-winx64\bin

                                                         

                     

      Then execute the following command:

mysqld --initialize --console

   Show the interface to indicate that the command is executed successfully. At this time, there will be an initial password, which must be recorded, and the password should be twelve digits, root@localhost: the rest are passwords. Make a record to facilitate the modification of the password later.

Fourth, install MySQL

      Install MySQL service and execute the following command

//（服务名可以不加默认为mysql，一般都使用默认）
mysqld --install [服务名]                     

The result of successful execution should display: Service successfully installed

    After the service is installed, start MySQL by command

net start mysql   //启动
net stop mysql    //停止

Five, modify the default password

mysql -u root -p

                        

Execute the command to modify the code:

ALTER USER 'root'@'localhost' IDENTIFIED BY '新密码';

    After completing the above process, the configuration of MySQL is almost over, then we need to install a visualization tool to clearly know the data in our database.

Six, Navicat download
