  在select operating system中选择Microsoft Windows,下方对应出现最新版本的MySQL,目前是MySQL 8.0.20,有两个zip文件,选择第一个Windows (x86, 64-bit), ZIP Archive点击右侧的Download按钮进行下载
 
  官网下载有时速度比较慢,直接点击链接也可以下载:mysql 8.0.20
 
  安装与配置
 
  将下载好的压缩包解压缩到全英文目录下,比如我在D盘新建了MySQL文件夹,解压到该文件夹下,D:/MySQL

  然后把mysql 8.0.20所在的路径D:/MySQL/mysql-8.0.20-winx64添加到环境变量Path中

  接下来正式安装和配置MySQL:
 
  (一)首先在D:/MySQL/mysql-8.0.20-winx64路径下创建一个my.ini文件,直接新建文本文档,然后重命名为my.ini即可。

  在文档中添加以下内容:
  (注意修改basedir和datadir的路径)
 
  [mysqld]
  # 设置3306端口
  port=3306
  # 设置mysql的安装目录
  basedir=D://MySQL//mysql-8.0.20-winx64 # 此处为mysql的解压缩路径
  # 设置mysql数据库的数据的存放目录
  datadir=D://MySQL//mysql-8.0.20-winx64//Data # 此处同上,先不要在路径中创建Data目录,后面初始化时会自动生成
  # 允许最大连接数
  max_connections=200
  # 允许连接失败的次数。这是为了防止有人从该主机试图攻击数据库系统
  max_connect_errors=10
  # 服务端使用的字符集默认为UTF8
  character-set-server=utf8
  # 创建新表时将使用的默认存储引擎
  default-storage-engine=INNODB
  # 默认使用“mysql_native_password”插件认证
  default_authentication_plugin=mysql_native_password
  [mysql]
  # 设置mysql客户端默认字符集
  default-character-set=utf8
  [client]
  # 设置mysql客户端连接服务端时默认使用的端口
  port=3306
  default-character-set=utf8
  (二)以管理员权限打开cmd(注意要以管理员权限打开),并将路径切换到D:/MySQL/mysql-8.0.20-winx64/bin
 
  Microsoft Windows [Version 10.0.18363.815]
  (c) 2019 Microsoft Corporation。保留所有权利。
 
  C:/Windows/system32>D:
 
  D:/>cd MySQL
 
  D:/MySQL>cd mysql-8.0.20-winx64
 
  D:/MySQL/mysql-8.0.20-winx64>cd bin
 
  D:/MySQL/mysql-8.0.20-winx64/bin>
  输入mysqld --initialize --console,进行初始化。该步可以得到mysql的初始密码,root@localhost后面那一串就是初始密码,先记录下来,待会要用到
 
  D:/MySQL/mysql-8.0.20-winx64/bin>mysqld --initialize --console
  2020-05-10T11:26:21.895908Z 0 [System] [MY-013169] [Server] D:/MySQL/mysql-8.0.20-winx64/bin/mysqld.exe (mysqld 8.0.20) initializing of server in progress as process 9764
  2020-05-10T11:26:21.897278Z 0 [Warning] [MY-013242] [Server] --character-set-server: 'utf8' is currently an alias for the character set UTF8MB3, but will be an alias for UTF8MB4 in a future release.
  Please consider using UTF8MB4 in order to be unambiguous.
  2020-05-10T11:26:21.915225Z 1 [System] [MY-013576] [InnoDB] InnoDB initialization has started.
  2020-05-10T11:26:22.619057Z 1 [System] [MY-013577] [InnoDB] InnoDB initialization has ended.

  输入mysqld --install(如果需要安装多个mysql服务,这步输入mysqld --install [服务名])
 
  D:/MySQL/mysql-8.0.20-winx64/bin>mysqld --install
  Service successfully installed.
  显示Service successfully installed则说明安装成功
  输入net start mysql,启动MySQL服务
 
  D:/MySQL/mysql-8.0.20-winx64/bin>net start mysql
  The MySQL service is starting.
  The MySQL service was started successfully.
  输入mysql -u root -p,使用初始密码登录mysql,在Enter password后输入初始密码
 
  D:/MySQL/mysql-8.0.20-winx64/bin>mysql -u root -p
  Enter password: ************
  Welcome to the MySQL monitor. Commands end with ; or /g.
  Your MySQL connection id is 8
  Server version: 8.0.20

  Type 'help;' or '/h' for help. Type '/c' to clear the current input statement.
  登录后,把初始密码修改掉,可以设置成自己容易记住的密码。
  输入ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '自己定义的密码'; (分号一定要带)
 
  mysql> ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '自己定义的密码;
  Query OK, 0 rows affected (0.02 sec)
  到这一步就完成了
  输入show database; ,可以查看包含哪些数据表
 
  mysql> show databases;
  +--------------------+
  | Database |
  +--------------------+
  | information_schema |
  | mysql |
  | performance_schema |
  | sys |
  +--------------------+
  4 rows in set (0.01 sec)
