1.首先下载mysql安装包
https://dev.mysql.com/downloads/mysql/
这个版本不要听网上说的新建data文件夹和my.ini 或 my-default.ini 按我说的 本人亲测
配置环境变量在Path下添加 D:\mysql-8.0.19-winx64\bin
以管理员身份运行,在命令行输入cd+mySQL的bin目录的安装路径
C:\Windows\system32>cd C:\Program Files\MySQL\MySQL Server5.6\bin
2. MySQL的初始化及服务安装
2.1 按“win”键打开开始菜单,在搜索框中输入“cmd”,在搜索结果中选中“命令提示符”程序,右键选择“以管理员身份运行”
2.2 初始化
用管理员权限打开CMD或者Windows Powershell
使用命令:mysqld --initialize --console
使用CMD命令操作后如下:
C:\Windows\system32>D:\Python\mysql-8.0.12-winx64\bin\mysqld --initialize --console
2018-09-13T14:36:55.758742Z 0 [System] [MY-013169] [Server] D:\Python\mysql-8.0.12-winx64\bin\mysqld (mysqld 8.0.12) initializing of server in progress as process 3104
2018-09-13T14:37:12.072904Z 5 [Note] [MY-010454] [Server] A temporary *password is generated for root@localhost: `Gaz7FGbaTwe
2018-09-13T14:37:23.274980Z 0 [System] [MY-013170] [Server] D:\Python\mysql-8.0.12-winx64\bin\mysqld (mysqld 8.0.12) initializing of server has completed
记录下密码,这里的密码是Gaz7FGbaTw*e,密码是随机生成的每个人都不一样,此处生成的密码在后面修改密码时要用。
2.3 安装mysql服务
使用命令: mysqld --install
C:\Windows\system32>D:\Python\mysql-8.0.12-winx64\bin\mysqld --install
Service successfully installed.
2.4 启用服务
使用命令: net start mysql
C:\Windows\system32>D:\Python\mysql-8.0.12-winx64\bin>net start mysql
MySQL 服务正在启动 ..
MySQL 服务已经启动成功。
2.5 修改密码
输入命令登陆: mysql -u root -p
输入刚才保存的密码,如 Gaz7FGbaTw*e
使用命令: ALTER USER ‘root'@‘localhost' IDENTIFIED WITH mysql_native_password BY ‘新密码';
注意密码一定要6位数以上
比如我设置的密码是123456
D:\Python\mysql-8.0.12-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: 8.0.12
mysql> ALTER user 'root'@'localhost' IDENTIFIED BY '123456'
-> ;
Query OK, 0 rows affected (1.98 sec)
2.6 使用新密码登陆
使用命令:mysql -u root -p
D:\Python\mysql-8.0.12-winx64\bin>mysql -u root -p
Enter password: ******
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 10

总结问题:2.4 执行 net start mysql 命令启动服务时 一直出错 启动不了
我的错误是开始进入的文件夹位置不对,所以需要去除服务从新进入对的文件夹下载安装启动
以管理员身份运行,在命令行输入cd+mySQL的bin目录的安装路径
C:\Windows\system32>cd C:\Program Files\MySQL\mysql-8.0.19-winx64\bin
C:\Program Files\MySQL\mysql-8.0.19-winx64\bin>mysqld --remove
Service successfully removed.
C:\Program Files\MySQL\mysql-8.0.19-winx64\bin>mysqld --install
Service successfully installed.
C:\Program Files\MySQL\mysql-8.0.19-winx64\bin>net start mysql
MySQL 服务正在启动 .
MySQL 服务已经启动成功。
