1、Windows下安装mysql-8.0.12及修改初始密码

1. 解压压缩包,放置到任意目录

注意目录最好是英文

这是我的目录:
D:\Python\mysql-8.0.12-winx64\

2. 初始化

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: 4P!w2fqBruGi
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,后面修改密码还要用</br>
在这里:

[Server] A temporary password is generated for root@localhost: 4P!w2fqBruGi

最后面的 ==4P!w2fqBruGi== 就是密码,密码是随机生成的每个人都不一样

3. 安装

使用命令: mysqld –install

C:\Windows\system32>D:\Python\mysql-8.0.12-winx64\bin\mysqld --install
Service successfully installed.

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。

5. 修改密码

  1. 输入命令登陆: mysql -u root -p </br>
  2. 输入刚才保存的密码
  3. 使用命令: ALTER USER ‘root’@’localhost’ IDENTIFIED WITH mysql_native_password BY ‘新密码’;</br>
  4. 注意密码一定要6位数以上
  5. 我设置的密码是111111 ,告诉你们没关系
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 '111111'
    -> ;
Query OK, 0 rows affected (1.98 sec)

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
Server version: 8.0.12 MySQL Community Server - GPL

7.配置环境变量:

  1. 进入 计算机–高级系统设置–高级–环境变量
  2. 然后新建系统变量
  3. 变量值改为自己mysql解压的路径
  4. 变量名:MYSQL_HOME
  5. 变量值:D:\Python\mysql-8.0.12-winx64\
  6. path里添加:%MYSQL_HOME%\bin;(分号不要忘记)
  7. 重新打开CMD或者Windows Powershell,之直接输入mysql登陆
