MySQL（压缩包）配置过程

1.下载MySQL安装包
MySQL :: Download MySQL Community Server

2.将下载完成的压缩包解压到某一目录，如：

C:\MySQL

并在系统环境中添加以上目录。

 3.在上述目录下新建my.ini文件，并在文件中输入以下内容：

[mysqld]
port=3306
basedir=C:\MySQL
datadir=C:\MySQL\data
max_connections=200
max_connect_errors=10
character-set-server=utf8mb4
default-storage-engine=INNODB
default-storage-engine=INNODB
[mysql]
default-character-set=utf8mb4
[client]
port=3306
default-character-set=utf8mb4

4.使用命令

mysqld --initialize --console

初始化MySQL服务，并记下此处生成的root用户的初始密码：

C:\Windows\System32>mysqld --initialize --console
2024-10-13T12:10:48.416788Z 0 [System] [MY-013169] [Server] C:\MySQL\bin\mysqld.exe (mysqld 8.0.39) initializing of server in progress as process 15240

5.安装并启动MySQL服务：

C:\Windows\System32>mysqld install

C:\Windows\System32>net start mysql

MySQL 服务已经启动成功。

6.使用先前生成的密码登录root用户并使用命令

ALTER USER 'root'@'localhost' IDENTIFIED BY '123456';

修改其密码：
