win10安装mysql8

一、下载

从官网（传送门）下载zip文件放在安装位置,我放在D盘根目录了

地址： https://downloads.mysql.com/archives/community/

下载好之后解压，我的位置在 D:\mysql-8.0.34-winx64

二、修改配置

进入解压文件之后创建 my.ini文件 内容如下：

需要修改的位置basedir和datadir

datadir：数据库的数据的存放目录 我在安装目录创建了一个data，有其他需求的自己改

[mysqld]
# 设置3306端口
port=3306
# 设置mysql的安装目录
basedir=D:\mysql-8.0.34-winx64 
# 设置mysql数据库的数据的存放目录
datadir=D:\mysql-8.0.34-winx64\data 
# 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

三、安装

以管理员身份运行cmd

然后进入mysql安装目录下的bin文件夹（D:\mysql-8.0.34-winx64\bin）

1、输入：mysqld --initialize --console 命令初始化mysql

如果配置环境变量就没必要进入到bin目录了

C:\WINDOWS\system32>D:
D:\>cd D:\mysql-8.0.34-winx64\bin
D:\mysql-8.0.34-winx64\bin>mysqld --initialize --console
2023-10-24T02:24:46.512711Z 0 [Warning] [MY-010918] [Server] 'default_authentication_plugin' is deprecated and will be removed in a future release. Please use authentication_policy instead.
2023-10-24T02:24:46.512743Z 0 [System] [MY-013169] [Server] D:\mysql-8.0.34-winx64\bin\mysqld.exe (mysqld 8.0.34) initializing of server in progress as process 9292

2023-10-24T02:24:46.659221Z 1 [System] [MY-013576] [InnoDB] InnoDB initialization has started.

2023-10-24T02:25:02.299377Z 6 [Warning] [MY-013360] [Server] Plugin mysql_native_password reported: ''mysql_native_password' is deprecated and will be removed in a future release. Please use caching_sha2_password instead'
D:\mysql-8.0.34-winx64\bin>

执行完 mysqld --initialize --console 命令后稍等一会 就会出现一个临时密码 Qpf&Hqo2AwuY(备份一下，一会修改密码需要用的一下)

[Note] [MY-010454] [Server] A temporary password is generated for root@localhost: Qpf&Hqo2AwuY

2、安装mysql服务

输入：mysqld  --install   命令

D:\mysql-8.0.34-winx64\bin>mysqld --install
Service successfully installed.

3、启动MySQL服务

输入：net start mysql   命令

D:\mysql-8.0.34-winx64\bin>net start mysql
MySQL 服务正在启动 ...
MySQL 服务已经启动成功。

4、进入mysql

输入：mysql -u root -p 命令，然后在输入刚刚生成的临时密码

D:\mysql-8.0.34-winx64\bin>mysql -u root -p
Enter password: ************

5、修改密码

输入：ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '123456';

mysql> ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '123456';
Query OK, 0 rows affected (0.15 sec)
mysql>

到这安装就结束了

记得配置一下环境变量！
