安装mysql-8.0.15-winx64.zip

1.首先卸载其他版本（如果有的话）

2.下载mysql：https://dev.mysql.com/downloads/file/?id=484900

3.下载后，解压。在文件夹下新建my.ini文件

内容：

[mysql]

# 设置mysql客户端默认字符集

default-character-set=utf8

[mysqld]

# 设置3306端口

port = 3306

# 设置mysql的安装目录

basedir=E:\mysql-8.0.15-winx64

# 设置 mysql数据库的数据的存放目录，MySQL 8+ 不需要以下配置，系统自己生成即可，否则有可能报错

# datadir=C:\web\sqldata

# 允许最大连接数

max_connections=20

# 服务端使用的字符集默认为8比特编码的latin1字符集

character-set-server=utf8

# 创建新表时将使用的默认存储引擎

default-storage-engine=INNODB

4.cmd进入文件夹的bin目录

5.运行mysqld --initialize --console 会生成一个初始密码，登录后需要改掉密码，启动，

如果mysqld install 遇到《Install/Remove of the Service Denied》错误，请以管理员身份运行cmd

6.登录进去后，用初始密码进行操作会报错

ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement.

只需要修改密码，记得加分号

alter user 'root'@'localhost' identified by '1234'；

7.退出去后，用初始密码就登录不进来了，密码修改成功

8.mysql8版本连接Navicat的时候可能会报错，因为由于跟5.0的加密规则不一样，连接会报错2059，

只需要在mysql中修改一下（root:账户，localhost：地址，‘1234’：root的密码）

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '1234';
