1.官网下载zip包
2.放到本地某个盘中
解压到当前目录下
3.windows 中大部分没有 data 目录和 my-default.ini
自己建立一个my.ini
4.将下面的代码拷入自己建一个my.ini文件
[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\mysql-8.0.15-winx64
datadir=E:\mysql\mysql-8.0.15-winx64\data
#允许最大连接数
max_connections=200
#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
#
default_authentication_plugin=mysql_native_password
- data 目录会自动生成
5.在bin目录下输入命令
E:\mysql\mysql-8.0.15-winx64\bin>mysqld install
Service successfully installed.
E:\mysql\mysql-8.0.15-winx64\bin>mysqld --initialize
E:\mysql\mysql-8.0.15-winx64\bin>
E:\mysql\mysql-8.0.15-winx64\bin>net start mysql
MySQL 服务正在启动 ....
MySQL 服务已经启动成功。
E:\mysql\mysql-8.0.15-winx64\bin>- 如果发现data 目录出现了就说明安装成功了
6.用net start mysql 启动服务
7.重点
- 需要用管理员模式打开命令行cmd
8.登录 第一次无密码登录
- 8.0之前可以在my.ini 中设置 skip-grant-table
- 8.0之后 命令行输入 mysqld --console --skip-grant-tables --shared-memor
E:\mysql\mysql-8.0.15-winx64\bin>net start mysql
MySQL 服务正在启动 ...
MySQL 服务已经启动成功。
E:\mysql\mysql-8.0.15-winx64\bin>mysqld --console --skip-grant-tables --shared-memory

mysql>获取密码还有一种方式：
- 将E:\mysql\mysql-8.0.15-winx64\data中的内容都删掉然后 mysqld --initialize --console 初始化一下
- 也可以在一开始 调用 mysqld --initialize 的时候就加上 --console
E:\mysql\mysql-8.0.15-winx64\bin>net stop mysql
MySQL 服务正在停止.
MySQL 服务已成功停止。
