MySQL8.0 下载安装启动(Windows10)

下载

下载地址：https://dev.mysql.com/downloads/mysql/8.0.html

现在的版本是：MySQL Community Server 8.0.16

解压

解压到安装目录，比如F盘根目录，F:\mysql-8.0.16-winx64

创建my.ini

my.ini是MySQL安装的配置文件

[mysql]

# 设置mysql客户端默认字符集

default-character-set=utf8mb4

[mysqld]

# 设置3306端口

port=3306

# 设置mysql的安装目录

basedir=D:\\develop\\software\\mysql-8.0.13-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=D:\\develop\\software\\mysql-8.0.13-winx64\\data

# 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=utf8mb4

# 创建新表时将使用的默认存储引擎

default-storage-engine=INNODB

初始化

以管理员权限打开cmd，在F:\mysql-8.0.16-winx64\bin目录下执行：

mysqld --defaults-file=F:\mysql-8.0.16-winx64\my.ini --initialize --console

控制台有输出如下，说明安装成功：

F:\mysql-8.0.16-winx64\bin>mysqld --defaults-file=F:\mysql-8.0.16-winx64\my.ini --initialize --console

2019-06-13T13:05:12.739945Z 0 [System] [MY-013169] [Server] F:\mysql-8.0.16-winx64\bin\mysqld.exe (mysqld 8.0.16) initializing of server in progress as process 16556

这里root@localhost: 8WEM&pMQk#xR中8WEM&pMQk#xR就是数据库的初始密码。稍后需要更改。

启动、关闭

启动MySQL server，只需要执行mysqld即可，mysqld --console可以在控制台输出日志。

F:\mysql-8.0.16-winx64\bin>mysqld --console

2019-06-14T11:20:12.875518Z 0 [System] [MY-010116] [Server] F:\mysql-8.0.16-winx64\bin\mysqld.exe (mysqld 8.0.16) starting as process 13788

在命令行中只需“CRTL + C”就可以关闭数据库，也可以使用mysqladmin -u root shutdown。

F:\mysql-8.0.16-winx64\bin>mysql -uroot -p

修改密码

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '你的密码';

注意：mysql8新的密码策略，很多mysql客户端工具不支持，所以用原来的密码策略。
