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-winx64in目录下执行：
mysqld --defaults-file=F:mysql-8.0.16-winx64my.ini --initialize --console
控制台有输出如下，说明安装成功：
F:mysql-8.0.16-winx64in>mysqld --defaults-file=F:mysql-8.0.16-winx64my.ini --initialize --console

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-winx64in>mysqld --console

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。
登录
使用mysql -uroot -p登录，输入上面的那个密码8WEM&pMQk#xR即可
F:mysql-8.0.16-winx64in>mysql -uroot -p
Enter password: ************

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。
