1.下载及压解缩过程不做详细说明。
2.在安装目录下(我的安装目录是在d:\Program Files\mysql) 添加 my.ini 文件，如下是内容
[mysqld]
# 设置3306端口
port=3306
# 设置mysql的安装目录，自行确定
basedir=d:\Program Files\mysql
# 设置mysql数据库的数据的存放目录，自行确定
datadir=d:\mysql\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
3.配置环境变量，若不配置则需要进入解压缩的路径去执行（如下）
D:\Program Files\mysql\bin>mysqld --initialize --console
2018-05-29T06:41:26.291500Z 0 [System] [MY-013169] [Server] D:\Program Files\mys
ql\bin\mysqld.exe (mysqld 8.0.11) initializing of server in progress as process
12196
2018-05-29T06:41:31.572802Z 5 [Note] [MY-010454] [Server] A temporary password i
s generated for root@localhost: Xg0pLBMP&x#M #这里是系统产生的root初始密码，后续登录时要用
2018-05-29T06:41:37.036115Z 0 [System] [MY-013170] [Server] D:\Program Files\mys
ql\bin\mysqld.exe (mysqld 8.0.11) initializing of server has completed
4.注册mysql服务
D:\Program Files\mysql\bin>mysqld install mysql
Service successfully installed.
启动服务
D:\Program Files\mysql\bin>net start mysql
mysql 服务正在启动 .
mysql 服务已经启动成功。
5.登录并修改密码
D:\Program Files\mysql\bin>mysql -u root -p
Enter password: ************
