因为最近换了电脑，正好趁这个机会记录下，myql安装的相关配置。
环境版本说明
- mysql-8.0.15-winx64
- windows10 x64
1、增加环境变量配置
增加mysql环境变量配置：
新增MYSQL_HOME
PATH后追加：%MYSQL_HOME%\bin
2、新增my.ini文件
在mysql解压根目录增加文件my.ini,添加以下内容(里面对应的【安装目录】，【存放目录】需要根据自己实际路径进行修改)。
版本8以上，目录自带data文件夹，不需要再重新新建。
[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=D:\00_develop\mysql-8.0.13
; 设置mysql数据库的数据的存放目录
datadir=D:\00_develop\mysql-8.0.13\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
3、执行相关命令：
1、mysqld --initialize --console，此时会显示出mysql初始密码，需要记录以便后面修改密码使用

2、net start mysql
这一步如果没有install如果报错 无效的服务名，
执行：mysqld --install 成功之后继续按照这个步骤执行
3、mysql -u root -p
4、然后输入上面第一步返回的初始密码
5、ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'mysql';（修改root用户的密码为mysql）
直接上运行命令
PS C:\Users\Administrator> d:
PS D:\> cd D:\00_develop\mysql-8.0.13\bin
PS D:\00_develop\mysql-8.0.13\bin> mysqld --initialize --console
