下载
去MySQL官网下载：https://dev.mysql.com/downloads/mysql/5.6.html#downloads
我下载的是5.6.38 windows 64位版本，或者访问下面地址，并选择相应版本下载。

安装服务
1.解压MySQL压缩包说明：这里说的指定位置一般是开发者计算机上固定存放软件的路径。注意：这个路径不要带中文、特殊字符和空格。例如，我把解压以后的文件和文件夹存放在了
E:softwaremysql-5.6.38-winx64
2.修改配置文件，这里网上很多资料说需要新建个my.ini，然后配置。其实在本来的my-default.ini上进行修改就可以。
配置项：
[mysqld]
basedir=E:softwaremysql-5.6.38-winx64
datadir=E:softwaremysql-5.6.38-winx64data
max_connections=4000
innodb_lock_wait_timeout=500
character-set-server=utf8
port = 3306
#创建新表时将使用的默认存储引擎
default-storage-engine=INNODB
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
3.添加环境变量（非必须）
将以下目录添加到环境变量 path 中：
E:softwaremysql-5.6.38-winx64in
4.通过命令安装MySQL服务
1.必须已管理员身份运行： cmd
2.进入目录： C:UsersAdministrator>e:
3.到指定目录下：cd E:softwaremysql-5.6.38-winx64in
4.安装服务：mysqld -install
5.启动服务：net start mysql
cmd 执行命令：
Microsoft Windows [版本 10.0.16299.1087]
(c) 2017 Microsoft Corporation。保留所有权利。
C:UsersAdministrator>e:
E:>cd E:softwaremysql-5.6.38-winx64in
E:softwaremysql-5.6.38-winx64in>mysqld -install
Service successfully installed.
E:softwaremysql-5.6.38-winx64in>net start mysql
MySQL 服务正在启动 ..
MySQL 服务已经启动成功。
E:softwaremysql-5.6.38-winx64in>
5. 修改root账号的密码
刚安装完成时root账号默认密码为空，此时可以将密码修改为指定的密码。如：123456
c:>mysql –uroot
mysql>show databases;
mysql>use mysql;
mysql>UPDATE user SET password=PASSWORD("123789") WHERE user='root';
mysql>FLUSH PRIVILEGES;
mysql>QUIT
cmd 执行命令：
E:softwaremysql-5.6.38-winx64in>mysql -uroot
