1、从官网下载MySQL5.7.21解压版64位
2、解压（我的解压路径为：H:\mysql-5.7.21-winx64，我将其改名去掉-，并移动到此位置H:\develop\mysql5.7.21。
3、添加环境变量（系统变量）：
变量名：MYSQL_HOME
变量值：H:\develop\mysql5.7.21
修改系统变量path，在path原有值后添加路径：%MYSQL_HOME%\bin。
以管理员身份运行命令行工具：
H:\>mysqld --version
mysqld Ver 5.7.21 for Win64 on x86_64 (MySQL Community Server (GPL))
4、在H:\develop\mysql5.7.21路径下新建配置文件：my.ini，在my.ini中保存以下内容：
[mysqld]

#### replication configure
server-id = 1
replicate-wild-ignore-table = mysql.%
replicate-wild-ignore-table = information_schema.%
replicate-wild-ignore-table = performance_schema.%
replicate-wild-ignore-table = sys.%
binlog-format=ROW
binlog-row-image=full

enforce-gtid-consistency=true
#### time configure

# [client]
#socket=H:\develop\mysql5.7.21\mysqllog\mysql.sock
5、命令行运行
H:\>mysqld --initialize --basedir=H:\develop\mysql5.7.21 --datadir=H:\develop\mysql5.7.21\data
H:\>mysqld --install
Service successfully installed.
H:\>net start mysql
MySQL 服务正在启动 .
MySQL 服务已经启动成功。
6、在H:\develop\mysql5.7.21\mysqllog\mysql01.err 日志中找到

初始密码
7、登录mysql
