首先将下载完成zip包解压到某个目录，如：E:\mysql-5.7.16-winx64
修改环境变量path增加E:\mysql-5.7.16-winx64\bin
在E:\mysql-5.7.16-winx64目录中新建目录data,将默认的my-default.ini复制为my.ini,同时配置以上字段：
basedir = E:\mysql-5.7.16-winx64datadir = E:\mysql-5.7.16-winx64\dataport = 3306server_id = 1
将最后一行注释,如果不注释也不影响，安装时会 有一些报错信息，但不影响使用
#sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
安装MySQL服务，注意一定要在mysql的bin目录下安装
E:\mysql-5.7.16-winx64\bin>mysqld --install MySQL
如果不是，可能在启动服务时出现如下错误：
发生系统错误 2。系统找不到指定的文件。
此时需要移除mysql服务重新安装
mysqld --remove MySQLService successfully removed.
初始化MySQL,以管理员身份运行cmd,进入到mysql的bin目录运行
mysqld --initialize --explicit_defaults_for_timestamp --console
mysql-5.7.16-winx64\bin>mysqld --initialize --explicit_defaults_for_timestamp --console2016-10-15T04:38:46.341663Z 0 [Warning] InnoDB: New log files created, LSN=457902016-10-15T04:38:46.908164Z 0 [Warning] InnoDB: Creating foreign key constraint system tables.2016-10-15T04:38:47.161759Z 0 [Warning] Gtid table is not ready to be used. Table 'mysql.gtid_executed' cannot be opened.2016-10-15T04:38:47.182800Z 1 [Note] A temporary password is generated for root@localhost: K9Otza#ftMss
注意看最后一行 的密码输出
A temporary password is generated for root@localhost: K9Otza#ftMss
如果想重新初始化，需要清空data目录下的数据，否则会出现如下报错：
mysqld --initialize --explicit_defaults_for_timestamp --console2016-10-16T02:15:50.321689Z 0 [Warning] 'NO_ZERO_DATE', 'NO_ZERO_IN_DATE' and 'ERROR_FOR_DIVISION_BY_ZERO' sql modes should be used with strict mode.
