win7 64位下如何安装配置mysql-5.7.17-winx64

本人综合了两篇文章得以安装成功：

1. win7 64位下如何安装配置mysql-5.7.4-m14-winx64
2. the MySQL service on local computer started and then stopped

同时在运行“mysqld --initialize”后，提示错误：

2017-01-06T02:12:51.897566Z 0 [Warning] 'NO_ZERO_DATE', 'NO_ZERO_IN_DATE' and 'ERROR_FOR_DIVISION_BY_ZERO' sql modes should be used with strict mode. They will be merged with strict mode in a future release.

因此加入上述配置，最后的配置文件my.ini内容请看文章最后。

终于成功启动mysql，却发现“mysql -uroot” 无法连接数据库，报告无法登录。参考mysql how to fix Access denied for user 'root'@'localhost'，采取如下步骤：

1. 停止mysql服务
2. 以管理员权限打开命令行，把当前目录指向E:\docs\DB\mysql-5.7.17-winx64\bin
3. 运行

   $ mysqld --skip-grant-tables

   
   
4. 再另外打开命令行，运行

   $ mysql -u root mysql
   $mysql> update user set authentication_string=password('my_password') where user='root';
   $mysql> FLUSH PRIVILEGES;

   
   
5. 退出mysql，重新启动

但是再用HeidiSQL 7.0.0.4053 32 Bit连接数据库，提示密码过期。参考 Mysql password expired. Can't connect，在命令行连接mysql后，运行

SET PASSWORD = PASSWORD('new password');

MySQL server终于正常了。

随后把HeidiSQL 升级到9.4.0.5125，使用正常。

最后的配置文件my.ini内容如下：
