1：安装msyql5.6介质（mysql-5.6.24-winx64.msi）以后没有myslq服务：
解决：
管理员身份cmd进入bin目录：
mysqld.exe -install
Service successfully installed
启动服务即可
2：修改mysql root用户没有密码问题：
解决：
mysql -u root -p 直接回车，无需输入密码就可以进入数据库了。 此时在命令行下执行 use mysql （切换到系统数据库）
执行：update user set password=PASSWORD("root") where user='root';重启mysql服务即可
3：修改mysql字符编码：
解决：
将mysql的安装目录（C:Program FilesMySQLMySQL Server 5.6）的my-default.ini复制一份，重命名为my.ini（因为mysql5.6没有my.ini文件）
添加:
[mysql]
port=3306
default-character-set=utf8
[mysqld]
character-set-server=utf8
重启服务即可：
mysql> show variables like '%character%';
+--------------------------+---------------------------------------------------------+
| Variable_name | Value |
+--------------------------+---------------------------------------------------------+
| character_set_client | utf8 |
| character_set_connection | utf8 |
| character_set_database | utf8 |
| character_set_filesystem | binary |
| character_set_results | utf8 |
| character_set_server | utf8 |
| character_set_system | utf8 |
