1.在环境变量中添加：MYSQL_HOME:C: 5_studymysql-5.7.10-winx64，在path路径中加入：%MYSQL_HOME%in。配置环境变量不是必须的，只是为了能更方便的在命令行中使用mysql的命令行工具。
2.修改my.ini配置文件
将my-default.ini拷贝一份，重命名为my.ini 内容要包含如下部分：
[mysqld]
loose-default-character-set=utf8
basedir="C:/05_study/mysql-5.7.10-winx64"
datadir="C:/05_study/mysql-5.7.10-winx64/data"
[client]
loose-default-character-set=utf8
[WinMySQLadmin]
Server=C:/05_study/mysql-5.7.10-winx64/bin/mysqld.exe
character-set-server=utf8
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
3.注意，不要自已手动去建C:/05_study/mysql-5.7.10-winx64/data文件夹。
4.安装服务
开始——所有程序——附件——命令提示符，右键以管理员身份运行。 输入命令：
C: 5_studymysql-5.7.10-winx64in>mysqld --initialize-insecure --user=mysql
C: 5_studymysql-5.7.10-winx64in>
C: 5_studymysql-5.7.10-winx64in>mysqld -install
Service successfully installed.
C: 5_studymysql-5.7.10-winx64in>net start mysql
The MySQL service is starting.
The MySQL service was started successfully.
C: 5_studymysql-5.7.10-winx64in>
在命令行启动mysql命令为： net start mysql 关闭mysql命令为：net stop mysql
如果要重装，先停掉mysql，再mysqld -remove 就可以卸载掉.
5.登录mysql，修改root用户密码为什123456
C: 5_studymysql-5.7.10-winx64in>mysql -u root

6.远程登录配置
允许root用户在任何地方进行远程登录，并具有所有库任何操作权限，具体操作如下：
1）在本机先使用root用户登录mysql：
命令行执行：mysql -u root -p
输入密码（第7步中设置的密码）：123456
2）进行授权操作：
mysql>GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'youpassword' WITH GRANT OPTION;
重载授权表：
mysql>FLUSH PRIVILEGES;
退出mysql：quit
