mysql压缩包安装配置

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

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：

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;
