------Windows下安装MySQL：使用管理员权限，已在windows?10、Windows7、XP上测试通过，XP不支持5.7及其以上版本

---?5.5、5.6、5.7、8.0?默认密码都为空，8.0数据库需要8.0的客户端才能无密码登录

mysql?-uroot?-p?-P3308

--5.5、5.6、5.7修改密码和允许远程登陆

update mysql.user set authentication_string=password("lhr")?where user="root";

update mysql.user set Host="%" where Host="127.0.0.1";

update mysql.user set Host="%" where Host="localhost";

set password=password('lhr');

grant all privileges on *.*?to root@'%' identified?by 'lhr';

flush?privileges;

--8.0修改密码和允许远程登陆

update mysql.user set Host="%" where Host="localhost";

update mysql.user set authentication_string='' where user='root';

ALTER USER 'root'@'%' IDENTIFIED?WITH mysql_native_password?BY 'lhr';?--?多执行几次

flush?privileges;

select user,host?from mysql.user;

--mysql?8.0远程连接，在参数文件的[mysqld]下添加：

default_authentication_plugin=mysql_native_password

--mysql?8.0.15忘记密码，修改密码:http://blog.itpub.net/26736162/viewspace-2650907/

1、停止服务

2、管理员权限执行：D:\Program_Files\MySQL\mysql-8.0.15-winx64\bin\mysqld?--defaults-file="D:\Program_Files\MySQL\mysql-8.0.15-winx64\mysql803314.ini"?--console?--skip-grant-tables?--shared-memory

3、mysql?-uroot?-p?-P3308?#无密码登录

update mysql.user set authentication_string='' where user='root';

4、退出，关闭第2步的console，重新空密码登录

5、修改密码：ALTER USER 'root'@'%' IDENTIFIED?WITH mysql_native_password?BY 'lhr';

----同版本安装多实例

1、拷贝源库的data文件夹为data3307，删除里边的业务数据库，对于5.6版本需要保留默认数据库mysql、performance_schema、test，对于5.7和8.0版本需要所有数据库都删除

2、拷贝源库的my.ini文件到data3307目录下命名my3307.ini，并修改相关参数：basedir、datadir、port等

2、初始化：

D:\Program_Files\MySQL\mysql-8.0.15-winx64\bin\mysqld?--initialize-insecure?--user=mysql?--basedir=D:\Program_Files\MySQL\mysql-8.0.15-winx64?--datadir=D:\Program_Files\MySQL\mysql-8.0.15-winx64\data3307

3、安装服务：

D:\Program_Files\MySQL\mysql-8.0.15-winx64\bin\mysqld?install?mysql563307?--defaults-file="D:\Program_Files\MySQL\mysql-8.0.15-winx64\data3307\my3307.ini"

注意：

?????1、可以不拷贝源软件为新的文件夹。当然也可以拷贝一份全新的环境。

?????2、每个实例的配置文件必须是单独的。

首先切换到MySQL的bin目录下，执行如下命令：

mysqld?remove

mysqld?install

------Windows下卸载MySQL

①　关闭MySQL相关进程后并停止MySQL服务（services.msc）

②　命令行执行：sc?delete mysql或mysqld?remove

③　删除所有MySQL文件

④　regedit打开注册表，删除以下位置的3个文件夹：

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\Eventlog\Application\MySQL

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Services\Eventlog\Application\MySQL
