安装MySQLmysql-5.6.14可以参考32313133353236313431303231363533e59b9ee7ad9431333361306264如下安装步骤：

1、将解压缩后的文件放到自己想要的地方，并配置环境变量。示例中存放的目录为：F:\mysql\mysql-5.6.14-winx64

2、在环境变量中添加：MYSQL_HOME:F:\mysql\mysql-5.6.14-winx64，在path路径中加入：%MYSQL_HOME%\bin。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。

3、修改ini配置文件

5.6.14的解压缩版里有一个my-default.ini文件，copy一份改名为my.ini放在同级目录下。修改my.ini， my.ini内容如下：

# For advice on how to change settings please see

# http://dev.mysql.com/doc/refman/5.6/en/server-configuration-defaults.html

# *** DO NOT EDIT THIS FILE. It's a template which will be copied to the

# *** default location during install, and will be replaced if you

# *** upgrade to a newer version of MySQL.

[mysqld]

loose-default-character-set=utf8

basedir = F:/mysql/mysql-5.6.14-winx64

datadir = F:/mysql/mysql-5.6.14-winx64/data

[client]

loose-default-character-set=utf8

[WinMySQLadmin]

Server=F:/mysql/mysql-5.6.14-winx64/bin/mysqld.exe

# Remove leading # and set to the amount of RAM for the most important data

# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.

# innodb_buffer_pool_size = 128M

# Remove leading # to turn on a very important data integrity option: logging

# changes to the binary log between backups.

# log_bin

# 设置mysql的安装目录

# 设置mysql数据库的数据存放目录

# These are commonly set, remove the # and set as required.

# basedir = .....

# datadir = .....

# port = .....

# server_id = .....

character-set-server=utf8

# Remove leading # to set options mainly useful for reporting servers.

# The server defaults are faster for transactions and fast SELECTs.

# Adjust sizes as needed, experiment to find the optimal values.

# join_buffer_size = 128M

# sort_buffer_size = 2M

# read_rnd_buffer_size = 2M

sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

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:\>f:

F:\>cd F:\mysql\mysql-5.6.14-winx64\bin

F:\mysql\mysql-5.6.14-winx64\bin>mysqld -install

Service successfully installed.

5、启动服务

F:\mysql\mysql-5.6.14-winx64\bin>cd\

F:\>net start mysql

MySQL 服务正在启动 .

MySQL 服务已经启动成功。

6、配置用户

还在上面的命令窗口里面，输入命令：mysql -u root -p

回车后提示输入密码。

mysql解压缩版初次安装管理员root的密码为空，因此直接再回车一次就登入mysql数据库了。

F:\>mysql -u root -p

Enter password:

Welcome to the MySQL monitor. Commands end with ; or \g.

成功后

输入命令：use mysql;　　　　　　/*使用mysql数据库*/

mysql> use mysql

Database changed

输入命令：select host,user,password from user;　　　　/* 查看系统的账户信息 */

mysql> select host,user,password from user;

+-----------+------+----------+

| host | user | password |

+-----------+------+----------+

| localhost | root | |

| 127.0.0.1 | root | |

| ::1 | root | |

| localhost | | |

+-----------+------+----------+

4 rows in set (0.00 sec)

host：代表mysql服务允许哪个IP来的请求。localhost和127.0.0.1指mysql服务所在的主机，即本地。：：1是IPV6的IP地址写法，

全称为：0000:0000:0000:0000:0000:0000:0000:0001。现在都是IPV4的网络，可以不用管他。

user：指账户名称。不同的host下账户名称可以相同。

password：密码。

可以看到，默认账户里只支持本地连接，并且账户没有密码。现在的问题明确了，就是要将匿名用户删除，为root用户添加远程访问和密码，再为自己添加个人账户。指令如下：

mysql> update user set password=PASSWORD('root') where user='root';

Query OK, 3 rows affected (0.00 sec)
