解压MySQL压缩包
将以下载的MySQL压缩包解压到自定义目录下,我的解压目录是:
"D:\Program Files\MySQL\mysql-5.6.13-win32"
添加环境变量
操作如下：
1）右键单击我的电脑-属性-高级系统设置(高级)-环境变量
点击系统变量下的新建按钮
输入变量名：MYSQL_HOME
输入变量值：D:\Program Files\mysql-5.6.11-winx64
#即为mysql的自定义解压目录。
2）选择系统变量中的Path
点击编辑按钮
在变量值中添加变量值：%MYSQL_HOME%\bin
注意是在原有变量值后面加上这个变量，用;隔开，不能删除原来的变量值，
1.
下载MySQL压缩包 下载地址:MySQL :: Download MySQL Community Server (Archived Versions) 此处下载的是MySQL的5.7.31版本,windows,64位。 下载得到的zip压缩包:
2.
安装mysql mysql-5.3.71-winx64.zip是免安装的版本。 解压zip文件 将解压后的压缩包文件放入路径(不要有中文路径)(这里我放在了D:Program Files下)
3.
创建配置文件 在mysql安装目录下,创建一个my.ini配置文件,
安装MySQLmysql-5.6.14可以参考如下安装步骤：
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
#
# *** 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\binmysqld -install
Service successfully installed.
5、启动服务
F:\mysql\mysql-5.6.14-winx64\bincd\
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:

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)
