1. 下载MySQL Community Server 5.7.17,注意选择系统类型(32位/64位)



2. 解压缩MySQL压缩包到指定目录:



3.添加环境变量
右键-->我的电脑-->属性--> 高级系统设置-->环境变量
新建系统变量:
变量名:MYSQL_HOME
变量值:D:\database\mysql-5.7.17-winx64

再在path末尾中添加 %MYSQL_HOME%\bin
例如:
D:\Python27;C:\Users\duansf\Desktop\vim\vim80;%MYSQL_HOME%\bin

4.注册为windows系统服务:
需要在命令提示符(管理员模式)下执行:

d:\database\mysql-5.7.17-winx64\bin>d:\database\mysql-5.7.17-winx64\bin\mysqld install MySQL --defaults-file="d:\database\mysql-5.7.17-winx64\my.ini"
Service successfully installed.


my.ini内容如下:
[mysql]
# 设置mysql客户端默认字符集
default-character-set=utf8
[mysqld]
#设置3306端口
port = 3306
# 设置mysql的安装目录
basedir=D:/database/mysql-5.7.17-winx64
# 设置mysql数据库的数据的存放目录
datadir=D:/database/mysql-5.7.17-winx64/data
slow_query_log=TRUE
slow_query_log_file=d:/slow_query_log.txt
long_query_time=1
# 允许最大连接数
max_connections=200
# 服务端使用的字符集默认为8比特编码的latin1字符集
character-set-server=utf8
# 创建新表时将使用的默认存储引擎
default-storage-engine=INNODB
# 主从复制参数配置
log_bin = mysql-bin
server_id = 1


5.手动启动MySQL服务:
d:\database\mysql-5.7.17-winx64\bin>net start mysql
MySQL 服务正在启动 ..
MySQL 服务无法启动。

服务没有报告任何错误。


请键入 NET HELPMSG 3534 以获得更多的帮助。




手动启动服务失败，经查看官方资料，解决思路如下：
启动前我们需要使用-initialize初始化Data目录生成并生成随机密码，使用-initialize-insecure可以生成空密码。默认帐号root

此处我们用-initialize-insecure生成空密码


d:\database\mysql-5.7.17-winx64\bin>mysqld --initialize-insecure

d:\database\mysql-5.7.17-winx64\bin>net start mysql
MySQL 服务正在启动 ..
MySQL 服务已经启动成功。

用空密码登录：
C:\Users\duansf>mysql -u root -p
Enter password:

6.更改root密码:
mysql> UPDATE mysql.user SET password=PASSWORD("123456") WHERE user='root';
ERROR 1054 (42S22): Unknown column 'password' in 'field list'
mysql>


更改密码报错，因为新版5.7版本的mysql数据库下的user表中已经没有Password字段了,而是将加密后的用户密码存储于authentication_string字段
更改密码命令如下：

mysql> update MySQL.user set authentication_string=password('123456') where user='root';
Query OK, 1 row affected, 1 warning (0.02 sec)
Rows matched: 1 Changed: 1 Warnings: 1


mysql>
mysql>
mysql> flush privileges;
Query OK, 0 rows affected (0.13 sec)

7.用新密码登录:
d:\database\mysql-5.7.17-winx64\bin>mysql -u root -p
Enter password: ******
