Windows安装MySQL免安装版

安装环境：

win7 64位

IP地址：192.168.2.37

防火墙已经关闭

一、安装MySQL5.7.14免安装版

1、解压文件

2、新建my.ini文件

data文件夹自动生成

my.ini里面内容为:

[mysql]
# 设置mysql客户端默认字符集
default-character-set=utf8
[mysqld]
#设置3306端口
port =
# 设置mysql的安装目录
basedir=E:\mysql-..-winx64
# 设置mysql数据库的数据的存放目录
datadir=E:\mysql-..-winx64\data
# 允许最大连接数
max_connections=
# 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

3、配置环境变量，避免每次都要到安装目录下的bin里面执行。

4、初始化数据、安装服务、启动MySQL

以管理员的身份运行cmd，将目录切换到你mysql安装目录的bin目录

mysqld --initialize-insecure

执行 mysqld --initialize-insecure 指令进行配置，安装路径会默认生成一个data文件夹

mysqld --install mysql

也可以指定配置文件进行安装服务

mysqld --install --defaults-file="E:\mysql-5.7.14-winx64\my.ini"

net start mysql

E:\mysql-5.7.-winx64\bin>mysqld --initialize-insecure

E:\mysql-5.7.-winx64\bin>mysqld --install
Service successfully installed.

E:\mysql-5.7.-winx64\bin>net start mysql
MySQL 服务正在启动 .
MySQL 服务已经启动成功。

5、用户设置

cmd到bin目录下执行mysql -uroot （无需密码） ， 即可进入，因为上边是用insecure 创建的

创建一个root用户，并设置密码

MariaDB [aa]> grant all on *.* to root@'%' identified by '123456';

mysql> select user,host from mysql.user;
+-----------+-----------+
| user      | host      |
+-----------+-----------+
| mysql.sys | localhost |
| root      | localhost |
+-----------+-----------+
 rows in set (0.00 sec)

mysql> grant all on *.* to root@'%' identified by '';
Query OK,  rows affected,  warning (0.00 sec)

mysql> select user,host from mysql.user;
+-----------+-----------+
| user      | host      |
+-----------+-----------+
| root      | %         |
| mysql.sys | localhost |
| root      | localhost |
+-----------+-----------+
 rows in set (0.00 sec)

客户端连接成功

二、安装MySQL5.6.32免安装版

1、解压文件

2、新建my.ini文件

my.ini里面内容如下:

[mysql]
# 设置mysql客户端默认字符集
default-character-set=utf8
[mysqld]
#设置3307端口
port =
# 设置mysql的安装目录
basedir=E:\mysql-5.6.-winx64
# 设置mysql数据库的数据的存放目录
datadir=E:\mysql-5.6.-winx64\data
# 允许最大连接数
max_connections=
# 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

3、初始化数据、安装服务、启动MySQL

mysqld --initialize-insecure

mysqld --install mysql5.6

也可以指定配置文件进行安装服务

mysqld --install mysql5.6 --defaults-file="E:\mysql-5.6.32-winx64\my.ini"

net start mysql5.6

E:\mysql-5.6.-winx64\bin>mysqld --initialize-insecure
-- ::  [Warning] TIMESTAMP with implicit DEFAULT value is depreca
ted. Please use --explicit_defaults_for_timestamp server option (see documentati
on for more details).
-- ::  [Note] mysqld (mysqld 5.6.) starting as process  ...

E:\mysql-5.6.-winx64\bin>mysqld --install mysql5.
Service successfully installed.

E:\mysql-5.6.-winx64\bin>net start mysql5.
mysql5. 服务正在启动 .
mysql5. 服务已经启动成功。

登陆MySQL5.6服务

E:\mysql-5.6.32-winx64\bin>mysql -u root -P 3307

第一次登录没有密码

-u root指定root用户登陆

-P 指定MySQL端口号3307

E:\mysql-5.6.-winx64\bin>mysql -u root -P

mysql>

4、设置root密码

语法：

mysql> update user set password=password(“新密码”) where user=”用户名” and host='localhost';

实例：

mysql> update mysql.user set password=password('000000') where user='root' and host='localhost';

刷新内存生效

mysql> flush privileges;

mysql> update mysql.user set password=password('') where user='root' and h
ost='localhost';
Query OK,  row affected (0.00 sec)
Rows matched:   Changed:   Warnings: 

mysql> flush privileges;
Query OK,  rows affected (0.00 sec)

执行如果报错：ERROR 1054 (42S22): Unknown column 'password' in 'field list'

请把password字段改成了authentication_string

mysql> update mysql.user set authentication_string=password('123456') where user='root' and host='localhost';

刷新内存生效

mysql> flush privileges;

mysql> update mysql.user set authentication_string=password('') where user
='root' and host='localhost';
Query OK,  row affected,  warning (0.00 sec)
Rows matched:   Changed:   Warnings: 

mysql> flush privileges;
Query OK,  rows affected (0.01 sec)

查看所有用户信息

mysql> select user,host,password from mysql.user;

mysql> select user,host,password from mysql.user;
+------+-----------+-------------------------------------------+
| user | host      | password                                  |
+------+-----------+-------------------------------------------+
| root | localhost | *032197AE5731D4664921A6CCAC7CFCE6A0698693 |
| root | 127.0.0.1 |                                           |
| root | ::       |                                           |
|      | localhost |                                           |
+------+-----------+-------------------------------------------+
 rows in set (0.00 sec)

执行授权命令

mysql> grant all privileges on *.* to root@'%' identified by '000000';

mysql> grant all privileges on *.* to root@'%' identified by '';
Query OK,  rows affected (0.00 sec)

mysql> flush privileges;
Query OK,  rows affected (0.00 sec)
mysql> select user,host,password from mysql.user;
+------+-----------+-------------------------------------------+
| user | host      | password                                  |
+------+-----------+-------------------------------------------+
| root | %         | *032197AE5731D4664921A6CCAC7CFCE6A0698693 |
| root | 127.0.0.1 |                                           |
| root | ::       |                                           |
|      | localhost |                                           |
+------+-----------+-------------------------------------------+
