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

row in set (0.00 sec) 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 | |
+------+-----------+-------------------------------------------+
rows in set (0.00 sec)
