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 = 3306 # 设置mysql的安装目录 basedir=E:mysql-5.7.14-winx64 # 设置mysql数据库的数据的存放目录 datadir=E:mysql-5.7.14-winx64data # 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
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-winx64my.ini"
net start mysql
E:mysql-5.7.14-winx64in>mysqld --initialize-insecure E:mysql-5.7.14-winx64in>mysqld --install Service successfully installed. E:mysql-5.7.14-winx64in>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 | +-----------+-----------+ 2 rows in set (0.00 sec) mysql> grant all on *.* to root@'%' identified by '123456'; Query OK, 0 rows affected, 1 warning (0.00 sec) mysql> select user,host from mysql.user; +-----------+-----------+ | user | host | +-----------+-----------+ | root | % | | mysql.sys | localhost | | root | localhost | +-----------+-----------+ 3 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 = 3307 # 设置mysql的安装目录 basedir=E:mysql-5.6.32-winx64 # 设置mysql数据库的数据的存放目录 datadir=E:mysql-5.6.32-winx64data # 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
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-winx64my.ini"
net start mysql5.6
E:mysql-5.6.32-winx64in>mysqld --initialize-insecure 2019-05-23 16:07:54 0 [Warning] TIMESTAMP with implicit DEFAULT value is depreca ted. Please use --explicit_defaults_for_timestamp server option (see documentati on for more details). 2019-05-23 16:07:54 0 [Note] mysqld (mysqld 5.6.32) starting as process 2492 ... E:mysql-5.6.32-winx64in>mysqld --install mysql5.6 Service successfully installed. E:mysql-5.6.32-winx64in>net start mysql5.6 mysql5.6 服务正在启动 . mysql5.6 服务已经启动成功。
登陆MySQL5.6服务
E:mysql-5.6.32-winx64in>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-5.6.32-winx64in>mysql -u root -P 3307 Welcome to the MySQL monitor. Commands end with ; or g.

Type 'c' to clear the current input statement. mysql> mysql> select user(); +----------------+ | user() | +----------------+ | root@localhost | +----------------+ 1 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('000000') where user='root' and h ost='localhost'; Query OK, 1 row affected (0.00 sec) Rows matched: 1 Changed: 1 Warnings: 0 mysql> flush privileges; Query OK, 0 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('000000') where user ='root' and host='localhost'; Query OK, 1 row affected, 1 warning (0.00 sec) Rows matched: 1 Changed: 1 Warnings: 1 mysql> flush privileges; Query OK, 0 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 | ::1 | | | | localhost | | +------+-----------+-------------------------------------------+ 4 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 '000000'; Query OK, 0 rows affected (0.00 sec) mysql> flush privileges; Query OK, 0 rows affected (0.00 sec) mysql> select user,host,password from mysql.user; +------+-----------+-------------------------------------------+ | user | host | password | +------+-----------+-------------------------------------------+ | root | % | *032197AE5731D4664921A6CCAC7CFCE6A0698693 | | root | 127.0.0.1 | | | root | ::1 | | | | localhost | | +------+-----------+-------------------------------------------+ 4 rows in set (0.00 sec)
