在musql的目录新建一个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=c:mysqlmysql-5.7.17-winx64

设置mysql数据库的数据的存放目录

datadir=c:mysqlmysql-5.7.17-winx64data

允许最大连接数

max_connections=500

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

以管理员身份打开cmd窗口后，将目录切换到你mysql安装目录的bin目录,分别执行下面语句

mysqld --initialize-insecure --user=mysql
mysqld install
net start mysql

然后输入

mysql -u root -p

提示输入密码，直接敲回车即可登录，登录之后执行SET PASSWORD = PASSWORD('123456');修改密码为123456

然后就可以通过mysql -u root -p123456登录了，记住-p和密码之间是没有空格的。

添加mysql的普通用户sun_mysql，密码设置为123456

create user 'sun_mysql'@'localhost' identified by '123456';

设置该用户运行指定IP访问

GRANT ALL PRIVILEGES ON . TO 'sun_mysql'@'%' IDENTIFIED BY '123456' WITH GRANT OPTION;
flush privileges;

在root用户下创建testdb库

grant all privileges on testdb.* to 'sun_mysql'@'%' identified by '123456';
flush privileges;

如果需要修改设置该用户只允许本机访问输入
delete from user where user = 'sun_mysql' and host != 'localhost';
GRANT ALL PRIVILEGES ON . TO 'sun_mysql'@'localhost' IDENTIFIED BY '123456' WITH GRANT OPTION;
flush privileges;

如果设置mysql运行指定的IP访问
GRANT ALL PRIVILEGES ON . TO 'sun_mysql'@'110.110.110.46' IDENTIFIED BY '123456' WITH GRANT OPTION;
flush privileges;
