记录下mysql的一些常识

Windows xp环境：

1. 启动服务

net start mysql 运行一次后，后续windows会自动配置随机启动。

2. 设置配置文件

mysql-x.x.xx-winx64（小编的是5.6.17根据自己的版本来定）目录下，新建个my.ini。

3. 登录mysql服务

输入mysql -uroot -p ,默认是没有密码的

设置密码的方法：mysqladmin -u root -p password 密码。

4. 使用

F:\JAVA\mysql-5.6.25-win32\bin>mysql -uroot -p

Enter password:

6. log存放地方的设置 (这几步骤是错的！！！)

log=存放日志的路径/my.log

保存文件，重启服务之后，在“G:\Program Files (x86)\MySQL\MySQL Server 5.0\data”目录下可以找到“mySQL.log”文件。

7. 创建数据库

mysql创建数据库命令：1.show databases //显示数据库

2.create database student(数据库名) //创建数据库student

3.use student //进入student数据库

4.create table studinfo(表名) (sno ...详情>>

mysql> show databases;(复数，带s且带分号)

4 rows in set (0.14 sec)

mysql> create database test;
