HomeDatabaseMysql Tutorial如何导入MySQL数据库_MySQL

  1.概述

  MySQL数据库的导入,有两种方法:

  1)先导出数据库SQL脚本,再导入;

  2)直接拷贝数据库目录和文件。

  在不同操作系统或MySQL版本情况下,直接拷贝文件的方法可能会有不兼容的情况发生。

  所以一般推荐用SQL脚本形式导入。下面分别介绍两种方法。

  2.方法一SQL脚本形式

  操作步骤如下:

  2.1.导出SQL脚本

  在原数据库服务器上,可以用phpMyAdmin工具,或者mysqldump命令行,导出SQL脚本。

  2.1.1用phpMyAdmin工具

  导出选项中,选择导出“结构”和“数据”,不要添加“DropDATABASE”选项。

  选中“另存为文件”选项,如果数据比较多,可以选中“gzipped”选项。

  将导出的SQL文件保存下来。

  2.1.2用mysqldump命令行

  命令格式

  mysqldump-u用户名-p数据库名>数据库名.sql

  范例:

  mysqldump-uroot-pabc>abc.sql

  (导出数据库abc到abc.sql文件)

  提示输入密码时,输入该数据库用户名的密码。

  2.2.创建空的数据库

  通过主控界面/控制面板,创建一个数据库。假设数据库名为abc,数据库全权用户为abc_f。

  2.3.将SQL脚本导入执行

  同样是两种方法,一种用phpMyAdmin(mysql数据库管理)工具,或者mysql命令行。

  2.3.1用phpMyAdmin工具

  从控制面板,选择创建的空数据库,点“管理”,进入管理工具页面。

  在"SQL"菜单中,浏览选择刚才导出的SQL文件,点击“执行”以上载并执行。

  注意:phpMyAdmin对上载的文件大小有限制,php本身对上载文件大小也有限制,如果原始sql文件

  比较大,可以先用gzip对它进行压缩,对于sql文件这样的文本文件,可获得1:5或更高的压缩率。

Adding MySQL users through the PHP web interface can use MySQLi extensions. The steps are as follows: 1. Connect to the MySQL database and use the MySQLi extension. 2. Create a user, use the CREATEUSER statement, and use the PASSWORD() function to encrypt the password. 3. Prevent SQL injection and use the mysqli_real_escape_string() function to process user input. 4. Assign permissions to new users and use the GRANT statement.
