mysql数据库的导入导出可以用数据库备份工具mysqldump
mysqldump工具是mysql自带的一个非常方便的一款小工具,存在mysql安装目录的/usr/local/mysql/bin (CentOS)是下。
mysqldump 和 mysql一样,都是应用程序,你在mysql下是执行不了的。切记 ,输入 mysqldump –help 可查年相关信息。mysqldump可以任何目录下直接执行。
一、导出
用 mysqldump 备份数据库
1 | mysqldump -u用户 -p密码 数据库名 > (目录)导出文件名 |
如:mysqldump -uroot -p123 dbname > /root/test.sql 回车就直接完成备份。
如果只需要建表指令,则命令如下: shell> mysqldump -u root -p -d dbname > test.sql
如果只需要插入数据的sql命令,而不需要建表命令,则命令如下: shell> mysqldump -u root -p -t dbname > test.sql
备份单个数据表
有时候数据库很大,整个库备份就不好管理,那就单独备份。
1 | mysqldump -uroot -p123 dbname tablename > /root/testtb.sql |
备份多个数据表
例如备份wordpress数据库的wp_posts表和wp_options表到wordpress_1.sql:
1 | mysqldump -u root -p wordpress wp_posts wp_options > wordpress_1.sql |
mysqldump 远程备份
1 | mysqldump -h ip -uroot -p123 database > c:\nowamagic.sql |
二、导出
mysql>source /root/test.sql

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.
