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
Copy after login
