使用MYSQL数据库的朋友,对MySQL进行备份和还原是比较重要的。重要的事简单做,,今天介绍我们使用mysqldump和source命令来备份还原,分为Windows下和Linux下的MYSQL备份与还原操作。
一、Win32系统下MySQL的备份还原方法
备份:在“运行”中输入“cmd ”,利用“cd /Program Files/MySQL/MySQL Server 5.0/bin”进入bin文件夹,输入“mysqldump -u 用户名 -p databasename >exportfilename”导出数据库到文件,如mysqldump -u root -p voice>voice.sql,然后输入密码即可开始导出MYSQL数据,实现备份操作。
还原:进入MySQL Command Line Client,输入密码,进入到“mysql>”,输入命令"show databases;",回车,看看有些什么数据库;建立你要还原的数据库,输入"create database voice;",回车;切换到刚建立的数据库,输入"use voice;",回车;导入数据,输入"source voice.sql;",回车,开始导入,再次出现"mysql>"并且没有提示错误即还原成功。
二、Linux下MySQL的备份与还原方法:
备份:[root@localhost ~]# cd /var/lib/mysql (进入到MySQL库目录,根据自己的MySQL的安装情况调整目录)
[root@localhost mysql]# mysqldump -u root -p voice>voice.sql,输入密码即可。
还原:有两种方法可选:
第一种方法:[root@localhost ~]# mysql -u root -p 回车,输入密码,进入MySQL的控制台"mysql>",同1.2还原。
第二种方法:
[root@localhost ~]# cd /var/lib/mysql (进入到MySQL库目录,根据自己的MySQL的安装情况调整目录)
[root@localhost mysql]# mysql -u root -p voice
