mysql实现自动远程备份一办法_MySQL
一、实现本地自动备份数据库很简单：
1.以root身份登陆
2.计划任务（每天的3：30自动执行 /usr/bin/mysqlbackup）
crontab
0 3:30 * * * /usr/bin/mysqlbackup
3.写一个自动备份数据库脚本
vi /usr/bin/mysqlbackup
#!/bin/bash
mv /home/.../db_bak5.tgz /home/.../db_bak6.tgz
mv /home/.../db_bak4.tgz /home/.../db_bak5.tgz
mv /home/.../db_bak3.tgz /home/.../db_bak4.tgz
mv /home/.../db_bak2.tgz /home/.../db_bak3.tgz
mv /home/.../db_bak1.tgz /home/.../db_bak2.tgz
rm -rf /home/.../db_bak.txt
/usr/bin/mysqldump -uroot -ppassword dbname
> /home/.../db_bak.txt
cd /home/.../
tar czvf db_bak1.tgz db_bak.txt
二、这样每天的3：30就会在本地目录/home/.../下生成相应的数据库备份，开始由于/home/.../目录下缺少数据系统会提示错误，这是正常的
三、至于远程备份可以配合使用ftp或scp命令实现，方法很简单，查一下相关命令的使用，然后再改动一下mysqlbackup脚本就可以了
