一个简单的mysql备份脚本

一个简单的脚本 自己做个笔记 以后直接copy就好了 又变懒了#!/bin/bash
set -x
today=`date +%Y%m%d%H%M`
mkdir -p /data/backup/mysql/$today
/usr/local/mysql-5.1.60/bin/mysqldump -uroot -p'passwd' -h127.0.0.1 --master-data=2 --all-database > /data/backup/mysql/$today/backupdb.sqlfind /Data/mysqlbackup/mysql -type f -mtime +5 -exec rm {} \;
50 1 * * * /data/shell/mysqlback.sh
下面是借用 dngood的博客备份svn 数据,分两个脚本svn_data.sh 用于备份svn 数据到,远程rsync 服务器mysql_bak.sh 用于备份mysql 数据库到,远程rsync 服务器

备份MySQL数据库的命令mysqldump -hhostname -uusername -ppassword databasename > backupfile.sql备份MySQL数据库为带删除表的格式
