这是我写的一个自动备份MYSQL的 脚本, 能备份所有MYSQL 中的所有数据库。

#!/bin/bash

umask 177

MUSER="userid"

MPASS="password"

MHOST="localhost"

MYSQL="$(which mysql)"

MYSQLDUMP="$(which mysqldump)"

PARAMS="--hex-blob --skip-extended-insert --password=$MPASS"

DATE="$(date +%F)"

BACKUPDIR="/home/${MUSER}/BACKUP/$DATE/"

RMDATE="$(date -d "1 week ago" +%F)"

RMDIR="/home/${MUSER}/BACKUP/$RMDATE"

BACKUPLOG="/home/${MUSER}/BACKUP/backup.log"

if [ ! -f $BACKUPLOG ] ; then

touch $BACKUPLOG

chmod 600 $BACKUPLOG

fi

if [ -d $RMDIR ]; then

rm -rf $RMDIR

echo "Backup DELETED from" $RMDATE >> $BACKUPLOG

fi

if [ ! -d $BACKUPDIR ]; then

mkdir -m 700 -p $BACKUPDIR

fi

echo "Backup BEGINNING" $DATE >> $BACKUPLOG

DBS="$($MYSQL -h $MHOST -u $MUSER -p$MPASS -Bse 'show databases')"

for db in $DBS

do

$MYSQLDUMP $PARAMS $db > $BACKUPDIR$db.sql && bzip2 --best $BACKUPDIR$db.sql

done

echo "Backup COMPLETED" $DATE >> $BACKUPLOG

另外可以结合CRONJOB定时备份
