Mysql备份与恢复

#!/bin/sh
dir=/home/atj/data/tmp
echo -------DB_Publish-------`
if [ ! -e $dir ]; then
        mkdir -p $dir
fi

backup() {
        aip=$1
        user=$2
        pass=$3
        db=$4
        name=$5
        file=$dir/$name.sql
        if [ ! -f $file ];then
                touch $file
        fi
        mysqldump -h$aip -u$user -p$pass $db > $file #数据库备份命令
        if [ $? != 0 ]; then
                echo "ERROR:Database $db backup fail!!!"
		  exit 0
        else
                echo "SUCCESS:Database $db backup success! "
        fi
}

        backup $1 $2 $3 db_atj source_backup

        backup $4 $5 $6 db_atj target_backup

        mysql -h$4 -u$5 -p$6 db_atj1 < $dir/source_backup.sql #数据库恢复操作
        if [ $? != 0 ]; then
                echo "ERROR:Database publish error !!!"
		  exit 0
        else
                echo "SUCCESS:Database publish success !!!"
        fi
exit 0
