备份脚本：mysql-dump.sh
#!/bin/bash export MYSQL_HOME=/usr/local/Percona-Server-5.5.21-rel25.0-227.Linux.x86_64/ export PATH=$MYSQL_HOME/bin:$PATH mysql_dump_dir=/data/backup/mysqldump mysql_username="YOURS" mysql_password="YOURS" mysql_databases="DBNAME1 DBNAME2 DBNAME3" timeStart=$(date '+%Y%m%d%H%M%S') sqlfile=$mysql_dump_dir/dump-$timeStart.sql mysqldump --opt --user=$mysql_username --password=$mysql_password -B $mysql_databases --max_allowed_packet=1048576 --net_buffer_length=16384 > $sqlfile
恢复时：使用root账号登陆到mysql命令行，执行：
source /data/backup/mysqldump/dump-20120629181412.sql
或者直接在linux的终端输入以下命令也可以
mysql -uYOURS -pYOURS -e"source /data/backup/mysqldump/dump-20120629181412.sql"
