### auth: Jin
### date: 20140402
### Desc: 根据配置文件里的ip,端口(dblist文件格式为192.168.201.245:3303:sso:root:passwd)，数据库名dump备份mysql数据，清理指定天前的备份文件，通过ssh隧道追加同步到其他IDC服务器上
### Usage: ./dump_mysqldatabase.sh

BACKDIR=/data/BackupPC/database
LIST=${BACKDIR}/dblist
BACKUPLOG=${BACKDIR}/dump_mysqldatabase.log
TODAY=`date +%F`
DELDAY=`date -d "7 day ago" +%F`
NUM=$(cat $LIST | wc -l)
DUMPBIN=/usr/local/mysql/bin/mysqldump
RSYNCBIN=/usr/bin/rsync

echo " " >> $BACKUPLOG
echo "###########################" >> $BACKUPLOG
echo "`date +%F/%T` $1" >> $BACKUPLOG
