完整备份方案,将所有数据库备份后,进行打包压缩归档,同时删除原备份文件。
#!/bin/bash
SQL_name=''dbname1 dbname2 dbname3……dbnameN-1 dbnameN''   #数据库名称;
SQL_pwd='123456'                        #数据库密码;
SQL_path='/usr/local/mysql/bin'        #数据库命令目录;
BACKUP_tmp=/data/backup/tmp     #备份文件临时存放目录;
BACKUP_path=/data/backup           #备份文件压缩打包存放目录;
for i in $SQL_name
do
$SQL_path/mysqldump -uroot -p$SQL_pwd $i > $BACKUP_tmp/$i-$(date +%y-%m-%d-%H-%M)。sql
sleep 3
done
sleep 60
