mysql表备份脚本

今天看了老男孩库表份脚本的视频，自己整理了一下

#!/bin/bash
HOSTNAME=root
MYPASS=abcd1234
SOCK=/var/lib/mysql/mysql.sock
DATE=$(date +%F)
MYCMD="mysql -u$HOSTNAME -p$MYPASS -S $SOCK"
MYDUMP="mysqldump -u$HOSTNAME -p$MYPASS -S $SOCK"
for date in $($MYCMD -e "show databases" | sed '1,2d')
do
   mkdir /backup/${date} -p
     for table in $($MYCMD -e "show tables from $date" | sed '1d')
     do
       $MYDUMP $date $table|gzip >/backup/${date}/${date}_${table}_$DATE.sql.gz
     done
done

运行结果如下

[root@www backup]# tree /backup
