#!/bin/bash
#MySQL分库自动备份方案
MYSQL_LIST=$(mysql -e "show databases"|grep -v "Database")
MYSQL_DIR=mysql_backup_`date +%F`
[ ! -d $MYSQL_DIR ] && mkdir $MYSQL_DIR
for i in $MYSQL_LIST

MySQL sub-table automatic backup scheme:

[root@localhost ~]# vim mysql_tables.sh

#!/bin/bash
#MySQL分库自动备份方案
MYSQL_LIST=$(mysql -e "show databases"|grep -v "Database")
MYSQL_DIR=mysql_backup_`date +%F`
[ ! -d $MYSQL_DIR ] && mkdir $MYSQL_DIR
for i in $MYSQL_LIST
do
        for j in `mysql -e "use $i;show tables;"|grep -v "Tables_in_mysql"`
        do
                mysqldump -uroot ${i} ${j} > ${MYSQL_DIR}/${i}_${j}.sql 2>/dev/null
        done
done

Execute the script:

[root@localhost ~]# sh mysql_tables.sh
