生产环境下mysql分库备份与分表备份脚本

1.分库备份，库名手动提供

#!/bin/bash

MYUSER=root

MYPASS=123456

MYCMD="mysql -u$MYUSER -$MYPASS"

MYDUMP="mysqldump -u$MYUSER -p$MYPASS"

for database in beijing shanghai shenzhen

do

$MYDUMP $database |gzip > /tmp/backup/${database}_$(date +%F).sql.gz

done

2.分库备份，库名自动查询自动备份

#!/bin/bash

MYUSER=root

MYPASS=123456

MYCMD="mysql -u$MYUSER -p$MYPASS"

MYDUMP="mysqldump -u$MYUSER -p$MYPASS"

for database in `$MYCMD -e "show databases;"|sed '1,2d'|egrep -v 'mysql|test'`

do

$MYDUMP $database |gzip > /tmp/backup/${database}_$(date +%F).sql.gz

done

3.分表备份，库名表明均自动查询自动备份

#!/bin/bash

MYUSER=root

MYPASS=123456

MYCMD="mysql -u$MYUSER -p$MYPASS"

MYDUMP="mysqldump -u$MYUSER -p$MYPASS"

for database in `$MYCMD -e "show databases;"|sed '1,2d'|egrep -v 'mysql|test'`

do

    for table in `$MYCMD -e "show tables from $database;"|sed '1d'`

    do

    mkdir -p /tmp/backup/$database/

    $MYDUMP $database $table |gzip > /tmp/backup/$database/${database}_${table}_$(date +%F).sql.gz

    done

done
