MySQL备份脚本

MySQL分库备份脚本 # cat /scripts/mysql_store_backup.sh

#!/bin/bash

MYPASS="123456"
SOCKET=/tmp/mysql.sock
MYLOGIN="mysql -uroot -p$MYPASS -S $SOCKET"
MYDUMP="mysqldump -uroot -p$MYPASS -S $SOCKET -B --single-transaction --all-databases  --flush-logs"
DATABASE="$($MYLOGIN -e "show databases;" |egrep -vi "Data|_schema|mysql")"

for dbname in $DATABASE
do
MYDIR=/backup/$dbname
[ -d $MYDIR ] || mkdir -p $MYDIR
$MYDUMP $dbname|gzip >$MYDIR/${dbname}_$(date +%F).sql.gz
done

MySQL分库分表备份脚本 # cat /scripts/mysql_table_backup.sh

#/bin/bash

MYPASS="123456"
SOCKET=/tmp/mysql.sock
MYLOGIN="mysql -uroot -p$MYPASS -S $SOCKET"
MYDUMP="mysqldump -uroot -p$MYPASS -S $SOCKET -B --single-transaction --all-databases  --flush-logs"
DATABASE="$($MYLOGIN -e "show databases;" |egrep -vi "Data|_schema|mysql")"

for dbname in $DATABASE
do
TABLE="$($MYLOGIN -e "use $dbname;show tables;" |sed '1d')"
for tname in $TABLE
do
MYDIR=/backup/$dbname
[ -d $MYDIR ] || mkdir -p $MYDIR
$MYDUMP $dbname $tname|gzip >$MYDIR/${dbname}_${tname}$(date +%F).sql.gz
done
done

MySQL增量备份脚本,(增量备份是基于 binlog 日志的) # cat /scripts/mysql_zl_back.sh
