mysql 자동 백업을 위한 스크립트 작성 방법입니다.

#!/bin/sh

_USERNAME="root"
_PASSWORD="비번"
_BACKUP_DIR="/backup/db/"
c_time="3"
/usr/bin/mysqladmin -u $_USERNAME -p$_PASSWORD reload >& /dev/null
mkdir -p $_BACKUP_DIR$(date +%Y%m%d)
now_db=`echo "show databases" | /usr/bin/mysql -u $_USERNAME -p$_PASSWORD`
num=1
for dir in $now_db ; do
if [ $dir != "Database" ]; then
/usr/bin/mysqldump -u $_USERNAME -p$_PASSWORD \
--databases $dir > $_BACKUP_DIR$(date +%Y%m%d)/$dir-$(date +%Y%m%d).sql
echo "Database - $dir - Backup Complete!!"
num=$(($num+1))
fi

find $_BACKUP_DIR* -ctime $c_time -exec rm -rf {} \;
done
