One way to achieve this is to write a bash script: (Source)

#! /bin/bash

TIMESTAMP=$(date +"%F")
BACKUP_DIR="/backup/$TIMESTAMP"
MYSQL_USER="backup"
MYSQL=/usr/bin/mysql
MYSQL_PASSWORD="password"
MYSQLDUMP=/usr/bin/mysqldump

mkdir -p "$BACKUP_DIR/mysql"

databases=`$MYSQL --user=$MYSQL_USER -p$MYSQL_PASSWORD -e "SHOW DATABASES;" | grep -Ev "(Database|information_schema|performance_schema)"`

for db in $databases; do
  $MYSQLDUMP --force --opt --user=$MYSQL_USER -p$MYSQL_PASSWORD --databases $db | gzip > "$BACKUP_DIR/mysql/$db.gz"
done

For more information, have a look at this similar question.
