Knowing which privileges a given account has is easy – just issue SHOW GRANTS FOR user@host.  But what about when you need visibility into privileges from the other direction – which accounts can access specific data?  If you’re a DBA – or perform DBA duties, regardless of your title – you may have been asked this question.  It’s an important question to ask in an audit or compliance review – but it can be a difficult question to answer.    This post will walk through how to assess this, but if you’re impatient and need answers to this question immediately, jump to the end – there’s a simple shortcut.

Things to consider

There are a few things you’ll want to consider about the implementation of the MySQL privilege system as you try to sort out who has access to certain data.

Access type

MySQL can restrict privileges based on operations – somebody who has …

We work on data recoveries quite often. In many cases, we recover table structures from the .frm files because there was no backup available. There is already a great blog post by my colleague Miguel Ángel Nieto about how we can recover structures from .frm files using MySQL utilities.

This works pretty well and we prefer to run mysqlfrm with the “–server” option to get all possible information from a .frm file. However, this option expects that MySQL is up and running so that mysqlfrm can spawn a new MySQL instance, and run the structure recovery there.

Recently I came across a tool that makes this job easier. The name of tool is …

We have thousands of databases and each database has many partitioned tables. In order to efficiently create and maintain partitions we developed a partition manager which automatically manages these for you with minimal pre configuration.

Today, we’re releasing MySQL Partition Manager. You can check out the code on GitHub.

We’re looking forward to interacting with the MySQL community and continue developing new features.

Having written the Building MaxScale from source on Centos7 tutorial, we have received requests about writing one for Ubuntu. It seems the most mentioned version is the 14.04 LTS version so we’re going to go with that. For the purpose of this tutorial, I’ve installed a fresh installation of Ubuntu 14.04.3 LTS (Trusty Tahr) on a VM.

MaxScale is a bit more complicated to build on Ubuntu and Debian, but should still be something almost everyone can do.

Installing basic packages

We start off by installing tools that we will need when building MaxScale. The list of required packages for each distribution can be found from the documentation: Building-MaxScale-from-Source-Code

Installing packages:

sudo apt-get install build-essential libssl-dev \
libaio-dev ncurses-dev bison cmake perl libtool \
librabbitmq-dev libcurl4-openssl-dev libpcre3-dev
