The latest from the MySQL community

Following my previous post on the launch, I just rolled Ubuntu 14.04 LTS on an Amazon EC2 t1.micro instance (not something you expect to run a database server on, for sure – 1 vCPU, 0.613GiB RAM). If you do an apt-cache search mysql you get 435 return result sets with the default configuration (trusty: main & universe).

If you do apt-get install mysql-server, you get MySQL 5.5. You enter the password of choice, and before you know it, MySQL is installed (a SELECT VERSION() will return 5.5.35-1ubuntu1).

Next you decide to install MariaDB. I run an apt-get install mariadb-server. It pulls in libjemalloc (for TokuDB) and I expect future releases to ship this engine by default. You enter the password, and you get a new message (as pictured).

Inspired by Yngve Svendsen’s post, I too think it makes absolute sense to congratulate Ubuntu on the 14.04 LTS release (some server notes - MySQL has a section dedicated to it). Ubuntu users have a lot of server choice today (that’s from all major MySQL ecosystem vendors):

• MySQL 5.5.35 ships in main. It is the default MySQL. Oracle has committed to providing updates to 5.5 throughout the LTS release cycle of Ubuntu (which is longer than the planned EOL for 5.5). This is why the grant of a Micro Release …

I’d like to congratulate Canonical with the new Ubuntu 14.04 LTS (Trusty Tahr) Release, it really looks like a great release, and I say it having my own agenda It looks even more great because it comes with a full line of Percona Software.
If you install Ubuntu 14.04 and run aptitude search you will find:

• Percona Toolkit
• Percona XtraBackup
• Percona XtraDB Cluster
• Percona Server (as part of Percona XtraDB Cluster installation)

Percona Toolkit and …

The Trusty Tahr is out with support for 5 years. Here are the first thoughts about it…

Stupid Browser comes up when searching “Appearance”

• Unity feels more responsive than ever, especially the Alt+Tab.
• New Desktop environments these days (also read as Cinnamon, GNOME Shell) take up a lot of RAM, I wanted to test 14.04’s unity, after few hours usage it too scooped up 320 MB worth of RAM… I expected better
• One thing that definitely annoyed me a lot – Everytime I pressed “Alt + D” (Firefox’s shortcut for address bar focus), the HUD used to come up after the address bar focus. Hence after each Alt+D, I had an “Escape key” following up. I hope Canonical listens to this, They might say “F6″ is an alternate shortcut …

A few things to note recently, amongst MariaDB in distributions. 

1. Ubuntu keeps MySQL 5.5 despite MariaDB’s success. There’s a lot of reasons for this, but remember the key takeaway here is MySQL 5.5 & the fact that MariaDB wasn’t even in Debian yet when the decision was made.
2. MariaDB is now inside of Debian/sid – check out the packages.
3. RHEL 7 comes with MariaDB 5.5 as a default; this is a good thing.

Now, from a distribution standpoint, we’re looking at starting to ship 10.0 as …

The procedure for using the PAM authentication plugin as documented doesn't work flawlessly on Ubuntu.

So here is how it works on Ubuntu (and probably also on other Debian based systems).

Please note that the PAM authentication plugin is an enterprise feature.

1. Make sure the plugin is loaded

This can be done by adding the following to the mysqld section of my.cnf (Don't forget to restart). You could also use INSTALL PLUGIN to load it without restart.

plugin-load=authentication_pam.so

2.  Add a user which will use the plugin

mysql> CREATE USER 'dveeden'@'localhost' IDENTIFIED WITH authentication_pam;
Query OK, 0 rows affected (0.00 sec)

3. Add a pam config file for 'mysql':
Create /etc/pam.d/mysql with the following …

We just announced Percona Server 5.6.14 release, and I decided to make this build with the TokuDB 7.1 engine.
The build is available here in the TESTING area.

You are welcome to play with these binaries, but keep in mind:

• This is an experimental build and not supposed to be used in production environment
• The binaries built on Ubuntu 12.04 LTS server and may not work on other Linux distributions
