Ubuntu 10.04 with full cluster stack support
+1 Vote Up -0Vote Down

Just in case you haven’t noticed, Ubuntu 10.04 “Lucid Lynx” has arrived. I upgraded my personal box over the weekend, and am happy to report that things went pretty flawlessly for me. So I’m now a happy lucid user.

What’s more important for the ever-growing cluster community is the fact that this LTS release comes with built-in support for the Pacemaker cluster stack — and indeed, it’s the first commercially-supported distribution that comes with support for both the Heartbeat and the Corosync cluster messaging layer. And it’s easy, too!

Here’s how I install the Pacemaker stack with Heartbeat

A big congratulations to Ubuntu for the release of 10.04 LTS. While I haven’t had the chance to upgrade, I see everyone on Twitter and in the blogosphere say they are really like the Lucid experience.

A couple of days ago, I made mention that there were VirtualBox images of MariaDB out there. Turns out there were so many downloads, Mark has had to upgrade his Internet connection!

Anyway, to the point: Mark has created Ubuntu

    When backups fail: A mysql binlog race condition
    +0 Vote Up -0Vote Down

    Today I ran into my first MySQL binlog race condition: The initial problem was quite simple: A typical MySQL master->slave setup with heavy load on the master and nearly no load on the slave, which only serves as a hot fallback and job machine, showed differences on the same table on both machines. The differences showed up from time to time: entries that have been deleted from the master were still on the slave.

    After several investigations I started examining the MySQL binlog from the master – a file containing all queries that will be transferred to the slave (and executed there if they don’t match any ignore-db-pattern). I grepped for ids of rows that have not been deleted on the slave as I’s interested if the DELETE statement was

    Well, for Matt Asay, I should start by congratulating you for the new job and nice title! (Also, we learn some intelligence from Matt's blog: apparently Canonical is already close to the size of MySQL AB at the time of the Sun acquisition.)

    Usually we are told to "ignore the trolls" and all that. The blogosphere unfortunately seems to be full of commentators who like to have share their opinion - even while they are entirely clueless. Sometimes, like the comments on Slashdot, it is ok and considered part of the entertainment. Sometimes it is harmless, because nobody reads that blog. And sometimes, it is just unacceptable:

    How To Set Up MySQL Database Replication With SSL Encryption On Ubuntu 9.10

    How To Set Up MySQL Database Replication With SSL Encryption On Ubuntu 9.10

    This tutorial describes how to set up database replication in MySQL using an SSL connection for encryption (to make it impossible for hackers to sniff out passwords and data transferred between the master and slave). MySQL replication allows you to have an exact copy of a database from a master server on another server (slave), and all updates to the database on the master server are immediately replicated to the database on the slave server so that both databases are in sync. This is not a backup policy because an accidentally issued DELETE command will also be carried out on the slave; but replication can help protect against hardware failures though.

    Ubuntu Karmic's Network Manager Issues
    +1 Vote Up -1Vote Down
    Since Ubuntu 8.04 aka Hardy Heron, I've had issues with every new release. As Ubuntu evolves into being a viable desktop OS alternative, its complexity has been growing and with the new and improved looks new challenges arise. This bug in particular has been very difficult to diagnose and I can't imagine anyone without enough Linux experience to overcome it on their own, so I decided to summarize the steps I took to fix it ... and vent my frustration at the end.

    The Symptom

    I came across the issue for the first time while trying Ubuntu's Karmic Netbook remix. After overcoming the typical Broadcom wifi driver, Network Manager would connect, but Firefox would fail to load the web pages 90% of the time. Using ping in the command line worked just fine. Maybe I needed to update the software packages to get the latest

    Fixing a MariaDB package bug
    +4 Vote Up -0Vote Down

    One of the things that I am really happy about in MariaDB is that we have our releases available as apt (and yum for Centos) repositories. This is largely thanks to being able to build this on the OurDelta package build infrastructure (which again builds on things like the Debian packaging scripts for MySQL).

    Something like the Debian apt-get package system (which is also used by Ubuntu) is one of the major innovations in the Free Software world in my opinion. Debian has spent many years refining this system to where it is today. Want to run the mysql client, but it isn't installed? Just try to run it on your local Ubuntu host:

        $ mysql
        The program 'mysql' can be found in the following packages:
         * mysql-client-5.0
         * mysql-client-5.1

    51 Weeks since my book writing adventure began

    In one week, on December 24th, it will be exactly one year since I was first contacted by Packt Publishing. After reading several posts from this blog they asked me if I’d be interested in writing a MySQL administration cookbook with hands-on recipes for those among us who have to make sure the MySQL servers are kept running and in good shape.

    Funny thing, I almost deleted their email, because initially I thought GMail’s spam filter had not caught some sort of bulk or phishing email, because I had never heard of Packt Publishing before and at first only saw an unfamiliar sounding sender’s name. As I was one of very few people in the office on that day I decided to read it anyways. Turned out to be not so spammy after all…

    MySQL on Debian and Ubuntu
    +3 Vote Up -0Vote Down

    Debian Linux (the underlying foundation of Ubuntu) manages the startup/shutdown of MySQL quite differently from the ways I am used to. I am a long-time user of both the MySQL binary provided by Red Hat/SuSE (along with Fedora and clones like CentOS and Oracle Enterprise Linux) and the official binary from mysql.com (http://www.mysql.com). After the successful restore of a cold backup, I started mysqld using the Debian provided init script. The script said that mysqld failed to start up, but in reality it did start up. Similarly, stopping mysqld fails.

    The output below demonstrates the outputs and the behavior seen on a Ubuntu 8.04 LTS Server:

    root:~# ps -ef | grep mysqld
    root     20165 19926  0 15:12 pts/4    00:00:00 grep mysqld
