How To Back Up MySQL Databases With mylvmbackup On Debian Lenny

How To Back Up MySQL Databases With mylvmbackup On Debian Lenny

mylvmbackup is a Perl script for quickly creating MySQL backups. It uses LVM's snapshot feature to do so. To perform a backup, mylvmbackup obtains a read lock on all tables and flushes all server caches to disk, creates a snapshot of the volume containing the MySQL data directory, and unlocks the tables again. This article shows how to use it on a Debian Lenny server.

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
    Try: sudo apt-get install <selected package>
    -bash: mysql:

DRBD has entered a new phase. After being developed out of tree for 9 years, and after an extended review and streamlining phase since March, Phil submitted DRBD to be merged into 2.6.32 release of the Linux mainline kernel. The submission was accepted by block layer maintainer Jens Axboe, who merged DRBD in September, then deferred to the 2.6.33 merge window, and this morning Linus

Due to a bug in britney, the Debian testing migration tool, MySQL is currently not available in testing. The issue is known and being worked on already, and it is documented in the Debian bug tracking system.

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

You can now apt-get your way to MariaDB 5.1, courtesy of OurDelta and in close cooperation with Monty Program Ab. To get started, simple follow the info on the Debian and Ubuntu pages.

Quick overview

  • For MariaDB we use different repository directories to ensure that you can’t accidentally upgrade or revert major versions without you explicitly choosing to do so.
  • At this point we have Ubuntu Hardy, Intrepid, Jaunty and Karmic for you, as well as Debian 4 (Lenny). Etch (Debian 4) is waiting on a small fix (thanks to Antony Curtis for helping with that).

MySQL 5.1 moved to Debian unstable

Thanks to Christian Hammers, we finally have MySQL 5.1 in Debian unstable, which completely replaces MySQL 5.0. Please update all build-dependencies from libmysqlclient15-dev to libmysqlclient-dev and upload a rebuild version of your package.

As a positive side-effect, we no longer care about MySQL bug #41728, which was the reason why no newer version of MySQL 5.0 made it into testing since lenny got released.

Debian unstable on a Sun Fire T1000
+0 Vote Up -0Vote Down

So i got the T1000 working again (finally, after much screwing about trying to get the part). I then hit the ever annoying “no console” problem, where the console didn’t work – kind of problematic.

After a firmware upgrade, and passing “console=/dev/ttyS0″ to the kernel, things work.

So the T1000 firmware 6.3 doesn’t work with modern debian kernels. Thing swork with 6.7 though.

libmemcached packages

Ronald Bradford last week posted about memcached not being multi-threaded on Ubuntu, something he discovered via some small utilities that are bundled with libmemcached, written by Brian Aker.

When I noticed there were no Ubuntu packages for libmemcached (or the CLI tools) I decided to create some.

For your enjoyment: http://ubuntu.cafuego.net/dists/jaunty-cafuego/memcached/ (Source debs are included)

The repository also contains a memcached that has been re-compiled with multithreading enabled.

How To Set Up WebDAV With MySQL Authentication On Apache2 (Debian Lenny)

This guide explains how to set up WebDAV with MySQL authentication (using mod_auth_mysql) on Apache2 on a Debian Lenny server. WebDAV stands for Web-based Distributed Authoring and Versioning and is a set of extensions to the HTTP protocol that allow users to directly edit files on the Apache server so that they do not need to be downloaded/uploaded via FTP. Of course, WebDAV can also be used to upload and download files.

Recovering a crashed MySQL server

After a server crash (meaning the system itself or just the MySQL daemon) corrupted table files are quite common. You’ll see this when checking the /var/log/syslog, as the MySQL daemon checks tables during its startup.

Using Dtrace to find out if the hardware or Solaris is slow (but really just working around the problem)
+0 Vote Up -0Vote Down

A little while ago, I was the brave soul tasked with making sure Drizzle was working properly and passing all tests on Solaris and OpenSolaris. Brian recently blogged about some of the advantages of also running on Solaris and the SunStudio compilers - more warnings from the compiler is a good thing. Many kudos goes to Monty Taylor for being the brave soul who fixed most of the compiler warnings (and for us, warnings=errors - so we have to fix them) for the SunStudio compilers before I got to making te tests work.

So, I got to the end of it all and got pointed to an OpenSolaris x86 box where the drizzleslap test was timing out. The timeout for tests is some amazingly long amount of time - 15 minutes. All the drizzle-test-run tests are rather short tests.

Help with Debian MySQL packages required

During the last few months I was the only person working on the MySQL packages in Debian, and I could really need some help. Currently there is MySQL 5.0.32 in etch, 5.0.51a in lenny, 5.0.75 in unstable and 5.1.31 in experimental, and I am also trying to get MySQL Cluster and MySQL Workbench into Debian. All in all it is way too much work for only one developer.

Debian releases Lenny, MySQL 5.1 soon
+0 Vote Up -0Vote Down

Congratulations to the Debian team for releasing Debian GNU/Linux 5.0 Lenny on Valentine’s Day. This version comes with MySQL 5.0.51a.

I had been pestering Norbert Tretkowski to see when MySQL 5.1 will move from experimental to main, and he told me once Lenny was released. This is because Debian itself needs to make a library transition from libmysqlclient15 to libmysqlclient16, and every package that links to libmysqlclient will need to rebuild against the new version. It couldn’t be done any earlier, and now that Lenny is released, we should start seeing MySQL 5.1 in Debian/unstable, real soon now.

So, if you’re a Debian user, know that you have 5.0.51a in stable (Lenny), 5.0.75 in unstable, and

Installing PowerDNS (With MySQL Backend) And Poweradmin On Debian Etch

This article shows how you can install the PowerDNS nameserver (with MySQL backend) and the Poweradmin control panel for PowerDNS on a Debian Etch system. PowerDNS is a high-performance, authoritative-only nameserver - in the setup described here it will read the DNS records from a MySQL database (similar to MyDNS), although other backends such as PostgreSQL are supported as well. Poweradmin is a web-based control panel for PowerDNS.
