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. 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: Read the rest of this entry . . .

Considering my recent update to Ubuntu 9.10, I decided to have another go at getting TOra up and running. This time I am tackling a 64-bit system rather than the 32-bit “Hardy Heron” I had done previously.
On my way, I found some odd issues that I will describe here. All in all, it was a good few hours of cobbling together the pieces I needed to proudly present to you . . .
Installing TOra with Oracle support on Ubuntu 9.04 (Jaunty Jackalope)
Conventions and Caveats
- I use
sudo for everything because logging in to root shells is just bad practice.
- I plug vi whenever possible, because vi is the greatest (and to annoy emacs people).
- I did this all in a KDE desktop, which means that some things I say may sound like I use KDE. Commands issued are in pre-formatted text without any prompt gunk in front of them, so cut and paste to your heart’s content.
- Output is also in pre-formatted text and I use it sparingly where relevant. Apt likes to output lots of text. I think it’s lonely.
- Some instructions are pasted from the original so you will not need to refer to my last howto to get this working. For an all-new jocular experience, no attempts at humour were recycled.
- When I say “dep”, I actually mean dependancy.

Welcome, readers! It’s time for another update to our series of posts on installing Oracle on Ubuntu Linux. In this edition, we’ll be installing Oracle 11g R1 on Ubuntu 9.04, both 32-bit.
This time, I’ve used VirtualBox to run a virtual machine (VM) to perform our work. (Virtualization has a number of advantages; in this case, I made several trial installs, trying different combinations and configurations. Having a pristine, basic set-up accelerated the whole process, since I didn’t had to reinstall from scratch on every new attempt.)
You might want to review the previous editions of this series, as there are technical references on this text fully detailed on previous posts. See these HOWTOs for Ubuntu:
Since we’re installing on a VM, we’ll be using Ubuntu 9.04 32-bit Server edition, , so let’s download it and check the MD5sum:
user@jackalope:/media/trezentos/downloads$ md5sum ubuntu-9.04-server-i386.iso
20480057590ff8b80ad9094f40698030 ubuntu-9.04-server-i386.iso
user@jackalope:/media/trezentos/downloads$
Download Oracle Database 11g Release 1 (11.1.0.6.0), and verify the provided cksum:

Hello, there! With another Ubuntu release, it has come the time to update our series of posts on how to install Oracle 11g on Ubuntu. If you’ve been following, we’ve been publishing updated howtos since Ubuntu 7.04:
In fact, in this article I refer several times to previous posts regarding some configuration aspects and why I chose particular values. Also, note that this series of posts is a work in progress and we were able to improve this series with your help. So please do post comment below as your collaboration is very much appreciated.
In this post, we’ll see the steps needed to install Oracle 11gR1 on an Ubuntu 8.10 Intrepid Ibex box all the way to creating your very first database. I’ve been working very hard to ensure that at every new post, the results you get when executing this procedure are as deterministic as possible, leading to a successful setup.
Please keep in mind that this is not a supported architecture, so pay special attention to the order in which I do things. Don’t rush and try to merge steps, as it took me a lot of attempts to make this setup work properly. There are some reboots and also there’s a specific order you need to do things, so please follow the instructions step-by-step and verify the the results of every single command.
Preparation
Let’s get down to it, shall we? The first thing to do is to get some files. We need an ISO image of Ubuntu (a CD/DVD will do) and one of Oracle 11gR1. Get Ubuntu 8.10 Server here; and Oracle 11gR1 here. (It’s free, but you have to register on the Oracle website to download it.)
It’s a good idea to check the md5sum of each image after downloading from the Internet.

I have put up a poll on my personal blog, Diamond Notes asking whether you prefer Ubuntu or Debian as an operating system for MySQL server. I am curious because I have seen a shift in the last year of Debian users to the Ubuntu distribution, and I would like to put some actual numbers to what I am seeing. (Please don’t vote if you use another OS or another Linux distribution, as I am strictly interested in the usage patterns of these two operating systems.)
Thanks,
Keith.

The highlight today of probably every Linux-related mailing list and IRC channel was the announcement of CVE-2008-0166, affecting OpenSSL libraries on Debian-based Linux distributions, including the popular Ubuntu.
According to the Debian Security Advisory, a change made to Debian’s OpenSSL package makes its random number generator predictable. Obviously this is less than desirable in a random number generator used for things like, say, all of your SSH keys.
The vulnerability has been present since September of 2006, and Debian strongly suggests throwing your old keys out completely:
It is strongly recommended that all cryptographic key material which has been generated by OpenSSL versions starting with 0.9.8c-1 on Debian systems is recreated from scratch.
Debian has now disabled public key authentication on their project servers until further notice, and are generating new keys for those servers and new certificates for db.debian.org.
So all you Debian and Ubuntu folks out there will probably want to do the same for your own keys and certificates. Note that this patch was never used by the upstream OpenSSL team nor by other distros like Fedora or RHEL (or CentOS), so they are not affected.
