Given the amount of time since my last post on installing OurDelta MySQL on EC2. It allowed me to show quickly how to get your OurDelta MySQL install up-to-date.
Prerequisites:
You have already installed the OurDelta Repository as per this documentation
http://ourdelta.org/centos
To update:
Now just yum update to get the latest version:
http://ourdelta.org/release-5077-d8
yum update MySQL-OurDelta*
It is as simple as that.
Comments:
Thanks for the feedback from the last post.
Some people requested the Amazon Machine Image (AMI). The main issue with this is, once you bundle an AMI image it is going to start with those binaries (including mysql) and require you to constantly run yum update each time you launch an instance. So if I had bundled an AMI back in February, anyone using that AMI now would be way behind on the latest updates for OurDelta and also any other CentOS packages.
It is better to go down the path of learning how to bundle an AMI yourself, then getting an base CentOS 4 or CentOS 5 AMI up-to-date once month and using yum update afterwards, when you launch the instance.
You can even pass a script which runs after the instance has launched, or use a configuration tool like Puppet.
Believe me when I say that whilst bundling AMIs is straight-forward you do not want large numbers of old/obsolete AMIs floating around to manage later.
Upcoming stuff:
I am going to use this AMI with MySQL Sandbox to show how easy it is to have a test environment if you want to take your existing MySQL 5.0.x versions to OurDelta MySQL or any other version on MySQL.
Have Fun

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then run:
/usr/bin/mysql_secure_installation
which will also give you the option of removing the test
databases and anonymous user created by default. This is
strongly recommended for production servers.
See the manual for more instructions.
MySQL bug reports should be submitted through http://bugs.mysql.com/
Issues related to the OurDelta patches or packaging should be
submitted in the OurDelta project on Launchpad, simply follow the

Notes regarding SELinux on this platform:
=========================================
The default policy might cause server startup to fail because it is
not allowed to access critical files. In this case, please update
your installation.
The default policy might also cause inavailability of SSL related
features because the server is not allowed to access /dev/random
and /dev/urandom. If this is a problem, please do the following:
1) install selinux-policy-targeted-sources from your OS vendor
2) add the following two lines to /etc/selinux/targeted/src/policy/domains/program/mysqld.te:
allow mysqld_t random_device_t:chr_file read;
allow mysqld_t urandom_device_t:chr_file read;
3) cd to /etc/selinux/targeted/src/policy and issue the following command:
make load

Complete!
Just make sure the mysql instance is secure
[root@domU-12-31-39-04-71-D3 ~]# /usr/bin/mysql_secure_installation
NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQL
SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!
In order to log into MySQL to secure it, we'll need the current
password for the root user. If you've just installed MySQL, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.
Enter current password for root (enter for none):
OK, successfully used password, moving on...
Setting the root password ensures that nobody can log into the MySQL
root user without the proper authorisation.
You already have a root password set, so you can safely answer 'n'.
Change the root password? [Y/n] n
... skipping.
By default, a MySQL installation has an anonymous user, allowing anyone
to log into MySQL without having to have a user account created for
them. This is intended only for testing, and to make the installation
go a bit smoother. You should remove them before moving into a
production environment.
Remove anonymous users? [Y/n]
... Success!
Normally, root should only be allowed to connect from 'localhost'. This
ensures that someone cannot guess at the root password from the network.
Disallow root login remotely? [Y/n]
... Success!
By default, MySQL comes with a database named 'test' that anyone can
access. This is also intended only for testing, and should be removed
before moving into a production environment.
Remove test database and access to it? [Y/n]
- Dropping test database...
... Success!
- Removing privileges on test database...
... Success!
Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.
Reload privilege tables now? [Y/n]
... Success!
Cleaning up...
All done! If you've completed all of the above steps, your MySQL
installation should now be secure.
Thanks for using MySQL!
