Update the Signing Key for Percona Debian and Ubuntu Packages

In this blog post, we’ll explain how to update the signing key for Percona Debian and Ubuntu packages.

Some of the users might have already noticed following warning on Ubuntu 16.04 (Xenial Xerus):

W: Signature by key 430BDF5C56E7C94E848EE60C1C4CBDCDCD2EFD2A uses weak digest algorithm (SHA1)

when running apt-get update.

Percona .deb packages are signed with a key that uses an algorithm now considered weak. Starting with the next release, Debian and Ubuntu packages are signed with a new key that uses the much stronger SHA-512 algorithm. All future package release will also contain the new algorithm.

You’ll need to do one of the …

It is ideal for building virtual development and testing environments. The solution is flexible and seamlessly integrates with popular CI tools.

Hello dear readers and attendees,

This is the post that I will be/ will have been referencing during my presentation to the Seattle Central Community College’s Byte club on Thursday, December 10th at 1500-1630.

I will begin with a bit of an autobio and find out what kind of students we have in attendance. Please feel free to comment if you’d like to keep in touch before or after the presentation. I will discuss some of the bits and pieces of some industry standard platforms which I’ve developed, deployed, maintained, managed, co-operated, administered and replaced. We can discuss some of the patterns that work well in the industry, and some that are a bit harder to tame.

Once we have touched most of the areas of specialization represented at the meeting, I will dive in to an AngularJS demo I am developing in github here:

Ubuntu Online Summit: MySQL & Variants in 16.04

I personally have always enjoyed the Ubuntu Developer Summits (UDS), but nowadays they have been converted to the Ubuntu Online Summits (UOS). Attending them is not always convenient (timezone issues, might be travelling, etc.) so I watched the recorded video of a session I was interested in: MySQL & Variants in 16.04.

My key takeaways

  1. Ubuntu 16.04 Xenial Xerus is an LTS release.
  2. The term “cross-grade” is used a lot (it is not about downgrading/upgrading, but being able to use MySQL or MariaDB or Percona Server interchangeably)
  3. It would be nice to see MySQL 5.7 in this release (for Xenial as well as Debian Stretch). From Oracle there is a new packager taking over the task (Lars)
  4. MySQL 5.5 is still the default in Debian, and there needs to be upgrades tested between 5.5 to 5.7 (it …

Installing Lighttpd with PHP5 (PHP-FPM) and MySQL on Debian 8 (Jessie)

Lighttpd is a secure, fast, standards-compliant web server designed for speed-critical environments. This tutorial shows how you can install Lighttpd on a Debian 8 (Jessie) server with PHP5 support (through PHP-FPM) and MySQL as a database server. PHP-FPM (FastCGI Process Manager) is a new PHP FastCGI implementation with some additional features useful for sites of any size, especially busier sites. I use PHP-FPM in this tutorial instead of Lighttpd's spawn-fcgi.
