I'd like to congratulate Canonical with the new Ubuntu 14.04 LTS ( Trusty Tahr) Release , it really looks like a great release, and I say it having my own agenda It looks even more great because it comes with a full line of Percona Software.

If you install Ubuntu 14.04 and run aptitude search you will find:

Percona Toolkit

Percona XtraBackup

Percona XtraDB Cluster

Percona Server (as part of Percona XtraDB Cluster installation)

upgrade to Percona 5.6

upgrade to Redis 2.8 for Lua and SCAN support

upgrade to nginx 1.5 for SSL performance improvements

switch from unicorn to Puma for memory efficiency

Conclusion

…hard-to-recover problems. Here's Baron Schwartz, MySQL God at Percona, on MMM's flaws :

In short, MMM causes more downtime than it prevents. It's a Low-Availability tool, not a High-Availability tool. It only takes one really good serious system-wide mess to take you down for a couple of days, working 24×7 trying to scrape your data off the walls and put it back into the server. MMM brings new meaning to the term "cluster-f__k".

Generate a new template with correct polling interval - by default all Percona templates are shipped configured for 5-minute polling intervals. To change that you need to re-generate them using a procedure explained in their documentation . If you're using their RPM package to deploy the scripts, here is a command that worked for me:

Other the last few days, the Percona team has spent a lot of time evaluating the impact of the Heartbleed bug ( CVE-2014-0160) for our customers and for the users of our software. We published a formal disclosure a few days ago. However, I thought a quick summary and some additional information would be good to provide for our MySQL Performance Blog readers.
