MySQL replication monitoring on Ubuntu 10.04 with Nagios and NRPE

If you're using MySQL replication, then you're probably counting on it for some fairly important need. Monitoring via something like Nagios is generally considered a best practice. This article assumes you've already got your Nagios server setup and your intention is to add a Ubuntu 10.04 NRPE client. This article also assumes the Ubuntu 10.04 NRPE client is your MySQL replication master, not the slave. The OS of the slave does not matter.

Getting the Nagios NRPE client setup on Ubuntu 10.04

At first it wasn't clear what packages would be appropriate packages to install. I was initially misled by the naming of the nrpe package, but I found the correct packages to be:

sudo apt-get install nagios-nrpe-server nagios-plugins

The NRPE configuration is stored in /etc/nagios/nrpe.cfg, while the plugins are installed in /usr/lib/nagios/plugins/ (or lib64). The installation of this package …

Ornery Oneiric

I just updated to Ubuntu 11.10 “Oneiric” on one of my desktops and I ran into an issue with MariaDB.

It’s not an issue with MariaDB itself, more in how the MariaDB “Natty” .deb packages are configured. We haven’t released .deb packages for Ubuntu 11.10 “Oneiric”, but the Natty packages work fine, apart from this one configuration issue (and when we do release “Oneiric” packages, they will work out-of-the-box).

The main problem is that some things have moved around in “Oneiric” and Apparmor doesn’t like the MariaDB “Natty” Apparmor defaults file because it doesn’t account for some of the new destinations. Specifically, /var/run has been moved to /run (a discussion of the rationale behind the move can be found here). Other things have been moved too, but the /var/run to /run move is the one that is …

Running phpMyAdmin On Nginx (LEMP) On Debian Squeeze/Ubuntu 11.04

Running phpMyAdmin On Nginx (LEMP) On Debian Squeeze/Ubuntu 11.04

The phpMyAdmin package from the Debian/Ubuntu repositories comes with configuration files for Apache and Lighttpd, but not for nginx. This tutorial shows how you can use the Debian Squeeze/Ubuntu 11.04 phpMyAdmin package in an nginx vhost. Nginx is a HTTP server that uses much less resources than Apache and delivers pages a lot of faster, especially static files.

Open Query looking for new colleagues!

My colleagues and I are looking for extra talent – is that you?

What we do:help clients prevent problems (rather than being the fire department), we work on a subscription basis although we also do some ad-hoc consulting, and training. Apart from MySQL/MariaDB query and DBA work, we do quite a bit of system administration. Mainly Red Hat and Debian based distros, and expect to see replication and the MySQL-MMM multi-master system. You’d work from home, whereever it might be, so you will need to be self-motivating (but we do keep in touch online).

What we’re not: a full-time employer. With us, you make a life rather than a living. Everybody is contracted part-time. You can make enough to live comfortably, but that has nothing to do with hours. If you’re stressed about not filling all hours in your week with work-work-work, we’re not the company for you… there’s more to life than …

MySQL Clusters on Amazon EC2 - verified AMIs

We regularly receive questions from our user community with regards to which AMIs to use when deploying database clusters on Amazon EC2.

As part of our ongoing development work on the Severalnines Configurator and ClusterControl, we have recently done some testing on deploying MySQL Cluster on EC2 using Severalnines on three different AMIs. We thought we should share the results of these tests, hence the reason for this week's blog!

If you would like to test such a deployment yourself, feel free to use the parameters and guidelines below to do so. You can also check out these new videos to see Severalnines technology in …
