This article will explain the installation and usage of mytop, a handy tool for live monitoring of MySQL queries. Also looking into various operations that a user can perform while monitoring the queries on mytop.

I helped a charity to rebuild a MySQL server and to restore a database with a lot of data of longblob type in the last two days. Fortunately there was a dump backup file for the database in question.

However, tables with longblob column(s) were not defined with “ROW_FORMAT=COMPRESSED”. I’d like to restore that database with row compression before inserting the data. Therefore I need to modify the dump sql file. The problem is that the file is 2.5 GB and the server only has 4 GB memory. So editing it is a challenge. Fortunately, Linux has sed to save the day. Don’t you love open source free software?

I am power Vi/Vim user, so I am familiar with sed and have used it in the past. But there are still a few things that I searched around for quick answers. So I’ll record noteworthy points here. I couldn’t remember how many times my own past blog entries helped me over the years. And I hope you’ll find this helpful too! …

Last week, Canonical invited the MySQL packaging team in Debian to a packaging sprint in their London office, and most of us were able to participate. We’ve met online on IRC and UOSs before, but this was the first time we were all in the same room.

The results of our sprint will soon be available in a .deb near you. Since Debian Jessie is currently in feature freeze, most of it will hit Ubuntu first. The two main things we achieved on the MySQL side were to make MySQL 5.6 ready for Ubuntu Vivid (15.04) and to split MySQL, Percona and MariaDB configuration files. The configuration file split …

Did your logging stop working after you set up logrotate? Then this post might be for you.

Archive your log files!

Some time ago, Peter Boros wrote about Rotating MySQL Slow Logs safely, explaining the steps of a “best practice” log rotate/archive. This post will add more info about the topic.

When running logrotate for MySQL (after proper setting the /etc/logrotate.d/mysql conf file) from anacron, there’s a situation that you might potentially face if the user and password used to execute the “flush logs” command is stored in, for example, /root/.my.cnf file.

The situation:

You might find out that you have a new MySQL log file ready to receive data, but nothing is being written to it.

Why did this happen?

The logrotate script is executed, but the postrotate …
