Symantec published a blog post yesterday regarding MySQL and the Trojan.Chikdos.A as can be seen here

The Symantec post gives detail into the behavior of the Trojan and it’s effects on the Windows system registry, yet gives little detail as to how the required first stage (namely a malicious UDF) is injected, citing:

“In the latest Chikdos campaign that we observed, the attackers likely used an automated scanner or possibly a worm to compromise MySQL servers and install the UDF.”

I’m going to give my thoughts on the pre-requisites to infection here.

1. The MySQL server has poor network isolation (i.e. is likely accessible from everywhere e.g. …

LAMP is short for Linux, Apache, MySQL, PHP. This tutorial shows how you can install an Apache 2.4 web server on an Ubuntu 15.10 server with PHP 5 support (mod_php) and MySQL / MariaDB. Additionally, I will install PHPMyAdmin to make MySQL administration easier. A LAMP setup is the perfect basis for CMS systems like Joomla, Wordpress or Drupal.

During the last few weeks I’ve been testing and playing a bit with the new group-replication plugin available for MySQL 5.7. Before continuing I’d like to clarify some aspects: the plugin is only available in labs and is not yet ready for production. The current version is 0.6. I used 5.7.9 GA running in a Vagrant 3 nodes cluster with CentOS 7.
As an additional note, I’ve tested previous version of plugin 0.5 against 5.7.8.rc and there are some good changes, so I recommend starting with the GA version.

For the matter of my tests I’ve followed instructions from this post. It’s not as straightforward as it looks; there were some issues that needed to be handled, but I finally …

In our previous blog post we covered the deployment of four types of clustering/replication: MySQL Galera, MySQL master-slave replication, PostgreSQL replication set and MongoDB replication set. This should enable you to create new clusters with great ease, but what if you already have 20 replication setups deployed and wish to manage them with ClusterControl?

This blog post will cover adding existing infrastructure components for these four types of clustering/replication to ClusterControl and how to have ClusterControl manage them.

Adding an existing Galera cluster to ClusterControl

Adding an existing Galera cluster to ClusterControl requires: mysql user with the proper grants and a …

In the past, we’ve shared why you should love MySQL and how it helped Pinterest scale via sharding. At Oracle Open World today, we announced that we’re open-sourcing the vast majority of our automation that maintains our MySQL infrastructure. In this post, we’ll detail our MySQL environment, the tools used to manage it and how you can implement them to automate your MySQL infrastructure.

We've historically used MySQL to store some of our most important data, including Pins, boards, image metadata and …

In MySQL 5.7, we have enhanced the optimizer so that derived tables and views are handled more consistently.

Just to recap: A derived table is a subquery that can take the place of a table in the FROM clause of an SQL statement.…

The MySQL Router is a new building block for high availability solutions. MySQL Router simplifies development of high availability applications by intelligently routing queries to MySQL Servers for increased performance, robustness, and uptime. MySQL Router also helps in load balancing of read or write transactions to a database with support of multiple router connections to multiple clients.

There are various use cases where you can use multiple router connections.
- Write to a DB can be routed using one router and read can be happened by multiple router connections to have a better performance and stability
- If client and servers are in specific region , we can use multiple routers in the specific region
- Different warehouse can be handled by multiple routers considering the load.

These are few examples usecases. You can define your own usecase and check if it suites your environment. Also you …

MySQL Fabric is an extensible framework for managing farms of MySQL Servers. Two primary features have been implemented - High Availability (HA) and scaling out using data sharding. These features can be used in isolation or in combination.

MySQL Fabric setup is a process in which you need to run different commands in a sequence and use the corresponding logs for future reference. This blog tells about an easy process to do the initial setup of a Fabric system using config file. You need to define the properties file as per your requirement and run a similar python script while will do the setup.
Note: This fabric setup script is basically for release 1.5.6 or less and it is tested in our test environment.

Precondition:
- Fabric manage Setup and manage start is already triggered.
- Database is created OR shard servers have database already present.

Recently at Percona Live Amsterdam I gave a talk titled Databases in the Hosted Cloud (I’m told I got a 4/5 rating for this talk). It was before AWS re:Invent, so obviously some of the details in the talk have changed. For one, now there is also Amazon RDS for MariaDB. But there has also been other changes, i.e. HP’s Public Cloud (HP Helion Public Cloud) will sunset January 31 2016.

That’s a slide from my deck. I basically have to …

Adding good content to Twitter can be a pain. I can’t do it during working hours, and I don’t have much time at night. But, the more content you have, the more followers you can gain, and the more your original tweets can be seen (hopefully). I have written several posts about using the latest Perl-Twitter API – Net::Twitter::Lite::WithAPIv1_1, so you might want to check these out as well.

– Use MySQL and Perl to automatically find, follow and unfollow twitter users

– Using Perl to retrieve direct messages from Twitter, insert messages into a MySQL database and then …
