This tutorial shows how to prepare a Debian 8 (Jessie) server (with nginx, BIND, Dovecot) for the installation of ISPConfig, and how to install ISPConfig 3.1. ISPConfig 3 is a web hosting control panel that allows you to configure the following services through a web browser: Apache or nginx web server, Postfix mail server, Courier or Dovecot IMAP/POP3 server, MySQL, BIND or MyDNS nameserver, PureFTPd, SpamAssassin, ClamAV, and many more. This setup covers nginx (instead of Apache), BIND as DNS server, and Dovecot (instead of Courier).

GitHub uses MySQL to store its metadata: Issues, Pull Requests,
comments, organizations, notifications and so forth. While
git repository data does not need MySQL to exist and
persist, GitHub’s service does. Authentication, API, and the
website itself all require the availability of our MySQL fleet.
Our replication topologies span multiple data centers and this poses a challenge not only for availability but also for manageability and operations.
We use a classic MySQL master-replicas setup, where the master is the single writer, and replicas are mainly used for read traffic. We expect our MySQL fleet to be available for writes. Placing a review, creating a new repository, adding a collaborator, all require write access to our backend database. We require the master to be available.
To that effect we employ automated master failovers. The time it would take a human to wake up …[Read more]

Facebook MyRocks at MariaDB spetrunia Wed, 12/07/2016 - 08:58
Recently my colleague Rasmus Johansson announced that MariaDB is
adding support for the Facebook MyRocks storage engine. Today I’m
going to share a bit more on what that means for MariaDB users.
Members of the Facebook Database Engineering team helped us
answer some questions we think our community will have about
Benefits of MariaDB Server’s Extensible Architecture
Before discussing specifics of MyRocks, new readers may benefit from a description of MariaDB Server architecture, which is extensible at every layer including the storage layer. This means users and the community can add functionality to meet unique needs. Community contributions are one of MariaDB’s greatest advantages over other databases, and a big reason for us becoming the fastest growing …
In the previous blog post, we have looked into the multi-host networking capabilities with Docker with native network and Calico. In this blog post, our journey to make Galera Cluster run smoothly on Docker containers continues. Deploying Galera Cluster on Docker is tricky when using orchestration tools. Due to the nature of the scheduler in container orchestration tools and the assumption of homogenous images, the scheduler will just fire the respective containers according to the run command and leave the bootstrapping process to the container’s entrypoint logic when starting up. And you do not want to do that for Galera - starting all nodes at once means each node will form a “1-node cluster” and you’ll end up with a disjointed system.

I’ve been lately compiling and generating .deb packages for several MySQL and MariaDB recent versions, and I wanted to try them more in depth -specially MySQL 8.0 and MariaDB 10.2, both of which are still in development.
Several people have already given their first impressions (or will do soon), and testing early is the best way to catch bugs and regressions, and get them fixed before the official release. In fact, as I will comment later, I ran into breaking bugs on both MySQL 8.0 and MariaDB 10.2, which I …[Read more]
Using the MariaDB Audit Plugin with MySQL geoff_montee_g Tue, 12/06/2016 - 15:10
The MariaDB audit plugin is an audit plugin that is bundled with MariaDB server. However, even though it is bundled with MariaDB, the plugin is actually compatible with MySQL as well. For a step-by-step guide on how to use the plugin with MySQL, check out my blog post here
Importing InnoDB Partitions in MariaDB 10.0/10.1 geoff_montee_g Tue, 12/06/2016 - 15:02
Transportable tablespaces for InnoDB tables is a very useful feature added in MySQL 5.6 and MariaDB 10.0. With this new feature, an InnoDB table’s tablespace file can be copied from one server to another, as long as the table uses a file-per-table tablespace.
Unfortunately, the initial transportable tablespace feature in MySQL 5.6 and MariaDB 10.0 does not support partitioned tables. Support for partitioned tables was added in MySQL 5.7. This feature will also likely be added to MariaDB 10.2 since it will contain …[Read more]
In MySQL 8.0.0 we introduced many new features; among those, we extended the bit-wise operations to work with binary data. Because of these changes, storing and manipulating IPv6 addresses can be done in an easier manner. In this blog we will take a look at how can you do this for some of the most common use cases.…
