How to install MySQL Server on Debian Stretch

For the impatient:

# echo -e "deb http://repo.mysql.com/apt/debian/ stretch mysql-5.7\ndeb-src http://repo.mysql.com/apt/debian/ stretch mysql-5.7" > /etc/apt/sources.list.d/mysql.list
# wget -O /tmp/RPM-GPG-KEY-mysql https://repo.mysql.com/RPM-GPG-KEY-mysql
# apt-key add /tmp/RPM-GPG-KEY-mysql
# apt update
# apt install mysql-server

In the latest stable version of Debian, if you ask to install mysql-server, you now get installed mariadb automatically, with no (evident) way of installing Oracle’s MySQL. Any major version upgrade has to be done carefully (not only for MariaDB, but also for MySQL and Postgres), and I bet that a MySQL 5.5 to MariaDB 10.1 will cause a huge confusion. Not only it will fail user expectations, I think this will cause large issues now that MariaDB has chosen to become a “hard” fork, and become incompatible in many ways with MySQL. Not only the server upgrade will cause user struggle, the connector is …

MySQL & NoSQL – Memcached Plugin

Many of you have already heard about NoSQL databases and one of the the most used tool is Memcached, where you add a cache layer between the application and database. Since MySQL version 5.6, a new plugin is available to do the integration between MySQL and Memcached. On this article, we will learn how to install it on linux, and some basic configurations of it.

Pre-requirements:
Install libevent

Installation:
To install memcached support we will need to create a few tables responsible for MySQL and memcached integration. MySQL already includes the file which creates those tables (innodb_memcached_config.sql), you can find this file in a sub folder of your basedir. To discover where is your basedir, run the bellow command:

mysql> SHOW VARIABLES LIKE 'basedir';
+---------------+-------+
| Variable_name | Value |
+---------------+-------+
| basedir       | /usr  | …

How to install MySQL 5.6 on CentOS 7

A bit of history

The latest version of Red Hat Enterprise Linux, one of the most popular and respected Linux distributions in the server market, was released in June 2014, followed by CentOS 7 and Oracle Linux releases in July of the same year.

There are very interesting changes for database administrators in these new releases, among which I would like to highlight the fact that installer now chooses XFS as its filesystem by default, which substitutes ext4 as the preferred format for local data storage. Red …

MariaDB 10.0 reference card: plugins in packages

MariaDB 10.0 comes with ~50 engines and plugins; and it comes in 35 package sets (34 binary ones and a source tarball).

Every day people come asking on #maria IRC whether a package X contains an engine Y, or saying that it doesn’t, or wondering if it should. Remembering all combinations isn’t easy, and it became impractical to study build logs or package contents every time, so I ended up with a cheat sheet for 10.0.10 GA. At the very least it should help me to answer those questions; even better if somebody else finds it useful.

The tables below refer to contents of packages provided at downloads.mariadb.org or at MariaDB repository mirrors. Packages built by distributions might have different contents and are not covered here.

Legend

— built-in (also known as static):
the plugin comes as a part of the server binary. It can be disabled or enabled by default, but even when it is disabled, it is …
