Lighttpd is a secure, fast, standards-compliant web server designed for speed-critical environments. This tutorial shows how you can install Lighttpd on a Centos 7 server with PHP support (through PHP-FPM) and MySQL support. PHP-FPM (FastCGI Process Manager) is an alternative PHP FastCGI implementation with some additional features useful for sites of any size, especially busier sites. I use PHP-FPM in this tutorial instead of Lighttpd's spawn-fcgi.

Stockholm, Sweden and anywhere else in the world - 20 April 2016 - Severalnines, the provider of database infrastructure management software, today announced its latest customer, the National Center for Scientific Research (CNRS), which is a subsidiary of the French Ministry of Higher Education and Research.

The CNRS has over 1,100 research units and is home to some of the largest scientific research facilities in the world. It partners with other global institutions and employs over 33,000 people. Working in partnership with universities, laboratories and dedicated scientists, CNRS has delivered advanced research in areas such as obesity, malaria and organic matter in space.

Having an international outreach means they have a dedicated department to handle the information infrastructure of the organisation called the Directorate of Information Systems (CNRS-DSI). Thousands of …

Percona Live is humming along, and we had quite a whirlwind keynote session this morning. Bill Nye the Science Guy gave an amazing talk, Bill Nye’s Objective – Change the World, on how the process of science and critical thinking can help us not only be positive about the challenges we face in our world today, but also help us to come up with the big ideas we need to solve them. He discussed many topics, from how his parents met, their involvement in science (his mother worked on the Enigma Code in World War 2!), working at Boeing as an engineer, his involvement with Carl Sagan, and how he has worked to help harness renewable energy through solar panels, a solar water heater, and skylights at his own …

Different types of languages deal with this "value" in diverse ways. You can have a more comprehensive list of what NULL can mean on this website. What I like to think about NULL is along the lines of invalid, as if some sort of garbage is stored there. It doesn't mean it's empty, it's just mean that something is there, and it has no value to you.

Databases deal when storing this type in a similar way, PostgreSQL treats it as "unknown" while MySQL treats it as "no data".

Both databases recommend using \N to represent NULL values where import or exporting of data is necessary.

When to use it

In my last I was looking for a way to do performance monitoring and I stumbled upon Prometheus. Prometheus is much more than monitoring a single node service. Anyway let’s get the idea of gathering metrics using MySQL as example.

This how a simple configuration of Prometheus could look like:

global: 
  scrape_interval: 1m
  scrape_timeout: 10s
  evaluation_interval: 1m

scrape_configs:
  - job_name: mysql
    scheme: http
    target_groups:
    - targets: 
        - '10.17.148.31:9104'
      labels:
        zone: mysql

Every minute Prometheus accesses 172.17.148.31:9104/metrics (/metrics is a Prometheus convention) and labels the result with zone=mysql. Querying the data you can use the labels.

This is a simple configuration. The fun of Prometheus is to have a lot of targets/jobs.

Let’s have a look at our specific endpoint: …

We’re moving along on the first day at Percona Live Data Performance Conference 2016, and I was able to attend a lecture from Intel’s Ken LeTourneau on Performance of Percona Server for MySQL on Intel Server Systems using HDD, SATA SSD, and NVMe SSD as Different Storage Mediums. In this talk, Ken reviewed some benchmark testing he did using MySQL on various types of storage mediums. This talk looked at the performance of Percona Server for MySQL for Linux running on the same Intel system, but with three different storage configurations. We looked at and compared the performance of:

1. a RAID of HDD
2. a RAID of SATA SSD
3. a RAID of NVMe SSD

In the talk,  Ken covered the hardware and system …

Today was day one of the Percona Live Data Performance Conference! The day began with some excellent keynote speakers and exciting topics, and the packed room was eager to hear what our speakers had to say!
