Installing Nginx With PHP5 (And PHP-FPM) And MySQL Support On CentOS 6.0

Installing Nginx With PHP5 (And PHP-FPM) And MySQL Support On CentOS 6.0

Nginx (pronounced "engine x") is a free, open-source, high-performance HTTP server. Nginx is known for its stability, rich feature set, simple configuration, and low resource consumption. This tutorial shows how you can install Nginx on a CentOS 6.0 server with PHP5 support (through PHP-FPM) and MySQL support.

CB1 Ubuntu 10.10 Linux Development Setup

I use a MacBook Pro for my day-to-day operations here at CB1, INC. I’m a huge believer that a development environment should mimic the production environment, so I find myself running a couple virtual machines in VMware Fusion.

The following guide is a reference for myself as well as possibly a helpful resource for setting up your own Linux development environment. Here’s an checklist of the tasks to perform and software to install:

  • Operating System
    • Ubuntu 10.10 64-bit: I use Ubuntu Desktop in dev and Ubuntu Server in production
    • Package updates and upgrades
    • Network configuration (at least 2 static IP addresses)
  • Development Tools
    • C/C++ development environment
    • Autotools
    • Sun Java JDK

Nginx-Fu: X-Accel-Redirect From Remote Servers

We use nginx and its features a lot in Scribd. Many times in the last year we needed some pretty interesting, but not supported feature – we wanted nginx X-Accel-Redirect functionality to work with remote URLs. Out of the box nginx supports this functionality for local URIs only. In this short post I want to explain how did we make nginx serve remote content via X-Accel-Redirect.

First of all, here is why you may need this feature. Let’s imagine you have a file storage on Amazon S3 where you store tons of content. And you have an application where you have some content downloading functionality that you want to be available for logged-in/paying/premium users and/or you want to keep track of downloads your users perform …

Advanced Squid Caching in Scribd: Cache Invalidation Techniques

Having a reverse-proxy web cache as one of the major infrastructure elements brings many benefits for large web applications: it reduces your application servers load, reduces average response times on your site, etc. But there is one problem every developer experiences when works with such a cache – cached content invalidation.

It is a complex problem that usually consists of two smaller ones: individual cache elements invalidation (you need to keep an eye on your data changes and invalidate cached pages when related data changes) and full cache purges (sometimes your site layout or page templates change and you need to purge all the cached pages to make sure users will get new visual elements of layout changes). In this post I’d like to look at a few techniques we use at …

Enabling IPv6 Support in nginx

This is going to be a really short post, but for someone it could save an hour of life.

So, you’ve nothing to do and you’ve decided to play around with IPv6 or maybe you’re happened to be an administrator of a web service that needs to support IPv6 connectivity and you need to make your nginx server work nicely with this protocol.

First thing you need to do is to enable IPv6 in nginx by recompiling it with --with-ipv6 configure option and reinstalling it. If you use some pre-built package, check if your nginx already has this key enabled by running nginx -V.

The results should have --with-ipv6 option in configure arguments:

1

3
4
5
[root@node ~]# nginx …

Advanced Squid Caching in Scribd: Hardware + Software Used

After the previous post in this caching related series I’ve received many questions on hardware and software configuration of our servers so in this post I’ll describe our server’s configs and the motivation behind those configs.

Hardware Configuration

Since in our setup Squid server uses one-process model (with an asynchronous requests processing) there was no point in ordering multi-core CPUs for our boxes and since we have a lots of pages on the site and the cache is pretty huge all the servers ended up being highly I/O bound. Considering these facts we’ve decided to use the following hardware specs for the servers:

CPU: One pretty cheap dual-core Intel Xeon 5148 (no need in multiple cores or really high frequencies – even these CPUs have ~1% avg load)
RAM: 8Gb (basically …

Advanced Squid Caching in Scribd: Logged In Users and Complex URLs Handling

It’s been a while since I’ve posted my first post about the way we do document pages caching in Scribd and this approach has definitely proven to be really effective since then. In the second post of this series I’d like to explain how we handle our complex document URLs and logged in users in the caching architecture.

First of all, let’s take a look at a typical Scribd’s document URL: http://www.scribd.com/doc/1/Improved-Statistical-Test.

As we can see, it consists of a document-specific part (/doc/1) and a non-unique human-readable slug part (/Improved-Statistical-Test). When a user comes to the site with a wrong slug in the document URL, we need to make sure we send the user to the correct …

Version 1.1.2 of improved Cacti templates released

I’ve packaged up and released version 1.1.2 of the Cacti templates I’ve written for MySQL, Apache, memcached, nginx etc.

Anyone who would like to help write documentation (or do anything else, for that matter) is welcomed to participate. I’ll give commit access at the drop of a hat.

Changelog:

2009-05-07: version 1.1.2

        * The parsing code did not handle InnoDB plugin / XtraDB (issue 52).
        * The servername was hardcoded in ss_get_by_ssh.php (issue 57).
        * Added Handler_ graphs (issue 47).
        * Config files can be used instead of editing the .php file (issue 39).
        * binary log space is now calculated without a MySQL query (issue 48).
        * There was no easy way to force inputs to be filled (issue 45).
