ERROR: Invalid position '1'

This error drove me mad. I had searched the interwebs at least a few times for it and couldn’t find a solution. All I wanted to do was block some lame ass script kiddie from scanning my server. I know the ufw command I was entering was fine, because it […]

How to stop Wordpress pingback DDoS attacks

Yesterday I had the privilege of dealing with a Wordpress pingback DDoS attack on one of my sites. My hosting company, whom I pay for access to a DDoS protection appliance, didn’t even notice anything. They deployed the appliance at my request and the spike in inbound bandwidth subsided. Unfortunately, […]

sudo without password

I’ve recently run into deployment scenarios where I need to have a unprivileged user account execute something privileged like restarting nginx. Sure, I could just do things with the root account, but most of my deployments are done via SSH commands and I don’t allow root logins directly on my […]

Upgrade from PHP 5.3 to PHP 5.6 on Ubuntu 12.04 LTS

Last week I posted a call to action to help sway Ondřej Surý into continuing to support Ubuntu 12.04 LTS with his amazing PPA for the latest and greatest PHP versions. Ondřej was kind enough to take the time to backport the PPA and without ado, here’s how to get […]

Call to Action: PHP 5.6 on Ubuntu 12.04 LTS

I’m going to take a break from posting code snippets and how-tos to draw attention to the fact that PHP 5.6 may not be coming to Ubuntu 12.04 LTS by way of Ondřej Surý’s amazing PPA. Yes, you can still compile PHP from source, but as you may already know, […]

Upgrade to PHP 5.6 on Ubuntu 14.04 LTS

PHP 5.6 is finally here and if you’re on Ubuntu 14.04 LTS you’re stuck with an older version of PHP. If you want to take advantage of the new awesomeness, you can do so very easily thanks to a PPA. If you’ve never added a PPA before, you will want […]

How to Install PHP Redis on Ubuntu 14.04 LTS

Previously, I had shown you how to install PHP Redis from source but things changed with the latest Ubuntu LTS release. Now you can install the phpredis extension from the Ubuntu respositories. First, if you don’t have it installed already, let’s install Redis: sudo apt-get install redis-server After we get […]

How to Install the MongoDB PHP Module on Ubuntu 14.04 LTS

Installing the PHP module for MongoDB on Ubuntu 14.04 LTS is just a command away, but first, let’s ensure that we have MongoDB itself installed: sudo apt-get install mongodb Once we have MongoDB installed, we can proceed with installing the module. Please note that you could combine these commands to […]

How to Setup a LEMP Stack on Ubuntu 14.04 LTS

Last week I covered setting up a LAMP server on Ubuntu 14.04 LTS but for my money, it’s all about LEMP stacks. The “E” actually stands for Nginx (pronouced Engine X) and it’s an altnerative to the Apache web server that is built for speed and has a very low […]

How to Setup a LAMP Stack on Ubuntu 14.04 LTS

The newest long term support release of Ubuntu (Trusty Tahr) is finally here! I just spun up a droplet over on DigitalOcean to walk through setting up a LAMP stack for this post. I also recommend making sure that your system is completely up to date. At the time of […]

Upgrade from PHP 5.3 to PHP 5.4 on Ubuntu 10.04 LTS

I’ve previously posted about upgrading to PHP 5.5.x on Ubuntu 12.04 LTS but what about my friends still on the even older Ubuntu Long Term Service release that’s still supported, 10.04 LTS. That particular version’s server release will remain supported until April 2015, with more than a year left at […]

Your stack is outdated

I’ve been noticing a pattern with most of my peers (yes I said most), they expect their users to be running the latest and greatest version of their favorite “modern” browser and all the while their server stack is collecting dust. Ubuntu doesn’t help matters with their Long Term Service […]

Upgrade from PHP 5.3 to PHP 5.5 on Ubuntu 12.04 LTS

Recently I made the decision to stop living in the past and start living in the present by using the latest stable release of PHP, version 5.5.8. Unfortunately on Ubuntu 12.04 LTS (I always run LTS releases on my servers) the latest version of PHP available is from the 5.3 […]

PHP segmentation faulting from logging too much

At least I think that’s what was happening. Today I made the somewhat calculated risk of upgrading my production server from PHP 5.3.10 to PHP 5.5.7. Scary stuff, jumping 2 point revisions like that but I was feeling cocky after jumping 3 point revisions to bring nginx up to the […]

How to set up a LAMP server on Ubuntu 13.10

Been a while since I’ve covered setting up a brand new LAMP server. This time, I’m going to be using Ubuntu 13.10 and once you are logged into your server you will want to update and upgrade it to the latest software versions: sudo apt-get update && apt-get upgrade Once […]

Simplifying Single Server Deployments

Last week I discussed the importance of version control for individuals but something I didn’t touch on was how version control systems can be used to simplify and/or automate deployments. I’ve been through the different setups out there, using plain old rsync, leveraging GitHub’s Post-Receive WebHook to call a URL […]

Speed up PHP with APC

The Alternative PHP Cache (APC) is a PECL package that provides an opcode cache for PHP. Rasmus Lerdorf is the lead of the project along with a handful of other developers. What is an opcode cache? Before I can answer that, let’s discuss how PHP works. Because it is an […]

How to Install Wordpress on Ubuntu 12.04 LTS

Let’s be honest, sometimes we don’t necessarily want to start a site from scratch, especially a blog. There’s so many blogging platforms out there, why reinvent the wheel? Arguably the most well known, Wordpress, is very easy to install on Ubuntu 12.04 LTS. First things first, you will need to […]

How to Install the SQLite Module on Ubuntu 12.04 LTS

SQLite is a self-contained, serverless, zero-configuration, transactional SQL database engine. The SQLite website also boasts that it is the most widely deployed SQL database engine in the world. As I’ve previously discussed, SQLite has the advantage over MySQL as it can be used as an internal session handler with PHP. […]

How to Install the Memcached Module on Ubuntu 12.04 LTS

Installing the Memcached module for PHP on Ubuntu 12.04 LTS is as simple as can be. First let’s make sure we have Memcached installed: sudo apt-get install memcached On Ubuntu, the process to install the PHP module is similar to how we installed Memcached itself: sudo apt-get install php5-memcache php5-memcached […]

How to Setup a LEMP Stack on Ubuntu 12.04 LTS

Don’t get me wrong, there’s nothing wrong with a good ol’ LAMP stack (Linux, Apache, MySQL and PHP) but in my experience, Apache doesn’t necessarily scale all that well with PHP. It’s really not Apache’s fault, the fact is that most of the time servers are configured to use the […]

How to Setup a LAMP Stack on Ubuntu 12.04 LTS

It seemed fitting that the first post on PHP Avenue should be about setting up a new server with PHP. This particular post will focus on a traditional LAMP stack (Linux, Apache, MySQL, PHP) on Ubuntu 12.04 LTS. I also intend on writing additional posts covering the setup of a […]

Getting real IP addresses using NodeBalancer and Nginx

This one’s pretty simple, but it’s not documented by Linode and most of the sites I found on Google were people ranting about a lack of documentation but failing to provide their solution. The situation is this, I’m running sites behind a Linode NodeBalancer and I want the user’s real […]

PCI Compliance doesn't like the Desktop Services Store

The Desktop Services Store (DS_Store) as you probably already know, is a file that stores some metadata about the files in a directory in the OS X. I’ve taken a look at them, they seem pretty harmless, but in the realm of PCI Compliance they are a medium risk because […]

PCI Compliance and the importance of a 404 page

As you may remember from a previous post, I typically rewrite my error traffic back to / instead of having a fancy 404 page. The logic behind this is that I’d rather get my users to a page that’s functional instead of presenting them with an error page, also I’ve […]
