TokuDB MySQL Google Cloud

TokuDB Google Cloud Install: Starting MySQL… ERROR! The server quit without updating PID file

ErrorsLeave a comment

I am fairly new to TokuDB but so far I am impressed with the compression it provides to the data stored within. One of my clients has a ton of data that is constantly growing and thus TokuDB made a lot of sense for the solution that was created. While becoming more familiar with TokuDB and trying different cloud solutions I ran into a minor issue installing TokuDB on a Google Cloud VM instance but explain how to resolve easily below.

Ubuntu apt-get upgrade – The following packages have been kept back

InsightsLeave a comment

When upgrading packages on Ubuntu using the apt-get upgrade command you may notice that some packages are not upgraded. Ubuntu will not upgrade packages that could have a major impact to service on the server such as the kernel, kernel headers, MySQL packages, and various others. The packages are held back by aptitude as a safeguard to keep people from upgrading packages that might keep the server from rebooting or that might corrupt something like a database. Below we show the error in more detail and explain the command that can be run to upgrade the packages that are being held back.

Update WordPress Amazon Product in a Post Plugin 2.X to Amazon Product in a Post Plugin 3.X

InsightsLeave a comment

If you use the Amazon Product In A Post Plugin on WordPress you might have either not upgraded yet or decided to not upgrade because the shortcode syntax has changed. You can get around not upgrading by updating the WordPress post content immediately after you upgrade the Amazon Product In A Post Plugin. Below I describe the version that I upgraded and the MySQL syntax used to update the shortcode syntax to display Amazon products in WP posts.

MapPress WordPress Plugin – Change All Markers On A Single Map

Insights2 Comments

MapPress is a WordPress plugin that provides an interface to Google Maps and easily allows you to insert detailed Google Maps into WordPress posts or pages. We have a site that provides password auditing services called QD Tools and on the homepage there is a map that lists the city, state/province, and country of our customers. I have been using MapPress Pro for a long time because it offers lots of extra features and MapPress itself is such an awesome plugin I like supporting the developer. Anyhow the Google Map on the QD Tools homepage is has over 1,000 markers and continues to grow. I wanted to modify the default MapPress/Google Maps marker that was being used but there is no way in MapPress to retroactively change this so the instructions below explain how to do this.

SecurityLeave a comment

Need a quick way to generate a PHP backdoor for a compromised server you want to come back to later, then weevely is your application. I was pleasantly surprised when I started playing around with weevely in more detail as it provides a ton of built in functionality and does a lot more than I initially though that weevely did. The weevely application is built using Python and its current version on Backtrack 5 R3 is weevely v0.7. The weevley.py Python script is located in the /pentest/backdoors/web/weevely directory and some of its uses are described in more detail below.
