MySQL Post Install Setup

After MySQL is installed, either as part of Ubuntu Server installation sequence or separately through an appropriate apt-get command, it needs to be properly initialized for use by a client. One key concept of any standalone database engine is that they have their own user namespace and associated access rights. MySQL is no different and therefore this needs to be appropriately setup before any client can create/update/delete entries into any table. Essentially this involves the following steps, all to be undertaken as the Administrator (or the root account, by default):

Linux Command Output Redirection Rules

Here's another thing that I learned today -- command output redirection syntax. > redirects the program's output to the specified file which is specified afterwards. If > is preceded by ampersand, shell redirects all outputs (error and normal) to the file right of > . If you don't specify ampersand, then only normal output is redirected. In other words: command &> file # redirect error and standard output to file command > file # redirect standard output to file command 2> file # redirect error output to file This is how things work on Ubuntu and bash. Other shells could very well be different.

VirtualBox - Sharing a host folder on Ubuntu guest

I have been using VirtualBox to run Ubuntu Server on my Windows PC over the last couple of weeks. The more time I spend with it, the more I find the need to get myself acclimatized with the good old command line method to interact with your OS. Though I'm a pretty fast learner and have spent quite a bit of time on Linux and its variants in the past, the sheer number of commands that one has to learn to manage the large array of interfaces in present-day OS is astounding. For example, I wanted to share a folder from my Windows host to the Ubuntu guest. How do I go about doing it? How do I mount a USB stick on guest OS? Luckily, answers to most of these questions are only a few clicks away with the help of Google. However, since I expect to carry out some of these tasks quite often in the future, I'm going to try and record things that I discover and re-learn in various blog posts, so as to act as a reference for myself. This post talks about how to go about accessing a Host

Setting up Ubuntu for Python Development

This is more for my own reference as I often forget the various steps that I followed to get an environment set up. This post lists the steps that I followed to setup an Ubuntu Server for Python/Django/MySQL environment. The steps are drawn from various resources on the web -- official documentation from Ubuntu, some blog posts and a few pointers on stackexchange/stackoverflow. All credits due to all the kind souls who shared knowledge.
