Install critical components

At this point, you have a pretty nice server setup. Congrats! But, your server still doesn’t do anything useful. Let’s install some software.

Install a compiler

A compiler is often required to install Python packages and other software, so let’s just install one up-front.

sudo aptitude install build-essential

Install MySQL

Install MySQL:

sudo aptitude install mysql-server libmysqlclient-dev

Set root password when prompt asks you.

Verify that MySQL is running.

sudo netstat -tap | grep mysql

For connecting to MySQL, instead of the usual PHPMyAdmin, I now use Sequel Pro, a free app for Mac.

Improve MySQL security

Before using MySQL in production, you’ll want to improve your MySQL installation security. Run:

mysql_secure_installation

This will help you set a password for the root account, remove anonymous-user accounts, and remove the test database.

Keep your MySQL tables in tip-top shape

Over time your MySQL tables will get fragmented and queries will take longer to complete. You can keep your tables in top shape by regularly running OPTIMIZE TABLE on all your tables. But, since you’ll never remember to do this regularly, we should set up a cron job to do this.

Open up your crontab file:

crontab -e

Then, add the following line:

@weekly mysqlcheck -o --user=root --password=<your password here> -A

Also, you can try manually running the above command to verify that it works correctly.

Backup your MySQL databases

The excellent automysqlbackup utility can automatically make daily, weekly, and monthly backups of your MySQL database.

Install it:

sudo aptitude install automysqlbackup

Now, let’s configure it. Open the configuration file:

sudo nano /etc/default/automysqlbackup

By default, your database backups get stored in /var/lib/automysqlbackup which isn’t very intuitive. I recommend changing it to a folder within your home directory. To do this, find the line that begins with BACKUPDIR= and change it toBACKUPDIR="/home/<your username>/backups/"

You also want to get an email if an error occurs, so you’ll know if automatic backups stop working for some reason. Find the line that begins with MAILADDR= and change it to MAILADDR="<your email address>".

Close and save the file. That’s it!

Install Python

Install Python environment:

sudo aptitude install python-pip python-dev
sudo pip install virtualenv

This creates a global “pip” command to install Python packages. Don’t use it, because packages will be installed globally. Instead, use virtualenv.

Create a new virtualenv Python environment with:

virtualenv --distribute <environment_name>

Switch to the new environment with:

cd <environment_name>
source bin/activate

Note that the name of your environment is added to your command prompt.

Install Python packages with “pip” inside of virtualenv:

pip search <package_name>
pip install <package_name>

This is the best Python workflow that I’ve found. Let me know if you know of a better way to manage Python packages and Python installations.

Install Nginx

sudo aptitude install nginx

Install Apache

sudo aptitude install apache2

Install PHP5

sudo aptitude install php5 libapache2-mod-php5 php5-mysql
sudo service apache2 restart

Install Node.js

sudo aptitude update
sudo aptitude install python-software-properties python g++ make
sudo add-apt-repository ppa:chris-lea/node.js
sudo aptitude update
sudo aptitude install nodejs

Install MongoDB

Follow instructions on 10gen’s site: Install MongoDB on Ubuntu.

Install Redis

sudo aptitude install redis-server
At this point, you have a pretty nice server setup....
