Run this in the folder where you want the files dumped:
for I in $(mysql -uroot -p -e 'show databases' -s --skip-column-names); do mysqldump $I > "$I.sql"; done
List all packages
dpkg --list

Start with a base Ubuntu 14.04 install, and then run:
curl -sL rt.cx/ee | sudo bash # install easy-engine source /etc/bash_completion.d/ee # code completion in CLI apt-get install memcached php5-memcached # install memcached and memcached php bridge (optionally also install php5-memcache) ee system install # install nginx, php, mysql, postfix ee site create example.com --wp # install wordpress on example.com
That’s really all you need to do!

For stopping machines properly, you need to isntall apcid on the guest machines.
Here’s a quick way to convert SVG to PNG with transparent background
convert -background none image.svg image.png
Adjust size
If you want to scale the image to a larger size without antialiasing (which makes the image look fuzzy), you can add the density parameter, like this:
convert -density 200 -background none image.svg image.png
Simply increase the density value to increase the image size.
To install ImageMagick on OS X with Homebrew:
brew install imagemagick
For Ubuntu:
sudo apt-get install imagemagick
To show the output from all log files in a directory, run:
tail -f *.log
Output example:
==> log1 <== 1.2.3.4 - - [16/Nov/2014:03:31:06 +0000] "GET /robots.txt HTTP/1.1" 200 107 1.2.3.4 - - [16/Nov/2014:03:31:07 +0000] "GET / HTTP/1.1" 200 7777 1.2.3.4 - - [16/Nov/2014:03:36:05 +0000] "GET /robots.txt HTTP/1.1" 200 107 ==> log2 <== 1.2.3.4 - - [16/Nov/2014:05:39:36 +0000] "GET / HTTP/1.1" 200 34569 1.2.3.4 - - [16/Nov/2014:05:40:44 +0000] "POST /wp-admin/ HTTP/1.0" 200 961 1.2.3.4 - - [16/Nov/2014:05:40:57 +0000] "POST /wp-admin/ HTTP/1.0" 200 50505
Start out with the basics – Apache, MySQL and PHP + extensions
apt-get install mysql-server mysql-client apache2 php5 php5-cli libapache2-mod-php5 php5-mysql php5-curl php5-gd php-pear php5-imagick php5-mcrypt php5-memcache php5-mhash php5-sqlite php5-xmlrpc php5-xsl php5-json php5-dev libpcre3-dev
I recommend using this on Debian Jessie. That way you get a bleeding edge version of PHP (5.5.8 as of right now)
OpCode cache and APCu (Optional)
pecl install ZendOpcache-beta pecl install apcu-beta
Add the following to /etc/php5/apache2/php.ini
zend_extension=opcache.so extension=apcu.so
Configure Opcache by adding this to /etc/php5/apache2/php.ini
opcache.max_accelerated_files=30000 opcache.memory_consumption=160 opcache.revalidate_freq=0
Restart apache. The extensions should be available and configured. (You can verify this via phpinfo(); )
Useful tools (Optional)
apt-get install htop vim
Raspberry pi runs Debian Wheezy, but with just one quick line change we can upgrade to Debian Jessie which is a newer version and provides PHP 5.5 binaries (5.5.8 at the time of this blog post.)
Start out by editing the APT sources:
vim /etc/apt/sources.list
Change wheezy to jessie, so that it looks like this:
deb http://mirrordirector.raspbian.org/raspbian/ jessie main contrib non-free rpi
(Don’t add or remove any lines, just change the one above)
Now run:
apt-get update && apt-get upgrade && apt-get autoremove
If you havent aready installed PHP, you can do it now via:
apt-get install php5 php5-cli
Finally, confirm your PHP version:
php -v
This should result in:
