Step 1: Install latest version of Varnish (3.0)

These first three lines are probably not required on Ubuntu 12.04 because the main repository already contains version 3, but you can use it anyhow. Older version of Ubuntu do need it though!

curl http://repo.varnish-cache.org/debian/GPG-key.txt | sudo apt-key add -
echo "deb http://repo.varnish-cache.org/ubuntu/ lucid varnish-3.0" | sudo tee -a /etc/apt/sources.list
sudo apt-get update

sudo apt-get install varnish

Step 2: Set backend server (Apache)

Edit the varnish configuration file.

sudo nano /etc/varnish/default.vcl

Set the backend server. The lines below say that the backend server (Apache) is available More >

Command “df” in linux shows incorrect free space after file removal

Today the “/tmp” directory was full on a server because of a huge log file. When I checked it with the command “df -h” is saw that the directory used 100% of disk space.

#Incremental     no
Incremental     yes

OpenPanel created apache log files per virtual host, so we don’t have to do that by ourselves. The access log files are located at “/var/log/apache2/openpanel/logs”.

To generate stats from an apache access log file, you’ll have to execute the following More >

In this post I’ll desribe how to configure POEdit for Zend Framework in Ubuntu. However POEdit is cross platform compatible and has the same GUI on Windows and Mac, so for these platforms you can also follow several steps below.

If you don’t have POEdit installed yet, open a terminal and execute:

apt-get install poedit

Now start the application with “Alt + F2″ and type “poeditor” and double click the icon. If you start POEdit for the first time, you’ll see the preferences dialog.

Append ” -L php” to the end of the “Parser command:” text field.
