HowTo install ZendDebugger for PHP 5.4 or PHP 5.5 on Debian

Since the ZendDebugger is bundled with ZendStudio and ZendServer the PHP module cannot easily be downloaded standalone.

But with some simple steps the module can be extracted out of the official ZendStudio tarball which can be downloaded for free on


Make sure, openssl0.9.8 is installed. Newer Versions like openssl1.0.0+ will not work.

on debian squeeze

$ sudo apt-get install libssl0.9.8

on debian wheezy

$ wget
$ sudo dpkg -i libssl0.9.8_0.9.8o-7_amd64.deb

Extract the extension

Create a temporary working dir

$ mkdir /tmp/zend_debugger
$ cd /tmp/zend_debugger

Download Zend Studio 10.6

$ wget

Find the extension in the archive

$ tar -tvf ZendStudio-10.6.0-linux.gtk.x86_64.tar.gz | grep
This will give you the following output:
-rwxrwxr-x vagrant/nogroup   238153 2014-01-08 16:11 ZendStudio/plugins/com.zend.php.debug.debugger.linux.x86_64_10.6.0.v20140128-2127/resources/php53/
-rwxrwxr-x vagrant/nogroup   238217 2014-01-08 15:56 ZendStudio/plugins/com.zend.php.debug.debugger.linux.x86_64_10.6.0.v20140128-2127/resources/php54/
-rw-r--r-- vagrant/nogroup   238631 2014-01-08 15:22 ZendStudio/plugins/com.zend.php.debug.debugger.linux.x86_64_10.6.0.v20140128-2127/resources/php55/

Extract the extension for PHP 5.3, 5.4 and 5.5

$ tar -xzvf ZendStudio-10.6.0-linux.gtk.x86_64.tar.gz --strip-components 4 --wildcards *

Install the extension

Now copy the extension matching your PHP Version to the local extension dir

For PHP 5.5

$ sudo cp php55/ `php -i | grep extension_dir | awk '{print $NF}'`

For PHP 5.4

sudo cp php54/ `php -i | grep extension_dir | awk '{print $NF}'`

Update your php.ini

Add the following lines at the end of your php.ini file
[Zend Debugger]

Check the extension

$ php -v
PHP 5.5.11-1~dotdeb.1 (cli) (built: Apr  4 2014 02:15:16)

    with Zend Debugger v6.0.0, Copyright (c) 1999-2013, by Zend Technologies

That's it. If you can find the line "Zend Debugger v6.0.0" in the output the debugger extension is successfully installed.

This error happens even with the latest nodejs version if you're using a ssl certificate whose domain cannot be resolved by your dns.

Let's say your SSL certificate is issued to make sure a dns lookup can resolve this domain.

Simply add your domain to your /etc/hosts file

If your using a wildcard certificate * you can simply add this domain to your /etc/hosts file: *

This error happens under IE 10, if nodejs and you webpage runs on a different port. You should ensure that your webserver and your nodejs server are running on the same port with the same protocol.
