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 http://www.zend.com/en/products/studio/downloads.

Prerequisites

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 http://snapshot.debian.org/archive/debian/20110406T213352Z/pool/main/o/openssl098/libssl0.9.8_0.9.8o-7_amd64.deb
$ 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 http://downloads.zend.com/studio-eclipse/10.6.0/ZendStudio-10.6.0-linux.gtk.x86_64.tar.gz

Find the extension in the archive

$ tar -tvf ZendStudio-10.6.0-linux.gtk.x86_64.tar.gz | grep ZendDebugger.so

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/ZendDebugger.so
-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/ZendDebugger.so
-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/ZendDebugger.so

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 *ZendDebugger.so

Install the extension

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

For PHP 5.5

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

For PHP 5.4

sudo cp php54/ZendDebugger.so `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]
zend_extension=ZendDebugger.so
zend_debugger.allow_hosts=127.0.0.1/24,192.0.0.1/32
zend_debugger.expose_remotely=allowed_hosts

Check the extension

$ php -v

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

NodeJs socket hang up

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 www.your-domain.com make sure a dns lookup can resolve this domain.

Simply add your domain to your /etc/hosts file
127.0.0.1 www.your-domain.com

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

127.0.0.1 *.your-domain.com

socket.io.js, line 1641 character 7 Access denied

SCRIPT5: Access is denied.

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.
