Changing Plesk Fast CGI to Apache PHP with ZF

So recently I’ve had to change the php mode from Fast CGI to Apache Module in plesk due to the http authenticate functions in php not working. This caused my Zend Framework website to produce a 500 error, in my case it was something to do with:

Fatal error: Uncaught exception 'Zend_Session_Exception' with message 'session has already been started by session.auto-start or session_start()

The reason for the error is that the session already existed from my first visit and CGI was the owner, when I changed it to Apache module apache did not have permission to change the session data. The solution, shut down your browser (or start a privacy mode) and then try and view your website. Everything should work fine afterwards.

How to Enable SSL on Xampp with Vhosts

If you need to enable SSL on Xampp whilst stilling using vhosts, follow the next few steps. It assumes that you already have vhosts enabled.

Open xampp/apache/conf/extra/httpd-vhosts.conf
Around line 19 you should see “NameVirtualHost *:80″, below this line add “NameVirtualHost *:443″ (without quotes)

Then add a new vhost site just like a normal one but with *443 instead on *80 and the following lines:

SSLEngine on
SSLCertificateFile conf/ssl.crt/server.crt
SSLCertificateKeyFile conf/ssl.key/server.key

An example of this is:

    DocumentRoot "C:/xampp/htdocs/myproject/public"
    ServerName mysite.local
    ServerAlias mysite.local
	SSLEngine on
	SSLCertificateFile conf/ssl.crt/server.crt
	SSLCertificateKeyFile conf/ssl.key/server.key

Restart Xampp apache and everything should work fine.

Installing LAMP on Ubuntu

So I been getting rather annoyed with CentOs recently, mainly due to the lack of PHP support above 5.1.6, especially with all the cool features of 5.3. Also I always seem to have massive trouble installing anything like Mcypt or Memcache.

So I thought I’d give Ubuntu a go and I’m now a convert! Everything went smoothly, not one issue or problem. The support forums are brilliant and almost all questions have already been answered. I dont know whether I’ve just got lucky (I guess only time will tell) but Ubuntu is now my first port of call when setting up a new server.

Below is a line by line tutorial on how I got setup with Ubuntu 10.04 Lucid. I don’t go into too much details on how to edit the files using nano or vi but you can have a look on my previous posts or online, otherwise you can sftp in using root and change the files that way, (my preferred method).

Install Lamp on Ubuntu

sudo tasksel install lamp-server
You will need to enter a root mysql password for mysql

Enable mod_rewrite in xampp

For some reason my install of XAMPP didn’t have mod_rewrite automatically enabled? Not really sure why  but basically below are the instructions on how to enable .htaccess mod_rewrite in xampp.

1. Go to the directory of installation <C:\xampp>\apache\conf

2. Open and edit httpd.conf in a text editor

3. Find the line which contains

#LoadModule rewrite_module modules/mod_rewrite.so

and (uncomment) change to

LoadModule rewrite_module modules/mod_rewrite.so

4. Find all occurrences of

AllowOverride None

and change to

AllowOverride All

I think it appears 2 or 3 times on the configuration file.

5. Restart xampp

That’s it you should be good to go.
