I loaded the LAMP appliance and went to http://[serverIP]/phpinfo.php

The PHP info page states this:

Zend Engine: 220060519

This program makes use of the Zend Scripting Language Engine:
Zend Engine v2.2.0, Copyright (c) 1998-2007 Zend Technologies

It is not the version you are looking for, but I hope that helps.

I have compiled PHP with Zend before, it is not bad.  I have never tried doing an upgrade of Zend so I am sure you are right, it would probably not be nice.

Maybe the best thing is to start from the core appliance and add from there.

apt-get install php5-xcache

Is a patch needed to include xcache in LAMP? If so, I've taken the first steps. What I wonder is whether xcache-admin should be available from the usage.txt/confconsole. First draft with simple install of xcache is available as an attachment here: http://wiki.turnkeylinux.org/Whiteboard/PHP_acceleration. I need to do additional work if the web-based xcache administration page is to be available. Give the word, and I or we will proceed.

I've finished an XCache patch for TKL's LAMP stack. I'm going to try to post it as an attachment over here: http://wiki.turnkeylinux.org/Whiteboard/PHP_acceleration

Credentials for LAMP are the same as the existing stack.

Credentials for XCache-Admin page: username: admin, Password: admin

Any feedback would be appreciated. Saw this was a high priority blueprint. Hope someone can still make use of it.

Bottom line, since there seems to be significant community interest in this we'll enable xcache in the upcoming beta Lucid builds. If there are issues with acceleration we should be able to catch them on a per-appliance basis, with the help of the community of course.

I forgot to post the build notes for the appliance. Without the admin interface, XCache is as easy as: apt-get install php5-cache on with the LAMP appliance.

With the XCache admin interface, build notes are something like this:

XCache + LAMP Build Notes

Download TKL LAMP VMs.

Import LAMP appliance with VirtualBox

Leave hostname alone.

apt-get install php5-xcache

/etc/init.d/apache2 restart

cd /etc/apache2/sites-available

cp default xcache

In xcache, set path to /usr/share/xcache/admin

nano xcache

Configure Apache2

cd /etc/apache2/

Instruct Ampache to listen on port 12323

nano ports.conf

a2ensite xcache

Edit /etc/php5/apache2/php.ini:

nano /etc/php5/apache2/php.ini

Append the following two lines to php.ini to set username "admin" and password "admin"

xcache.admin.user = "admin"
xcache.admin.pass = "21232f297a57a5a743894a0e4a801fc3"

Set permissions

chmod 755 /usr/share/xcache/admin

chown www-data /usr/share/xcache/admin

Restart Apache2

/etc/init.d/apache2 restart

It's my understanding that the LAMP and LAPP 11.0 releases have xcache built in; hopefully that answers the question. Feel like it might.

RE Xcache:  The perpetual quest to get Magento to show some moderate speed.  When I "apt-get install php5-xcache" on Magento appliance I am told the system is already to the current build.

However, I can't find that Magento sees any Caching going on.

When I search for php.ini in the sytem I find:

etc/php5/cli/php.ini

etc/php5/apache2/php.ini

var/www/magento/php.ini

Magento version is a very short list that seems to be there for Cpanel type installations.

I have been looking around for how to optimize and test Xcache.. this one references how to install and optimize on a Cpanel type server: 

http://www.thewebhostinghero.com/tutorials/xcache-w3tc-on-a-cpanel-serve...

But this is not a CPanel type server, I know.

This link talks about installing/working with memcached or apc on a Magento Server, and specifying the Cache Type in app/etc/local.xml

http://magebase.com/magento-tutorials/speeding-up-magento-with-apc-or-me...

My local XML does not have a reference to Xcache (or other caches).  Neither do any of my php.ini files that I can find.

So,  should I trust that XCache is working and simply reference Xcache in my local.xml (as apc is being referenced)?  I have tried in the past to get APC to work instead but from what I can see the system will only work with Xcache OR APC and I was never able to remove Xcache (some other posts here follow this quest).

Thoughts on how to proceed?  Thanks to all!

The reference to setting up cache in Magento  via local.xml.additional had a simple statement to add: 

If you look at: app/etc/local.xml.additional, you will notice that there is a <cache>element that allows you to specify which caching method you are using in the <backend>element. This can have one of the following values:

• apc
• memcached
• xcache

We are dealing with APC here so we’ll just add:

1 2 3 4 5 6 7 8

<global> ...     <cache>         <backend>apc</backend>         <prefix>MAGE_</prefix>     </cache> ... </global>

 

However, The TTK local.xml.additional has the following in it saying, to Move the Appropriate code into local.xml.  This is the reference that refers to xcache...(apc/memcached/xcache)..  and I am somewhat stumped as to any control to add to this and/or what I am actually looking at...
