Now "Close" and "Reload" and you can install the php5-apc package.

The version of APC that ships with 10.4 and 10.10 causes problems.  You'll need to downgrade it for it to work.  When it asks if you want to use the spin locks type in yes.  Run the following commands in a terminal:

sudo apt-get remove apc-php
sudo apt-get remove php-apc
sudo pecl config-set preferred_state beta

sudo pecl install APC-3.1.5
sudo pecl config-set preferred_state stable
sudo pecl config-set preferred_state stable

</source>
You may also want to try the steps for Meerkat (below)


If you get errors about missing phpize then you need to install php5-dev by:
===For Meerkat (10.10)===
<source lang="bash">
This seems to work as of Dec 20, 2010.
sudo apt-get install php5-dev
</source>
If you get errors about apxs then you need to install the apache development package:
<source lang="bash">
<source lang="bash">
sudo apt-get install apache2-prefork-dev
sudo apt-get remove php-apc
sudo pecl install APC
</source>
</source>

apc.write_lock=1
apc.write_lock=1
apc-slam_defense=0
apc.slam_defense=0
</source>
 
==Sessions==
Now you need to set the session save path.  The default is /tmp but that is causing problems and the script to clean up sessions doesn't look there.  You'll need to edit the files for apache and cli and make the same change.  To edit the apache php config type:
<source lang="bash">
sudo gedit /etc/php5/apache2/php.ini
</source>
</source>
Find the line that looks like:
<source lang="ini">
;session.save_path = "/tmp"
</source>
And change it to be (don't forget to remove the semi-colon):
<source lang="ini">
session.save_path = "/var/lib/php5"
</source>
Now edit the cli config file and make the same change:
<source lang="bash">
sudo gedit /etc/php5/cli/php.ini
</source>
==Overloaded Functions==
Until the code can be updated, you'll need to change a few functions in one file.  If you're using the 4.0.4 or before you'll need to make this change.  The development code and any future releases won't need this change.  You'll need to edit your I2CE_Form.php file which is under I2CE/modules/Forms/lib depending on where you installed I2CE.
The functions __get, __set, __isset and __unset need to be changed from protected to public.  For example:
<source lang="php">
protected function __get( $key ) {
</source>
Should now be:
<source lang="php">
public function __get( $key ) {
</source>
You should make this change for all the functions listed above.


==Restart==

Ubuntu 10.4 and 10.10 come with PHP 5.3 so there a few a few issues that need to be corrected.

SEE: http://pecl.php.net/bugs/bug.php?id=16814 for a discussion of the issue. It is not clear what the correct resolution is, but we try to offer some suggestions here.

Do I Have The Problem?

Simple Install

Command Line

<source lang='bash'> sudo add-apt-repository ppa:chris-lea/php-pecl-extras sudo apt-get update sudo apt-get install php5-apc </source>

GUI

Go to "System"->"Administration"->"Synaptic Package Manager"->"Settings"->"Repositories"->"Other Software"->"Add..."

  • Add the following APT Line For Maverick Meerkat (10.10) :
deb http://ppa.launchpad.net/chris-lea/php-pecl-extras/ubuntu maverick main
  • Add the following APT Line For For Lucid Lynx (10.04)
deb http://ppa.launchpad.net/chris-lea/php-pecl-extras/ubuntu lucid main

Now "Close" and "Reload" and you can install the php5-apc package.

Manual Install

To compile pecl packages yourself you'll need these packages installed. They may already be installed. <source lang="bash"> sudo apt-get install php5-dev apache2-prefork-dev </source>

The version of APC that ships with 10.4 and 10.10 causes problems. You'll need to downgrade it for it to work. When it asks if you want to use the spin locks type in yes. Run the following commands in a terminal:

For Lucid (10.04)

<source lang="bash"> sudo apt-get remove php-apc sudo pecl config-set preferred_state beta sudo pecl install APC-3.1.5 sudo pecl config-set preferred_state stable </source> You may also want to try the steps for Meerkat (below)

For Meerkat (10.10)

This seems to work as of Dec 20, 2010. <source lang="bash"> sudo apt-get remove php-apc sudo pecl install APC </source>

Now you need to set the configuration options for APC. Create or edit the ini file by typing: <source lang="bash"> sudo gedit /etc/php5/conf.d/apc.ini </source>

The contents should be: <source lang="ini"> extension=apc.so apc.shm_size=100M apc.write_lock=1 apc.slam_defense=0 </source>

Restart

Now restart apache and memcached (if you're using it) and try to access your site again. <source lang="bash"> sudo /etc/init.d/apache2 restart sudo /etc/init.d/memcached restart </source>
