Alternative PHP Cache (APC)

timmah1 · March 10, 2012

I have a dedicated server with GoDaddy.

I need to install Alternative PHP Cache (APC), but I do not know enough to do it myself, for fear of screwing the server up.

Can anybody show me a step-by-step tutorial on how to install it on my server?

Thanks in advance

Your in charge of a dedicated server yet don't know how to install packages? Sounds scary.

What distribution is the server running?

timmah1 · March 11, 2012

CENTOS 5.6 i686 virtuozzo

eww. I don't think contos has a package for that. You'll need to install it via pear.

Something like:

Make sure you have pear and any dependencies installed.

sudo yum install php-pear
sudo yum install php-devel
sudo yum install httpd-devel

Install apc

sudo pecl install apc

Add the extension to php's configuration

echo "extension=apc.so" | sudo tee -a /etc/php.d/apc.ini

Restart apache

sudo /etc/init.d/httpd start

You might want to do a google search for a guide but that should pretty much cover it.

I appreciate your help Thorpe.

I am just a newbie with servers, and I'm sure I'll be back here for some help, but I really do appreciate all the help you have given me

Thanks again

Thorpe,

I know this is an older thread, but I'm still trying to install APC on the server, and I'm getting errors.

Here is everything
