Installing PHP APC on GNU/Linux Centos 5

Do to so, we execute the following command:

yum install php-pear

But, this will not run on its own, we need the following package for the phpizecommand:

yum install php-devel

We also need the apxs command, which is installed via the following package:

yum install httpd-devel

Now we have all the software we need, so we install apc via the pecl command:

pecl install apc 

Once that finishes, we need to enable apc in Apache's configuration. the following command should do this for us.

echo "extension=apc.so" > /etc/php.d/apc.ini

Then we restart Apache:

/etc/init.d/httpd restart
