Centos – Installing GD Library on Centos 6.7 and PHP 5.4

Your custom-compiled PHP should have installed pecl, and configured it properly.

Have you tried running "pecl install apc"?

If your system is not finding pecl, it's probable that you used some funny --prefix when you ./configure'd PHP.

For instance, if you compiled php like this:

$ ./configure --prefix=/foo
$ make
# make install

then you'll either want to get /foo/bin into $PATH, or you could just run

$ /foo/bin/pecl install apc

EDIT: Now I remember: try pecl install apc-beta. Something is screwy with 5.3.3 and non-beta APC. My experience is apc-beta works fine.

You can compile and install manually only the mcrypt extension. This is what I did in my CentOS 5.6 VPS:

First install some required packages:

yum install php53-devel libmcrypt-devel gcc gcc-c++

Then download the php 5.3.6 source code from php.net and unpack it:

wget http://mx2.php.net/get/php-5.3.6.tar.bz2/from/us3.php.net/mirror
tar xvjf php-5.3.6.tar.bz2

(Please note that the download link will change with every subsequent PHP release.)

Go to the directory with the mcrypt extension source code and compile:

cd php-5.3.6/ext/mcrypt/
phpize
aclocal
./configure
make

Then install:

make install

Create the configuration file for PHP /etc/php.d/mcrypt.ini containing:

extension=mcrypt.so

Restart apache:

/etc/init.d/httpd restart

Create a file with phpinfo just to check if the extension was loaded:

<?php
phpinfo();
?>
