problem with GD image extension on Amazon Linux 2

Question

I've recently created LAMP servers on EC2 instances using Amazon Linux AMI.

using

sudo yum install -y php70-gd

I installed the GD extension. This all worked fine and i could upload and manipulate images using PHP.

Now I've created a LAMP server using Amazon Linux 2 using the tutorial here :https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-lamp-amazon-linux-2.html

My problem is that I can't get the GD extension to work. i tried using

sudo yum install -y gd

and this seemed to install an older version of GD. I tried

sudo yum install php-gd

and this seems to install the latest version of the extension.

But the gd extension still doesn't seem to work. when I enter yum info gd In the console it shows :

Loaded plugins: extras_suggestions, langpacks, priorities, update-motd
Installed Packages

Arch        : x86_64

Description : The php-gd package contains a dynamic shared object that will add
            : support for using the gd graphics library to PHP.

when I try an image resize script I get an error. I've tried this test script :

$testGD = get_extension_funcs("gd"); // Grab function list 
if (!$testGD){ echo "GD not installed."; exit; }
echo"<pre>".print_r($testGD,true)."</pre>";

and this gives me the result

GD not installed.

so obviously something is not right. Can anyone help?

thanks

Answer 1

$ sudo yum install -y php-gd
$ sudo systemctl restart php-fpm

No need to reboot

Answer 2

Amazon Linux 2 uses Apache with PHP-FPM instead of mod_php. So you need to restart the php-fpm process to reload PHP with the new extension.

sudo systemctl restart php-fpm

Answer 3

I'm running php 7.2.14 on Amazon Linux 2 and this worked for me:

$ sudo yum update -y
$ sudo yum install -y php-gd
$ sudo reboot

Answer 4

And solved... Turns out restarting apache with

sudo systemctl restart httpd

wasn't enough to load the newly installed component...

what i needed to do was

sudo reboot

and everything works...

Why did't i try that 24 hours ago!

Answer 5

my PHP version was - PHP 7.2.18 $ php -v

I had to install -y php72-gd

$ sudo yum update -y $ sudo yum install -y php72-gd $ sudo reboot
