I am trying to install the latest version of Moodle 3.6.3 on Amazon Linux 2 (on EC2)

I have the server up and running and have also setup a mySQL database via RDS and have also setup the moodledata folder.

I am trying to initiate the Moodle setup process via the browser and getting the following error message within the Chrome browser on both web and mobile:

Error Message:

"Moodle requires the xml PHP extension. Please install or enable the xml extension."

I have installed PHP7.2 on the instance along with a number of additional PHP packages, including PHP-XML. 

I would appreciate any assistance the community members might be able to provide to resolve this issue.

Thank in advance.

Have you restarted the web server service to pick up this additional PHP package? On a CentOS 7 server with Apache the command systemctl reload httpd should do this, if you're using Nginx or a different Linux distribution the command may be different.

Unfortunately no luck with restarting the server. I used the following commands

sudo su

service httpd stop

service httpd start

I used service httpd status to check the status.

Is there anyone else who is using PHP7.2 with Moodle 3.6.3? I am wondering if there might be any known compatibility issues.  Really at a loss otherwise...

Try stopping/starting your instance in the EC2 Dashboard

I also had the same issue on EC2 with Amazon Linux release 2 (Karoo) after installing 'php-xml.x86_64 7.2.16-1.amzn2.0.1'. Apache restart wouldn't do it.

But after I stopped my EC2 instance in the EC2 Dashboard and then started it again - I managed to get past this problem.
