Fog 1.5.7 on centos 8.0

[lebrun78]

Hello
We bought a nice new server for FOG.
I’m trying to install fog on a Centos 8.0
I get no error running the installation script, but when I am at

This can be done by opening a web browser and going to:

   http://192.168.122.12/fog/management

I get a blank screen on my navigator

In the /var/log/httpd/access_log I have:

192.168.122.1 - - [29/Oct/2019:13:42:07 -0400] "GET /fog/management/ HTTP/1.1" 500 - "-" "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:70.0) Gecko/20100101 Firefox/70.0"

In the /var/log/php-fpm/www-error.log I have

Insert [29-Oct-2019 17:32:31 UTC] PHP Fatal error:  Uncaught Error: Call to undefined function json_encode() in /var/www/html/fog/lib/db/pdodb.class.php:427

Did you restart the PHP-FPM and Apache service after you installed that package? Just restart the whole server to make sure.

@lebrun78 I have not had the time to setup a new CentOS 8 machine yet. Will do so and give it a try myself.

@lebrun78 Just tested on a fresh clean CentOS 8 install. No problem!

My guess is you have manually added some extern PHP repo before running the FOG installer. CentOS 8 comes with PHP version 7.2(.11) and so it’s not needed to use external repos.

Please run rpm -qa | grep php and post the result here.

P.S.: The only thing I had an issue with is the firewall. Seems like our firewall detection in the scripts is failing here and so I didn’t notice that at first.
