@dsoden You seem to be a bit disappointed, which I understand as things don’t work as expected. But see, this is a community driven open source software and we work hard to try and make things work as well as help people solve problems.

CentOS 8 was released 5-6 weeks ago and I am aware we are behind. But as long as people don’t ask about it we usually don’t find the time to adjust the installer to meet new OS versions beforehand.

As you see in this topic I have tried to replicate an issue reported by another using related to PHP but I couldn’t! The install simply worked for me, no problem.

Not saying that the installer is perfect but please be patient and help us find and fix this. First I may ask you to use the latest developer source and try with that:

sudo -i
git clone https://github.com/FOGProject/fogproject/
cd fogproject/bin
./installfog.sh

By the way, that network interface selection BUG should be fixed in the developers version already.

@dsoden On your centos 8 install why is the virtual bridge 0 installed? While I’m sure there are other issues with the install, if you could hide that adapter from the installer, I fell you should get past this error.

[dsoden]

@george1421 no clue, I did not install it and virturalbox only assigned one. I assume CentOS detected something on the base install and added it. Not even sure if this is an issue. I see @Sebastian-Roth reply too and apparently there is a bug in the IO selection. using nmcli I downed and deleted.

[dsoden]

@Sebastian-Roth I appreciate the community and open-source in general. Been using community driven products like CentOS and webmin/virtualmin for many years now. I’ve also come to expect a certain level of reliability in using them. not being able to install a product is usually a bad sign that things are not stable. Open source products work for folks when they work. I don’t want to debate or questions ones or a teams commitment or even diminish efforts, for that I am grateful. There is however a sense of reality in that one cant use and count on something if unstable. I get your all are now working on it. May I please make a valid suggestion based on the observation of a newcomer? Great thanks, perhaps say here… that Debin is (Recommended). I see 99% of most youtube videos on this app all using Debian and look at your own signature bloc where you say… Web GUI issue? Please check apache error (debian/ubuntu: /var/log/apache2/error.log, centos/fedora/rhel: /var/log/httpd/error_log) and php-fpm log (/var/log/php*-fpm.log) an there is no mention of CentOS. This confirms this community is in favor of Debian - which is totally fine. It sets expectations that Debian takes priority as its where most folks are at - hell I’d do the same too. My point here is I would not have spent so much time fighting something that is likely a bug and report it much sooner.

Ill try the latest developer source. I don’t mind helping with testing at all and would be happy to. just trying to wrap my head around all of if. Plus I’m not a Linux admin normally - windows yes - for the record even with this bug herein ANYTHING has to be better than windows 10 stability. More and more I’m turning to Linux these days.

@dsoden Please re-read what you write…

Just wrong!

Not my problem.

[dsoden]

@dsoden I just happen to see your mention of cent in the signature bock I saw debian/unbuntu: and stopped reading as I thought the rest was code for that platform. facepalm my bad… Debian is however IMO the most accepted and preferable platform for this system

[dsoden]

@Sebastian-Roth wow - calm down man… apparently your one of those hyper sensitive folks with a massive ego made of glass! Your right its not your problem, it’s mine.

one of the questions installer askes if you want to change host name - I said YES
changed to fogserver.local
never took…

@dsoden @Sebastian-Roth @george1421

Please provide the error log from : /var/log/php-fpm/www-error.log

This will provide the error causing your White Screen.

The issue with CentOS 8 is being addressed, but we need information.

You’re right that opensource works when it works, and believe me, we want to help and get this fixed.

Changing the hostname, for fog, does not change the hostname for the machine. This is more related to updating the SSL certificates based on the DNS Server.

The installer tries to do everything it can for you, but there are areas we try not to change, such as the physical machine hostname as there could be any number of reasons this is setup as such.

Can you explain how it’s things are worse?

I want to help, and I’m 100% sure we can get this fixed and running for you. I just need information to be able to do that. I actually have a CentOS 8 server running for testing at work.

No amount of bickering, backtalk, or anything (from anyone) is going to help that.

worse because I assumed the question about changing the hostname… well changed the hostname of the system and app somehow, odd question if one does not have the context you provided above. That makes sense. Also I had not used that question till the last install round (like on #10 now) and when I did not see it work I figured more bugs.

@dsoden Please run: dnf -y install php-json

install php-json

I did a standard install and found a few things in the install script. I got to installing the schema and got the white screen of the OP. I went and check php-fpm error log and found the same error as the OP.

Installing php-json pushed the install forward. Then went back to web ui and installed the schema and the following error was thrown in the web ui.

[Tom Elliott]

@george1421 Can you run from MYSQL root user:

SHOW GRANTS FOR fogstorage;

[Tom Elliott]

@george1421 And this is from Master branch I take it? As this is what shows up, now, for the dev-branch and working-1.6

"DELETE FROM mysql.user WHERE user='$fogstoragenodeuser'",
"CREATE USER '$fogstoragenodeuser'@'%' IDENTIFIED BY '$fogstoragenodepass'",
"GRANT ALL PRIVILEGES ON `" . DATABASE_NAME . "`.* TO '$fogstoragenodeuser'@'%'",

Master is not as far forward as dev-branch is.

[george1421]

@Tom-Elliott I’m still pecking at it. But this is what I know so far.
This is failing

GRANT USAGE ON 'fog'.* TO 'fogstorage'@'%' IDENTIFIED BY 'fs55548845957';

But I can get the same results with.

create user 'fogstorage'@'%' IDENTIFIED BY 'fs55548845957';
grant all on fog.* to 'fogstorage'@'%';

It was throwing an error on the grant all with single quotes around fog in fog.*

[Tom Elliott]

@george1421 Probably need to delete the user entirely.

[george1421]

@Tom-Elliott I switched to working is that not the right one?

[Tom Elliott]

@george1421 working-1.6 or dev-branch are the branches you should be on. I don’t think we have a branch named just working anymore.
