[Rev 4201] blank page when trying to install/update database schema
-
Hi,
I updated my Debian wheezy system via ‘apt-get update && apt-ger upgrade’. After that I also updated to the new subversion (4201) of fog.
When I run ‘./installfog.sh’ everything looks ok. But when I try to update the database schema via ‘http://172.30.40.25/fog/management’ I only see a blank page. I tried to skip the database update and finish the installation. But all i can see now when going to ‘http://172.30.40.25/fog’ or ‘http://172.30.40.25/fog/management’ is a blank page. Hard refreshing the page didn’t help.Debian GNU/Linux 7.9 (wheezy)
fog svn 4201Thanks for your help.

Can you try again and immediately after it blanks grab a copy of the error logs from Apache and post them here?

Just a contributor here:
We had a similar issue here after a trunk upgrade. The OP needs to check the Apache error log in (at least in the Redhat realm) /var/log/httpd/error_log
The OP can run the <…>/fog/management/ url to generate the blank page then immediately run this command from the linux console.
tail /var/log/httpd/error_log
That should show the OP the error that generated the blank page.

Hi i got this as well apache log

svn co https://svn.code.sf.net/p/freeghost/code/trunk /opt/fog_latest cd /opt/fog_latest/bin ./installfog.sh -
This is what I use.
sudo svn checkout https://svn.code.sf.net/p/freeghost/code/trunk -
I suppose this is as good a time as ever to recommend the troubleshooting script…

My error.log is 260M! I attached the end of the file.

And here the logfile of the troubleshooting script:

Could you please tell us which version of php is installed now?
dpkg -l | grep php(post the full output here)The syntax there looks pretty good to me (other foreach loops with reference just a few lines of code earlier seam to work?!?): http://sourceforge.net/p/freeghost/code/4201/tree/trunk/packages/web/lib/fog/FOGBase.class.php#l412

Could you please try checking out the newest SVN version and run the installer again?
-
Unfortunately that didn’t help. I now have Rev 4219.
-
AFAIK there should be a php version from another repo installed in current FOG trunk. php version 5.6.14… on my system. Do you see any errors while installfog.sh is running??
-
I installed the php version you have from the http://packages.dotdeb.org repo.

rc php5-mysql 5.4.39-0+deb7u2 ....Seams like you still have old stuff sitting there. ‘r’ means marked for remove and ‘c’ means config-files are still installed. Run
sudo apt-get purge php5-mysqlto make sure this is not getting in your way. Probably best to restart the server to make sure no one is using the old configs anymore.Are you still stuck with the database schema updater. Could you please check your apache error log again while accessing the web interface and running the schema updater.
-
I removed php5-mysql and restarted the server. But I still get the blang page. Yes, im still stuck at the database schema updater.
I attached my apache error log file (last 100 lines) while accessing the web interface.
error.log
I get this error every second. Even when i don’t access the webinterface. My current error.log file is 514M at the moment. The previous one is 787M. The ones before are arounc 1-15K. -
You see so many errors because your clients also access the web pages to get information. Error is a bit confusing as FOGCore.class.php does not even have 300 lines of code (http://sourceforge.net/p/freeghost/code/HEAD/tree/trunk/packages/web/lib/fog/FOGCore.class.php)!
PHP Fatal error: Call to a member function query() on null in /var/www/html/fog/lib/fog/FOGCore.class.php on line 310Maybe have a look at that file on your server and tell us what’s in line 310 or better try updating again. Are you sure you do checkout/update the full source code when running an update??
svn checkout https://svn.code.sf.net/p/freeghost/code/trunk cd trunk/bin sudo ./installfog.sh -
@Stefan-Kaegi Seams like I was wrong with the mysql package for debian. Please install php5-mysql (which will uninstall php5-mysqlnd instead) by
sudo apt-get install php5-mysqlI hope this will solve the ‘query() on null’ error for you!

I believe i figured out the issue, as well as the error you were seeing from FOGCore.
Query was null because the link was not connected due to the load issues we’ve been trying to fight lately
I believe I finally got to the bottom of it.
-
@Tom-Elliott Could be related to load but in this case I am fairly sure that
query() on nullis coming from mysqli class not being available. I just had that on one of my test debian systems when playing with the different php mysql packages. Seams likephp5-mysqlndfrom dotdeb is not properly configured to offer mysqli as it is used in FOG. Maybe it’s just a php.ini thing, I am not sure.
Exchanging php5-mysqlnd with php5-mysql solved that for me!
