Apache Error on Trunk 4991

Kris Phillips

I just upgraded one of my servers from 1.2 to Trunk SVN version 4990 and am getting an error during the install.

My install gets to the point of backing up the MySQL database during the install and then says the following:

Setting up SSL FOG Server…OK
Restarting Apache2 for fog vhost…OK
Changing permissions on apache log files…OK
Backing up database…Failed!

Upon checking the httpd logs in /var/logs/httpd, its stating the following when I try to pull open the fog UI on the web interface:

[Fri Mar 11 11:12:19.144405 2016] [:error] [pid 5353] [client 10.10.51.22:33617] PHP Fatal error: Cannot create references to elements of a temporary array expression in /var/www/html/fog/lib/fog/fogcore.class.php on line 120

Is something broken on the current trunk that is causing this?

Is your fog server behind an internet proxy server?

Kris Phillips

There is a HTTP and HTTPS filter that filters traffic in line on a firewall out to the internet, but nothing for local access. How would that have anything to do with a MariaDB backup, though?

Sebastian Roth

I am sure Tom will take care of this in a minute… Sounds like a code issue.

@Kris-Phillips Well if you have the environment variables set to use an external proxy server for internet access, that would confuse the db backup function (which uses wget) to clone the backup. I have personally experienced this before. If you have the environment variables set you need to tell them to not use the proxy for the local machine.

Kris Phillips

Awesome. Thank you. Will it be in the next commit to the SVN? Because I’ll just watch for the version number to bump one.

Tom Elliott

There is no coding issue. It’s definitely related to the Proxy system. Just add --no_proxy=localhost,<ipoffogserver> or something similar to that.

george1421

@Kris-Phillips Just to add a little background info to this.

at the linux command prompt on your FOG server key in the following command.

set | grep proxy

If you get something like this, you have a proxy server configuration.

http_proxy=https://192.168.1.48:3128
https_proxy=http://192.168.1.48:3128
no_proxy=192.168.1.53

The key thing you need to add is the last line with the no proxy set to the IP address of your fog server.

Kris Phillips

I ran set | grep proxy and it returned nothing.

I also created a firewall rule on the gateway firewall to allow ports 80 and 443 outbound without any transparent proxy filtering specifically for the FOG server and it still returns this error.

[EDIT]

Also, for reference, I’m on 4991 now.

@Kris-Phillips what is in the latest fog_error log found in bin/error_logs

Where is the fog_error log you’re looking for? I’m not familiar with the path I can find that on CentOS.

Tom Elliott

What OS is this and what version is php? php -v

Kris Phillips

PHP version (php -v):
PHP 5.4.16 (cli) (built: Jun 23 2015 21:17:27)
Copyright 1997-2013 The PHP Group
Zend Engine v2.4.0, Copyright 1998-2013 Zend Technologies

CentOS Version (rpm --query centos-release):
centos-release-7-2.1511.el7.centos.2.10.x86_64

Tom Elliott

@Kris-Phillips can you follow online and install the remi repository for centos then retry installer?

Kris Phillips

@Tom-Elliott Looks like installing that repo did it. Thank you very much! I’m assuming a new package version if necessary for the latest trunk or something? Is this repo supposed to be added during the installfog.sh script?

Sebastian Roth

Sorry for leading the wrong direction. Should have thought about PHP version… sure PHP 5.4 is not happy with the current code.

Kris Phillips

@Sebastian-Roth All good! I’m very appreciative of all of your quick responses on this. Been trying to start some Windows 10 rollouts for testing and FOG 1.2 and Windows 10 are not buddies…

Any thought about doing something like php --version|grep "PHP 5" |awk '{ print $2 }' in the installer to make sure the returned value of PHP is greater than 5.5?

Sebastian Roth

Bump… would be good for CentOS fresh install as well.
