SVN 4380 Cloud 5419 (on Ubuntu 14.04.3) - Fog Client (404) Not Found.

Malos

Ubuntu 14.04.3
SVN 4380 Cloud 5419

On a fresh install, an upgrade to newer trunk version, or a reinstall of the existing fog_trunk contents, FOG clients will begin to throw 404 errors for everything;

11/18/2015 12:50 PM Middleware::Communication URL: http://fog-server/fog/service/servicemodule-active.php?moduleid=clientupdater&mac=90:B1:1C:7D:6B:FF||00:00:00:00:00:00:00:E0&newService=1
 11/18/2015 12:50 PM Middleware::Communication ERROR: Could not contact FOG server
 11/18/2015 12:50 PM Middleware::Communication ERROR: The remote server returned an error: (404) Not Found.

Going off of constant refreshing the folder view while running a couple installs, I’m guessing the symbolic link (which I had to manually create in the first place) gets wiped out right around this area here:

 * Backing up old data.........................................OK
 * Copying back old web folder as is...........................OK
 * Copying new files to web folder.............................OK

Here’s the fix, just needs to be run once install.sh has finished completely:

Make a symbolic link at /var/www/html for fog, and point it at /var/www/fog

ln -s /var/www/fog /var/www/html/fog

Ta-da, no more 404s!

I’m pretty sure I do this already but in reverse . Apache moved from var www to var www html with Ubuntu 14 so I now move data there unless told otherwise . It does a double link it creates a link to itself inside itself so /var/www/html/fog/fog as well as create a link from /var/www/html/fog to /var/www/fog

Malos

@Tom-Elliott I can tell you that after upgrading to the SVN 4393 (latest as of this post) , /var/www/html only contains the default apache2 index.html, still consistent with the behavior noted in my OP

Is your fogserver actually named fog-server?

Malos

@Tom-Elliott no it’s not. The server itself is named fogserver at the OS level, and I have DNS entries that resolve fog-server, fogserver and fog (just covering my bases), all resolve to the correct IP.

That fog-server entry in the logs is due to me being lazy and next nexting with installing the client in this case.

Malos

@Tom-Elliott This is reproducible, here’s the steps that I have recorded in my wiki;

Install Ubuntu Server 14.04.3 LTS from iso
sudo passwd root
set your static IP info
su - up to root, and run
apt-get update && apt-get -y dist-upgrade && shutdown -r now
once it’s back up:
apt-get install -y subversion && svn co https://svn.code.sf.net/p/freeghost/code/trunk@4393 /root/fog_trunk && cd ~/fog_trunk/bin/ && ./installfog.sh

Run through the install as usual, and perform a
ls /var/www/html
Result: no fog folder/link. Creating it manually does resolve client connectivity, but a re-running of installfog.sh wipes out the manual link.

Tom Elliott

I make a link from /var/www/html/fog to /var/www/fog and I also make a link from /var/www/html/fog/ to /var/www/html/fog/fog

This way even if hte webroot is not with a /fog, clients don’t have to adjust anything.

My best guess is that the /var/www/ is your current document root, but the /var/www/html is the “real” document root of your server.

You can verify this in the /opt/fog/.fogsetting and look for the docroot= setting in the file.

Malos

@Tom-Elliott Running a

grep -n -e "DocumentRoot"  /etc/apache2/sites-available/*

results in

/etc/apache2/sites-available/000-default.conf:12:       DocumentRoot /var/www/html
/etc/apache2/sites-available/001-fog.conf:4:    DocumentRoot /var/www/
/etc/apache2/sites-available/001-fog.conf:12:    DocumentRoot /var/www/
/etc/apache2/sites-available/default-ssl.conf:5:                DocumentRoot /var/www/html

/opt/fog/.fogsettings has

docroot="/var/www/";

Tom Elliott

@Malos can you change the document root in fogsettings file to /var/www/html and rerun the installer?

Malos

@Tom-Elliott
As you suggested, changing in opt/fog/.fogsettings

docroot="/var/www/";

to

docroot="/var/www/html/";

and then r erunning the installer does create /var/www/html/fog, and creates a link to said folder at /var/www/fog

After re-running the installer, clients are able to connect no problem.

Malos

@Tom-Elliott Will some kind of change be made within the installer to reflect a new document root for fog? I don’t know when apache2 changed their doc root, or if that’s an ubuntu thing

Tom Elliott

Installer can accept arguments to specify webroot and docroot as you see fit.

The installer tries to take the best guess of information, but it’s all a guessing game.

Malos

@Tom-Elliott Ah, ok very nice.

./install.sh -?

indicates that I can use the following to install fog trunk with a correct DocRoot on Ubuntu 14.04.3

./install.sh -D /var/www/html/

Thanks!
