Restarting Apache2 for fog vhost Failed!

[jeffj]

Server

• FOG Version: 1.3 RC-14
• OS: Ubuntu 16.04

Description

So I have been working on getting fog installed on the ubuntu 16.04…

obligatory I know I shouldn’t upgrade the os willy nilly because it causes problems most of the time.

never the less I have done it and I am having problems on the install. this is an upgrade, btw it was on 14.04 and the fog version was 1.3 RC-8.

I have read though the other posts pertaining to installing on 16.04 and it appears some people have had mixed results when installing this. Unfortunately, I have not had any luck getting it to work.

I have commented out the packages line in the .fogsettings and deleted the php version info from php-var and php-varadd lines. everything appears to install fine up to the restarting of apache2 which fails.

when checking the status of apache2 after the failed install shows it is failed (result: exit code).
I also checked the fog error log in the /foginstalllocation/bin/error_log(s) folder and this is what is at the end of the log:

After the failed install apache2 will not restart until i purge and re-install it

I noticed these lines in particular

Oct 18 10:00:50 fog apache2[20583]: apache2: Syntax error on line 140 of /etc/apache2/apache2.conf: Syntax error on line 1 of /etc/apache2/mods-enabled/php.load: Cannot load /usr/lib/apache2/modules/libphp5.so into server: /usr/lib/apache2/modules/libphp5.so: cannot open shared object file: No such file or directory

I am guessing some config file for apache is being changed which breaks it.

Thank you ahead of time for your help!

Edit: Here is some more information to maybe help resolve this problem.

when running dpkg -l | grep php this is the output

So what is line 140 of /etc/apache2/apache2.conf and line 1 of /etc/apache2/mods-enabled/php.load ?

[jeffj]

apache2.conf line 140:

IncludeOptional mods-enabled/*.load

php.load line 1 (also happens to be the only line):

LoadModule php5_module /usr/lib/apache2/modules/libphp5.so

something to note the php.load file only exists after I run the installer for fog before it does not exist.

Edit: I checked the /usr/lib/apache2/modules/ folder and there is a libphp7.0.so I believe that is where the problem lies. though fixing it i am unsure how to do.

[Wayne Workman]

@jeffj said in Restarting Apache2 for fog vhost Failed!:

LoadModule php5_module /usr/lib/apache2/modules/libphp5.so

Change that to this:

LoadModule php7_module /usr/lib/apache2/modules/libphp7.so

And just see what happens. I don’t know if it will fix it or not.

In such case, make the line into:
LoadModule php7_module /usr/lib/apache2/modules/libphp7.0.so

Then try to restart apache.
service apache2 restart
service apache2 status -l

@Wayne-Workman

when doing that and trying to restart apache2 it errors out here are the error details

@jeffj I’m willing to keep helping you troubleshoot this - but from experience here with other people in your boat, it would most likely be faster to rebuild the server clean and fresh with Ubuntu 16 because rebuilding would only take perhaps a few hours. Your problems here could take days to try to resolve, just from past experience. You might also read through this: https://forums.fogproject.org/topic/8775/when-rebuilding-a-fog-server

[jeffj]

@Wayne-Workman

as much as I hate giving up on fixing a problem it appears that rebuilding will be the easier route. thanks for the link for rebuilding fog server I was unaware of how to copy the images and and migrate them to a new server.

[Tom Elliott]

@jeffj I think this is overly much. Rebuilding is not necessary.

Please run: (if you haven’t rebuilt already):

rm -rf /etc/apache2 /etc/php*
sudo apt-get remove lib*php* apache2* php5* php7*

Then rerun the installer.

[jeffj]

@Tom-Elliott

okay after running those commands and re-running the installer it now fails when installing package php7.0-fpm

the fog error log has this to say:

@jeffj let me remote in and I had to enable two items to get things working. Once done I’ve added to the functions.sh file to make this more autonomous.

Fresh 16.04 should work fine, but an upgraded 16.04 should work too now (at least with minimal effort as needed/required.)

[jeffj]

@Tom-Elliott

Thanks again tom! marking as solved.

[Wayne Workman]

@Tom-Elliott Cool. I’m still going to advise against updating the OS though. It causes way too much noise in my day, and imagine people coming from 10 and 12 ? No telling what sort of problems that brings.
