Services are not running. Where are the logs?

Tom Elliott

I don’t know how things are running.

Yes it’s normal for people to obtain root sudo su but it’s not giving you the full layer of root’s necessary actions. This presents strangely only on the “debian” based systems that I’ve run into. It’s very tedious and cumbersome to trace issues because you naturally think “I’m already root” but the way things are logged in are not all the same.

yes running sudo ./installfog.sh should work, but I just don’t know all the scenarios this may have issues with.

Sebastian Roth

@dolf Although it seems to not do the trick in your case Tom is right about saying that sudo su does not give you a real proper root shell. While it does switch the user it does not load all the environment (/etc/profile and ~/.bash_profile) which might give you a different behavior in some cases. I have seen issues where starting some of the init services would work but restarting the squid web proxy would just not! Never found out why that is. I suppose it’s the PATH variable not being set properly (/sbin and /usr/sbin missing).

Good you found the init PHP files. Obviously was a bit distracted when I wrote this. What if you run one of the scripts by hand /opt/fog/service/FOGImageReplicator/FOGImageReplicator??

dolf

Eureka! It says:

Missing Extensions: mysqliroot

Sebastian Roth

@dolf Please run this find / -xdev -fname "php.ini*" -exec grep "extension" {} /dev/null \; and post the output here.

dolf

I took the liberty of first:

Correcting the command: find / -xdev -name "php.ini*" -exec grep "extension" {} /dev/null \;
Uninstalling php5 (since I have php5.6 installed, too)

Here is the output: php_extensions.txt

Then I tried this:

# apt-get install php5.6-mysql
# phpenmod mysqli

It runs! BUT there is another error:

PHP Fatal error:  Call to undefined function curl_init() in /var/www/html/fog/lib/fog/fogurlrequests.class.php on line 49

But it didn’t stop running, and a log file appeared at /opt/fog/log!

dolf

And then:

# rm /var/run/fog/*

But after a reboot, they are not running any more:

All of the logs in /opt/fog/log contain the same thing:

They fail to start using service FOGxxx start, since the pids still exist in /var/run/fog. Deleting those and starting manually as in the beginning of this post works.

@dolf said in Services are not running. Where are the logs?:

Call to undefined function curl_init() in

If you run:
sudo apt-get install php5-curl Then:

sudo service FOGMulticastManager stop
sudo service FOGImageReplicator stop
sudo service FOGSnapinReplicator stop
sudo service FOGPingHosts stop
sudo service FOGScheduler stop
sleep 10
sudo service FOGMulticastManager start
sudo service FOGImageReplicator start
sudo service FOGSnapinReplicator start
sudo service FOGPingHosts start
sudo service FOGScheduler start

I think you’re close now.

My bad. I didn’t enable the apache php5.6 module after uninstalling php5.

# a2enmod php5.6
# service apache2 restart

Still didn’t work. It seems like I broke my php and/or webserver. After reading this, I noticed that the php mime config was missing. So I did the brave thing and purges all versions of php and apache from my server. Starting over…

dolf

AHA! After purging all forms of PHP and Apache from my server, I re-ran the fog installer. (Discovered some apt issues with old and obsolete packages. Killed those by uninstalling everything that I don’t need. Ran the fog installer again. Then it worked.) Still got errors about mysqliroot and curl_init() being missing, but then I had this idea:

Apache2 is using the php5 module, so it always invokes php5. php5-curl and php5-mysql were installed. But the fog installer also caused php7.0 to be installed. php7.0-curl and php7.0-mysql were not installed. So I checked which version was being used on the command line:

# update-alternatives --config php
There are 2 choices for the alternative php (providing /usr/bin/php).

  Selection    Path             Priority   Status
------------------------------------------------------------
* 0            /usr/bin/php7.0   70        auto mode
  1            /usr/bin/php5     50        manual mode
  2            /usr/bin/php7.0   70        manual mode

Press enter to keep the current choice[*], or type selection number: 1
update-alternatives: using /usr/bin/php5 to provide /usr/bin/php (php) in manual mode

Sure enough, it started working after changing from php7.0 to php5. All services are running, even after a reboot.

I am a happy bloke.

@dolf Great to see you got this sorted! Seems like the system was a bit messed up.

Wayne Workman

@dolf I guess another route would be to install those php 7 things.

Sounds to me like you didn’t install FOG on Ubuntu 14 with the recommended command for php7. Let me find that…

here’s the command to have FOG use all PHP 7:

php_ver='7.0' php_verAdds='-7.0' ./installfog.sh

If running Ubuntu 16, you’ll need to use that command to start the installer, and THEN when it asks for the DB to be updated - You’d go into MySQL and make a tweak to the root user:
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '';
And then continue to the web interface to update fog.

I’m on Ubuntu 14.04 though…
Anyway, it’s working with php5.

Services are not running. Where are the logs?
