Access denied for root@localhost
-
I think maybe Ubuntu pushed a patch to fix the upgrade thing? I can’t reproduce it any longer anyway.
Anyway, after running that command inside of mysql I can now connect as a regular user to the database and the schema updater no longer shows up!
-
As you say, it seems unable to create tasks and such, which is troublesome.
Also, this apache error is generated every 0.25seconds or so:
[Wed Apr 27 10:43:47.795413 2016] [:error] [pid 20862] [client 192.168.1.31:55867] PHP Warning: implode(): Invalid arguments passed in /var/www/fog/lib/fog/eventmanager.class.php on line 67 (I’m guessing it’s complaining about empty string?)
Looking at the file it seems to be related to plugins (I have none installed currently)
Also, the FOG Settings page shows no settings anymore.
Guess I jumped the gun a bit with upgrading to 16.04 heh.
-
FOG Services are dumping a ton of php errors, I’m guessing Ubuntu changed something about php/apache as well?
[Wed Apr 27 11:38:44.437447 2016] [evasive20:error] [pid 3521] [client 192.168.1.154:56732] client denied by server configuration: /var/www/fog/status/getfiles.php
Seems like there’s some security changes getting in the way?
-
I think ubuntu renamed php packages for this release. I purged php and apache and now the foginstaller is unable to find packages with php5 in its name. Looks like it only supports php 7!
Looks like this is turning into the great Ubuntu 16.04 bug thread heh.
edit: following Tom’s instructions from the php 7 thread https://forums.fogproject.org/topic/6285/php-7-0-0-finally-released/16
Results in the installer being unable to add the repositories (probably because it still refers to the old repositories rather than the new ones)
Ubuntu now refers to php7 packages as simply php it seems! Which brings it in line with Redhat systems.
Also, Apache2 evasive mod has blacklisted my IP lol.
Installer now gets stuck on stopping the web service.
php-msqli was missing so had to manually install it. Installer still stuck though.
Found this in the installer error log:
Failed to stop php5-fpm.service: Unit php5-fpm.service not loaded.
Tries to stop a service that’s of course not installed causing it to fail.
Fixed it using Tom’s instructions of the php 7.0 thread but changing it slightly:
php_ver="7.0" php_verAdds="-7.0" repo="php"
The repo is simply php, but the packages can still be referred to as 7.0, however apt will generally pick the correct php package by simply referring to them as php.
The installer now makes it to Backing up database where it fails!

@Quazz Sounds, to me, that you may need to install php7.0-mbstring?
-
@Tom-Elliott It was indeed not installed! Installation now completes!
Still getting the same issues as before on the webui however, which I’m guessing has a lot to do with php7 and less with anything else?
-
@Tom-Elliott Tried to update to 7334.
Installer fails to update the database. No errors to be found in the installer error logs.
-
@Quazz said:
Still getting the same issues
Which issues/errors exactly? The mysql 5.7 stuff or what?

-
@Hanz I cannot see how this is related to the topic of Ubuntu 16.04 mysql issues!?! Please help me.
-
@Sebastian-Roth Unable to create tasks, no fog settings being displayed, the php error spam.
Mysql seems to work fine now (assuming it’s not causing the other issues that is)

Images are unable to deploy (input/output error).

The other php errors have no longer showed up since Tom’s tomfoolery
-
you should dump Ubuntu for this:
https://www.turnkeylinux.org/lampstackinstall is SO easy and the features of the stack are good too.
-
Added subnet to evasive mod whitelist to get rid off a bunch of stupid errors (it kept on blocking getfiles.php)
Perhaps worth noting that both php7.0-mbstring and php-mbstring exist and are in fact different packages. (why…)
-
I think we need to face 16.04 at some point to I am trying to get a wiki article together: https://wiki.fogproject.org/wiki/index.php?title=Ubuntu_16.04
-
I found the solution for me in this article: https://www.percona.com/blog/2016/03/16/change-user-password-in-mysql-5-7-with-plugin-auth_socket/
basically comes down to the following as the fix :
sudo mysql -u root
ALTER USER ‘root’@‘localhost’ IDENTIFIED WITH mysql_native_password BY ‘password’;
exit -
-
@Wayne-Workman Sorry, but that’s a bit of a different story as Ubuntu 16.04 comes with MySQL 5.7 which defaults to something called
auth_socket
in contrast to normal tcp localhost socket connection. -
@Sebastian-Roth Is there any way to address this in the installer so that it works out of the box for Ubuntu 16?
-
@Wayne-Workman Yes, force people to set a MySQL root password when installing. But it would still fail if people have MySQL server pre-installed (with empty password)… Other than that I don’t think we have any chance to hook into the
auth_socket
thing. See if you can find anything related to php and auth_socket
