PostPosted: Mon 01 May '17 14:37    Post subject: Apache2 down after package update Reply with quote

Glad to be aboard and make my 1st post. Have used Apache flawlessly for probably over a decade - thanks to all who have been involved maintaining it so well. The other day, it finally has given me a serious problem and wont come back up after the latest update.

I have posted to a number of other support forums for Linux as well as to my former ops guy and still Apache is down for about 2+ days now. Here is basically a cut and paste synopsis of the problem and whats been done, sorry if it looks messy but I'm in an endless loop of sorts.... Sad any help appreciated. Sorry if this is too long and I should have used hastebin, but its my first time here and hard to know where to begin.

Note: Apparently I'm stuck using PHP5.6 for the time being as an older web portal cannot use the new sql commands now present in 7.x. Not sure if that is an issue, but I do have (2) other plain http/s sites on the server so should be ok afaik.

(1st post of problem)
======================================================
Did the usual package updates today from Webmin, all went ok except when
upgrading Apache2. There was a timeout, and the service never restarted
during the upgrade process.

I did a purge and remove via bash, and a reinstall , but still no go.

Im not sure if its because I enabled mod_rewrite and there is a new path or
something, but thats
the only change thata major I did with Apache after trying to get the sites
more SEO friendly recently.
There may have been 1 other module enabled, but I cant remember what it was.
I went in and turned on rewrite
and we are still failing.

=================================================
Thought I would try a rollback so tried a purge and remove via bash, and a reinstall , but still no go.


apt-get install apache2=2.4.18-2ubuntu3.1


ran the journalctrl
command and it says:

======================================================

Did another purge and reinstall -
apt-get install apache2=2.4.18-2ubuntu3.1

But it said there were 2 dependencies missing.

Someone else on another help list said:
======================================================
The missing dependencies are probably apache2-data apache2-utils . Try
"apt-get install apache2 apache2-data apache2-utils"
======================================================
Tried that,
...seems like those go in and still it tries to put in apache
2.4.25 even after its purged?

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
apache2 : Depends: apache2-bin (= 2.4.18-2ubuntu3.1) but
2.4.25-3+deb.sury.org~
xenial+1 is to be installed

Update:

Ok, I didnt see my former ops guy seems to have isolated at least part the issue, apparently its because we are using the Froxlor web management system:


AH00526: Syntax
error on line 12 of
/etc/apache2/sites-enabled/10_froxlor_ipandport_139.162.211.216.443.conf:
Apr 30 21:55:27 apache2[18292]: Invalid command
'Action', perhaps misspelled or defined by a module not included in the server configuration


So I guess we will pickup from there and see how it goes. Apparently Froxlor is allowing us to run php5.6 fastcgi in conjunction with Apache or something to that effect.

1 question I think u guys can probably answer -

Is there a "rollback" option with the apache releases?
If not, would be a good idea here for my case, as a rollback to last known good configuration would most likely have my sites back up at least.
