"Could not find Apache process. Exiting..."

[stephen304]

I have apache2 installed via apt-get on ubuntu 13.10 x64. Here is the output of apachebuddy:

########################################################################

So you can see it finds apache2, but it somehow doesn't think it's apache...

I'm running Apache2 behind Varnish, and no luck...

Easy fix in my case:

perl apachebuddy.pl --port=8080

[stephen304]

The problem for me is that apahe is running on port 80, not 8080... yet apachebuddy still won't recognize it.

I'm seeing the same issue as @stephen304. I initially installed via Ubuntu 13.10 but recently upgraded to 14.04 LTS.

Same output as willtate
Ubuntu 14.04 LTS Server 64bit
Clean install on 14.04, basic apache install, no varnish
$apache2 -v

CAUSE : CAPITAL V unnecessary for the purpose of the function to ID apache.
On my system it invokes
sudo /usr/sbin/apache2 -V
which outputs nonsense only, no versions.
sudo /usr/sbin/apache2 -v just gives a version without a mile of complaints first which throw perl off as it looks for the id in the first line of output only.

SOLUTION TO JUST THIS STEP - which basically only hides the underlying problem so apachebuddy does recognise it is apache.
CHANGE
my @output = $process_name -V 2>&1;
to
my @output = $process_name -v 2>&1;

that got me past that issue - but onwards into other ones..... Ubuntu really changed about a lot of apache structural stuff with 14.04. Paths, splitting up configs etc. mucho broken :/ /usr/sbin/apache2 cant really be invoked in this way. for more info, see the default index.html file on a fresh install of 14.04, it talks a lot about what changed and is unusually informative.

Rename issue to compatibility with Ubuntu 14.04 LTS apache2

[BillyGriffiths]

Experience same issue on 14.04 LTS. Anyone have a workaround for this yet?

Experience same issue on 14.04 LTS w/ Apache 2.4. States constants set by envvars do not exist or the script can't read them when loading /etc/apache2/apache2.conf.

#22 addresses the issue. Long story short running apache2 does not load the env vars, however apache2ctl does. I tweaked a regex to deal with the different format for the compiled modules. I'm pretty sure this solution will not work for everyone, so I wouldn't merge as is unless someone else really puts it through its paces.

[manuelsdt]

I've got the same issue on 14.04 (14.04.1 LTS codename trusty) running apache2. I don't really understand how to try the fix above (#22), can anyone explain?

You can just yank the code from my fork:
https://github.com/xn/apachebuddy.pl

[manuelsdt]

xn, thanks a lot, didn't realize it was that simple, this is my first use of github. This worked flawlessly for me.

[xn]

No worries. Great to hear. Open source for the win!

[manuelsdt]

I missed something the first time around. I'm still getting this:

"Unsuccessful stat on filename containing newline at ./apachebuddy.pl line 125 (#1)
(W newline) A file operation was attempted on a filename, and that
operation failed, PROBABLY because the filename contained a newline,
PROBABLY because you forgot to chomp() it off. See "chomp" in perlfunc."

Does this matter or something to just ignore?

[xn]

I just updated my fork, you can try that.

[manuelsdt]

Beautiful. Works perfect without any errors now! Thanks so much!

[davidak]

I have also the problem on 14.04 LTS with a Plesk install (Apache behind Nginx). Also the fork don't work for me.

[xn]

What is the process running under?

[xn]

you can run this to see if you get the correct pid:
ps aux | grep -v grep | egrep '^root.*(httpd|apache2)' | awk 'BEGIN {ORS=""} {print $2}'

[xn]

if it does, you can edit this line: https://github.com/xn/apachebuddy.pl/blob/master/apachebuddy.pl#L974
to:

$pid = ps aux | grep -v grep | egrep '^root.*(httpd|apache2)' | awk 'BEGIN {ORS=""} {print $2}' ;

[billynoah]

I am under the impression that Apache 2.4+ doesn't even use the MaxClients directive which has been replaced by MaxRequestWorkers. Presumably there are other changes as well which would require a more thorough examination of this script and it's recommendations.

[ksashikumar]

This worked for me:
curl -sL apache2buddy.pl | perl

[hrazouk]

Hello when do curl -sL apache2buddy.pl | perl I receive curl -sL apache2buddy.pl | perl Please help

[hrazouk]

sorry I receive There are multiple PIDs listening on port 80
