Any ways to circumvent the whole apache2.pid section?

[richardforth]

Easiest way is to use the --no-check-pid option. See --help

sorry i misunderstood the problem

Leaving this open at the moment

[richardforth]

unfortunately that particular section cannot be bypassed I thought you were referring to another section.

This ones a particular pain my my side because there are no standards and the configs are not consistent or explicit so i have to use a lot of guesswork, which is annoying.

[richardforth]

Hi

I wasnt able to replicate this in my lab, can you tell me how you came to install apache on your ubuntu 16:04 server?

Kind Regards Richard

[dutch2005]

Sure

Install webmin / virtualmin, then run it and you'll have to use the PID thingy to get it resolved.

https://virtualmin.com // http://www.webmin.com/

it stored the file (the PID in/at a non-default section, using the PID flag does fix it as it just doesnt check that thing

[richardforth]

Thanks, I will check it out.

A couple of things to note, everything I do is based off of the stock packages in each distro, by that i mean httpd as provided by yum, in centos 6 /7, and apache2 as provided by apt-get in Ubuntu and Debian.

I dont really support any third party variations eg installed from source or control panels like plesk, cPanel or Webmin/VirtualMin, however some work has gone i to make it work ina few cases, so its a bit hit and miss, I have a limited testing environment as i earn no money from this at all its purely a hobby. So i tend to stick with the mainstream package maintainers' versions of apache.

Ive used webmin before and i know that doesnt install any apache packages, so i suapect its the VirtualMin element. if its Free I will have a little play, if its a subscriber service i will have to do what I did with the cpanel guy and get you to send me some information on where I can find that pid file.

It would have been great if apache just stuck to being explicit about the exact and absolute path to the pidfile, as I could just pull that out of the config and move on with my life, as there seem to be no standards, the code that handles this looks a bit hacky:

https://github.com/richardforth/apache2buddy/blob/master/apache2buddy.pl#L1709

[richardforth]

Interesting,

im just running through the virtualmin installation on a fresh 16.04 cloudserver and it does in fact install the apache2 package but from its OWN repositories:

Brucey bonus for you:

So basically on YOUR machine, our guess at the real location was wrong:

/var/run/apache2/apache2.pid

can you please run this for me and let me know the results:

# updatedb
# locate apache2.pid

[richardforth]

Notes to self re virtualmin installation:

1  wget http://software.virtualmin.com/gpl/scripts/install.sh
2  source install.sh

[dutch2005]

root@sd-123974:~# updatedb root@sd-123974:~# locate apache2.pid root@sd-123974:~#

Looks like it it cant find the file (apache2 is running)

[dutch2005]

https://www.virtualmin.com/node/15877

Looks like it has to do with the suffix detection...

[dutch2005]

/run/apache2/apache2.pid is where I was able to find the file

Update: see screenshot: https://i.imgur.com/heCNATx.jpg

update2: seems a hotlink issue orso.. https://i.imgur.com/j09EgOx.jpg it links to a /var link, but must be something wrong in the linking as the detection to /run does not seem to exist.

[richardforth]

Yes I found that also,

I found that find /var/run/apache2 | grep pid worked for me.

[richardforth]

When you update to a later version of webmin/virtualmin you might find the problem goes away,i will see what i can do to alleviate this though

[dutch2005]

root@sd-123974:~# find /var/run/apache2 | grep pid /var/run/apache2/apache2.pid root@sd-123974:~#

Working for me aswell 👍

[richardforth]

cool,

i think i will change the final else statement to fall back to find /var/run/apache2 | grep pid

[richardforth]

just standing up another virtualmin server to apply that last change as I had dleeted my cloudservers and was about to shut down and go to bed when you replied, so im back on it.! lol

[richardforth]

Can you please try the following for me:

# curl -sL https://raw.githubusercontent.com/richardforth/apache2buddy/master/apache2buddy.pl | perl - --verbose | grep pid

then run it normally for me:

# curl -sL https://raw.githubusercontent.com/richardforth/apache2buddy/master/apache2buddy.pl | perl

Let me know how it goes

[richardforth]

do you still have access to that older machine that had the original issue?

[dutch2005]

no, but this is a recent re-install same OS, same settings and I had the issue on this one aswell (and other server )

[richardforth]

ok sweet, you happy its all working as expected?

[dutch2005]

yes, thnx for looking it up :)

[richardforth]

Sorry it took so long to get around to this I had been working on my exams (RHCE 7 coming up soon).

Glad youre happy, have a great weekend!
