mod_pagespeed 1.9.32.2-4321 Permission denied opening temp file

[apacher]

Hello,

I have updated to mod_pagespeed 1.9.32.2-4321 beta release and some images doesn't appeare on my webpage.

I am getting error messages like this

Opening temp file: Permission denied

[Thu Oct 30 00:29:02 2014] [error] [mod_pagespeed 1.9.32.2-4321 @12xxx] /var/cache/mod_pagespeed/rname/ic_BZ3prteTLgXCEiu38qzB/http,3A/,2Fewww.mydomain/some_image.jpg,42d,40tps_,.tempuTVeQO:0: opening temp file: Permission denied

Joomla! 3 website using varnish cache debian wheezy 32bit

I switched back to the stable version and it looks like error messages are gone, images loaded on my pages again. Everything is ok.

(I just reported it. I do not know if it happens only with my configuration.)

Can you check the ownership of directory /var/cache/mod_pagespeed, and make sure it's the same as the processes running Apache?

I'm guessing the owner of both should be 'www-data'.

Note: Currently I am using the latest stable version. mod_pagespeed 1.8.31.5-4307

(Should I switch back to beta channel and  check the ownership again? )

You might as well.  We'll mark the newly patched beta stable if all goes well for a few weeks, so we might as well sort this out now.  Do you get these error messages if you just do something like:

sudo chown -R www-data /var/cache/mod_pagespeed

It'd be great to understand how it comes to pass that 'myusername' is the owner of these files.  Are you dabbling with an Apache MPM that uses suexec or something so that each vhost runs under its own user ID?

So what I did.

Reinstalled mod_pagespeed 1.9.32.2-4321 (removed stable 1.8.31.5-4307)

I deleted the cache using - touch /var/cache/mod_pagespeed/cache.flush

(I am using Varnish cache 3.x so I also restarted varnish to recache the webpages.)

Then I checked the error logs  tail -10 /var/log/apache2/error.log

and error messages appeared immediately

opening temp file: Permission denied

 /var/cache/mod_pagespeed/rname/ic_ebumligxxxxx9pofEmeI/http,3A/,2Fsome_thing.com/images/home.png,40x,40v_,.temptLom5I:0: opening temp file: Permission denied

I checked the ownership in folder

ls -l /var/cache/mod_pagespeed/

-rw-r--r--  1 root     root         0 Nov  1 03:54 cache.flush

-rw-------  1 myusername    myusername       13 Nov  1 03:11 !clean!time!

About your last question: This is a normal default debian 32 bit installation. No Apache MPM afaik.

I see that a few months ago you had the exact same problem with MPS 1.8, from this thread:

Did those chmod commands work?

Also -- is there any chance you are running SELinux?  Please see this bug from a couple of years ago:

(You are right, I completely forgot that the same issue has already happend. I only remembered that I had issues on stats_log_global permissions.)

I gave a+w write permission on all files under /var/cache/mod_pagespeed recursively

and it looks like permission errors are gone, both stable and beta channel was tested.

Sorry for the trouble and thank you for your time!

It is curious that you are again having this problem and I wonder if there's something that you are doing in your flow that causes folders to be created under your own username.  it is probably not a great idea to run, long-term, with your cache directory set as world-writeable.  You definitely would need to trust everyone that can ever gain any kind of access into your machine.  I would look for a way to try to ensure that all the writers of your file-cache are the same user (usually www-data).  Make sure the file-cache directories are owned by www-data and investigate why anyone else needs to read or write.

I'm having the same problem but I think it's because I'm using mpm_itk_module which changes the user based on the vhost.
Is there any way to change the cache directory for mod_pagespeed on a per vhost basis?

Sorry, my inexperience showing here.

I was of course able to set the cache directory from within the vhost

pagespeed.conf

<IfModule pagespeed_module>
    ModPagespeed off
    ...
    ...
    ModPagespeedLogDir "/var/log/pagespeed"
    ...
    ...
</IfModule>

vhost file

    <IfModule mpm_itk_module>
        AssignUserId ********* users
    </IfModule>
   
    <IfModule pagespeed_module>
        ModPagespeed on
        ModPagespeedFileCachePath "/var/cache/mod_pagespeed/*********/"
    </IfModule>

Where ********* is the username
