Access forbbiden in accessing moodle page on web server

fperal · September 6, 2019, 11:18am

Hi.

After upgrading Opensuse leap 42.3 to 15.1 I tried to access to my moodle server through http://localhost/moodle and I got a complete blank screen.
My web server works, other pages on the server load ok.
I have been researching and it seems it may be a problem with php7 not working well with moodle, so I downgraded to php 5.6. After that, connecting to http://localhost/moodle returns

Access forbidden! You don’t have permission to access the requested directory. There is either no index document or the directory is read-protected.

/srv/www/htdocs/moodle is drwxrwxr-x+ 46 root root

with


fperal@tutatis:/srv/www/htdocs> getfacl moodle

There is no index.html in moodle, but index.php

and accessing http://localhost/moodle/index.php returns a “you have chosen to open index.php” and options “open with” “save as…” (firefox)

So, maybe is a problem with php configuration?

best regards

Please show


sudo a2enmod -l

My suspicion is that php7 is not enabled, hence the option to download instead of process.

kumado · September 8, 2019, 12:24am

I agree with Knurpht.
Php is not enabled since it is wanting you to download the php file instead of open it.
If you use Yast -> HTTP sever to launch Apache, go to the module page and check php enable.
If by command line, I think you can do php -v to get the version of php being used ( 7.2.5 as example ).
Then a2enmod php7.2.5 to enable php.
Then restart apache ( service apache2 restart ).

good luck!

fperal · September 8, 2019, 11:06pm

You were right, php was not enabled


root@tutatis:/home/fperal> a2enmod -l

I have enabled it

root@tutatis:/home/fperal>

And I restarted apache2.

But it did not change anything.

fperal · September 8, 2019, 11:15pm

I have seen that a way to test php on apache is to make a file called for instance test.php with the following content:


<?php

	phpinfo();

?>

And locate it under /srv/www/htdocs then browsing to http://localhost/test.php will show info about php.
But in my case the result is that the browser download the file

knurpht · September 9, 2019, 1:09am

AFAIK it should be


sudo a2enmod php

Where it could be that php should be php5.

fperal · September 9, 2019, 1:49am

I have changed from php5 to php7 and is the same.

I have tried as you say


tutatis:/etc/php7/cli # a2enmod php
tutatis:/etc/php7/cli # a2enmod -l
authz_host actions alias auth_basic authz_groupfile authn_file authz_user autoindex cgi dir include log_config mime negotiation setenvif status userdir asis imagemap perl python reqtimeout authn_core authz_core mod_access_compat mpm_prefork php7.2.5 php
tutatis:/etc/php7/cli # systemctl restart apache2
tutatis:/etc/php7/cli # a2dismod php7.2.5
tutatis:/etc/php7/cli # systemctl restart apache2
tutatis:/etc/php7/cli # a2enmod -l

tutatis:/etc/php7/cli #

But is always the same.

in a console php works

I have tried to add to apache httpd.conf


<FilesMatch \.php$>
    SetHandler application/x-httpd-php
</FilesMatch>

As is described here but it dindn’t work either.

knurpht · September 9, 2019, 2:04am

You need


sudo a2enmod php7

otherwise apache will not find the php7 module.

fperal · September 9, 2019, 2:35am

I was just seeing that the php module was not loaded.

Doning what you say

Now the php7_module is loaded, but it does not work either (the php file is still not processed)

Mmm. Out of ideas for the moment. Can only show you my output, I don’t have moodle installed, and it comes from my TW server:

I’m searching for some clues in log files

This is from /var/log/apache2/access_log when accessing localhost/info.php



::1 - - [09/Sep/2019:17:40:24 +0200] "OPTIONS * HTTP/1.0" 200 - "-" "Apache/2.4.33 (Linux/SUSE) PHP/7.3.9 (internal dummy connection)"

And this from /var/log/apache2/error_log

Last problem was caused for changes in apache configuration files. For testing, I’m accessing the server via local ip, so apache is using ip-bsed_vhosts.conf.

Changing to this (from the template) makes the server again return web pages (but processing of php continues failing)


 <Directory /srv/www/htdocs>
   AllowOverride None

   <IfModule !mod_access_compat.c>
      Require all granted
   </IfModule>
   <IfModule mod_access_compat.c>
      Order allow,deny
      Allow from all
   </IfModule>

 </Directory>

Now, looking at

/var/log/apache2/access_log

I can see entries anytime I access html web pages on the server, but nothing when I try to access localhost/info.php

In
/var/log/apache2/error_log

I can’t see anything when accessing localhost/info.php

All my vhosts have this, without testing for presence of modules:


 <Directory /srv/www/htdocs/SUBDOMAINFOLDERHERE/>
  AllowOverride None
  Require all granted
 </Directory>

I’m going crazy

I have tried with opera

192.168.2.2/info.php

https://susepaste.org/55666560


192.168.2.3 - - [09/Sep/2019:19:06:35 +0200] "GET /info.php HTTP/1.1" 200 73601 "-" "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/71.0.3578.98 Safari/537.36 OPR/58.0.3135.68"
192.168.2.3 - - [09/Sep/2019:19:06:36 +0200] "GET /favicon.ico HTTP/1.1" 200 302 "http://192.168.2.2/info.php" "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/71.0.3578.98 Safari/537.36 OPR/58.0.3135.68"
192.168.2.3 - - [09/Sep/2019:19:07:17 +0200] "-" 408 - "-" "-"

Processes the php and works

But with firefox it still return the “save file” dialog … and … it was the file was cached. Opening a private window in firefox and going to 192.168.2.2/info.php works well also.

But 192.168.2.2/moodle return a blank page.
So maybe now what I have is php working but moodle not working well with php

I have inherited the apache configuration from previous ones, I have the compat module activated. I think I should tidy up a little.

fperal · September 10, 2019, 11:50am

Solved!!

It was not an error but three

First)
When updating, some configuration files of the webserver are changed. Were I previously had


<Directory /srv/www/htdocs>
   AllowOverride None

   <IfModule !mod_access_compat.c>
      Require all granted
   </IfModule>
   <IfModule mod_access_compat.c>
      Order allow,deny
      Allow from all
   </IfModule>

 </Directory>

So access to the server is allowed, the upgrade cahnge some of them to “Requiere all denied” so it blocked the access to /srv/www/htdocs
(maybe it happened when trying to change apache configuration with YAST)

Second) php extension was not (properly) enabled in apache.
To configure it I had to run (for php5)


#a2enmod php5

o (for php7)


#a2enmod php7

You can list which modules are enabled with


#a2enmod -l

But yo need to know which modules are really running with


#apache2ctl -M

Once enabled, test it placing a file called info.php in /srv/www/htdocs


<?php

  // Show all information, defaults to INFO_ALL
  phpinfo();

?>

restart the web server


#systemctl restart apache2

And check that php is really running, browsing http://webserver/info.php

Third) Moodle only support php7 from version 3.0.1 upwards, as described here As my moodle is version 2 I needed to downgrade to php5 (Opensuse leap 15.1 uses php7 by default).

Thank to everybody

best regards.
