Did a world update, PHP now not working on my localhost. It was prior to the update. A PHP file displays the code in a browser.

This is what shows up in the apache error.log:

Code:

[Tue Jan 04 10:04:49 2011] [error] [client 71.163.19.220] client denied by server configuration: /var/www/localhost/htdocs/mohachat/lib/
[Tue Jan 04 10:04:49 2011] [error] [client 71.163.19.220] client denied by server configuration: /var/www/localhost/htdocs/mohachat/config/
[Tue Jan 04 10:05:41 2011] [error] [client 71.163.19.220] client denied by server configuration: /var/www/localhost/htdocs/mohachat/lib/
[Tue Jan 04 10:05:41 2011] [error] [client 71.163.19.220] client denied by server configuration: /var/www/localhost/htdocs/mohachat/config/


I run a moha chat server. I didn't change anything in the moha chat configuration. All I did was run a world update.

This is very frustrating. Something breaks every time PHP or Apache updates on Gentoo.

I don't know if I remember that correctly, but perhaps I solved such a problem in the past by re-emerging apache.

Edit: did you restart apache yet?

Best regards,
Jimini

The first thing I did was restart apache, which didn't help.

Then I tried re-emerging apache, which didn't help.

Then I re-emerged apache with APACHE2_MODULES="cgi", because the output of Portage said that cgid or cgi is now required, and since I don't use threaded, I set cgi.

Now I get this when trying to start apache:

Code:

 * apache2 has detected an error in your setup:
Syntax error on line 90 of /etc/apache2/modules.d/00_default_settings.conf:
Invalid command 'Order', perhaps misspelled or defined by a module not included in the server configuration
 * ERROR: apache2 failed to start


:evil:

This was an upgrade to PHP 5.3.4. I'm downgrading now to see if that works.

Works fine for me. Did you try following the PHP Upgrade Guide?
There were quite a few changes since PHP 5.2x - though as you've not provided any information as to what was upgraded during your "world update", it's difficult to help you troubleshoot any further beyond recommending the above guide.

I emerged the stable versions of LAMP. I can't get PHP to work now. I tested a simple page:

Code:

<?
echo "It works!";
die("Please, just die!");
?>


Nothing. Blank page. Ctrl-u in Firefox shows me the PHP code, but the browser itself shows a blank page.

HELP! :roll:

Try running
Code:
eselect php list apache2

and then selecting the version you want with
Code:
eselect php set apache2 <num>

(then restart apache)

PHP is slotted now, and after I upgraded I found that no version was selected by default, so I had to manually select one.

If that doesn't work could you post the output of
php -v
cat /etc/conf.d/apache2
and
ls -l /usr/lib/apache2/modules

Usage of <?/<?= forms instead of <?php/<?php echo implies short_open_tag to On.

Code:
Syntax error on line 90 of /etc/apache2/modules.d/00_default_settings.conf:
Invalid command 'Order', perhaps misspelled or defined by a module not included in the server configuration

It seems authz_host module is absent (absent from APACHE2_MODULES when emerging or not loaded).

Code:
[Tue Jan 04 10:04:49 2011] [error] [client 71.163.19.220] client denied by server configuration: /var/www/localhost/htdocs/mohachat/config/

Don't, access to lib and config subdirectories, need to be restricted ? If it shouldn't, there is a Deny directive somewhere in your Apache configuration or in a .htaccess file in your application directories.

That didn't work. :cry:

Editing /etc/php/apache2-php5.3/php.ini to change short tags to on resolves the issue of testing a simple script as I described earlier; however, trying to run something like ajax chat or Moha chat from my localhost still results in a blank page after trying to log in (ajax chat) or run the web installer (Moha).

What condition would allow a simple echo script to work but not a server app written in PHP?

Apache haven't write permission where it should? A missing PHP function/extension? (mohachat seems to need, at least: apache2 sockets zlib session and mysql or postgres as php USE flags)

Nothing related to PHP in Apache error log? (no "undefined function" or "permission denied" in particular for example?)

If none, try to change display_errors to On and error_reporting to E_ALL & ~E_DEPRECATED (from php.ini - really preferred ; or eventually in Apache configuration/.htaccess by adding these two lines : php_flag display_errors on and php_value error_reporting 22527).

PS: to have php command, PHP must be emerged with cli as USE flag.

I have PHP compiled with the cli use flag and I still get the file not found error.

This is what shows up in apache's error log when I restart apache, go to a fresh mohachat install page and click "next" from the first page:

Code:

[Wed Jan 05 14:05:45 2011] [notice] Apache/2.2.16 (Unix) mod_ssl/2.2.16 OpenSSL/1.0.0c configured -- resuming normal operations
[Wed Jan 05 14:05:53 2011] [notice] child pid 5802 exit signal Segmentation fault (11)
[Wed Jan 05 14:05:53 2011] [notice] child pid 5803 exit signal Segmentation fault (11)
[Wed Jan 05 14:05:55 2011] [notice] child pid 7161 exit signal Segmentation fault (11)


Something is bjorking somewhere. How do I find out what?

I had errors set to E_ALL & E_STRICT. I changed them to E_ALL & ~E_DEPRECATED, but that didn't seem to affect anything.

I had moha running fine before my last world update. Everything it requires should still be in place, other than PHP deciding to have a party on my server.
