LDAP Plugin to AD, ldap_unbind function ERROR

Sebastian Roth · May 15, 2019, 1:01 PM

@Alois I suggest we start by creating a phpinfo page to get an idea of the version currently running. Create a new file /var/ww/html/fog/info.php with the following content:

<?php
phpinfo();
?>

As well make it owned by the apache webserver user: chown www-data:www-data /var/ww/html/fog/info.php

Try open the following URL and post a picture of the output you get: http://x.x.x.x/fog/info.php

@Sebastian-Roth I suspected that you would ask that I had already taken the initiative to do so.
Here is the result :
https://gyazo.com/9bcdd3af409b50998a094d1e5cf13c13

but php -v send me this result :

PHP 7.2.18-1+0~20190503103213.21+stretch~1.gbp101320 (cli) (built: May  3 2019 10:32:13) ( NTS )

I tried to remove the php5 files, but the server returned me a 503 error.
I think I’m using the wrong method to delete.

Thank you

@Alois Ok it’s still using PHP 5.6 in the webserver. Note that php -v is giving you different results because command line PHP is not always the same as the one used by apache.

Please post the contents of /etc/apache2/sites-enabled/001-fog.conf here. As well run the following commands and post output here:

ps ax | grep fpm
systemctl status php7.0-fpm.service
systemctl status php7.2-fpm.service

Thank you for taking your time to help me.

@Alois Let’s first try to get rid of the old PHP 5.6 and make sure the FOG web UI is still running:

apt-get purge php5 php5-cli php5-common php5-curl php5-fpm php5-gd php5-json php5-mcrypt php5-mysqlnd php5-readline libapache2-mod-php5
systemctl restart php7.2-fpm.service
systemctl restart apache2.service
systemctl status php7.2-fpm.service
systemctl status apache2.service
dpkg -l | grep php5

Now try to access the web UI. If you get any error make sure you copy&paste the full command and output here so we know exactly what happened and can help you.

Thank’s

@Alois Sorry for my late reply, had too much work today and couldn’t respond in between. Please take a look at the apache error log to see why it fails. You find that log in /var/log/apache2/error_log

Get the last 20 lines of that file and post here.

EDIT
I change in /etc/php/7.2/fpm/pool.d/www.conf

listen=/var/run/php7.2-fpm.sock

for

listen=127.0.0.1:9000

Now i view a 500 error page in WebUI

Now The error.log result:

[Fri May 17 12:02:45.613004 2019] [proxy_fcgi:error] [pid 123746] [client 192.168.5.144:55354] AH01071: Got error 'PHP message: PHP Fatal error:  Uncaught Exception: Missing one or more extensions. in /var/www/fog/commons/init.php:394\nStack trace:\n#0 /var/www/fog/commons/init.php(265): Initiator::_extCheck()\n#1 /var/www/fog/commons/base.inc.php(48): Initiator::startInit()\n#2 /var/www/fog/service/getversion.php(30): require('/var/www/fog/co...')\n#3 {main}\n  thrown in /var/www/fog/commons/init.php on line 394\n'

This tells me that php-fpm isn’t running or you have a firewall rule blocking connectivity.

Apache should communicate with php-fpm over that loopback network connection on port 9000. The first thing I would check (after resetting anything you changed and rebooting the fog server) is if php-fpm is running in memory with ps aux|grep php-fpm You should see the php-fpm process running. If it is running, then issue the following command to see if it’s listening where it should be netstat -an|grep 9000. That should return a line. If it is listening then we need to understand why apache isn’t communicating correctly.

I would also inspect the php-fpm logs in /var/logs. I have also seen where there was 2 versions of php-fpm installed and attempting to run where the system had php-fpm version 5 installed AND php-fpm version 7 with php version 7 installed. But php-fpm5 was configured to start. That was a mess to find and fix.
