Can't access web interface

[anndrew]

Hi all!

I'm trying to run ZoneMinder in my PC since I want to manage my IP camera through ZoneMinder. My operating system is Debian bookworm. I followed the instalation steps at https://wiki.zoneminder.com/Debian_12_B ... and_1.37.x, basically the suggested script in that website. So I now have ZoneMinder version 1.36.35~20241022.27-bookworm installed.

But I can't access the web interface via http://hostname_or_ip/zm. What I get is a text result in the browser, either in firefox or in chromium.

Here are some outputs in case it would help to narrow down my issue:

Description: video camera security and surveillance solution
 ZoneMinder is intended for use in single or multi-camera video security
 applications, including commercial or home CCTV, theft prevention and child
 or family member or home monitoring and other care scenarios. It
 supports capture, analysis, recording, and monitoring of video data coming
 from one or more video or network cameras attached to a Linux system.
 ZoneMinder also support web and semi-automatic control of Pan/Tilt/Zoom
 cameras using a variety of protocols. It is suitable for use as a home
 video security system and for commercial or professional video security
 and surveillance. It can also be integrated into a home automation system
 via X.10 or other protocols.

All the following commands yield correct outputs:

Code: Select all

sudo systemctl enable zoneminder
sudo service zoneminder start
sudo adduser www-data video
sudo a2enconf zoneminder
sudo a2enmod rewrite
sudo a2enmod headers
sudo a2enmod expires
sudo service apache2 reload

The text outputs when I try to access the web interface, in firefox, seems to correspond to the php file at: /usr/share/zoneminder/www/index.php. Here I attach a screenshot:



Here is the same in text format. It is shown as a long and continuos text:

Since the text starts at the line with the 'patter' typo, I followed this post viewtopic.php?t=33658 to change that typo from 'patter' to 'pattern', but I still get the text result in the web browser.


Following another post viewtopic.php?t=29382 I changed '#User=www-data' to 'User=www-data' (just removed the '#') in the file /lib/systemd/system/zoneminder.service. But it didn't help either.

I am not used to php language, nor the complexity of network systems. I looked at https://www.w3schools.com/php/php_mysql_intro.asp to read about the php syntax and the rest of the php file apparently seems ok.

The command: sudo systemctl status zoneminder.service seems to inform that everything is OK too (to me).

No clue why I can't access the web interface.

Any help would be much appreciated. Thanks.

The fundamental fault here seems to be that the web-server is doing the bare-minimum here ...

You asked to receive the contents of "something.php" and it served you, literally, the content of that file. Unprocessed.

Of course, what _should_ happen is that .php script _runs_ and the output from _that_ is served to you.

Seems a common problem outside of ZM too

Thank you mikb for your reply. That gives me new clues to continue searching...

In these two posts:
https://stackoverflow.com/questions/355 ... plain-text
https://unix.stackexchange.com/question ... trol-panel

they comment I would need the PHP libraries, either the libapache2-mod-php or the PHP 5 library for Apache. the first one is already installed but I don't have the second (PHP5) library available in my distro. But that was an old post at stackoverflow, so I guess the equivalent would be the libapache2-mod-php8.2 in my system. It was already installed.

I will continue searching for a way to make php scripts running in my web browser...

Thanks!

Hi again,

I found a similar issue here: viewtopic.php?t=10394

Following answers there, I made a PHP file at /usr/share/zoneminder/www/testing.php
containing just these three lines:

Code: Select all

<?PHP
phpinfo();
?>

It is supposed to give php information. When I try to run it from the web browser via: http://localhost/zm/testing.php nothing happens, just a blank page.

Following the same post, since I had not the zm folder /var/www/zm, I did:

Code: Select all

ln -s /usr/share/zoneminder /var/www/zm 

But it doesn't fix it either.

The url http://localhost/zm/index.php still gives the plain text commented earlier.

In case any of my searching or attemps could give someone any clue about my issue, I will be updating here any info/output I find that could help.

(Sorry if I am making this thread too long with rubish but, being a newbie with ZoneMinder and networks in general, I am at a point that can't tell what is important from what is not.)

When I write this in the mozilla web browser:

Code: Select all

http://localhost:80

I get the Apache2 Debian Default Page saying "it works!". Here is a screenshot:



So at least I know apache2 is not the problem... :/

Here is the output of php -v:

Update.
I have read in this post https://stackoverflow.com/questions/512 ... ource-code that in order for apache to open php at web browsers apache's httpd.conf file should have the PHP MIME type in it. Some line similar to:

Code: Select all

AddType application/x-httpd-php .php

I have checked that my /etc/apache2/apache2.conf doesn't contain any reference to AddType or php at all. So there I go and added it at the end of the file:

Code: Select all

AddType application/x-httpd-php .php

I restarted apache and php services and tried entering the ZoneMinder web interface, but no success yet. However I think I am getting closer, since now I get a file downloaded (it corresponds to the same file comment at the beginning of the post (/usr/share/zoneminder/www/index.php).

I also tried both with the original file /usr/share/zoneminder/www/index.php and with the corrected typo (patter / pattern). With both I get the file downloaded.

Please, any insights, or anything else I should try?

[iconnor]

sudo a2enmod php8.2
sudo systemctl reload apache2

[anndrew]

Thank you so much iconnor. Using your commands I finally got it!! Can't believe it!

Here is what I encountered:

I tried those two commands but initially got a 'conflict' message:

Code: Select all

$ sudo a2enmod php8.2
Considering dependency mpm_prefork for php8.2:
Considering conflict mpm_event for mpm_prefork:
ERROR: Module mpm_event is enabled - cannot proceed due to conflicts. It needs to be disabled first!
Considering conflict mpm_worker for mpm_prefork:
ERROR: Could not enable dependency mpm_prefork for php8.2, aborting

Following these post https://stackoverflow.com/questions/470 ... -php-files I run these commands:

Code: Select all

    sudo a2dismod mpm_event              # ===>  this went ok.
    sudo systemctl restart apache2       # Got an error: Job for apache2.service failed because the control process exited with error code, but I ignore it and continued.
    sudo a2enmod mpm_prefork             # ===>  this went ok.
    sudo systemctl restart apache2       # ===>  this went ok.
    sudo a2enmod php8.2                  # ===>  this went ok.
    sudo systemctl restart apache2       # ===>  this went ok.

After that I could enter the web interface!

Here, a screenshot to show the initial web interface appearance, with the privacy statements.


And the ZoneMinder interface:


I can now start learning about ZoneMinder.
