PHP warnings

[Rico29]

Hello I installed your adapted weathermap in centreon, using php8.1

problem is that the created service "weathermap poller" calls the following command using centreon-engine user :

php /usr/share/centreon/www/modules/centreon-weathermap/php/../poller.php

which results in errors :

# sudo -u centreon-engine php  /usr/share/centreon/www/modules/centreon-weathermap/php/../poller.php
PHP Warning:  require(/etc/centreon/centreon.conf.php): Failed to open stream: Permission denied in /usr/share/centreon/config/centreon.config.php on line 40

/usr/share/centreon/config/centreon.config.php tried to include : require _CENTREONETC . '/centreon.conf.php';

so I've set-up a crontab qhich generates the output images

# tail /etc/cron.d/centreon -n2

# Cron for weathermaps generation
*/2 * * * * root php  /usr/share/centreon/www/modules/centreon-weathermap/php/../poller.php

but I still have warnings like :

PHP Deprecated:  Implicit conversion from float 84.5 to int loses precision in /usr/share/centreon/www/modules/centreon-weathermap/src/lib/WeatherMapNode.class.php on line 640

Hi @Rico29, seems your poller.php has not enough permissions to reach centreon.conf.php which grants weathermap access to the database. You may try to increase it using chmod, also, ensure these directories have write permission:

/usr/share/centreon/www/modules/centreon-weathermap/src/configs
/usr/share/centreon/www/modules/centreon-weathermap/src/output
/usr/share/centreon/www/modules/centreon-weathermap/src/images

you may ignore those deprecated warnings or omit them, prepending a @ operator

let me know if you managed to fix it by changing permissions

Hello, I'm getting the same error messages as Rico29. I've made sure that these directories have write permissions /usr/share/centreon/www/modules/centreon-weathermap/src/configs /usr/share/centreon/www/modules/centreon-weathermap/src/output /usr/share/centreon/www/modules/centreon-weathermap/src/images

[kozfelipe]

hi @Tolkyen, have you ensure centreon-engine is the owner of output directory?

[Tolkyen]

Yes, this is the current setting

[kozfelipe]

@Tolkyen can you show how are permission settings for poller.php?

• I just removed my module and re-download it from this repo

• and I ran the following:

sudo chown -R apache:apache /usr/share/centreon/www/modules/centreon-weathermap/ chown -R centreon-engine:apache /usr/share/centreon/www/modules/centreon-weathermap/src/output/ chmod 777 /usr/share/centreon/www/modules/centreon-weathermap/poller.php

• reactivated the module from extension manager

• and ran sudo -u centreon-engine /usr/share/centreon/www/modules/centreon-weathermap/poller.php

I got the following output without errors: 2024-03-04 18:48 - 0 processed

can you confirm these steps?

I used php 8.1.12 -rw-r--r-- 1 apache apache /etc/centreon/centreon.conf.php

[Tolkyen]

Hi @kozfelipe, I followed your instructions. I've found the reason for the error: you need to add read access for others to the /etc/centreon/centreon.conf.php file.. This is less secure than what the centreon documentation recommends (https://docs.centreon.com/docs/23.04/administration/secure-platform/#securing-configuration-files).

Thank you for your help.

Very well, I'm glad you made it
