PHP ne peut pas voir quelque chose dans son include_path

J'essaie d'exécuter PHPMailer sur mon serveur, mais j'ai du mal à faire en sorte que les pages web PHP le trouvent.

Si je cours php -f send_mail.php ça marche très bien, mais quand je fais des boucles example.myserver.com/send_mail.php J'obtiens l'erreur suivante :

Warning: require(PHPMailer/src/Exception.php): failed to open stream: No such file or directory in /var/www/html/send_mail.php on line 10

Fatal error: require(): Failed opening required 'PHPMailer/src/Exception.php' (include_path='.:/usr/share/pear:/usr/share/php') in /var/www/html/send_mail.php on line 10

Je note dans l'erreur ci-dessus que le chemin d'inclusion semble être '.:/usr/share/pear:/usr/share/php' même si en /etc/php.ini J'ai la ligne include_path = ".:/usr/share/pear:/usr/share/php:/php/includes" . J'ai aussi couru phpinfo() pour vérifier que /etc/php.ini était lu par l'interprète, et tout semble aller bien ici.

Dans tous les cas, le PHPMailer se trouve dans le dossier include_path cité dans l'erreur, donc il devrait le voir de toute façon.

[me@server ~]$ ls /usr/share/php/PHPMailer/
changelog.md  composer.json  examples             language  phpdoc.dist.xml  SECURITY.md  test                     UPGRADING.md
COMMITMENT    docs           get_oauth_token.php  LICENSE   README.md        src          travis.phpunit.xml.dist  VERSION

Une idée de ce que je pourrais manquer pour obtenir PHPMailer visible sur mes pages web PHP ?

EDIT : J'ai aussi vu este mais le problème ici semble être lié à une barre oblique inverse en tête du chemin d'accès donné à require ce qui n'est pas mon problème.

EDIT 2 : J'ai ajouté ma configuration Apache ci-dessous. Je ne suis pas très familier avec les serveurs web, donc je ne suis pas sûr que cela réponde à la question de @TeroKilkanen "Quelle est la configuration de votre serveur web ?". Faites-moi savoir si ce n'est pas le cas et j'essaierai d'en trouver d'autres.

#
# This is the main Apache HTTP server configuration file.  It contains the
# configuration directives that give the server its instructions.
# See <URL:http://httpd.apache.org/docs/2.4/> for detailed information.
# In particular, see 
# <URL:http://httpd.apache.org/docs/2.4/mod/directives.html>
# for a discussion of each configuration directive.
#
# See the httpd.conf(5) man page for more information on this configuration,
# and httpd.service(8) on using and configuring the httpd service.
#
# Do NOT simply read the instructions in here without understanding
# what they do.  They're here only as hints or reminders.  If you are unsure
# consult the online docs. You have been warned.  
#
# Configuration and logfile names: If the filenames you specify for many
# of the server's control files begin with "/" (or "drive:/" for Win32), the
# server will use that explicit path.  If the filenames do *not* begin
# with "/", the value of ServerRoot is prepended -- so 'log/access_log'
# with ServerRoot set to '/www' will be interpreted by the
# server as '/www/log/access_log', where as '/log/access_log' will be
# interpreted as '/log/access_log'.

#
# ServerRoot: The top of the directory tree under which the server's
# configuration, error, and log files are kept.
#
# Do not add a slash at the end of the directory path.  If you point
# ServerRoot at a non-local disk, be sure to specify a local disk on the
# Mutex directive, if file-based mutexes are used.  If you wish to share the
# same ServerRoot for multiple httpd daemons, you will need to change at
# least PidFile.
#
ServerRoot "/etc/httpd"

#
# Listen: Allows you to bind Apache to specific IP addresses and/or
# ports, instead of the default. See also the <VirtualHost>
# directive.
#
# Change this to Listen on specific IP addresses as shown below to 
# prevent Apache from glomming onto all bound IP addresses.
#
#Listen 12.34.56.78:80
Listen 80

#
# Dynamic Shared Object (DSO) Support
#
# To be able to use the functionality of a module which was built as a DSO you
# have to place corresponding `LoadModule' lines at this location so the
# directives contained in it are actually available _before_ they are used.
# Statically compiled modules (those listed by `httpd -l') do not need
# to be loaded here.
#
# Example:
# LoadModule foo_module modules/mod_foo.so
#
Include conf.modules.d/*.conf

#
# If you wish httpd to run as a different user or group, you must run
# httpd as root initially and it will switch.  
#
# User/Group: The name (or #number) of the user/group to run httpd as.
# It is usually good practice to create a dedicated user and group for
# running httpd, as with most system services.
#
User apache
Group apache

# 'Main' server configuration
#
# The directives in this section set up the values used by the 'main'
# server, which responds to any requests that aren't handled by a
# <VirtualHost> definition.  These values also provide defaults for
# any <VirtualHost> containers you may define later in the file.
#
# All of these directives may appear inside <VirtualHost> containers,
# in which case these default settings will be overridden for the
# virtual host being defined.
#

#
# ServerAdmin: Your address, where problems with the server should be
# e-mailed.  This address appears on some server-generated pages, such
# as error documents.  e.g. admin@your-domain.com
#
ServerAdmin root@localhost

#
# ServerName gives the name and port that the server uses to identify itself.
# This can often be determined automatically, but we recommend you specify
# it explicitly to prevent problems during startup.
#
# If your host doesn't have a registered DNS name, enter its IP address here.
#
#ServerName www.example.com:80

#
# Deny access to the entirety of your server's filesystem. You must
# explicitly permit access to web content directories in other 
# <Directory> blocks below.
#
<Directory />
    AllowOverride none

</Directory>

#
# Note that from this point forward you must specifically allow
# particular features to be enabled - so if something's not working as
# you might expect, make sure that you have specifically enabled it
# below.
#

#
# DocumentRoot: The directory out of which you will serve your
# documents. By default, all requests are taken from this directory, but
# symbolic links and aliases may be used to point to other locations.

# Relax access to content within /var/www.

    # Note that "MultiViews" must be named *explicitly* --- "Options All"
    # doesn't give it to you.

EDIT 3 : Selon la suggestion de @MichaelHampton, j'ai fouillé dans le journal d'audit du serveur, et j'ai trouvé ces lignes lorsque j'ai fait un appel à la page web.

Cela semble indiquer des erreurs d'autorisation, ce que je soupçonnais, mais que je n'arrivais pas à résoudre. J'ai essayé d'utiliser les instructions dans cette question . Maintenant, je n'obtiens rien dans le journal d'audit, mais je vois toujours l'erreur.

SELinux a bloqué le chargement de certains fichiers par PHP dans le répertoire /usr/share/php parce qu'ils ont les mauvais contextes. Il est fort probable qu'ils aient été déplacés d'un répertoire sans contexte SELinux par défaut, car le type était default_t . (Vous devez toujours copier les fichiers sur un système SELinux et supprimer les originaux, ou utiliser la fonction mv -Z .)

Vous pouvez résoudre le problème en définissant les contextes de fichiers corrects pour permettre au serveur web de lire les fichiers.

restorecon -rv /usr/share/php

À l'avenir, n'oubliez pas de copier les fichiers et de supprimer les originaux, ou utilisez la fonction mv -Z pour s'assurer que les contextes SELinux sont correctement définis.


Interpréter le journal d'audit :

  • PROCTITLE donne le nom du processus concerné. Notez qu'il est en hexadécimal et doit être décodé. Dans ce cas, il est décodé en php-fpm: pool www .
  • SYSCALL donne une variété d'informations, y compris l'appel système qui a été tenté, s'il a réussi, le nom du processus, uid/gid, et plus encore. Dans ce cas, un appel à lstat() (6) retourné errno 13, Permission denied .
  • AVC donne des informations sur le refus SELinux, y compris ce qui a été refusé et le nom du processus, le nom du fichier et les contextes impliqués. Ici, nous voyons que la permission getattr qui est nécessaire pour appeler lstat() a été refusée. Le contexte source est celui du programme, php-fpm qui a été httpd_t . Il a essayé d'accéder à un fichier de type default_t ce qui n'est pas autorisé. Et cela montre que SELinux est en mode d'application, et non en mode permissif.
