Bonjour,

Je cherche à atteindre un serveur tomcat qui n'est pas en DMZ, pour cela je passe par un serveur apache 2.4 installé sur un debian 8, n'arrivant pas à résoudre mon problème l'erreur exacte est : Bad Gateway : The proxy server received an invalid response from an upstream server.

J'ai tenté en vain de simplifier la configuration au maximum pour tester c'est à dire:
- Utilisation de l'application sample (cf https://tomcat.apache.org/tomcat-8.0-doc/appdev/sample/ ).
- Les serveur tomcat et apache sont sur la même machin (et tous 2 fonctionnelle).

Pour cela je passe par le VirtualHost suivant (épuré au maximum pour essayer de comprendre où été le problème):

Code :

<VirtualHost X.X.X.X:80>
        ServerName monprojet.me
        JkMount /sample/* worker1 
</VirtualHost>

J'ai configuré mon jk.load au minimum vitale et je n'est pas touché au jk.conf:

JkLogFile /var/log/apache2/mod_jk.log
JkLogLevel debug
JkLogStampFormat "[%a %b %d %H:%M:%S %Y] "

Voici mon workers.properties:

J'ai sans doute oublié quelque chose mais je ne sais pas où...

Merci d'avance de votre aide.

Re bonjour,

J'ai finalement résolue mon problème en passant par la commande ProxyPass et ProxyPassReverse je suis pas certain que ce soit plus propre mais au moins ça fonctionne.

Cordialement.
