site web d'administration fonctionnel (mais mon serveur est vide d'inventaire)
SSL OK sur interface site web d'administration

Qu'ai je manqué ? J'ai lu à plusieurs reprise que l'erreur 500 était liée à un soucis de mot de passe MySQL, et j'ai pourtant vérifié ce point...

Did I miss something ? I read several times that Error 500 is due to problem with MySQL password but I've checked that...

Bonjour,

En désactivant SSL, as-tu les mêmes erreurs?

Bonjour,
Petit update de mon problème. Après une revue méticuleuse de mes fichiers de conf et autres php.ini... , j'ai tenté les manipulations suivante, hélas infructueuse (remontée d'erreur identique):

  1. Remplacer l'utilisateur MySQL par le root MySQL
  2. Enlever le SSL.

De plus, j'ai aussi vérifié que :

  1. mettre un mauvais user MySQL ou un mauvais nom de server MySQL changeait la séquence d'erreur.
  2. mod_perl était bien chargé (confimé par phpinfo() et par la manip décrite ici : http://ask.ocsinventory-ng.org/1280/agent-cant-comunicate-with-server-404?show=1280#q1280 )
  3. Faire un import local abouti à une erreur 400 : Error HTTP/1.1 400 Bad Request

Si vous avez un début d'idée ou de piste à suivre, ne vous gêner pas de me les suggérer.

Cordialement,
Bexounet

Hello,

small update of my problem. After a control of my conf files and php.ini... I have tested these operations, but with failure (same error sequence)

  1. replace MySQL user with the "root" MySQL account
  2. disable SSL.

And, I also checked that :

  1. use a bad MySQL credential or a bad MySQL server name change the error sequence
  2. mod_perl is loaded (confimed with phpinfo() and with the operation describe here: http://ask.ocsinventory-ng.org/1280/agent-cant-comunicate-with-server-404?show=1280#q1280 )
  3. A local import end with a error 400 : Error HTTP/1.1 400 Bad Request

If have an idea or just the beginning of idea about this problem, don't hesitate to say it.

Regards,
Bexounet

Bonjour,
2eme petit update de mon problème.

Pour simplifier la configuration, j'ai maintenant :

  1. Remplacer l'utilisateur MySQL par le root MySQL
  2. Enlever le SSL.

La séquence d'erreur est la même.

Par contre, faire un import local importe bien l'inventaire mais termine sur une erreur 500 : Error HTTP/1.1 500 Internal Server Error

Je n'arrive pas me souvenir comment j'ai eu cette erreur 400 lors de l'import local.

Cordialement,
Bexounet

Hello,

second small update of my problem.

To simplify my configuration, I have :

  1. replace MySQL user with the "root" MySQL account
  2. disable SSL.

The error sequence is still the same.
But, a local import successfully import the inventory but end with a error 500 : Error HTTP/1.1 500 Internal Server Error
I don't remember how I have got the previous error 400 on local import.

I have the same error "$r->print can't be called before the response phase at /usr/local/share/perl/5.14.2/Apache/Ocsinventory/Server/Communication.pm line 170.\n"

 

Did you find any resolution to this?

by (490 points)
For me, downgrading to mod_perl 2.0.8 instead of 2.0.9 fixed this.
by (490 points)
Thank you very much for this information. I still have the problem.
I will check that solution.

Regards,
Bexounet.
