Apache mod_jk

[Daniel Mróz]

Czesc

   Mam maly problemik. Musze polaczyc Apache z Tomcatem. Apache
chodzi, Tomcat rowniez, z osobna jest wszystko OK. Teraz, biore modul
mod_jk (EAPI) ze strony indianca (w dystrybucji nie ma), tworze
workers.properties:

----------------------------------------------
workers.java_home = /usr/local
workers.tomcat_home = /home/users/tomcat

worker.list = ajp13

worker.ajp13.type = ajp13
worker.ajp13.host = localhost
worker.ajp13.port = 8009
----------------------------------------------

Konfiguruje Tomcata:

----------------------------------------------
<!-- Define a Coyote/JK2 AJP 1.3 Connector on port 8009 -->

<Connector className="org.apache.coyote.tomcat4.CoyoteConnector"
   port="8009" minProcessors="5" maxProcessors="75"
   enableLookups="true" redirectPort="8443"
   acceptCount="10" debug="0" connectionTimeout="20000"
   useURIValidationHack="false"
   protocolHandlerClassName="org.apache.jk.server.JkCoyoteHandler"/>
----------------------------------------------

Konfiguruje Apache:

----------------------------------------------
LoadModule jk_module          lib/apache/mod_jk.so
AddModule mod_jk.c

JkWorkersFile /etc/httpd/workers.properties
JkLogFile /var/log/httpd/mod_jk.log
JkLogLevel debug
JkLogStampFormat "[%a %b %d %H:%M:%S %Y] "
JkOptions -ForwardKeySize +ForwardURICompat +ForwardDirectories
JkRequestLogFormat "%w %V %T"

JkMount /examples/servlets/* ajp13
---------------------------------------------

Odpalam Tomcata, ktory otwiera sobie port:

---------------------------------------------
[root w hanako root]# netstat -nl | grep 8009
tcp        0      0 0.0.0.0:8009            0.0.0.0:*   LISTEN
---------------------------------------------

Odpalam Apache, ktory nie zglasza zadnych bledow podczas ladowania
modulu (napewno jest ladowany), a jedyne co mam w logach, to w
mod_jk.log (wycialem timestampy):

-------------------------------------------------

(skad on do cholery bierze workera ajp12?)
Niestety, kazda proba wywolania jakiegokolwiek pliku z
http://127.0.0.1/examples/servlets/ konczy sie bledem 500 (Internal
server error), a Apache wogole nie nawiazuje zadnego polaczenia
Tomcatem wiszacym na 8009. Log z sesji w mod_jk.log:

-------------------------------------------------

------------------------------------------------

Teraz pytania:
- czy ktos z Was mial z czyms takim do czynienia?
- czy w PLD jest jakis sposob na polaczenie Apache z Tomcatem?
- dlaczego w PLD nie ma apache-mod_jk?


Dziekuje za pomoc i pozdrawiam
