Subject: some config issue with Apple supplied Tomcat
Date: Mon, 12 Jan 2009 16:26:47 -0500

Hi,

I am trying to setup a cluster using Apple supplied Apache2 and =20
Tomcat.  On OSX, tomcat is in /Library/Tomcat.

Apache is configured in a mixed way, because Apple installs 1.3 and =20
2.2, so there is /etc/httpd for config of 1.3 and /etc/apache2 for =20
config of 2.2.  However even the config file in /etc/apache2 refers to =20=

the workers.properties in /etc/httpd :)  Looks like as siamese twins =20
in the process of separation.

Tomcat version 6.0.18

Java:
java version "1.5.0_16"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_16-=20
b06-284)
Java HotSpot(TM) Server VM (build 1.5.0_16-133, mixed mode)

apache2:  version 2.2

Tomcat is running after checking the checkbox and restarting Apache2
pathsrv1:httpd administrator$ ps -avx |grep tomcat
59195 Ss     0:01.10   0   0      0   600172    628     -        0   =20
0.0  0.0 /bin/sh /Library/Tomcat/bin/tomcat-launchd.sh
62573 R+     0:00.00   0   0      0   590472     92     -        0   =20
0.0  0.0 grep tomcat

and I can get to the SessionExample via port 80.

However I get this into the mod_jk.log:
[Mon Jan 12 14:57:31 2009] [59281:0000] [error] init_jk::mod_jk.c =20
(2701): Initializing shm:/usr/logs/jk-runtime-status.59281 errno=3D2. =20=

Load balancing workers will not function properly.

Looking on the Internet someone recommended to create a "run" =20
directory, that used to be in /usr/local/apache2/.  I do not know if =20
that is the solution for this Apple supplied config on OSx 10.5.6.


I also have a second issue, but that might relate to this message =20
above.  I created a reverse proxy setup and this is what Apple put =20
into the site configuration file:

         <IfModule mod_proxy_balancer.c>
                 ProxyPass /apps/ balancer://balancer-group/ =20
stickysession=3DJSESSIONID
                 ProxyPassReverse /apps/ balancer://balancer-group/
                 <Proxy "balancer://balancer-group">
                         BalancerMember http://pathsrv1.yalepath.org =20
loadfactor=3D1
                 </Proxy>
         </IfModule>

Right now I have just one machine and I am trying it as a Balance =20
member and also as a reverse proxy.  So based upon the config, I =20
thought that if I want to go to;

=
http://pathsrv1.yalepath.org/apps/examples/servlets/servlet/SessionExample=


than the reverse proxy that is pathsrv1 will pass it to the balance =20
member, that is again pathsrv1 and from there It will give me the =20
SessionExample as if I would have gone just to

http://pathsrv1.yalepath.org/examples/servlets/servlet/SessionExample

Either my config is not right, or my thinking :)

Any good hint is appreciated.

J=E1nos
