Apache2, Tomcat5 and mod_jk2 configuration problems
Greetings,
I have a problem. I am trying to get Tomcat (5.0.25), Apache (2.0.49) and
mod_jk2 (2.0.4) all to talk to each other under RedHat 9.0.
So far I can get Apache up and working on port 80 and Tomcat works fine on
port 8080. However, my users want to be able to use .jsp pages on their
virtual hosts.
I did have it working fine on the old machine we had (Redhat 7.3, Apache
1.3, Tomcat 4 and mod_jk) but we upgraded and now its not working.
One thing I have noticed is when Tomcat starts up there is the message:
INFO: APR not loaded, disabling jni components: java.io.IOException:
java.lang.UnsatisfiedLinkError: /usr/local/httpd-2.0.49/modules/jkjni.so:
/usr/local/httpd-2.0.49/modules/jkjni.so: undefined symbol: apr_md5_final
I assumed I was getting this because Apache was not compilied in with apr
support, so I recompiled it with --with-apr and --with-apr-util. Apache
still works, but when I tried to recompile mod_jk2 it tells me now that my
apxs can not be found, even though prior it was finding it ok and its quite
clearly in the location specified.
I'm not sure if that is a critical error or not or how to overcome it. I
have been trying different compile options, but still not getting much luck.
When you click on a .jsp page, all that happens is the browser just sits
there continually loading. In the tomcat logs you get a line which says
"INFO: No next" and thats it.
Can anyone shed some light on my problem, before I do physical harm to the
box in question. The configuration files are as follows: Also, can I
have .jsp files enabled for some virtual servers and not for others, or is
it an all or nothing affair?

You can also enable an SSL HTTP/1.1 Connector on port 8443 by
following the instructions below and uncommenting the second
Connector
entry. SSL support requires the following steps (see the SSL Config
HOWTO in the Tomcat 5 documentation bundle for more detailed
instructions):
* If your JDK version 1.3 or prior, download and install JSSE
1.0.2 or
later, and put the JAR files into "$JAVA_HOME/jre/lib/ext".
* Execute:
%JAVA_HOME%\bin\keytool -genkey -alias tomcat -keyalg RSA

$JAVA_HOME/bin/keytool -genkey -alias tomcat -keyalg RSA (Unix)
with a password value of "changeit" for both the certificate and
the keystore itself.
By default, DNS lookups are enabled when a web application calls
request.getRemoteHost(). This can have an adverse impact on
performance, so you can disable it by setting the
"enableLookups" attribute to "false". When DNS lookups are disabled,
request.getRemoteHost() will return the String version of the
IP address of the remote client.

<!-- Defines a cluster for this node,
By defining this element, means that every manager will be
changed.
So when running a cluster, only make sure that you have
webapps in there
that need to be clustered and remove the other ones.
A cluster has the following parameters:
className = the fully qualified name of the cluster class
name = a descriptive name for your cluster, can be anything
debug = the debug level, higher means more output
mcastAddr = the multicast address, has to be the same for all
the nodes
mcastPort = the multicast port, has to be the same for all
the nodes
mcastBindAddr = bind the multicast socket to a specific address
mcastTTL = the multicast TTL if you want to limit your broadcast
mcastSoTimeout = the multicast readtimeout
mcastFrequency = the number of milliseconds in between
sending a "I'm alive" heartbeat
mcastDropTime = the number a milliseconds before a node is
considered "dead" if no heartbeat is received
tcpThreadCount = the number of threads to handle incoming
replication requests, optimal would be the same amount of threads as nodes
tcpListenAddress = the listen address (bind address) for TCP
cluster request on this host,
in case of multiple ethernet cards.
auto means that address becomes
InetAddress.getLocalHost().getHostAddress()
tcpListenPort = the tcp listen port
tcpSelectorTimeout = the timeout (ms) for the
Selector.select() method in case the OS
has a wakup bug in java.nio. Set to 0
for no timeout
printToScreen = true means that managers will also print to
std.out
expireSessionsOnShutdown = true means that
useDirtyFlag = true means that we only replicate a session
after setAttribute,removeAttribute has been called.
false means to replicate the session after
each request.
false means that replication would work for
the following piece of code:
<%
HashMap map =
(HashMap)session.getAttribute("map");
map.put("key","value");
%>
replicationMode = can be either 'pooled', 'synchronous' or
'asynchronous'.
* Pooled means that the replication happens
using several sockets in a synchronous way. Ie, the data gets replicated,
then the request return. This is the same as the 'synchronous' setting
except it uses a pool of sockets, hence it is multithreaded. This is the
fastest and safest configuration. To use this, also increase the nr of tcp
threads that you have dealing with replication.
* Synchronous means that the thread that
executes the request, is also the
thread the replicates the data to the other
nodes, and will not return until all
nodes have received the information.
* Asynchronous means that there is a
specific 'sender' thread for each cluster node,
so the request thread will queue the
replication request into a "smart" queue,
and then return to the client.
The "smart" queue is a queue where when a
session is added to the queue, and the same session
already exists in the queue from a previous
request, that session will be replaced
in the queue instead of replicating two
requests. This almost never happens, unless there is a
large network delay.
-->
<!--
When configuring for clustering, you also add in a valve to
catch all the requests
coming in, at the end of the request, the session may or may
not be replicated.
A session is replicated if and only if all the conditions are met:
1. useDirtyFlag is true or setAttribute or removeAttribute has
been called AND
2. a session exists (has been created)
3. the request is not trapped by the "filter" attribute
The filter attribute is to filter out requests that could not
modify the session,
hence we don't replicate the session after the end of this
request.
The filter is negative, ie, anything you put in the filter,
you mean to filter out,
ie, no replication will be done on requests that match one of
the filters.
The filter attribute is delimited by ;, so you can't escape
out ; even if you wanted to.
filter=".*\.gif;.*\.js;" means that we will not replicate the
session after requests with the URI
ending with .gif and .js are intercepted.

I just got it working. I had installed it from source, was a
library problem. Just writing up my documentation at the moment. I'll
send you a copy of that when I'm done.

As promised, here are my notes on installing mod_jk2 with Apache
2.0.49 and Tomcat 5.0.25. This is under RedHat 9.0 and the paths and
things are a straight cut and paste from my system here, so may not match
up for all accounts. Key problem I had was the libraries, once that was
figured out it was some minor typos in the configuration files, and then
its all up and going now.
Cheers,
Ryan.
Notes -->
mod_jk2 (tomcat connector)
Download mod_jk2
http://apache.ausgamers.com/jakarta/tomcat-connectors/jk2/source/jakarta-tomcat-connectors-jk2-2.0.4-src.tar.gz
Check the
http://apache.ausgamers.com/jakarta/tomcat-connectors/jk2/ page for
information/status on mod_jk2
Uncompress the archive
gzip -dc jakarta-tomcat-connectors-jk2-2.0.4-src.tar.gz |
tar -xvf -
Compile
cd to
/usr/local/src/jakarta-tomcat-connectors-jk2-2.0.4-src/jk/native2
./configure --with-apxs2=/usr/local/httpd/bin/apxs
--with-apr-lib=/usr/lib --with-tomcat-41=/usr/local/tomcat
--with-java-home=/usr/java/jdk --with-jni
edit ./server/apache2/Makefile
Find the block -->
ifdef APR_LIBDIR_LA
JK_LDFLAGS=-L${APACHE2_LIBDIR} -lcrypt
else
JK_LDFLAGS=-lcrypt ${APR_LIBS}
endif
And change it to this:
ifdef APR_LIBDIR_LA
JK_LDFLAGS=-L${APACHE2_LIBDIR} -lcrypt
else
JK_LDFLAGS=-lcrypt ${APR_LIBS}
JK_LDFLAGS=-lcrypt ${APR_LIBS} -L/usr/local/httpd-2.0.49/lib -laprutil-0
-lgdbm -ldb-4.0 -lexpat
endif
Note the extra LDFLAGS --> JK_LDFLAGS=-lcrypt ${APR_LIBS}
-L/usr/local/httpd-2.0.49/lib -laprutil-0 -lgdbm -ldb-4.0 -lexpat
To know what flags to add, run
apu-config --link-ld --libs
That will output something like
-L/usr/lib -laprutil-0 -lgdbm -lexpat
Then check the version of apu-config. I discovered that I
had two versions. One in
/usr/bin and another in /usr/local/httpd/bin/
/usr/bin/apu-config --link-ld --libs
-L/usr/lib -laprutil-0 -lgdbm -lexpat
/usr/local/httpd/bin/apu-config --link-ld --libs
-L/usr/local/httpd/bin -laprutil-0 -lgdbm
-ldb-4.2 -lexpat
When I tried adding the "-ldb-4.2" flag it didn't like it,
so I did a bit of a search and tried
-L/usr/local/httpd/bin -laprutil-0 -lgdbm
-ldb-4.0 -lexpat
instead which worked. (I think the path for db-4.2 may
need to be added to my /etc/ld.so.conf file?)
cd ../build/jk2/apache2
Run apxs
/usr/local/httpd/bin/apxs -n jk2 -i mod_jk2.so
Should see something like:
[root@projects apache2]# /usr/local/httpd/bin/apxs -n jk2

Re: Apache2, Tomcat5 and mod_jk2 configuration problems
Posted by Chong Yu Meng <ch...@cymulacrum.net>.
Hi Ryan,
I should have asked this earlier, but are you using the RPM version of
Apache or compiling the source tarball ? I notice that your directory is
/usr/local, which indicates that you are probably using the source
tarball (for RH9 rpms, it would be /etc/httpd).
If you are using the source tarball, there are a LOT of things that are
different. I believe you are missing a package, hence the gdbm error. I
cannot recall at the moment what the name of the package is -- can you
do a search on rpmfind ? Another thing: apxs is located inside
/usr/local/httpd-2.0.49 -- just do a "find /usr/local/httpd-2.0.49 -name
apxs" to locate it.
Did you do a Minimal install for Red Hat ? You will need to ensure that
you have the necessary packages installed. See this for a short list :
http://cymulacrum.net/writings/tomcat5/c875.html#JK2_INTEGRATION_SETUP
You probably don't need apr and apr-util because you installed Apache
from source.

pascal chong

Thanks for that. I gave that a whirl, putting in the extra
library and that solved the problem of the "undefined symbol apr_md5_final"
error, but now I'm getting the following error instead:
INFO: APR not loaded, disabling jni components: java.io.IOException:
java.lang.UnsatisfiedLinkError: /usr/local/httpd-2.0.49/modules/jkjni.so:
/usr/local/httpd-2.0.49/lib/libaprutil-0.so.0: undefined symbol: gdbm_errno
Which would appear that that linked library isn't correct.
Any hints?

tomcat crash ... "unexpected exception"
Posted by ba...@bpo.be.
Hi,
I have serious problems with my web aplpication (based on Apache/Tomcat), I'm a system guy
and I'd like at least to identify where the problem is situated: system, memory, db,
application itself, etc., but I'm not related at all to JSP or Java stuff ...
Well, here is my situation :
Apache 2.0.49 (compiled --with-mpm=worker)
Tomcat 4.1.30
mod_jk 2.0.2
Java SDK 1.4.2_02
Apache is configured to serve all requests (static) except .jsp which are transmitted to
tomcat through mod_jk2.
Here below is a copy of the error in catalina.out. Before the "unexpected exception" you
see client transactions, labeled with "ITS*", meaning clients navigate through
menus in the app, etc., then you see the exception, then somebody (huh ... me) restart all
the stuff and it continues with normal transactions ...
the error (sorry for length) :

(... transactions ...)
---------------------------------------------------------------------
At the same time in Apache error log, I see of course that it can't connect to ajp13
connector, which is obvious.
The transactional server (with DB) is another machine than the webserver.
Above I see "from space 35072K, 100% used". I don't know anything about how java is
managing his memory, but "100%" doesn't look good, isn't it ?
Anyway java runs with JAVA_OPTS=-Xms5120m -Xmx6144m, so it has more than 5Gb RAM to run !!
Do I have to look into apache/tomcat configuration ?
into the application code itself ?
both ?
I'm a bit lost ...
Any available help would be very appreciated.
Thanks,
Bastien.

Re: Apache2, Tomcat5 and mod_jk2 configuration problems
Posted by Chong Yu Meng <ch...@cymulacrum.net>.
Hi Ryan,
It sounds like an error similar to one Andrew Clute encountered on Red
Hat Enterprise Linux 3 (apr_md5_final). I transcribed some of the steps
he took here : http://cymulacrum.net/writings/tomcat5/a1375.html
Can you test it first ? If it works, I would like to add a comment to
the document that says that the steps apply to Red Hat 9 as well.

pascal chong
