how to make sure that apache and tomcat servers talkin to each other

What do you mean by 'Talking to each other'? Are they setup as tomcat workers through apache? Or do you just want to know if it can access the other server?

If it's access you want, you should be able to telnet from the apache server to the host and port that you have tomcat listening on to see if the one server can access the other.

telnet tomcat.domain.com 8080

Select allOpen in new window

If it's setup as a worker, when you restart apache, you should see some sort of error in either the error_log or the worker_log for apache.

Here is the details..have 3 servers

A - Apache Server Httpd - having redhat 5.6
B - Tomcat Server having redhat 5.6
C Database server having Mysql on it

I want to check whether server A is able to connect to server B or not..

User = abc
Port = 8009

so what i need to do now ..
some more logs from server B

-->from /usr/local/tomcat/logs/catalina.date.log
 org.apache.jk.commom.ChannelSocket processConnection
SEVERE : BAD Packet signature 18245
SEVERE:Error ,Processing Connection
Plss advice

I still don't really understand what apache's role is in this setup. Is it some sort of proxy or something?

I would restart tomcat. Does it show any errors in the catalina.out when starting?

I guess you are using mod_jk to configure apache and tomcat?

You probably should post your apache configuration/ mod_jk's worker.properties file.

for work.proerties configuration, normally it has a host and a port like this:

worker.tomcat4.type=ajp13
worker.tomcat4.host=hostname
worker.tomcat4.port=8009

I am not sure why you have a "user =abc" here.

You can try "telnet tomcathost 8009" from the apache server , see if you have a network problem first.

Hi Jack , you are right m using mod_jk to configure

ok i have tried it and it shows
Trying 192.x.x.x
Connected to hostname

from both Tomcat server and apache server (note i have seperate server for Apache n tomcat n hardware too)

My application first connect to Apache server than apache server sent request with port 8009 to tomcat server...

just want to know what else i can verify to check all is working?

You have to add JkMount to your httpd.conf and to check the connection is working
for example you add
JkMount /test loadbalancer0  [ loadbalancer0 will be in worker.properties]

go to your browser and hit http://apacheserver/test
and you should see an error from tomcat server
this should be the same if you do http://tomcatserver:8080/test

Here are  the new error logs in /etc/httpd/logs/mod_jk.log

above logs are coming when i am trying to telnet with 8009 port...plss help

Can you paste here
Apache: htttp.conf workers.properties
tomcat server.xml

Plss chk attachements httpd.txt
mod-jk.conf.txt
server.xml
worker.properties.txt

add jvmRoute to server.xml

<Engine name="Catalina" defaultHost="localhost">

Select allOpen in new window

as

<Engine name="Catalina" defaultHost="localhost" jvmRoute="ajp13w" >

Select allOpen in new window

in mod-jk.conf
change

JkWorkerProperty worker.ajp13w.host=hostname

Select allOpen in new window

to

JkWorkerProperty worker.ajp13w.host=ipaddress of tomcat server

Select allOpen in new window

if you want to use worker.properties you need to add this to you httpd.conf

JkWorkersFile "conf/workers.properties"

Select allOpen in new window

I am not sure if all that can be in mod-jk.conf but you can give it a try.

thank u so much ..i have changed and its better but not sucessfully running ...

Please advice our suggest...m tottaly fed up with this :(

How are you trying to start tomcat ?
startup.sh

is the JAVA_HOME variable set to correct location in that file?

i dnt know much abt tomcat ....i ma using service tomcat restart and JAVA_HOME variable where to confirm the file and location?

Look at  /etc/init.d/tomcat and you will find the location or the file which has that in there

/usr/local/tomcat/bin could also be a good location to look at

i found it  and run it but still same logs ....could you please guide me how to cross check that servers communicationg with each other

try also to put the following in context.xml in tomcat/conf instead on server.xml

<Resource name="jdbc/dtsrwDataSource" username="dtsappuser" password="newpass" url="jdbc:mysql://mysql:3306/dts" type="javax.sql.DataSource" factory="org.apache.commons.dbcp.BasicDataSourceFactory" driverClassName="com.mysql.jdbc.Driver" maxIdle="2" maxActive="4" maxWait="11000" validationQuery="SELECT 2" testWhileIdle="true" timeBetweenEvictionRunsMillis="10000" testOnBorrow="false" minEvictableIdleTimeMillis="60000"/>
<!--

Select allOpen in new window

Server communication setup test is easy

put
JkMount /jkstatus* jkstatus in httpd.conf that ang go to http://httpserver/jkstatus to see some info

also you can try
JkMount /test* ajp13w

and if you go to http://httpserver/test  you should see the same page as
http://tomcatserver:8080/test

If you see the same then the communication with apache and tomcat is working fine.

Before you do that you have to see if tomcat has started without any errors by itself.

Also looks like the HTTP container for tomcat is missing to do the above test add the following to tomcat after <Service name="Catilina">

<Connector port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />

Select allOpen in new window

you mean to say remove server.xml and put context?

No add context.xml along with server.xml and move the Dataresources to context.xml.

but before that did you try the communication ?

i have tried to test but both test failed ..no welcome page open on both server..

on web server when i m running curl http://tomcatservername:8009 
it shows curl: (52) Empty reply from server

and same on tomcat server

when i put ur connector for http it shows parse fatal error during service restart ...open quote expected for attribute "redirectPort" associated with element type "Connector"

on webserver try curl http://apache:apacheport/test   [example http://192.168.1.100/test]

port 8009 speaks AJP not HTTP

I am assuming you want to setup User <--> Apache <--> Tomcat<-->mysql

so you as a user hit apache not tomcat directly.

I tried but that is not working showing /test not found ..and when m running http://hostnamewebserver it shows welcome page .../test is the partiton on my mysql backen server which is mounted on tomcat server with nfs  

you r right i want to contact it tomcat server through a web servers..

my application first go to webserver than webserver connect to tomcat and tomcat connect to mysql server for database n all...and /test or /dts is the partition which is on mysql server mounted on tomcat server as /dts

Can you give me the output of the curl

change test to any text rename it as tomcatUthere does not matter what you should get is something similar to the following. If you get this then your communication from apache to tomcat is working fine.

<html><head><title>Apache Tomcat/6.0.14 - Error report</title><style><!--H1 {font-family:Tahoma,Arial,sans-serif;color:white;background-color:#525D76;font-size:22px;} H2 {font-family:Tahoma,Arial,sans-serif;color:white;background-color:#525D76;font-size:16px;} H3 {font-family:Tahoma,Arial,sans-serif;color:white;background-color:#525D76;font-size:14px;} BODY {font-family:Tahoma,Arial,sans-serif;color:black;background-color:white;} B {font-family:Tahoma,Arial,sans-serif;color:white;background-color:#525D76;} P {font-family:Tahoma,Arial,sans-serif;background:white;color:black;font-size:12px;}A {color : black;}A.name {color : black;}HR {color : #525D76;}--></style> </head><body><h1>HTTP Status 404 - /tomcatUthere</h1><HR size="1" noshade="noshade"><p><b>type</b> Status report</p><p><b>message</b> <u>/tomcatUthere</u></p><p><b>description</b> <u>The requested resource (/tomcatUthere) is not available.</u></p><HR size="1" noshade="noshade"><h3>Apache Tomcat/6.0.14</h3></body></html>

Select allOpen in new window

The test is to get the not found response from tomcat. If you get it from apache then the communication is not working but if you get the not found from tomcat then tomcat and apache are talking to each other

m sorry ..where n which file u want me to edit for test ..can i create new txt file on web server?plss explain

in mod_jk.conf of apache conf.d folder add JkMount /test* ajp13w at the end of the file
restart apache

curl http://apache/test

give me the output here .

I have tried with webserver ip and hostname both this is the reply

curl http://192.168.x.x/test

the curl test shows that the apache to tomcat connection for ajp is not working

can you paste here the new conf files

at the end of mod-jk file add

JkMount /coolcap* ajp13w

Select allOpen in new window

service httpd restart

please paste after restarting apache
curl http://apahceserver/coolcap

and give me the output here

it shows nothing no error no message jst return back to the shell..just show
#curl http://apacheserver/coolcap
#

but when i am running
curl http://apacheserver/coolcap/

than it shows following

sorry above logs are coming using dts not coolcap

i.e. dts/ and dts

for coolcap and coolcap/ it shows blank

Ok this shows that your AJP setup is correct just add the corresponding JkMount for your application in the mod-jk file

for example if you application is deployed in to tomcat with webapp folder expanding the war file as
tomcat/webapps/dtsapplication

then to publish that from apache you need to add

JkMount /dtsapplication* ajp13w

Select allOpen in new window

in your mod-jk file at the end and

service httpd restart

Looks like in your case just put at the end of mod-jk file and restart

JkMount /dts/* ajp13w

Select allOpen in new window

done as u said but same message


curl http://apacheserver/dtsapplication/

than it shows following
<html><head><title>Apache Tomcat/5.5.23 - Error report</title><style><!--H1 {font-family:Tahoma,Arial,sans-serif;color:white;background-color:#525D76;font-size:22px;} H2 {font-family:Tahoma,Arial,sans-serif;color:white;background-color:#525D76;font-size:16px;} H3 {font-family:Tahoma,Arial,sans-serif;color:white;background-color:#525D76;font-size:14px;} BODY {font-family:Tahoma,Arial,sans-serif;color:black;background-color:white;} B {font-family:Tahoma,Arial,sans-serif;color:white;background-color:#525D76;} P {font-family:Tahoma,Arial,sans-serif;background:white;color:black;font-size:12px;}A {color : black;}A.name {color : black;}HR {color : #525D76;}--></style> </head><body><h1>HTTP Status 404 - /dts/</h1><HR size="1" noshade="noshade"><p><b>type</b> Status report</p><p><b>message</b> <u>/dts/</u></p><p><b>description</b> <u>The requested resource (/dts/) is not available.</u></p><HR size="1" noshade="noshade"><h3>Apache Tomcat/

i think my webserver unable to reach or find that /dtsapplication folder on tomcat server ? if yes than what i can do in this?

coolcap are you using mod_jk / tomcat / apache for the first time ?

We have established that AJP setup is correct.

Now what do you want to do ?

how do you get to your application ?

is it a webservice etc? what is your test case what makes you think that your application is not working?

what you are getting is tomcat saying that that particular URL you are looking for is not served by the application.

Ask you application guys to test their app or you can test it if you know how.

also just to confirm
can you give the output of

ls webapps  from tomcat server (webapps is in tomcat installation folder)

we have a application that send n receive msgs and this application connect to webserver first than link to application/tomcat server and this server having a mount point called /dts which is actually located on our backend server having mysql.

when my application guys testing their code it shows this :
> DTS,280911 16:38:38,    SERVER poll,1,0, Connecting over primary server.
DTS,280911 16:38:39,    Send FAILED,1,404, HTTP error encountered on DTS handshake.
DTS,280911 16:38:39,       MBX POLL,0,0, Polling mailbox DTS.
DTS,280911 16:38:39,         UPLOAD,0,0, Uploading to mailbox.

ls webapps output:
dts dts.war
in #tomcat~ ls -lrt
>755 dtsuser:dtsgroup webapps

Can you try and ask them if they can get more logs from their app for
Send FAILED,1,404, HTTP error encountered on DTS handshake.

like what server they are hitting/ any more details on 404 error their requesting URI etc...

also just to confirm there is no typo
you have tried

curl http://apacheserver/dts/  above
NOT
curl http://apacheserer/dtsapplication which was an example right?

these are the ssl logs for DTS application
------------------------------------------------------

If I can give a guess, it can be something related to servelets being deployed or present on the server.

yes i m using the correct http link...not example one

One more thing is there any possibilty due to certificate issue this error can be come?
because the current certificate in /usr/share/ssl are not correct?

I think JAVA needs the certificate installed in the app/ trusted in the app I guess. Not sure but had one of our apps with this issue and they created their own SSL trusted module in the app

just want to make sure ..do i need to create new one on web server and tomcat server ..or application guy need to do that ..plss explain a bit ..my application guy will come on monday ..so will let u know more about this on monday ..thank you so much ....for ur great help ...if any thing u want to me do in servers i can do ..but for application related need to wait till monday

please let me know how u created that cerificate or what u did for ur apps..many thanks

Its all upto App guys now. I am not sure what our apps people have done exactly. And I am not a JAVA expert so cannot help much in that as far as server is concerned you should be good to go. They need to debug their app to make it work.

Good luck

Thank u ...one query..can i check that /dts folder is available from/or on  tomcat server ...so that we can surre of that there is no folder access issue ..?

Thank you so much Its working some how...Really appreciated.

Cheers

you can check /dts is working from tomcat if tomcat has the HTTP container. Look at the docs/ man as somebody has removed HTTP part from your tomcat dont know the reason.

Alternatively
if the /dts is visible from apache that is good enough as that is being served by tomcat.
