Hi,
I'm in need of a little help. I'm trying to get my tomcat and apache web server instances communicating; they are running on two different physical servers. When I attempt a test of the application url, it basically says that a connection cannot be established. I am running the following:
RHEL Release 5.6 (x86_64)
Apache Tomcat 7.0.14
Apache/2.0.64
mod_jk/1.2.32
On the 1st physical server, the apache webserver instance resides:
httpd.conf contains the following:
LoadModule jk_module modules/mod_jk.so
#
JkWorkersFile conf/workers.properties
JkMount /* server2
workers.properties contain the following:
worker.list=server2
worker.server2.port=8009
worker.server2.host=server2.ourlab.com
worker.server2.type=ajp13
worker.server2.lbfactor=1
worker.server2.socket_keepalive=1
On the 2nd physical server, the apache-tomcat instance resides:
server.xml contains the following:
<!-- Define an AJP 1.3 Connector on port 8009 -->
<Connector port="8009" enableLookups="false" protocol="AJP/1.3"
redirectPort="8443" />
<Connector port="8443" maxHttpHeaderSize="8192" protocol="HTTP/1.1" SSLEnabled="true"
[and various other settings]
I am missing something. Can someone please provide help? Thank you...
Hi.
Your configuration looks fine.
The problem then should be with the network.
Try the following :
From the Apache httpd server (command-line),
1) enter :
ping server2.ourlab.com
If you get regular messages showing that the ping packets are being answered, it's fine.
If you get error messages, then you have a basic network problem accessing
server2.ourlab.com from your Apache host.
(faked) example of a "good" answer :
PING server2.ourlab.com (192.168.20.1) 56(84) bytes of data.
64 bytes from server2.ourlab.com (192.168.20.1): icmp_seq=1 ttl=64 time=0.326 ms
64 bytes from server2.ourlab.com (192.168.20.1): icmp_seq=2 ttl=64 time=0.158 ms
64 bytes from server2.ourlab.com (192.168.20.1): icmp_seq=3 ttl=64 time=0.156 ms
Example of a bad answer :
- unknown host
- network is not reachable
etc..
2) If the above is fine, then :
enter :
telnet server2.ourlab.com 8009
It should at least connect (and may drop the connection right away), but the point is : is
it connecting ? If it is, you will get an answer similar to this :
Trying 192.168.20.1...
Connected to colin-int.
Escape character is '^]'.
xxx
Connection closed by foreign host.
