Tomcat – What configuration changes needed on tcServer to work with Apache Web server

apache-2.2mod-jktomcat

I have Apache Webserver 2.2.17 and tcServer-6.0.20 and I want to dispatch requests from apache to tcserver.

I am using mod_jk.so and I have the following in httpd.conf

LoadModule jk_module modules/mod_jk.so

<IfModule jk_module>
   JkWorkersFile /x/y/apache2/conf/workers.properties
   JkLogFile /x/y/apache2/logs/mod_jk.log
   JkLogLevel info
   JkLogStampFormat "[%a %b %d %H:%M:%S %Y] "
   JkMount /xyz/* ww
</IfModule>

My workers.properties file under /x/y/apache2/conf/workers.properties has

worker.list= ww
worker.ww.type=ajp13
worker.ww.port=12000
worker.ww.host=www.abc.com

I'm new to tcServer (and tomcat) and I don't know what changes I have to make in server.xml on tcServer to get this to work with Apache.

Any help would be appreciated.

You are looking for the AJP connector block in server.xml - by default it's the one listed with port 8009 in it. Basically all you need to do is change that to port 12000 to match your worker.

Here's a complete example of many of things you can set if needed - right now you're running a very bare-bones mod_jk setup, there are Jk* options for Apache you can tune and workers.properties.

<!-- Define an AJP 1.3 Connector on port 8009 -->
<!-- http://tomcat.apache.org/tomcat-6.0-doc/config/ajp.html -->
<Connector port="8009" protocol="AJP/1.3" allowTrace="false"
           emptySessionPath="false" enableLookups="false"
           maxPostSize="2097152" maxSavePostSize="4096" redirectPort="443"
           scheme="http" secure="false" URIEncoding="ISO-8859-1"
           useBodyEncodingForURI="false" xpoweredBy="false"
           useIPVHosts="false" address="127.0.0.1" backlog="10"
           bufferSize="-1" connectionTimeout="60000"
           keepAliveTimeout="60000" maxThreads="200" packetSize="8192"
           request.secret="" request.useSecret="false"
           request.shutdownEnabled="false" tcpNoDelay="true"
           tomcatAuthentication="true" />

How to tell which config file Apache is using

With any *nix application, the easiest method is to query the binary itself. In the case of httpd, I'd imagine the process would be something like this:

$ whereis httpd
/usr/sbin/httpd
$ /usr/sbin/httpd -V
Server version: Apache/2.2.11 (Unix)
Server built:   Jun 17 2009 14:55:13
Server's Module Magic Number: 20051115:21
Server loaded:  APR 1.2.7, APR-Util 1.2.7
Compiled using: APR 1.2.7, APR-Util 1.2.7
Architecture:   64-bit
Server MPM:     Prefork
  threaded:     no
    forked:     yes (variable process count)
Server compiled with....
 -D APACHE_MPM_DIR="server/mpm/prefork"
 -D APR_HAS_SENDFILE
 -D APR_HAS_MMAP
 -D APR_HAVE_IPV6 (IPv4-mapped addresses enabled)
 -D APR_USE_FLOCK_SERIALIZE
 -D APR_USE_PTHREAD_SERIALIZE
 -D SINGLE_LISTEN_UNSERIALIZED_ACCEPT
 -D APR_HAS_OTHER_CHILD
 -D AP_HAVE_RELIABLE_PIPED_LOGS
 -D DYNAMIC_MODULE_LIMIT=128
 -D HTTPD_ROOT="/usr"
 -D SUEXEC_BIN="/usr/bin/suexec"
 -D DEFAULT_PIDLOG="/private/var/run/httpd.pid"
 -D DEFAULT_SCOREBOARD="logs/apache_runtime_status"
 -D DEFAULT_LOCKFILE="/private/var/run/accept.lock"
 -D DEFAULT_ERRORLOG="logs/error_log"
 -D AP_TYPES_CONFIG_FILE="/private/etc/apache2/mime.types"
 -D SERVER_CONFIG_FILE="/private/etc/apache2/httpd.conf"

As you can see - my OS X says the binary, if not directed otherwise, will use the config file: /private/etc/apache2/httpd.conf

If that doesn't help, perhaps Christopher's suggestion of find is the next step.

In your uriworkermap.properties file, it does not appear you have a mapping for /JBossDB
