I've been trying to find some decent documentation on setting up
Tomcat to communicate with mod_jk2 and Apache over unix sockets. So
far what I've found suggests I only need to alter jk2.properties with
details of the socket, and workers2.properties with the same details.
I've done this and restarted Tomcat and it still appears to be
creating the TCP/IP socket on port 8009, but not creating any unix
socket file.
Has anyone got a working Tomcat 5.5 mod_jk2 configuration using Unix
sockets I'd love to know what you did to set it up.
Hmm, well, there are several things to consider.
First, in order to use UNIX socket, you need to have and link JNI
library specially built for your OS. UNIX sockets are not a part of Java
world and to use them you need JNI library which is a part of mod_jk2
source distribution. You'll also need Apache-Dev RPMs or
libapr+libaprutil, if I recall correctly.
Then you need something like this (this is from my 4.1.24)
jk2.config
----------
apr.NativeSo=/usr/lib/apache2-extramodules/jkjni.so
handler.list=apr,request,channelUnix
channelUnix.file=${jkHome}/work/tomcat.sock
request.tomcatAuthentication=false
workers2.properties

It should be very similar to mod_jk.
Nix.
