Hi,
i get the order to configure a new webhost with apache as the
exclusive connection. Behind the apache should be in furher future a
tomcat farm on serveral servers. Therefor, i install (a) an blank ger-
man linux-distribution (SuSE 8.2) with binaries for Apache 2.0.46 and
Tomcat 4.1.18; read (b) a lot of Documentation and change (c) several
config-files.
The first goal, two running standalone servers with one donain, i
reached very quickly. The second goal, standalone servers with named
virtual hosts(!), are a bit more complex, but reached too.
Now should hide tomcat behind the apache. I create the "workers2.prop-
erties" and the "jk2.properties", set JkUri Statements in apaches vir-
tual host section, change tomcats "server.xml" to use an other
connector and so one. In worst case, it happens nothing. In best case
i get an lot of errors if i ask the apache for an "index.jsp". This
implied for me, that the basic communication are existing, but the
speak "suaheli" and "esperanto" and don't understanding each other. It
was irrelevant what i do, as install the binaries of tomcat 4.1.24, or
tries other possibilities in the config-files, i was not able to
change the situation. In the best case (they talk together, or tries
at least) i get messages like following in apaches error log:
>..[error] msgAjp.receive(): Bad signature 00
>..[notice] BAD MESSAGE: pos=4 len=4 max=8192
>..[notice] 0000 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
>..[error] channelSocket.receive(): Bad header
>..[error] workerEnv.processCallbacks() Error reading reply
>..[error] ajp13.service() ajpGetReply recoverable error 120000
On tomcat side it look like:
.. PM org.apache.tomcat.util.log.CommonLogHandler log
SEVERE: Caught exception executing
[EMAIL PROTECTED], terminating thread
java.lang.NullPointerException
at org.apache.jk.common.ChannelSocket
.processConnection (ChannelSocket.java:597)
at org.apache.jk.common.SocketConnection
.runIt (ChannelSocket.java:707)
at org.apache.tomcat.util.threads
.ThreadPool$ControlRunnable.run (ThreadPool.java:530)
at java.lang.Thread.run (Thread.java:536)
I think i have do all what i can. The next (and last) step are take
the source-code and begin with debugging.
In the appendix i add more or less my config-files. I build an hole
*.tar.bz2 with the complete relevant files (i think), but this is
with 38KB to big for the list. Therfor i add short snipplets from the
right config-files.
Maybe had someone a running minimal configuration, or know where is
one available.
Thanks for help.
Christian.
PS.:
The apache-error.log has for every apache-thread one line like follow:
>..[error] jk2_init() Can't find child 12957 in scoreboard
Over this i readed a little bit in the mailing list, but the change of
the start-sequence don't kill this messages. Had it an effect of the
hole system?
