Subject RE: Load Balance not working for mod_jk???
Date Mon, 24 Jul 2006 16:53:06 GMT
Thanks for the info.

However my Apache log did not log any information listed below.

I checked both error_log and access_log information. There seems that you can
setup the log level for error_log using flags like "info"/"debug".

However there is not such as place for the access_log, can anybody shed some
light on? My Apache version is 2.5.0.24.

Attached my part of the httpd.conf.

====================================================================
ErrorLog logs/error_log

#
# LogLevel: Control the number of messages logged to the error_log.
# Possible values include: debug, info, notice, warn, error, crit,
# alert, emerg.
#
LogLevel debug

#
# The following directives define some format nicknames for use with
# a CustomLog directive (see below).
#
LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\""
combined
LogFormat "%h %l %u %t \"%r\" %>s %b" common
LogFormat "%{Referer}i -> %U" referer
LogFormat "%{User-agent}i" agent

# "combinedio" includes actual counts of actual bytes received (%I) and sent
(%O); this
# requires the mod_logio module to be loaded.
#LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\" %I %O"
combinedio

#
# The location and format of the access logfile (Common Logfile Format).
# If you do not define any access logfiles within a <VirtualHost>
# container, they will be logged here.  Contrariwise, if you *do*
# define per-<VirtualHost> access logfiles, transactions will be

#
#CustomLog logs/access_log common

#
# If you would like to have separate agent and referer logfiles, uncomment
# the following directives.
#
#CustomLog logs/referer_log referer
#CustomLog logs/agent_log agent

#
# For a single logfile with access, agent, and referer information
# (Combined Logfile Format), use the following directive:

CustomLog logs/access_log combined

When you are starting or restarting Apache it should log a line similar 
to the following:

[Sat Jul 22 07:59:41 2006] [notice] Apache/2.0.58 (Unix) DAV/2 
mod_jk/1.2.15 configured -- resuming normal operations

It includes the mod_jk version (mod_jk/1.2.15).

The same should be found via

myserver% strings PATH_TO_MOD_JK/mod_jk.so | grep mod_jk/1.2

 From your log output and a look at the revision history your version is 
most likely 1.2.6. You really should download a new one and build it via 
configure/make.
