mcm modcluster is not working

kittu_lal Sep 9, 2015 1:00 AM

Hi,

Please help anyone, i am unable to configure the mod_cluster with Apache 2.2 with Wildfly.

I am using the modcluster1.2, .

My cluster condifurations are working fine.

I would like to configure the load balance with the Wildfly.

I have gone through with the following code.

Please help me to configure this.

When i.m requesting to http://127.0.0.1/

I'm getting outcome as It Works!

And http://127.0.0.1/mcm/ is giving the following output.

mod_cluster/1.2.6.Final

When i'm requesting to http://127.0.0.1/MiniMVC/index.jsp

I'm getting error in log file as "File does not exist: C:/Apache2/htdocs/MiniMVC"

Here is my configurations.

My httpd.conf file

====================

# This is the main Apache HTTP server configuration file. It contains the

# configuration directives that give the server its instructions.

# See <URL:http://httpd.apache.org/docs/2.2> for detailed information.

# In particular, see

# <URL:http://httpd.apache.org/docs/2.2/mod/directives.html>

# for a discussion of each configuration directive.

# Do NOT simply read the instructions in here without understanding

# what they do. They're here only as hints or reminders. If you are unsure

# consult the online docs. You have been warned.

# Configuration and logfile names: If the filenames you specify for many

# of the server's control files begin with "/" (or "drive:/" for Win32), the

# server will use that explicit path. If the filenames do *not* begin

# with "/", the value of ServerRoot is prepended -- so 'log/access_log'

# with ServerRoot set to '/www' will be interpreted by the

# server as '/www/log/access_log', where as '/log/access_log' will be

# interpreted as '/log/access_log'.

# NOTE: Where filenames are specified, you must use forward slashes

# instead of backslashes (e.g., "c:/apache" instead of "c:\apache").

# If a drive letter is omitted, the drive on which httpd.exe is located

# will be used by default. It is recommended that you always supply

# an explicit drive letter in absolute paths to avoid confusion.

# ServerRoot: The top of the directory tree under which the server's

# configuration, error, and log files are kept.

# Do not add a slash at the end of the directory path. If you point

# ServerRoot at a non-local disk, be sure to point the LockFile directive

# at a local disk. If you wish to share the same ServerRoot for multiple

# httpd daemons, you will need to change at least LockFile and PidFile.

ServerRoot "c:/Apache2"

# Listen: Allows you to bind Apache to specific IP addresses and/or

# ports, instead of the default. See also the <VirtualHost>

# directive.

# Change this to Listen on specific IP addresses as shown below to

# prevent Apache from glomming onto all bound IP addresses.

#Listen 12.34.56.78:80

#Listen 80

#Listen 192.168.1.42:80

# Dynamic Shared Object (DSO) Support

# To be able to use the functionality of a module which was built as a DSO you

# have to place corresponding `LoadModule' lines at this location so the

# directives contained in it are actually available _before_ they are used.

# to be loaded here.

jfclere Sep 16, 2015 3:08 AM (in response to kittu_lal)

Why are you using proxy-list="127.0.0.1:6666" and advertise at the same time?

Check that you can access 127.0.0.1:6666 and if yes check the access_log or add debug in httpd.conf and check the error_log.

mbabacek Sep 16, 2015 5:22 AM (in response to kittu_lal)
Dear Krishna Punna,
do not use 127.0.0.1, your Wildfly instances won't cluster together, use some other boxe's interface, e.g. 192.something
do not use 127.0.0.1 for Apache - Wildfly setup unless all of your instances really reside on a single local box; It is better advised to bind to some other interface anyway
logs would help us to see what's going on
beware of your Windows firewall
Please, do not use mod_cluster 1.2.6. It's obsolete and it contains both severe performance issues and a security CVE.
