sorry, yes of course.
this is a system running Resin and Apache 1.3.2X on windows 2000, identical
servers and a single LVS in front.The setup is using LVS-DR. In order to get
java applets and applications to work thru an LVS without throwing an exception
about permission denied, make sure you have your httpd.conf configured
correctly. In my case I had a problem in the httpd.conf in apache. I didn't
have the mod_caucho directive specified in the Virtual Host directive, only in
the main server config. Once I specified separate mod_caucho directives in the
virtualhost directive it still did not work . Resin needs to be restarted
before these setting take effect for some reason.
Once the resins were restarted, and the caucho directives were put correctly.
the whole thing started to work flawlessly. we now have perfectly balanced java
application servers and the load has dramatically sunk.
here is an example of a mod_caucho directive for apache in a virtual host:
<VirtualHost ip.of.your.LVS:80>
ServerAdmin admin@xxxxxxxxxxxxxxx
DocumentRoot "D:/Resin/default_app"
ServerName appserver.somecompany.com
ErrorLog D:/Logs/Apache/appserver/error.log
CustomLog "|D:/Logs/Apache/rotatelogs.exe
D:/Logs/Apache/appserver/access.log 86400" combined
<IfModule mod_caucho.c>
CauchoConfigFile "D:/Resin/conf/mod_caucho.conf" (<-- this is basically a
shortcut to the main resin.conf file)
</IfModule>
<IfModule mod_rewrite.c>
RewriteEngine off
</IfModule>
</VirtualHost>
hope this helps.
PS: I have just completed a step by step tutorial/document for our internal
purposes on setting up multiple virtually hosted websites all LVSd between 2
servers. Is anyone interested ? I can adjust the document for general purpose
and it is rather detailed, including everything from the Windows 2000 config to
the LVS?
cheers
