Good day there.
I'm using mod_proxy to redirect trafic to java applications running on
JBoss instances. I have 3 JBoss instances running seperate apps, the
redirects of 2 of these works fine with mod_proxy configuration but
the third doesn't.
The first 2 instances where set up a long time ago. I've used the one
instance's configuration file for the third one as it was close to
what I required. Here's the 2 configurations.
Working:
<VirtualHost *:80>
ServerAdmin developers@xxxxxxxxxxx
ServerName sub.domain1.com
ProxyRequests Off
ProxyPreserveHost On
ProxyPass / http://sub.domain1.com:18080/
ProxyPass /media !
ProxyPassReverse / http://sub.domain1.com:18080/
ErrorLog /var/log/apache2/domain1-error_log
CustomLog /var/log/apache2/domain1-access_log combined
<Directory "/srv/www/vhosts/domain1">
Options Indexes FollowSymLinks
AllowOverride None
Order allow,deny
Allow from all
</Directory>
</VirtualHost>
The one not working:
<VirtualHost *:80>
ServerAdmin developers@xxxxxxxxxxx
ServerName sub.domain2.com
ProxyRequests Off
ProxyPreserveHost On
ProxyPass / http://sub.domain2.com:28080/
#ProxyPass /media !
ProxyPassReverse / http://sub.domain2.com:28080/
ErrorLog /var/log/apache2/domain2-error_log
CustomLog /var/log/apache2/domain2-access_log combined
<Directory "/srv/www/vhosts/domain2">
Options Indexes FollowSymLinks
AllowOverride None
Order allow,deny
Allow from all
</Directory>
</VirtualHost>
The one that's not working I can browse to
http://sub.domain2.com:28080 without a problem but when I try to
navigate to http://sub.domain2.com I get the following error
irrespective of whether the server it's redirecting to is started or
not.
"
Proxy Error
The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request GET /.
Reason: DNS lookup failure for: sub.domain2.com
Additionally, a 502 Bad Gateway error was encountered while trying to
use an ErrorDocument to handle the request.
"
I'm running on a SuSE and Apache 2.2.4 environment.
Mod_Proxy is loading properly as is evident by the already working
instances. I'm either missing the mistake in the vhost directive or
forgot about a configuration in another file.
