Apache http proxy and reverse proxy - apache

I need to define two virtual host that should forward my requests to different web applications.
IP of PC where appache is installed is: 192.168.100.208.
IP of application server where application are installed is: 192.168.100.50
<VirtualHost *:7778>
ServerName 192.168.100.208
ProxyRequests On
ProxyPreserveHost Off
<Proxy *>
Order allow,deny
Allow from all
</Proxy>
ProxyErrorOverride On
ProxyPass / http://192.168.100.50:9081/app1/
ProxyPassReverse / http://192.168.100.50:9081/app1/
<Location>
Order allow,deny
Allow from all
</Location>
and I need to have:
<VirtualHost *:7777>
ServerName 192.168.100.208
ProxyRequests On
ProxyPreserveHost Off
<Proxy *>
Order allow,deny
Allow from all
</Proxy>
ProxyErrorOverride On
ProxyPass / http://192.168.100.50:9081/app2/
ProxyPassReverse / http://192.168.100.50:9081/app2/
<Location>
Order allow,deny
Allow from all
</Location>
So when I type in browser:
192.168.100.208:7778 i should get page from 192.168.100.50:9081/app1
and
192.168.100.208:7777 i should get page from 192.168.100.50:9081/app2
But above is not working. Where is mistake?

Make sure to have the following configured also:
#
# Use name-based virtual hosting.
#
NameVirtualHost *:7778
NameVirtualHost *:7777

Setting up reverse proxy using Apache on Windows Server 2008 R2

I am trying to setup Reverse Proxy using Apache Server 2.4.23 for two different domain. One domain is pointing to localhost site and other is pointing to other server web site. Here are my configuration
Listen 111.111.11.222:80
Listen 111.111.11.333:80
<VirtualHost 111.111.11.222:80>
ServerName myapp.com
ErrorLog "logs/app_error_log"
CustomLog "logs/app_access_log" common
ProxyRequests Off
ProxyPreserveHost On
<Proxy *>
Order deny,allow
Allow from all
</Proxy>
ProxyPass / http://111.111.11.222:8090/
ProxyPassReverse / http://111.111.11.222:8090/
<Location />
Order allow,deny
Allow from all
</Location>
</VirtualHost>
<VirtualHost 111.111.11.333:80>
ServerName myauditor.com
ProxyRequests Off
# ProxyPreserveHost On
ErrorLog "logs/auditor_error_log"
CustomLog "logs/auditor_access_log" common
<Proxy *>
Order deny,allow
Allow from all
</Proxy>
ProxyPass / http://www.mycompamy.com/
ProxyPassReverse / http://www.mycompany.com/
</VirtualHost>
In these settings, first "myapp.com" is working fine as needed. However when I try myauditor.com then instead of acting it as reverse proxy, it is redirecting to www.mycompany.com.
In myauditor.com setting, if I un-comment and use ProxyPreserveHost On then myauditor.com start giving me error
Invalid URL
The requested URL "http://%5bNo%20Host%5d/", is invalid.
Reference #9.2d3d6b68.1485193636.126886bd
I am new to Apache so I am not sure, when ProxyPreserveHost is working fine in first VirtualHost then why it causing issue in second VirtualHost.

502 Proxy Error - MeteorJS on Apache

I am new to Meteor, and I have an existing server that is hosting a few websites (CentOS). I use Apache to serve the sites and wanted to have a Meteor app running on a subdomain.
Here is what I have for the Meteor site in httpd.conf:
<VirtualHost *:80>
ServerName www.subdomain.domain.net
ServerAlias subdomain.domain.net
DocumentRoot /var/www/my_meteor_directory/testapp
ProxyRequests Off
<Proxy *>
Order allow,deny
Allow from all
</Proxy>
ProxyPass / http://127.0.0.1:3000
ProxyPassReverse / http://127.0.0.1:3000
</VirtualHost>
I also have this at the bottom of my httpd.conf file:
<Proxy *>
Allow from 127.0.0.1
</Proxy>
ProxyPreserveHost On
ProxyPassMatch ^/(.+\.cf[cm])(/.*)?$ ajp://localhost:3000/$1$2
I set the app to run on port 3000 and when I try to hit it in the browser (subdomain.domain.net) I get these 502 errors:
Any suggestions?
Try this...
<VirtualHost *:80>
ServerName meteorapp.example.com
ProxyRequests off
<Proxy *>
Order deny,allow
Allow from all
</Proxy>
<Location />
ProxyPass http://localhost:8080/
ProxyPassReverse http://localhost:8080/
</Location>
</VirtualHost>
then reload the server

Can we allow unsecure websocket(ws://) over https protocol?

I have already tried using ws:// over https in firefox using some flag configuration. Is there any way to enable this configuration in IE 10 . May be by adding some reg entry it can be done but i don't know exactly which key vale to edit?
I have configured my https using apache httpd service. Which routes to my play portal URL. Is there any setting/config extra i am missing. Here is my httpd configuration:
<VirtualHost *:80>
ServerName myhost
<Proxy *>
Order deny,allow
Allow from all
</Proxy>
SSLEngine on
SSLProxyEngine On
SSLCertificateFile /etc/ssl/certs/my.crt
SSLCertificateKeyFile /etc/ssl/private/my.key
ProxyRequests on
ProxyPreserveHost off
<Location />
SetHandler balancer-manager
Order allow,deny
Allow from all
</Location>
#ProxyPass /excluded !
ProxyPass / http://host-to-route:9701/
ProxyPassReverse / http://host-to-route:9701/
</VirtualHost>
Please suggest.
Thanks,

How can I setup apache to proxy for two different tomcats on the same server?

I have to have two different tomcats on the same server both to be targeted by different domain names. I was wondering if it is possible for apache to proxy to both. I haven't found any documentation that with explanation to this solution yet.
I have below an example virtual host of the two I have on the server which proxies for the single tomcat instance so far:
<VirtualHost *:80>
ServerName tinderbox.mycompany.com
ProxyRequests Off
ProxyPreserveHost On
<Proxy *>
Order deny,allow
Allow from all
</Proxy>
ProxyPass / http://localhost:8080/
ProxyPassReverse / http://localhost:8080/
</VirtualHost>
Something like
<VirtualHost *:80>
ServerName tinderbox.mycompany.com
ProxyRequests Off
ProxyPreserveHost On
<Proxy *>
Order deny,allow
Allow from all
</Proxy>
ProxyPass / http://localhost:8080/
ProxyPassReverse / http://localhost:8080/
</VirtualHost>
<VirtualHost *:80>
ServerName othername.mycompany.com
ProxyRequests Off
ProxyPreserveHost On
<Proxy *>
Order deny,allow
Allow from all
</Proxy>
ProxyPass / http://localhost:9090/
ProxyPassReverse / http://localhost:9090/
</VirtualHost>
Essentially, repeat the VirtualHost block, change the server name so the block applies to your second domain name and change the target of the ProxyPass to whatever ports the second Tomcat instance is using.

Avoid the conflict on port 80 between nodejs and apache

The goal is to listen on port 80 with nodejs without killing apache.
I have to say my knowledges in network are very basic.
UPDATE
I am trying to use ProxyPass ProxyPassReverse on my local machine but there is something wrong.
Alias /test /media/www-dev/public/test
<Directory /media/www-dev/public/test>
Options Indexes FollowSymLinks MultiViews
AllowOverride All
Order allow,deny
Allow from all
</Directory>
ProxyRequests off
<Proxy *>
Order deny,allow
Allow from all
</Proxy>
<Location />
ProxyPass /test http://localhost:3000/
ProxyPassReverse /test http://localhost:3000/
</Location>
When i launch http://localhost/test on my browser i get a message Cannot GET /test/, if i stop to listen on the port 3000, then i get 503 Service Temporarily Unavailable my node app is listening on the port 3000.
If if commente the "Proxy" lines, i can reach the URL http://localhost/test again.
Why can i not access the URL http://localhost/test ? Is it because the proxy try to reach http://localhost:3000/ instead following the path of the alias /test ?
Thanks !
you need to create a virtual host in apache for your node app and proxy over the requests.
here is what mine looks like in /etc/apache/sites-available/dogself.com
<VirtualHost 69.164.218.75:80>
ServerName dogself.com
ServerAlias www.dogself.com
DocumentRoot /srv/www/dogself.com/public_html/
ErrorLog /srv/www/dogself.com/logs/error.log
CustomLog /srv/www/dogself.com/logs/access.log combined
ProxyRequests off
<Proxy *>
Order deny,allow
Allow from all
</Proxy>
<Location />
ProxyPass http://localhost:3000/
ProxyPassReverse http://localhost:3000/
</Location>
</VirtualHost>
It sounds like you have a lot to research before you can get this working though. start reading docs
Alternative approach for a virtual host would be the following
<VirtualHost *:80>
ServerAdmin info#DOMAIN.com
ServerName DOMAIN.com
ServerAlias www.DOMAIN.com
ProxyRequests off
<Proxy *>
Order deny,allow
Allow from all
</Proxy>
<Location />
ProxyPass http://localhost:3000/
ProxyPassReverse http://localhost:3000/
</Location>
</VirtualHost>
To fix the Internal Server ERROR just enable the right apache extension.
sudo a2enmod proxy_http
sudo service apache2 restart
