Reverse Proxy Apache DNS error - apache

Upon setting up my test reverse proxy I have encountered this issue:

Below is the apache configuartion.
<virtualhost *:80>
ServerAdmin webmaster#localhost
ServerName localhost
ProxyRequests off
<proxy *>
Order deny,allow
Allow from all
</proxy >
ProxyPass / http://192.168.16.103/
ProxyPassReverse / http://192.168.16.103/
</VirtualHost >
Any have any idea's whats causing this, the redirect comes from a web application on an internal IIS server.

Turns out a reboot of the system solved the issue!

Apache as reverse proxy doesn't work

I am trying to publish, behind a proxy, a Spring app (also with Spring Security) which has /x/services as entry point. It is running in Tomcat in 8080 in Google Engine (Debian). I configure Apache 2 as a reverse proxy with next configuration
<VirtualHost *:80>
ServerAdmin webmaster#localhost
ProxyRequests off
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
ProxyPreserveHost On
<Proxy *>
Order allow,deny
Allow from all
</Proxy>
# Servers to proxy the connection, or
# List of application servers Usage
ProxyPass / http://127.0.0.1:8080/x/services/
ProxyPassReverse / http://127.0.0.1:8080/x/services
ServerName localizator.org
ServerAlias *.localizator.org
</VirtualHost>
I checked it against a lot of examples and seems it is OK, but the only response I am getting is the "Index of /" page. And Apache logs are not helping at all.
Any help will be very appreciated.
For those with a similar problem don't forget to do :
sudo a2ensite proxy-host
(lets suppose your .conf file name is proxy-host)

apache2 proxy redirect configuration

This has been asked a bunch of time I realize but I still can't seem to get it working. Here is my situation. I have 2 servers on my network. Server A is public facing which hosts my website. My second server also has apache running with a web application which I would like to access externally. I am not exactly sure how to configure this. My current config looks like this
NameVirtualHost *:2323
<VirtualHost *:2323>
ProxyPass / http://192.168.1.7/ampache
ProxyPassReverse / http://192.168.1.7/ampache
servername slave-1
ProxyPreserveHost On
ProxyRequests Off
</VirtualHost>
So I would like all traffic on https://my_domain.xx:2323 to redirect to 192.168.1.7/ampache
Thank you
I fixed it by doing the following
ProxyRequests Off
ProxyPreserveHost On
<Proxy *>
Order allow,deny
Allow from all
</Proxy>
ProxyPass /airsonic http://192.168.1.7:8088/airsonic
ProxyPassReverse /airsonic http://192.168.1.7:8088/airsonic

Error in Redirect from Apache to Tomcat using mod_proxy

I have apache and Tomcat in my server and im using mod_proxy to redirect from Apache to Tomcat... the apache is running on port 80 and tomcat is running on port 8080
here is my virtual host :
<VirtualHost *:80>
ServerName www.example.ir
ServerAlias example.ir
ProxyRequests Off
ProxyPreserveHost On
<Proxy *>
Order deny,allow
Allow from all
</Proxy>
ProxyPass / http://localhost:8080/example
ProxyPassReverse / http://localhost:8080/example
<Location "/">
Order allow,deny
Allow from all
</Location>
</VirtualHost>
But the problem is when I try www.example.com i get the following error :
HTTP Status 404 - /exampleexample/
so whats wrong with my configuration ?
Thanks and sorry for my poor english
Do you want to execute Tomcat's examples webapp? If this is the case, try following configuration:
ProxyPass / http://localhost:8080/examples/
ProxyPassReverse / http://localhost:8080/examples/
After restarting your Apache, navigate to http://yourhost/.
Hope this helps.

Two servers with mod_proxy, second server host is local ip and shows /proxy/ in url?

I am having some issues in regards to sessions with a second server I am running on my home network. I do this as a hobby and to develop new applications before they officially go live.
I have a domain pointing to my ip and resolves successfully to server 1, but after configuring mod_proxy to send specific domains to server 2 I am getting some unwanted errors and results. I want the second server to act as a normal server and just go through the first server since my current router can only send port 80 to one local ip and not filter it.
I have a.mydomain.com for my second server and it resolves fine but When I try to use a web application on this second server I get the following error
Warning: You are now accessing Mydomain from http://10.0.1.38/, but Mydomain has been configured to run at this address: http://a.mydomain.com/
Can i fix this?
Also when trying to access phpmyadmin via the a.mydomain.com/phpmyadmin it will change to a.mydomain.com/proxy/phpmyadmin after logging in, can i change this so that it's basically seamless and does not add /proxy.
Here is my vhost config for server 1
<VirtualHost *:80>
DocumentRoot /var/www/html
ServerName www.server1domain.net
</VirtualHost>
<VirtualHost *:80>
ProxyPreserveHost On
ServerName a.mydomain.com
<Proxy *>
Order deny,allow
Allow from all
</Proxy>
ProxyPass / http://10.0.1.38/
ProxyPassReverse / http://10.0.1.38/
</VirtualHost>
Here is the vhost config for server 2
<VirtualHost *:80>
ServerAdmin admin#mydomain.com
DocumentRoot /var/www/mydomaincom
ServerName a.mydomain.com
</VirtualHost>
I am running Centos 6.4
Alright I finally figured this out, some of the stuff is a little obvious now but this works for anyone else in a similar situation.
So earlier in my http.conf I had this
<IfModule mod_proxy.c>
ProxyRequests Off
<Proxy *>
Order deny,allow
Allow from all
</Proxy>
# destination directory
ProxyPass /proxy http://10.0.1.38
ProxyPassReverse /proxy http://10.0.1.38
</IfModule>
There seems to be two problems with this, it seems to add the /proxy/ directory and also is wrong since the ip does not have a trailing slash, thus I changed it to this
<IfModule mod_proxy.c>
ProxyRequests Off
<Proxy *>
Order deny,allow
Allow from all
</Proxy>
</IfModule>
And my http.conf vhost config for the first server looks like this now
<VirtualHost *:80>
ProxyPreserveHost On
ProxyPass / http://10.0.1.38/
ServerName a.mydomain.com
</VirtualHost>
If you forget the trailing slash after the ip you will most likely end up with 502 errors: Could not resolve dns
The second servers vhost config looks like this
<VirtualHost *:80>
ServerAdmin admin#mydomain.com
DocumentRoot /var/www/mydomain
ServerName a.mydomain.com
</VirtualHost>
Hope that helps anyone else with similar issues.

Apache redirect to another port

I've struggled with this for some time and am definitely doing something wrong.
I have Apache server and a JBoss server on the same machine. I'd like to redirect traffic for mydomain.example to JBoss localhost:8080/example. The DNS is currently setup for mydomain.example and it will go straight to port 80 when entered into the browser.
My question is how do I redirect to a different port when a certain domain name comes to Apache (in this case, mydomain.example)?
<VirtualHost ip.addr.is.here>
ProxyPreserveHost On
ProxyRequests Off
ServerName mydomain.example
ProxyPass http://mydomain.example http://localhost:8080/example
ProxyPassReverse http://mydomain.example http://localhost:8080/example
</VirtualHost>
After implementing some suggestions:
Still not forwarding to port 8080
<VirtualHost *:80>
ProxyPreserveHost On
ProxyRequests Off
ServerName mydomain.example
ServerAlias www.mydomain.example
ProxyPass http://mydomain.example http://localhost:8080/example
ProxyPassReverse http://mydomain.example http://localhost:8080/example
</VirtualHost>
You should leave out the domain http://example.com in ProxyPass and ProxyPassReverse and leave it as /. Additionally, you need to leave the / at the end of example/ to where it is redirecting. Also, I had some trouble with http://example.com vs. http://www.example.com - only the www worked until I made the ServerName www.example.com, and the ServerAlias example.com. Give the following a go.
<VirtualHost *:80>
ProxyPreserveHost On
ProxyRequests Off
ServerName www.example.com
ServerAlias example.com
ProxyPass / http://localhost:8080/example/
ProxyPassReverse / http://localhost:8080/example/
</VirtualHost>
After you make these changes, add the needed modules and restart apache
sudo a2enmod proxy && sudo a2enmod proxy_http && sudo service apache2 restart
I solved this issue with the following code:
LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_http_module modules/mod_proxy_http.so
<VirtualHost *:80>
ProxyPreserveHost On
ProxyRequests Off
ServerName myhost.example
ServerAlias www.myhost.example
ProxyPass / http://localhost:8080/
ProxyPassReverse / http://localhost:8080/
</VirtualHost>
I also used:
a2enmod proxy_http
I wanted to do exactly this so I could access Jenkins from the root domain.
I found I had to disable the default site to get this to work. Here's exactly what I did.
$ sudo vi /etc/apache2/sites-available/jenkins
And insert this into file:
<VirtualHost *:80>
ProxyPreserveHost On
ProxyRequests Off
ServerName mydomain.example
ServerAlias mydomain
ProxyPass / http://localhost:8080/
ProxyPassReverse / http://localhost:8080/
<Proxy *>
Order deny,allow
Allow from all
</Proxy>
</VirtualHost>
Next you need to enable/disable the appropriate sites:
$ sudo a2ensite jenkins
$ sudo a2dissite default
$ sudo service apache2 reload
Found this out by trial and error. If your configuration specifies a ServerName, then your VirtualHost directive will need to do the same. In the following example, awesome.example.com and amazing.example.com would both be forwarded to some local service running on port 4567.
ServerName example.com:80
<VirtualHost example.com:80>
ProxyPreserveHost On
ProxyRequests Off
ServerName awesome.example.com
ServerAlias amazing.example.com
ProxyPass / http://localhost:4567/
ProxyPassReverse / http://localhost:4567/
</VirtualHost>
I know this doesn't exactly answer the question, but I'm putting it here because this is the top search result for Apache port forwarding. So I figure it'll help somebody someday.
This might be an old question, but here's what I did:
In a .conf file loaded by Apache:
<VirtualHost *:80>
ServerName something.com
ProxyPass / http://localhost:8080/
</VirtualHost>
Explanation: Listen on all requests to the local machine's port 80. If I requested "http://something.com/somethingorother", forward that request to "http://localhost:8080/somethingorother". This should work for an external visitor because, according to the docs, it maps the remote request to the local server's space.
I'm running Apache 2.4.6-2ubuntu2.2, so I'm not sure how the "-2ubuntu2.2" affects the wider applicability of this answer.
You have to make sure that the proxy is enabled on the server. You can do so by using the following commands:
a2enmod proxy
a2enmod proxy_http
service apache2 restart
If you don't have to use a proxy to JBoss and mydomain.example:8080 can be "exposed" to the world, then I would do this.
<VirtualHost *:80>
ServerName mydomain.example
Redirect 301 / http://mydomain.example:8080/
</VirtualHost>
Just use a Reverse Proxy in your apache configuration (directly):
ProxyPass /foo http://foo.example.com/bar
ProxyPassReverse /foo http://foo.example.com/bar
Look here for apache documentation of how to use the mod
My apache listens to 2 different ports,
Listen 8080
Listen 80
I use the 80 when i want a transparent URL and do not put the port after the URL
useful for google services that wont allow local url?
But i use the 8080 for internal developing where i use the port as a reference for a "dev environment"
You need 2 things:
Add a ServerAlias www.mydomain.example to your config
change your proxypass to ProxyPassMatch ^(.*)$ http://localhost:8080/example$1, to possibly keep mod_dir and trailing slashes from interfering.
Apache supports name based and IP based virtual hosts. It looks like you are using both, which is probably not what you need.
I think you're actually trying to set up name-based virtual hosting, and for that you don't need to specify the IP address.
Try < VirtualHost *:80> to bind to all IP addresses, unless you really want ip based virtual hosting. This may be the case if the server has several IP addresses, and you want to serve different sites on different addresses. The most common setup is (I would guess) name based virtual hosts.
This is working in ISPConfig too. In website list get inside a domain, click to Options tab, add these lines: ;
ProxyPass / http://localhost:8181/
ProxyPassReverse / http://localhost:8181/
Then go to website and wolaa :) This is working HTTPS protocol too.
Try this one-
<VirtualHost *:80>
ProxyPreserveHost On
ProxyRequests Off
ServerName www.adminbackend.example.com
ServerAlias adminbackend.example.com
ProxyPass / http://localhost:6000/
ProxyPassReverse / http://localhost:6000/
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>
This is how I redirected part of the requests to one url and rest to another url:
<VirtualHost *:80>
ProxyPreserveHost On
ProxyRequests Off
ServerName localhost
ProxyPass /context/static/content http://localhost:80/web/
ProxyPassReverse /context/static/content http://localhost:80/web/
ProxyPass / http://localhost:8080/
ProxyPassReverse / http://localhost:8080/
</VirtualHost>
All are excellent insights to accessing ports via domain names on virtual servers. Do not forget, however, to enable virtual servers; this may be commented out:
NameVirtualHost *:80
<Directory "/home/dawba/www/">
allow from all
</Directory>
We run WSGI with an Apache server at the domain sxxxx.com and a golang server running on port 6800. Some firewalls seem to block domain names with ports. This was our solution:
<VirtualHost *:80>
ProxyPreserveHost On
ProxyRequests Off
ServerName wsgi.sxxxx.example
DocumentRoot "/home/dxxxx/www"
<Directory "/home/dxxx/www">
Options Indexes FollowSymLinks
AllowOverride None
Order allow,deny
Allow from all
</Directory>
ScriptAlias /py/ "/home/dxxxx/www/py/"
WSGIScriptAlias /wsgiprog /home/dxxxx/www/wsgiprog/Form/Start.wsgi
</VirtualHost>
<VirtualHost *:80>
ProxyPreserveHost On
ProxyRequests Off
ServerName sxxxx.com
ServerAlias www.sxxxx.com
ProxyPass / http://localhost:6800/
ProxyPassReverse / http://localhost:6800/
</VirtualHost>
