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

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 listen and redirect to a different port

I know this has been asked before, I used the highest rated question as a baseline, but I still can't get it to work.
I'm trying to host a website through an iocage jail in FreeBSD.
In my jail I'm hosting a domain called sub.domain.com. I've managed to get Apache to listen to a different port, 10080. So when I go to sub.domain.com:10080 I can access my website.
I would like to be able to go sub.domain.com and also access my website. As far as I understand, I need to redirect using mod_proxy to allow 80 -> 10080.
In httpd.conf I uncommented mod_proxy and added the following
<VirtualHost *:80>
ProxyPreserveHost On
ProxyRequests Off
ServerName www.sub.domain.com
ServerAlias sub.domain.com
ProxyPass / http://localhost:10080
ProxyPassReverse / http://localhost:10080
</VirtualHost>
This doesn't work for me, I still have to go to sub.domain.com:10080 to access my website.
Any tips?
EDIT: current config, also doesn't work
<VirtualHost *:80>
ProxyPreserveHost On
ProxyRequests Off
ServerName <jailip>
ServerAlias <jailip>
ProxyPass / http://<jailip>:10080
ProxyPassReverse / http://<jailip>:10080
</VirtualHost>

Apache Virtual Host - Mod Proxy issues

Not too au fait with Apache, have setup simple virtual hosts before without an issue. Seem to be having a bizarre one, working with 1 IP address and multiple servers.
My second virtual host seems to only look at the first 2 entries and ignores the rest. I have mapped out what I want to happen and how my vhost file looks and the second image is what is happening.
How my virtual hosts are setup and envision the routing to act
How it's currently operating
Now it maybe not right using virtual hosts on both servers?

Avoid giving the same Servername to any two VirtualHost entries. Using x,y,z, etc names is perfectly ok (assumed all resolve to the one IP address from external users).
For simplicity (of maintenance and managing the configuration) also avoid mixing "standard" server configuration (e.g. x on server1) with VirtualHost ones. Any accessible area on your web namespace should be configured via VirtualHost. (The first one in your configuration becomming "default" in that case.)
Using VirtualHosts on both servers is not a problem by itself. You just need to ensure the ServerName from the original HTTP request is correctly being forwarded and arriving at server2. For this you need to add
ProxyPreserveHost On
to your VirtualHost configurations.
It might, however, be easier to give up the name based VirtualHosts usage with server2 and turn to using different ip address or ports for the individual (logical) hosts. Server2 is (at least by concept) an internal setting and not visible to the "external" side. Thus, ease of use is not truly attributable

Reverse Proxy Apache DNS error

Upon setting up my test reverse proxy I have encountered this issue:
http://i.imgur.com/Dk7UiOI.png - Sorry can't post images yet...
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 documentroot other local server

I have a particular subdomain in my apache2 virtualhost 'httpd.conf' file that i would like to redirect to another local apache server. I have a router that redirects all requests on port 80 to the original server.
The second server is NOT on a different global IP address, but on a different local IP address.
Is there any way i can do this,
thanks
You can do this using Apache's proxy functionality. For example:
<VirtualHost *:80>
ServerName myhostname
<Location />
ProxyPass http://address-of-local-server/
ProxyPassReverse http://address-of-local-server/
</Location>
</VirtualHost>
This will cause Apache to proxy requests that match this VirtualHost definition to another server and return the results to the client.
This presumes that you have mod_proxy enabled.
You can mod proxy to any resource identified by it's IP address e.g
<VirtualHost *:80>
ServerName subdomain.domain.com
DocumentRoot /whatever
ProxyRequests Off
<Proxy *>
Order deny,allow
Allow from all
</Proxy>
<Location / >
ProxyPass http://192.168.0.x
ProxyPassReverse http://192.168.0.x
</Location>

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>
