Apache redirect to another port - apache

Question

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>

Answer 1

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

Answer 2

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

Answer 4

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.

Answer 6

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

Answer 7

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>

Answer 8

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

Answer 9

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"

Answer 10

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.

Answer 11

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.

Answer 12

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.

Answer 13

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>

Answer 14

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>

Answer 15

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>
