Apache Config to send sub dirs to different servers - mod_proxy - reverse-proxy

We use Apache as a reverse proxy server. This has been working well, but I now need to have http://domain.com/sub1 proxy to serverA and http://domain.com/sub2 proxy to serverB. Is this possible? If so, what is the config for it?
Here is my existing config:
...
<VirtualHost 555.55.555.555:80>
ServerName domain.com
DocumentRoot c:/docroot
ProxyPass / http://serverA/
ProxyPassReverse / http://serverA/
</VirtualHost>
...

You've almost got it. You want something like:
ProxyPass /sub1 http://serverA/
ProxyPassReverse /sub1 http://serverA/
ProxyPass /sub2 http://serverB/
ProxyPassReverse /sub2 http://serverB/
Check out the documentation for the ProxyPass directive, there are some neat tricks you can do with it.

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

ProxyPass a URL to different port internally

I've got the following URL.
https://helloworld.com/api/v1/en/user/register
And I'd like to redirect it to different port internally since my api service is running on different port and apache is running on port 80.
I'm doing like this in the apache2 conf but it doesn't work.
ProxyPreserveHost On
ProxyPass ^/(api/v0.9/../.+) http://0.0.0.0:5000/$1
ProxyPassReverse $/(api/v0.9/../.+) http://0.0.0.0:5000/$1
How can I fix it?
Thanks
Have a try with this:
ProxyRequests Off
ProxyPreserveHost On
ProxyPass "/api/v1/" "http://localhost:5000/api/v1/"
ProxyPassReverse "/api/v1/" "http://localhost:5000/api/v1/"

Apache 2.2 and tomcat redirection for subdomains

I have two tomcat servers running in my machine and i want to use apache to redirect the traffic to each server depending on the subdomain.
My httpd.conf is:
<VirtualHost *:80>
ServerName dev.bo.example.com
ProxyPass / ajp://localhost:11009/bo/
ProxyPassReverse / ajp://localhost:11009/bo/
ProxyPassReverseCookiePath /bo/ http://localhost:11001/bo/
</VirtualHost>
<VirtualHost *:80>
ServerName dev.com.example.com
ProxyPass / ajp://localhost:10009/com/
ProxyPassReverse / ajp://localhost:10009/com/
ProxyPassReverseCookiePath /com/ http://localhost:10001/com/
</VirtualHost>
The problem is that the traffic is always direct to the first tomcat server despite the subdomain i use.
It seems that only the first virtual host match despite if i use:
http://dev.com.com.example.com/ or
http://dev.bo.example.com/
Does any know what i am missing here?
Finally, i found that i missed configuration i had to add
NameVirtualHost *:80
to the httpd.conf

When default virtualhost is not available, no virtual hosts are available

I have an apache2 instance proxying requests to several tomcat instances. Sometimes the default virtualhost is unresponsive (tomcat is running but app not responding). When this happens none of the other virtual hosts are reachable through apache but they work going direct to tomcat. Should the default virtualhost be a static page to avoid this issue? Any other settings to tell apache to skip the default if it doesn't respond?
In the httpd.conf there are proxypass/proxypassreverse statements outside of the virutalhost blocks. I don't know if that could be confusing things.
ProxyPass /test/ ajp://localhost:9009/test/
ProxyPassReverse /test/ ajp://localhost:9009/test/
ProxyPass /test2/ ajp:/localhost/9010/test2/
ProxyPassRevers /test2/ ajp://localhost:9010/test2/
NameVirtualHost 192.168.0.1:80
VirtualHost 192.168.0.1:80>
ServerName test.domain.com
ProxyPreserveHost On
ProxyRequests Off
...
ProxyPass / ajp://localhost:9009/test/
ProxyPassReverse / ajp://localhost:9009/test/
...
/VirtualHost>
VirtualHost 192.168.0.1:80>
ServerName test2.domain.com
ServerAlias test2
PorxyPreseveHost On
ProxyRequests Off
...
ProxyPass / ajp://localhost:9010/test2/
ProxyPassReverse / ajp://localhost:9010/test2/
...
/VirtualHost>
Solaris 10
apache 2.2.6
mod_proxy_ajp
It would be suggested to put ProxyPass parameters in VirtualHost section only.

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>
