I've configured proxy reverse with apache 2.4 on a server (ip for example 192.168.1.10) as follows:
ProxyRequests Off
ProxyVia Off
ProxyPreserveHost Off
ProxyPass "/foo/" "http://172.20.0.3/"
ProxyPassReverse "/foo/" "http://172.20.0.3/"
mod_proxy_html is loaded.
Where 172.20.0.3 is a docker container, hosted by the server.
When I browse to 192.168.1.10/foo/ I see on the url bar 192.168.1.10/index.php (index.php is the page I actually would like to browse), but the resources required to load index.php are not found. So I get 404 page not found.
Setting / instead of /foo works, but I need to configure other proxy on the same server too.
This Q/A does not provide solution for my case: Apache ProxyPass not loading Resources
What I'm missing? Thank you

I setup a local guacamole server for people in my work to access several VM's that we have running in the server. IN order to access guacamole the have to type http://ip:port/guacamole or after the host override I did in my pfsense DNS resolver http://guac.loc:port/guacamole. The problem is that even that some times is problematic for some of them so I want to do something like http://guac.loc so they can remember it easily. I did it for some with the hosta file but I can't different functionallities for some of them. So can anyone help on how to do that? Can I do it somehow from the web server? Or do I need to setup a DNS Server?
If I understand correctly, you want to have "simpler" URL, without port and "guacamole" path.
Guacamole by default runs under Tomcat on port 8080. However, you can put Apache in front of the Tomcat and proxy request to the guacamole. Apache can proxy and forward all requests to the Guacamole on the given port and path.
Something like the example below should work and also will redirect all http requests to the htpts. It is not mandatory to have SSL enabled, you can proxy http as well.
<VirtualHost *:80>
ServerName guac.loc
Redirect permanent / https://guac.loc/
</VirtualHost>
<VirtualHost *:443>
ServerName guac.loc
SSLEngine on
SSLCertificateFile /etc/ssl/certs/guac-loc.cer
SSLCertificateKeyFile /etc/ssl/private/guac-loc.key
SSLCACertificateFile /etc/ssl/certs/guac-loc-ca.crt
<Location /guacamole/>
ProxyPass http://localhost:8080/guacamole/ flushpackets=on
ProxyPassReverse http://localhost:8080/guacamole/
Order allow,deny
Allow from all
</Location>
</VirtualHost>
I referred the below link and configured the proxy.
https://httpd.apache.org/docs/2.4/howto/reverse_proxy.html
When I configure a proxy for a single application as below in Apache 2.4 in the httpd.conf file, the proxy configuration is working fine. I am able to access my application through the proxy server URL.
ProxyPass / http://host1:8888/
ProxyPassReverse / http://host1:8888/
However If I try configure for two application like below, I am not able to access any of the application.
ProxyPass /nifi http://host1:8888/
ProxyPassReverse /nifi http://host1:8888/
ProxyPass /kibana http://host2:5601/
ProxyPassReverse /kibana http://host2:5601/
Not knowing how you try to reach the application makes it difficult to guess what's might be wrong.
I suggest you to change the proxies config as following:
ProxyPass /nifi/ http://host1:8888/
ProxyPassReverse /nifi/ http://host1:8888/
ProxyPass /kibana/ http://host2:5601/
ProxyPassReverse /kibana/ http://host2:5601/
then try to reach the endpoint pointing your browser to http://youdomain/nifi/ and http://youdomain/kibana/ and check the logs for errors.
I'm very new to setting up apache configs. The docs don't make much sense to me, I have a node app running on a port that functions as a website, but I want to be able to connect to it with my domain. I've been looking around and figured I need to use a ProxyPass to redirect traffic from port 443 (https) to the port the app is running on (I already use apache for other stuff so I didn't want to switch). And it works generally, but is there a way to make only a single ProxyPass rule that will handle all pages (e.g. I go to https://example.com/ it will use https://localhost:4450/ and if I go to https://example.com/example it will use https://localhost:4450/example and for all other pages).
I would think I need a RewriteRule, but I don't really understand how I can get the page (whatever is after the first / or none) using it.
You simply run apache as a reverse proxy here is an example configuration:
<VirtualHost *:443>
SSLEngine On
SSLCertificateFile /etc/apache2/ssl/file.pem
ProxyPreserveHost On
ServerName localhost
ProxyPass / http://0.0.0.0:4450/
ProxyPassReverse / http://0.0.0.0:4450/
</VirtualHost>
and you have to enable the proxy modules like that
a2enmod proxy
a2enmod proxy_http
I am trying to redirect http://eamondev.com:3000 to https://omniatm.eamondev.com with a VirtualHost. I am using node to serve a site to http://eamondev.com:3000. I am using vhost with node like this:
app.use(vhost('omniatm.eamondev.com', express.static('/')));
I have never used vhost and it took me a while to figure this out without having to split up all my code like I was working with more than one site (when I am not), so I'm not sure if it is exactly how it should be for an Apache redirect to work.
In my apache conf file I have:
<VirtualHost *:80>
ServerName omniatm.eamondev.com
ProxyPreserveHost on
ProxyPass / http://localhost:3000/
</VirtualHost>
I am also using WHM on a VPS, I'm not sure if this is relevant or not, but the ServerName (with protocol, what I type into the browser) needs to be https://omniatm.eamondev.com.
I cannot serve node on port 80 of my server (and then redirect to subdomain) because my main site (http://eamondev.com) is running on port 80.
I have referenced most of the stackoverflow questions about this and nothing has worked. I should mention (although I'm not sure exactly how it is relevant, I just saw it in a stackoverflow question I looked at), my hosting support (bluehost) used WHM to set things up with a wildcard ssl certificate to make the omniatm.eamondev.com subdomain https.
How do I redirect http://eamondev.com:3000 to https://omniatm.eamondev.com using apache (or vhost)?
Proxy passing as given in the question will not do any redirects instead it will retain the URL as such and proxy the content from elsewhere. In Apache configuration, we have an option to do redirects, in the bellow sample, we are checking for the host and based on it issuing an redirect to the desired URL
<VirtualHost *:80>
ServerName omniatm.eamondev.com
Redirect / https://omniatm.eamondev.com
<If "%{HTTP_HOST} != 'eamondev.com:3000'">
Redirect "^/?(.*)" "https://omniatm.eamondev.com/$1"
</If>
</VirtualHost>
I have a virtual cloud server on aws where there is tomcat 7 running on port 8080 eg. a.x.y.z:8080 (where a.x.y.z is the public ip). I have an application deployed on the tomcat on context path "hello" so that I can access it like a.x.y.z:8080/hello .
Now I have bought a domain name example.com and have translated it to the public ip a.x.y.z so that now I can access my application via the url example.com:8080/hello but actually what I want is that on hitting example.com I would be able to access my application. How to achieve it ?
You can access your tomcat application with your domain name using mod_proxy modules, please login your server and update your httpd configuration with following code.
ProxyPreserveHost On
ProxyPass / http://0.0.0.0:8080/
ProxyPassReverse / http://0.0.0.0:8080/
NOTE : Update your correct server IP instead of 0.0.0.0 in above code.
Ok, I solved the issue :
After installing apache2, in the /etc/apache2/apache2.conf file
I appended :
<VirtualHost *:80>
ProxyPreserveHost On
ProxyRequests Off
ServerName www.example.com
ServerAlias example.com
ProxyPass / http://localhost:8080/
ProxyPassReverse / http://localhost:8080/
</VirtualHost>
Saved the file and restarted the apache2 server.
With this, whenever I hit example.com, I will get the homepage of tomcat (localhost:8080). then i opened the tomcat manager (example.com/manager/html) and stopped & undeployed the application at root (/) path. (As a result of this, whenever you hit example.com, you will no longer see tomcat homepage, instead a blank page)
Now I deployed my application as root in tomcat. If you are using maven you can do so like here .
As a result of this my application was available in example.com .
(If you don't deploy your application as root, you have to access it using example.com/myapp)
Now, whenever I hit example.com myapp will be accessed.
