I am running one node application on port 7777 on an ec2 Instance.
I can access that application with ec2 instance's IP address like this -
52.77.122.38:7777 (Not the real IP address)
Now I created one A entry in route53 for abc.mydomain.com and put IP address of my ec2 instance there,
Now loading abc.mydomain.com gives me apache server homepage.
To open this node app on this subdomain,
I removed all the virtualhost entries in apache2.conf file and added this -
<VirtualHost *:80>
ServerName abc.mydomain.com
ServerAlias www.abc.mydomain.com
ProxyRequests on
<Proxy *>
Order deny,allow
Allow from all
</Proxy>
<Location />
ProxyPass http://localhost:7777/
ProxyPassReverse http://localhost:7777/
</Location>
</VirtualHost>
but loading abc.mydomain.com gives me 'this site can't be reached'. While I can still access my app at <ec2's Ip address>:7777
How do I get it running on abc.mydomain.com?

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'm trying to access an internally hosted application on my QNAP at my externally hosted domain, http://mydomiain.com, instead of http://mydomiain.com:12345
I can get the reverse proxy to work when I enter a local IP address of my network, for example the IP address of my QNAP, however, I can't seem to figure out why it wont work from an external domain name. As far as I can tell, the traffic flow is there, I just don't understand why it wont connect.
Is this whole thing even possible or is this not how reverse proxies work?
Current setup:
[External] - Domain DNS:
A Record: Points to home IP address.
[Internal] - Home Router:
Port forwards port 12345 to the IP address of the local server.
[Internal] - Home Server:
Has a revserse proxy setup on the QNAP that is configured as such:
<VirtualHost *:80>
ServerName http://mydomiain.com/
ProxyRequests Off
<Proxy *>
Order deny,allow
Allow from all
</Proxy>
<Location />
Order allow,deny
Allow from all
</Location>
ProxyPreserveHost On
ProxyPass / http://localhost:12345/
ProxyPassReverse / http://localhost:12345/
ProxyStatus On
</VirtualHost>
Ok, so it seems that my issue was on my home router. I was port forwarding the application port, where I needed to port forward port 80 to allow the web traffic.
An Apache web server for the domain “www.abc.lk” is configured and hosted in a hosting server with the IP address 192.168.2.105. Another domain called “www.def.lk” should also be configured with the same content without any duplication. Explain the configuration of the Apache server with name-based virtual hosting for the above requirement?
You have to configure two virtual host with same DocumentRoot but different ServerNames
http://httpd.apache.org/docs/2.2/vhosts/examples.html
# Ensure that Apache listens on port 80
Listen 80
# Listen for virtual host requests on all IP addresses
NameVirtualHost *:80
<VirtualHost *:80>
DocumentRoot /www/example1
ServerName www.abc.com
# Other directives here
</VirtualHost>
<VirtualHost *:80>
DocumentRoot /www/example1
ServerName www.123.com
# Other directives here
</VirtualHost>
Why don't you just use www.abc.lk as ServerName and www.def.lk as ServerAlias in your vhost configuration ?
And of course be sure that both DNS point to the server.
Here is what I use (I think this link lays out all of the solutions or possibilities):
https://realtechtalk.com/Apache_Vhost_HowTo_Serve_Same_Content_using_a_different_domain_and_IP-1730-articles
Here is another way of doing it that is more simple than symlinking or duplicating content between vhosts:
This would be in your vhost.conf
ServerName differentdomain.com
ServerAlias www.differentdomain.com
ProxyPass / http://yourmainsite.com/
ProxyPassReverse / http://yourmainsite.com/
I have a CentOS VPS which is serving HTTP requests via Apache and delivers a HTML site. I am also hosting a Ghost blog on the same VPS, which listens on port 2368. Therefore the main site can be accessed via www.domain.co.uk and the Ghost blog via www.domain.co.uk:2368/blog.
I have configured a Reverse Proxy via Apache so that the port can be hidden from the user, i.e. www.domain.co.uk/blog proxies to www.domain.co.uk:2368/blog.
Is it possible for me to 'hide' the original blog URL so that a user never sees the 2368 port? Therefore, if a user ever accesses www.domain.co.uk:2368/blog this will actually 'redirect' to www.domain.co.uk/blog.
I guess something like a proxy from www.domain.co.uk:2368/blog -> www.domain.co.uk/blog; though this would have to be handled by the node application as it listens on that port?
Virtual Host configuration is as such:
<VirtualHost *:80>
ServerName www.domain.co.uk
ServerAlias domain.co.uk
DocumentRoot /var/www/domain.co.uk/public_html
ErrorLog /var/www/domain.co.uk/error.log
CustomLog /var/www/domain.co.uk/requests.log combined
ProxyRequests Off
ProxyPass /blog http://127.0.0.1:2368/blog
ProxyPassReverse /blog http://127.0.0.1:2368/blog
</VirtualHost>
My question is probably trivial and a duplicate, but either I cannot formulate it or it's not been answered on SO yet.
I have two webservers on a Digital Ocean droplet. One is listening on port 80 and can be accessed via example.com (DNS are on route 53), and the other is on port 8080: how can I make it accessible from example-2.com?
I suppose the software I'm looking for would intercept the HTTP requests, check the referrer, and route those coming from example.com to port 80 and those coming from example-2.com to port 8080. What is it?
This can not be done using only DNS. By default web browsers attempt to connect to port 80 when the url starts with "http" without specifying a port. The user would have to know to connect to port 8080 and explicitly access the URL as
http://example-2.com:8080
I am assuming you are running both web server instances on the same OS environment/IP address, though this would also work for separate hosting environments. What you probably want is a reverse web proxy which can inspect the requested domain name and route to an appropriate server instance. You would run the reverse web proxy on port 80, and probably move the server you are currently running on port 80 to another port (say, 8081).
Apache with mod_proxy and the virtual hosting settings is a possible solution. Assuming example.com and example-2.com point to the Apache instance configure it something like this:
<VirtualHost *:80>
ServerName example.com
ServerAdmin webmaster#example.com
ProxyRequests off
ProxyPreserveHost on
ProxyPass / http://localhost:8081/
ProxyPassReverse / http://localhost:8081/
<Proxy *>
Order allow,deny
Allow from all
</Proxy>
</VirtualHost>
<VirtualHost *:80>
ServerName example-2.com
ServerAdmin webmaster#example-2.com
ProxyRequests off
ProxyPreserveHost on
ProxyPass / http://localhost:8080/
ProxyPassReverse / http://localhost:8080/
<Proxy *>
Order allow,deny
Allow from all
</Proxy>
</VirtualHost>
