Apache port forward

Question

I have apache couchDB active on http://localhost:5984/ which i need to access at http://localhost:80/couch/. I need to setup a reverse proxi for this. Need help with the configuration settings.

PS: Whats the best resource to learn about apache?

Solution

Setting up the proxy

To set up a reverse-proxy with Apache2, you first need to enable the Apache proxy module and virtualhosts. To enable the proxy module (mod_proxy), edit the Apache configuration file (Apache/conf/httpd.conf) and uncomment the following lines:

LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_http_module modules/mod_proxy_http.so
LoadModule unique_id_module modules/mod_unique_id.so

You then need to enable VirtualHosts. To do this, just uncomment the following line from the same configuration file:

Include conf/extra/httpd-vhosts.conf

Finally, you need to edit Apache/conf/extra/httpd-vhosts.conf and write in it the proxy directives. From the information you gave, they should look like this:

<VirtualHost *:80>
  ServerAdmin ******
  DocumentRoot "******"
  ServerName *****

  ProxyRequests Off
  ProxyVia Off

  ProxyPass /couch/ http://127.0.0.1:5984/
  ProxyPassReverse /couch/ http://127.0.0.1:5984/
</VirtualHost>

(+ some mLog directives and a few others).

-> Apache restart -> profit.

Learning Apache

You should have a look at the official documentation on the Apache official website or Apachetutor.org, though Google is, and always will be, everyone's friend.

Hi, can you update theanswer according to apache2 ?

[Nicolas BRERO]

Hi, the answer is already intended for Apache2. Anything I can help you with?

[Brian Leishman]

I think he's referring to the fact that there is no "httpd.conf" file in a normal apache2 install on a modern linux install, say, Ubuntu 18.04

whoever ends up here for this awesome answer saving one time and stress energy, might also be interested in how to activate those modules on ubuntu: a2enmod proxy, a2enmod proxy_http, a2enmod unique_id, sudo apachectl -k restart
