Apache2 Https Proxy

Apache is the most popular web server. You can also use Apache as a frontend proxy server for backend running applications like Node.js. This tutorial will help you to set up your Apache server as a frontend proxy server for your Node.js application with easy steps.

Apache HttpClient - Proxy Authentication - In this chapter, we will learn how to create a HttpRequest authenticated using username and password and tunnel it through a proxy to a target host, using an ex. Here is what I have used to access proxy autocomplete google places requests through local host on an installation of Apache including ssl support (version 2.2 for windows). Edit the apache file httpd.conf. Under Apache 1.x, modproxy only supported HTTP/1.0, but from Apache 2.0, it supports HTTP/1.1. This distinction is particularly important in a proxy, because one of the most significant changes between the two protocol versions is that HTTP/1.1 introduces rich new cache control mechanisms.

Before Start

I am using Ubuntu 18.04 instance hosted on DigitalOcean.
Installed latest Node.js version using this tutorial on this Linux machine.

Step 1 – Create Sample Node Application

As you are here 🙂 You must have a running Node.js application on some port. We assume you are running your application on port 3000. For the demonstration purpose, I am creating a sample web application on Node.js and run on port 3000. So it will be easier to understand for you.

Then, add the following content in the JavaScript file.

Your Node application is ready to serve on port 3000. Let’s start the Node.js application in the background.

And access this in the browser. You will see the result like below:

Step 2 – Install Apache Server

Now install the Apache web server using the default Package manager. The Ubuntu and Debian based systems use apt, Fedora and CentOS/RHEL 8 use DNF and CentOS/RHEL 7/6 uses yum. Apache packages is available under default repositories on almost operating systems.

After installation of Apache web server, you must have enabled the Proxy module. This module is enabled in Apache for users who installed using rpm packages. If you don’t have enabled edit your Apache configuration /etc/httpd/conf/httpd.conf or for Apache 2.4 /etc/httpd/conf.modules.d/00-proxy.conf file and uncomment the following lines or put them in the file.

For the Debian based systems use the following command to enable the Proxy module with Apache.

Step 3 – Configure Apache VirtualHost

As you have configured and running a Node.js demo server. Now, start configuration with Apache web server. Create a virtual host configuration file for your domain under /etc/apache2/sites-available/ directory.

and add the following content.

it's recommended you use the mod_proxy configuration below.<p><h3><span>Enabling AJP in OpenNMS Jetty</span></h3><p>As of OpenNMS 1.3.10, the Jetty included in OpenNMS has AJP support.

Checkthat the main page works. Go to a page in a subdirectory (e.g. Adminor /rtc/) and make sure that works, too.You may find clearing your browser cache useful if you have been using a different method previously. I'm not 100% sure this cured my problem whereby many of the initial links at login would keep on using http instead of https. Once logged in it was fine. Clearing the browser cache sorted this out.</p><h2 id='enable-https-apache2'>Enable Https Apache2</h2><h3><span>Notes</span></h3><p>When putting OpenNMS behind a proxy, there are two places where it needs toknow what its real URL is.</p><p>First, OpenNMS puts an HTML <code><base></code> tag on each page. TheURL in this tag needs to be correct: the scheme needs to be https, not http,even though Jetty sees all its requests come in over http. That's whatthe <code>opennms.web.base-url</code> property is for.</p><p>Second, Jetty needs to know what URL to redirect to when it generatesredirections for authentication and logout. The way to handle thisis to let Jetty put its internal HTTP URL in the redirect, and have Apacherewrite it to be HTTPS. That's what the ProxyPassReverse directive is for.</p><h2 id='apache2-reverse-proxy-ssl'>Apache2 Reverse Proxy Ssl</h2><h2><span>Using mod_proxy_ajp</span></h2><h2 id='apache-proxy-server'>Apache Proxy Server</h2><p>The following configuration helps you to configure OpenNMS in a hot standby (failover) configuration. This enables failover of the web application for users in that they will no be required to know 2 different URLs to browse to for the OpenNMS UI and they will automatically be directed to the Primary when it is available. You will need mod_proxy_ajp installed.</p><p>In this configuration, when the OpenNMS web application is available on server1, all proxy traffic will be directed to server1. When the OpenNMS web application is not available on server1, all traffic will be directed to server2. The status attribute on the server2 ajp connection definition initializes the connection to a 'Hot stand-by' mode.</p><h2 id='apache-proxy-https-without-certificate'>Apache Proxy Https Without Certificate</h2><div> Retrieved from 'https://wiki.opennms.org/wiki/index.php?title=Apache2_configuration&oldid=19955' </div>
