Apache Web Server Aws
- If you using Amazon Linux 2 AMI you need to follow these steps. In AMI2 they are using systemctl for managing services check if it is installed on your machine 2.systemctl list-units -type=service by this command check if tomcat.service is listed.
- Apache http Server. Apache is a very well known open-source Web Server. It is not only popular but also very old Web Server. Like any other Web Servers, Apache also accepts requests from the clients, search for the requested queries and then send the response back to them.

- The Apache HTTP Server, colloquially called Apache, is a free and open-source cross-platform web server over 60% of companies are using Apache web server for website hosting and maintaining. Step 1: After created account on AWS then we have to go for services that are present at the top left corner, it display all the services on the amazon.
The web server runs on an Amazon EC2 instance using Amazon Linux, and the MySQL database is an MySQL DB instance. Both the Amazon EC2 instance and the DB instance run in a virtual private cloud (VPC) based on the Amazon VPC service.

In this article I cover how to install Apache HTTP Server into Ubuntu 18.04 LTS.
This article is part 2 of a series on how to create a Tomcat server in AWS. In part 1 we created an Ubuntu 18.04 LTS server in AWS EC2. We now add Apache HTTP Server as a front-end for Tomcat.
Motivations
When discussing reasons why you should have an Apache Web Server as a front-end to Tomcat, people usually talk about load balancing, fast serving of static content, enhanced security and so forth. These are all good reasons. Epson scan software mac download. My main reason though is that I want to serve custom-branded pages even when Tomcat is down.
Installation
Apache is a very mature software. You can make life marginally more difficult for yourself by trying to install a specific version. Or you can just take the easy option and install the version packaged with the Ubuntu. I choose to embrace the lazy pragmatist within, so I’ve gone for the latter.
This installs Apache to the /etc/apache2 directory. You can check what version is installed using:
With Apache installed, you can immediately test it by confirming that its default page is accessible at the Public IP or domain name of your server.
Configuration
Remove Default Virtual Host
OK, we’ve seen the default Apache web page for long enough. Time to get rid of it. If you actually took the time to read the default page, the following command will make sense.
Static Content
We need to create a directory to hold the static content for our site. It seems the Apache convention is to make a sub-directory in /var/www
What you will want to put in here is entirely up to you. For the purposes of my example, I’m going to put just one HTML file.
With trivial contents.
For a real site, you would build a rather more impressive page.
Proxy AJP
Although Tomcat isn’t installed yet, let’s jump right in and enable Apache’s Proxy AJP module. We will use it to forward requests to Tomcat in the next article.
Virtual Host
Now we need to create a so-called virtual host for our website. For the purposes of this post, we’ll cover just a HTTP (port 80) virtual host file. HTTPS (port 443) is covered later in the series.
I elect to create a common file that can be shared, eventually, by both the HTTP and HTTPS virtual host configurations.
With contents:
The DocumentRoot element sets the root to the static content directory we created earlier.
The ErrorLog and CustomLog elements can be almost anything you want. What I have done is quite conventional.
I have told Apache to pass all requests through to Tomcat, except for requests to /error.html. All requests to Tomcat, and responses from it, are handled by the Proxy AJP module we enabled earlier.
If Tomcat is down (or not installed), we expect the AJP request to return a 503 (Service Unavailable). In that case, Apache will serve /error.html.
With the common file in place, we can now create the HTTP (port 80) virtual host file.
With contents:
The virtual host can then be enabled.

Instruct Apache to reload its settings.
And if we surf now to the Public IP or domain name, voila, we see the error page. This is because Tomcat is not yet installed, so all the Proxy AJP forwards fail. Therefore we will get this error page served for any URI.
Please remember, you can make your custom error document look a lot better than my trivial example.
Hardening
In the references, I include links to guides on how to harden an Apache installation. Most of the advice is already incorporated in a default installation of Apache Web Server in Ubuntu. Gimp macbook pro. What follows is a couple of steps I recommend.
Server Signature
If we didn’t have a custom error document, Apache would serve the following page when Tomcat was down (or not installed). This would reveal details, such as server version, that can give an attacker a head start.
To get rid of this signature from default pages, we need to edit the security configuration.
And disable the the ServerSignature.
Server Tokens

Even with the ServerSignature off, responses from Apache still report the server version in the HTTP response header. This can be viewed using Firefox or Chrome web development tools.
To remove this, again edit the security configuration.
And set ServerTokens to the least revealing setting.
