In 2002, Igor Sysoev began work on Nginx as an answer to the C10K problem, which was a challenge for web servers to begin handling ten thousand concurrent connections as a requirement for the modern web. The initial public release was made in 2004, meeting this goal by relying on an asynchronous, event-driven architecture.

Nginx has grown in popularity since its release due to its lightweight resource utilization and its ability to scale easily on minimal hardware. Nginx excels at serving static content quickly and is designed to pass dynamic requests off to other software that is better suited for those purposes.

Nginx is often selected by administrators for its resource efficiency and responsiveness under load. Advocates welcome Nginx’s focus on the core web server and proxy features.

The Apache HTTP Server was created by Robert McCool in 1995 and has been developed under the direction of the Apache Software Foundation since 1999. Since the HTTP web server is the foundation’s original project and is by far their most popular piece of software, it is often referred to simply as “Apache”.

The Apache web server has been the most popular server on the internet since 1996. Because of this popularity, Apache benefits from great documentation and integrated support from other software projects.

Apache is often chosen by administrators for its flexibility, power, and widespread support. It is extensible through a dynamically loadable module system and can process a large number of interpreted languages without connecting out to separate software.

Nginx runs on modern Unix-like systems; however, it has limited support for Windows.

Nginx follows an event-driven approach to serving client requests.

Nginx can handle multiple client requests concurrently and efficiently with limited hardware resources.

Nginx can't process dynamic content natively.

Nginx is both a web server and a proxy server.

Since modules cannot be loaded dynamically, they must be compiled within the core software itself.

A single thread can handle multiple connections.

Nginx can simultaneously run thousands of connections of static content two times faster than Apache and uses little less memory.

Apache runs on all Unix-like systems such as Linux, BSD, etc. as well as completely supports Windows.

Apache uses a multi-threaded approach to process client requests.

Apache cannot handle multiple requests concurrently with heavy web traffic.

Apache processes dynamic content within the web server itself.

Modules are dynamically loaded or unloaded, making them more flexible.

A single thread can only process one connection.

The performance of Apache for static content is lower than Nginx.

For many applications, NGINX and Apache complement each other well. A very common starting pattern is to deploy the open-source NGINX software as a proxy (or NGINX Plus as the application delivery platform) in front of an Apache-based web application. NGINX performs the HTTP-related heavy lifting – serving static files, caching content, and offloading slow HTTP connections – so that the Apache server can run the application code in a safe and secure environment.

As you can see, both Apache and Nginx are powerful, flexible, and capable. Deciding which server is best for you is largely a function of evaluating your specific requirements and testing with the patterns that you expect to see.

There are differences between these projects that have a very real impact on the raw performance, capabilities, and implementation time necessary to get each solution up and running. However, these usually are the result of a series of trade-offs that should not be casually dismissed. In the end, there is no one-size-fits-all web server, so use the solution that best aligns with your objectives.

In this blog, we will discuss about NGINX and Apache and their differences .Additionally, we understand how to cooperate with them.

 Overview of the differences between Apache and NGINX

There is one server where Apache HTTPD was installed by source, so, there is no Yum/RPM register of installed Apache HTTPD.

When trying to install PHP 5.x packages using yum, it gives errors saying the dependent package "httpd" was not found.

What's the correct approach to install PHP and the remaining PHP RPM children packages (as example php-pecl-jsonc RPM), since yum is not allowing it to be installed?

Installing PHP on a server where HTTPD was installed by source

I would like with the intention to glance through my proxy logs and spot if I will perceive viable abuse to my websites. I'm extra of a developer than a sysop so could recognize some basic statistics on how to filter out my logs finding some occurrences for requests from the same IP addresses, i.e.

How to filter http logs to identify DDOS

I've been given a purchaser seeking to get the right of entry to consider one of my websites, and they preserve getting this error > ssl_error_rx_record_too_long

They are getting this mistake on all browsers, all structures. I cannot reproduce the hassle in any respect.

My server and myself are placed within the u.S.A., the customer is positioned in India.

I googled the problem, and the principle supply seems to be that the SSL port is speaking in HTTP. I checked my server, and this isn't taking place. I tried the answer mentioned right here, however, the consumer has said it did not restore the problem.

ssl_error_rx_record_too_long and Apache SSL

As much as I have searched the web, I did not find information on how I could implement it together.  The problem is that the containers I have run on localhost:8080 and what I'm looking for is to assign a domain to it.

in a JavaScript source file and execute it, JavaScript does not interpret the 0.1 as the real number 0.1, because JavaScript numbers cannot represent every single possible real number, and 0.1 is not one of the real numbers which they can represent. Instead, 0.1 is interpreted as the closest JavaScript number to 0.1, which in binary is the number

0.0001100110011001100110011001100110011001100110011001101

0.1000000000000000055511151231257827021181583404541015625

Note that there's nothing stopping us from writing all of those decimal digits out in our JavaScript source file if we want to:

const x = 0.1000000000000000055511151231257827021181583404541015625

JavaScript will always interpret what we wrote, no matter how (im)precise, as the closest available JavaScript number. Sometimes this reinterpretation will be absolutely precise. But sometimes this reinterpretation will lose some precision.

JavaScript does not interpret this as the real number 0.2 but as the real number

0.200000000000000011102230246251565404236316680908203125

JavaScript does not interpret this as the real number 0.3 but as the real number

0.299999999999999988897769753748434595763683319091796875

(or const sum = x + y), what JavaScript actually computes is the precise sum

0.1000000000000000055511151231257827021181583404541015625 + 0.200000000000000011102230246251565404236316680908203125 = 0.3000000000000000166533453693773481063544750213623046875

JavaScript numbers cannot represent this precise result either, so the value returned is the closest available JavaScript number, which is

0.3000000000000000444089209850062616169452667236328125

Again, we have lost a little precision, although for a different reason. At first, we lost some precision in the interpretation of the source code. Now, we have lost some more precision in the calculation.

Notice that this sum value, which we got by writing 0.1 + 0.2, is a different JavaScript number from what we got when we simply typed 0.3.

Now, what happens when we try to log any of these values at the console?

JavaScript does not log every last decimal place of a number. Instead, JavaScript logs out the minimum number of digits necessary to uniquely identify that JavaScript number from the other JavaScript numbers near it.

we'll see the much shorter three-character string

at our console, because this is all that is necessary.

Note that yet again, we have lost some precision! That's three times now!

Strictly speaking, the only reason why console.log(0.1) logs 0.1 is because of two different precision-loss events which cancel one another out. There is no 0.1 in the JavaScript programming language. One would be forgiven for thinking that there is.

out. And finally, if we try to log the result of 0.1 + 0.2, which we remember is
