It was inspired by the following: Convenience It is often inconvenient to need to write rc. Supervisord starts processes as its subprocesses, and can be configured to automatically restart them on a crash.
Linux Linux is a Unix-like computer operating system assembled under the model of free and open-source software development and distribution. Most Linux distributionsas collections of software based around the Linux kernel and often around a package management systemprovide complete LAMP setups through their packages.
According to W3Techs in October In JuneNetcraft estimated that Apache served Released under the Apache LicenseApache is open-source software.
A wide variety of features are supported, and many of them are implemented as compiled modules which extend the core functionality of Apache. These can range from server-side programming language support to authentication schemes.
MySQL and alternatives[ edit ] Main articles: MongoDB is a web-scale open-source NoSQL database that eschews the traditional table-based relational database structure in favor of JSON -like documents with dynamic schemas calling the format BSONmaking the integration of data in certain types of applications easier and faster.
PHP and alternatives[ edit ] Main articles: PHP is a server-side scripting language designed for web development but also used as a general-purpose programming language.
PHP code is interpreted by a web server via a PHP processor module, which generates the resulting web page. PHP commands can optionally be embedded directly into an HTML source document rather than calling an external file to process data.
It has also evolved to include a command-line interface capability and can be used in standalone graphical applications. The languages in this family include Perl 5 and Perl 6.
Perl 5 gained widespread popularity in the late s as a CGI scripting language for the Web, in part due to its parsing abilities.
It features a dynamic type system, automatic memory managementa standard libraryand strict use of whitespace.
High availability and load balancing[ edit ] Main articles: High availabilityLoad balancingand Replication Specific solutions are required for websites that serve large numbers of requests, or provide services that demand high uptime.
High-availability approaches for the LAMP stack may involve multiple web and database servers, combined with additional components that perform logical aggregation of resources provided by each of the servers, as well as distribution of the workload across multiple servers.
The aggregation of web servers may be provided by placing a load balancer in front of them, for example by using Linux Virtual Server LVS.
Such redundant setups may also handle hardware failures resulting in data loss on individual servers in a way that prevents collectively stored data from actually becoming lost.I'm a learning programmer and I've run into a bit of a jumble.
I am asked to write a program that will compute and display Fibonacci's Sequence by a user inputted start number and end number (ie.
startNumber = 20 endNumber = and it will display only the numbers between that range). “Think about the ideal way to write a web app. Write the code to make it happen.”. Support module for Common Gateway Interface (CGI) scripts.
This module defines a number of utilities for use by CGI scripts written in Python. I'm trying to create a simple http server with basic GET and POST functionality. The program is supposed to GET requests by printing out a simple webpage that greets a user and askes how he would r.
With Django, you don’t do that. It’s not a good idea to put any of this Python code within your Web server’s document root, because it risks the possibility that people may be able to view your code over the Web. That’s not good for security. Write your first view. Python Security is a free, open source, OWASP project that aims at creating a hardened version of python that makes it easier for security professionals and developers to write applications more resilient to attacks and manipulations.
The project is designed to explore how web applications can be developed in python by approaching the problem from three different angles.
