What is... Apache?
The SoftwareApache is the name of the software that allows you to run a web service on a UNIX server. Apache is very popular and provides access to most web sites on the internet. A recent Netcraft survey of Web Servers around the world placed Apache Powered sites at over 50 percent of the total. Part of the reason for this maybe that it is freely available, reliable and simple to set up and configure, and it can provide most of the requirements for a web site.

        Why is Apache Free?
One of the reasons Apache is free is because it is written and maintained by enthusiasts and volunteers, much in the spirit of many UNIX users. It is distributed under the GNU public licence, which means it can be compiled for free on any UNIX platform, including LINUX (Which is a UNIX platform for the PC.) The Apache group work under an open philosophy: the software is written by volunteers which enables it to be distributed free of charge. The underlying belief is that the Internet should remain an open and global system of communication, not `owned' by any one company. This will help to maintain the philosophy with which the web was originaly created and to keep tools for online publishing in the hands of everyone.

       Additionally Apache benefits from being an open system in that its users often contribute to it, by writing enhancements, bug fixes, or writing documentation. Potentially anyone in the world can add improvements to the Apache server. In practice the contribution by individuals is fairly slim, however, because the development of the software is carefully monitored to ensure its robustness. But it does mean that Apache ( as with any `freeware') develops organically and by its end-users. This can't neccesarily be said about commercial software.

       Apache是一款软件的名称,让您运行的WebService在UNIX伺服器. Apache是非常流行的,并为许多的因特网网站提供服务. 最近netcraft调查全世界放置阿帕奇Web伺服器超过总数的50%份额。部分原因可能在于,它是免费的,可靠和简单的设置和配置,同时它可提供满足大多数网站要求.

为什么是Apache免费的?
       原因之一,Apache是免费的,就是因为它是爱好者和志愿者的编写,很多Unix用户.它是分布式的GNU公共许可,这意味着它可为无任何Unix平台,包括Linux(这是一个Unix平台为PC).Apache的工作小组，一个开放的哲学:本软件是由志愿者编写并使它能够免费分发. 基本信念是,因特网应是一个开放的全球系统的交流,不`属于'任何一家公司. 这将有助于保持哲学与该网站原本是创造和保持工具在线发发布在每个人的手中.

      此外阿帕奇受益,作为一个开放的系统,其用户常常为它作贡献,以编写性更强的enhancements, bug fixes,或以书面文件. 在的世界上的任何人可以补充改进Apache服务器. 在实践中作出贡献的个人,是相当渺小,不过,由于软件的开发是认真监督,以确保其稳健. 但是,这并不意味着阿帕奇(如同任何'freeware')开发有机结合和它的最终用户. 这也不能说是商业软件.
