Linux（CentOS）环境下安装下载Nginx并配置
<p><strong>1、准备工作</strong></p>
<p>
选首先安装这几个软件：GCC，PCRE（Perl Compatible Regular Expression），zlib，OpenSSL。</p>
<p>
Nginx是C写的，需要用GCC编译；Nginx的Rewrite和HTTP模块会用到PCRE；Nginx中的Gzip用到zlib；</p>
<p>
用命令“# gcc”，查看gcc是否安装；如果出现“gcc: no input files”信息，说明已经安装好了。</p>
<p>
否则，就需要用命令“# yum install gcc”，进行安装了！一路可能需要多次输入y，进行确认。</p>
<p>
安装好后，可以再用命令“#gcc”测试，或者用命令“# gcc -v”查看其版本号。</p>
<p>
同样方法，用如下命令安装PCRE，zlib，OpenSSL（其中devel，是develop开发包的意思）：</p>

<strong>2、下载并安装</strong></p>
<p>
创建目录（nginx-src）并进去；然后，从官方地址（http://nginx.org/）下载，解压，配置，编译，安装：</p>
