Nginx是一个高性能的HTTP和反向代理服务器，也是一个IMAP/POP3/SMTP服务器。在高连接并发的情况下，Nginx是Apache服务器不错的替代品：Nginx在美国是做虚拟主机生意的老板们经常选择的软件平台之一。能够支持高达50,000个并发连接数的响应，而且内存开销极小。这也是Nginx广受欢迎的重要原因。本文演示了基于Linux 6下编译安装Nginx，供大家参考。
# cat /etc/issueRed Hat Enterprise Linux Server release 6.3 (Santiago)Kernel \r on an \m# nginx -vnginx version: nginx/1.8.0
###为简化安装及配置，此处关闭了防火墙，生产环境建议开启# service iptables stop# chkconfig iptables off# vi /etc/selinux/config SELINUX=disabled###创建用户及组#groupadd -r nginx#useradd -s /sbin/nologin -g nginx -r nginx###安装环境依赖包 http://nginx.org/en/linux_packages.html# yum install pcre-devel zlib-devel openssl openssl-devel gcc gcc-c++
