一、前言
Nginx ("engine x") 是一个高性能的HTTP和反向代理服务器，也是一个IMAP/POP3/SMTP代理服务器。Nginx是由Igor Sysoev为俄罗斯访问量第二的Rambler.ru 站点开发的，第一个公开版本0.1.0发布于2004年10月4日。其将源代码以类BSD许可证的形式发布，因它的稳定性、丰富的功能集、示例配置文件和低系统资源的消耗而闻名。其特点是占有内存少，并发能力强，事实上nginx的并发能力确实在同类型的网页服务器中表现较好，中国大陆使用nginx网站用户有：新浪、网易、 腾讯等。
Nginx 是一个很强大的高性能Web和反向代理服务器，它具有很多非常优越的特性：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，感谢Nginx为我们选择了 epoll and kqueue作为开发模型。
二、环境
系统：CentOS6.4 32位
源码包：
nginx-1.4.4.tar.gz

libevent-2.0.21-stable.tar.gz
三、配置
1.安装libevent

# rpm -qa |grep libevent
libevent-1.4.13-4.el6.i686
# yum remove libevent
# tar -zxvf libevent-2.0.21-stable.tar.gz -C /usr/local/src/
# cd /usr/local/src/libevent-2.0.21-stable/
# ./configure --prefix=/usr/local/libevent
# make && make install
# cd /usr/local/libevent/
# cd lib/
# ll
# vim /etc/ld.so.conf.d/libevent.conf
# ldconfig
# ldconfig  -pv |grep libevent
libevent_pthreads-2.0.so.5 (libc6) => /usr/local/libevent/lib/libevent_pthreads-2.0.so.5
libevent_extra-2.0.so.5 (libc6) => /usr/local/libevent/lib/libevent_extra-2.0.so.5
libevent_core-2.0.so.5 (libc6) => /usr/local/libevent/lib/libevent_core-2.0.so.5
libevent-2.0.so.5 (libc6) => /usr/local/libevent/lib/libevent-2.0.so.5

2.安装pcre-devel和openssl-devel

# rpm -qa |grep pcre
pcre-7.8-6.el6.i686
# yum install pcre-devel -y
# rpm -qa |grep openssl
openssl-1.0.0-27.el6.i686
# yum install openssl-devel -y

3.创建组和账号

# groupadd -r nginx
# useradd -r -g nginx -s /sbin/nologin -M nginx

4.安装nginx

# yum remove httpd
# setenforce 0       //尽量关闭防火墙和SELinux
# tar -zxvf nginx-1.4.4.tar.gz -C /usr/local/src/nginx-1.4.4/
# ./configure \

# service nginx restart

四、测试
1.简单测试
客户机访问http://192.168.2.10



2.基于地址的虚拟主机测试

# cd /usr/local/nginx/
# echo 'Welcome to www.nuo.com' >html/index.html
# mkdir tec
# echo 'Welcome to tec.nuo.com!' >tec/index.html
# ifconfig eth0:1 192.168.2.20                   //添加临时地址
# vim /etc/nginx/nginx.conf
36     server {
37         listen       192.168.2.10:80;
38         server_name  www.nuo.com;
81     server {                               //复制36-80行内容
82         listen       192.168.2.20:80;
83         server_name  tec.nuo.com;
84
85         #charset koi8-r;
86
87         #access_log  logs/host.access.log  main;
88
89         location / {
90             root   tec;
91             index  index.html index.htm;
92         }
93         access_log  /var/log/nginx/tec_log;
94         error_log   /var/log/nginx/tec_err_log;
95         #error_page  404              /404.html;
96
97         # redirect server error pages to the static page /50x.html
98         #
99         error_page   500 502 503 504  /50x.html;
100         location = /50x.html {
101             root   html;
102         }
# service nginx configtest
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
# service nginx restart
# netstat -tupln |grep nginx
tcp        0      0 192.168.2.20:80             0.0.0.0:*                   LISTEN      15284/nginx
tcp        0      0 192.168.2.10:80             0.0.0.0:*                   LISTEN      15284/nginx
//客户机hosts文件设置
192.168.2.10           www.nuo.com
192.168.2.20           tec.nuo.com

3.基于端口的虚拟主机

# vim /etc/nginx/nginx.conf
82         listen       192.168.2.10:800;
83         server_name  www.nuo.com;
# service nginx restart
# netstat -tupln |grep nginx
tcp        0      0 192.168.2.10:80             0.0.0.0:*                   LISTEN      15468/nginx
tcp        0      0 192.168.2.10:800            0.0.0.0:*                   LISTEN      15468/nginx
//客户机hosts文件设置
192.168.2.10           www.nuo.com

4.基于主机头的访问

# vim /etc/nginx/nginx.conf
82         listen       192.168.2.10:80;
83         server_name  tec.nuo.com;
# service nginx restart
//客户机hosts文件设置
192.168.2.10           www.nuo.com
192.168.2.10           tec.nuo.com

5.物理目录

# cd /usr/local/nginx/html
# mkdir abc
# echo 'This is real dir' >abc/index.html

6.虚拟目录

# vim /etc/nginx/nginx.conf              //添加48-51行内容
48         location /public {
49             alias   /abc;
50             index  index.html index.htm;
51         }
# service nginx restart
