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。2011年6月1日,nginx 1.0.4发布。



一般我们都需要先装pcre, zlib,前者为了重写rewrite,后者为了gzip压缩。
1.选定源码目录
选定目录 /usr/local/

cd /usr/local/

2.安装PCRE库
cd /usr/local/
wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.21.tar.gz
tar -zxvf pcre-8.21.tar.gz
cd pcre-8.21
./configure
make
make install

3.安装zlib库
cd /usr/local/
wget http://zlib.net/zlib-1.2.8.tar.gz
tar -zxvf zlib-1.2.8.tar.gz cd zlib-1.2.8
./configure
make
make install

4.安装ssl

cd /usr/local/
wget http://www.openssl.org/source/openssl-1.0.1c.tar.gz
tar -zxvf openssl-1.0.1c.tar.gz
./config
make
make install

5.安装nginx

Nginx 一般有两个版本,分别是稳定版和开发版,您可以根据您的目的来选择这两个版本的其中一个,下面是把 Nginx 安装到 /usr/local/nginx 目录下的详细步骤:

cd /usr/local/
wget http://nginx.org/download/nginx-1.2.8.tar.gz
tar -zxvf nginx-1.2.8.tar.gz
cd nginx-1.2.8  
./configure --prefix=/usr/local/nginx
make
make install

--with-pcre=/usr/src/pcre-8.21 指的是pcre-8.21 的源码路径。
--with-zlib=/usr/src/zlib-1.2.7 指的是zlib-1.2.7 的源码路径。

6.启动
确保系统的 80 端口没被其他程序占用,
/usr/local/nginx/sbin/nginx

检查是否启动成功:
netstat -ano|grep 80 有结果输入说明启动成功


打开浏览器访问此机器的 IP,如果浏览器出现 Welcome to nginx! 则表示 Nginx 已经安装并运行成功。

7.重启
/usr/local/nginx/sbin/nginx –s reload

8.修改配置文件
cd /usr/local/nginx/conf
vi nginx.conf

9.常用配置
#nginx运行用户和组
user    www www;  
#启动进程,通常设置成和cpu的数量相等
worker_processes  4;

#全局错误日志及PID文件
pid /var/run/nginx.pid;
error_log  /var/log/nginx/error.log;

events {
        #epoll是多路复用IO(I/O Multiplexing)中的一种方式,但是仅用于linux2.6以上内核,可以大大提高nginx的性能
use epoll;
                   #单个后台worker process进程的最大并发链接数
        worker_connections  10240;
}
#设定http服务器,利用它的反向代理功能提供负载均衡支持
http {

         error_page 400 403 500 502 503 504  /50x.html;

         fastcgi_intercept_errors on;

        sendfile        on;

        # These are good default values.
        tcp_nopush      on;
        tcp_nodelay     off;
