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 （解压后的文件路径）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;

}
