【nginx】安装与使用

ngnix简单介绍：nginx是一个轻量级，高性能的HTTP反向代理服务器，也是一个
IMAP/POP3/SMTP 代理服务器，占有内存少，并发能力强，常用作于多个项目的域名重写，中转等。

nginx下载地址：http://nginx.org/

nginx使用：下载后解压到本地磁盘下。修改config配置文件。如下：

#运行用户
#user  nobody;
#启动进程，通常设置成和CPU的数量相同。
worker_processes 1;
#全局错误日志及PID文件
error_log logs/error.log info;
pid logs/nginx.pid;

worker_rlimit_nofile 65536;

#工作模式及连接上限
events
{
	#单个后台worker process进程的最大并发连接数
	worker_connections  65536;
}

#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
{
	#设定mime类型,类型由mime.type文件定义
	include mime.types;
	default_type application/octet-stream;

	server_names_hash_bucket_size 128; 

	#sendfile 指令指定 nginx 是否调用 sendfile 函数（zero copy 方式）来输出文件，对于普通应用，
	#必须设为 on,如果用来进行下载等应用磁盘IO重负载应用，可设置为 off，以平衡磁盘与网络I/O处理速度，降低系统的uptime.
	sendfile on;
	tcp_nopush on;
	keepalive_timeout 65;
	tcp_nodelay on;

	#开启gzip压缩
	gzip on;

	#设定请求缓冲
	client_max_body_size 50m;
	fastcgi_intercept_errors on;

	proxy_buffer_size 128k;
	proxy_buffers 32 32k;
	proxy_busy_buffers_size 128k;
	fastcgi_buffer_size 128k;
	fastcgi_buffers 32 32k;

	log_format main '$remote_addr - $remote_user [$time_local] "$request" '
	    '"$http_referer" $status $body_bytes_sent $request_body '
	    '"$http_user_agent" "$http_x_forwarded_for"';

	#设定负载均衡的服务器列表
	upstream  www.test.com
	{
		server 127.0.0.1:8080;
	}

	server {
