【nginx】安裝與使用

ngnix簡單介紹：nginx是一個輕量級，高性能的HTTP反向代理服務器，也是一個 IMAP/POP3/SMTP 代理服務器，佔有內存少，併發能力強，常 用作於多個項目的域名重寫，中轉等。

nginx下載地址：http://nginx.org/

nginx使用：下載後解壓到本地磁盤下。修改config配置文件。如下：

#運行用戶
#user  nobody;
#啓動進程，通常設置成和CPU的數量相同。
worker_processes 1;
#全局錯誤日誌及PID文件
error_log logs/error.log info;
pid logs/nginx.pid;

worker_rlimit_nofile 65536;

#工作模式及連接上限
events 
{
	#單個後臺worker process進程的最大併發連接數
	worker_connections  65536;
}

#設定http服務器，利用它的反向代理功能提供負載均衡支持
http 
{
	#設定mime類型,類型由mime.type文件定義
	include mime.types;
	default_type application/octet-stream;
	
	server_names_hash_bucket_size 128; 

	#sendfile 指令指定 nginx 是否調用 sendfile 函數（zero copy 方式）來輸出文件，對於普通應用，
	#必須設爲 on,如果用來進行下載等應用磁盤IO重負載應用，可設置爲 off，以平衡磁盤與網絡I/O處理速度，降低系統的uptime.
	sendfile on;
	tcp_nopush on;
	keepalive_timeout 65;
	tcp_nodelay on;

	#開啓gzip壓縮
	gzip on;

	#設定請求緩衝
	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"';
