Nginx 的配置及配置文件部分介绍

一、官网下载

http://nginx.org/download/

选择你自己想要的版本下载，解压 nginx（例如nginx-1.6.3）

执行下列操作：（需要记住的，会经常用到）

nginx -s stop          // 停止nginx
nginx -s reload       // 重新加载配置文件
nginx -s quit          // 退出nginx

二、配置 Nginx

接下来就是配置 Nginx 的 conf 文件了。Nginx 需要配置的东西也就是在 conf 文件中，现在介绍下了解下 conf 文件的配置：

#user nobody;
worker_processes 2;   #进程数，初始可设置为cpu总核数

#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;

#pid logs/nginx.pid;  #用于管理nginx进程


events {
	worker_connections 1024; #单个worker进程最大连接数
}

http {    
	include mime.types; #文件扩展名与文件类型映射表
	default_type application/octet-stream; #默认文件类型
	
	#log_format main '$remote_addr - $remote_user [$time_local] "$request" '
	# '$status $body_bytes_sent "$http_referer" '
	# '"$http_user_agent" "$http_x_forwarded_for"';
	
	#access_log logs/access.log main;
	
	sendfile on;   #开启高效文件传输模式，实现内核零拷贝
	#tcp_nopush on;
	
	#keepalive_timeout 0;
	keepalive_timeout 65; #连接超时时间，单位是秒
	
	#gzip on;
	
	server {
	listen 8089;  #连接的端口号
	server_name localhost;
	autoindex on;
	#charset koi8-r;
	
	#access_log logs/host.access.log main;
	#下面的就是你接收传输文件的格式要求了，根据你的需要来用，下面我使用来接收图片（jpg...）
	location ~ .*\.(gif|jpg|jpeg|png|bmp)$ { 
	
		expires 24h; #客户端缓存上述静态数据
		root C:/resources/images/;  #文件路径
		access_log C:/nginx-1.6.3/logs/log_test.log;
		proxy_store on; 
		proxy_store_access user:rw group:rw all:rw; 
		proxy_temp_path C:/resources/images/;#文件路径
		proxy_redirect off; 
		
		#autoindex on;
		proxy_set_header Host 127.0.0.1; #填写你的ip
		proxy_set_header X-Real-IP $remote_addr; 
		proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; 
		client_max_body_size 10m; 
		client_body_buffer_size 1280k; 
		proxy_connect_timeout 900; 
		proxy_send_timeout 900; 
		proxy_read_timeout 900; 
		proxy_buffer_size 400k; 
		proxy_buffers 40 320k; 
		proxy_busy_buffers_size 640k; 
		proxy_temp_file_write_size 640k; 
		if ( !-e $request_filename) 
		{ 
			proxy_pass http://127.0.0.1:8089;  
		} 
	}
	
	#下面是我拿来传输mp3格式的配置
	location ~* .(mp3)$ {
		expires 24h; 
		root C:/resources/voice/; #文件路径
		proxy_store on; 
		proxy_store_access user:rw group:rw all:rw; 
		proxy_temp_path C:/resources/voice/;#文件路径
		proxy_redirect off; 
		
		proxy_set_header Host 127.0.0.1; 
		proxy_set_header X-Real-IP $remote_addr; 
		proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; 
		client_max_body_size 10m; 
		client_body_buffer_size 1280k; 
		proxy_connect_timeout 900; 
		proxy_send_timeout 900; 
		proxy_read_timeout 900; 
		proxy_buffer_size 40k; 
		proxy_buffers 40 320k; 
		proxy_busy_buffers_size 640k; 
		proxy_temp_file_write_size 640k; 
		if ( !-e $request_filename) 
		{ 
			proxy_pass http://127.0.0.1:8089 ; 
		} 
	}
	
	location / {
		root html;
		index index.html index.htm;
	}
	
	#error_page 404 /404.html;
	
	# redirect server error pages to the static page /50x.html
	#
	error_page 500 502 503 504 /50x.html;
	location = /50x.html {
		root html;
	}
	
	# proxy the PHP scripts to Apache listening on 127.0.0.1:80
	#
	#location ~ \.php$ {
	# proxy_pass http://127.0.0.1;
	#}
	
	# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
	#
	#location ~ \.php$ {
	# root html;
	# fastcgi_pass 127.0.0.1:9000;
	# fastcgi_index index.php;
	# fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;
	# include fastcgi_params;
	#}
	
	# deny access to .htaccess files, if Apache's document root
	# concurs with nginx's one
	#
	#location ~ /\.ht {
	# deny all;
	#}
	}
	
	# another virtual host using mix of IP-, name-, and port-based configuration
	#
	#server {
	# listen 8000;
	# listen somename:8080;
	# server_name somename alias another.alias;
	
	# location / {
	# root html;
	# index index.html index.htm;
	# }
	#}
	
	#下面是配置https
	# HTTPS server
	#
	#server {
	# listen 443 ssl;
	# server_name localhost;
	
	# ssl_certificate cert.pem;
	# ssl_certificate_key cert.key;
	
	# ssl_session_cache shared:SSL:1m;
	# ssl_session_timeout 5m;
	
	# ssl_ciphers HIGH:!aNULL:!MD5;
	# ssl_prefer_server_ciphers on;
	
	# location / {
	# root html;
	# index index.html index.htm;
	# }
	#}
}

三. 注意事项

会遇到的问题：

1. 配置完 conf 后，你启动 nginx 启动不了，说明是你 conf 文件配置有错误，你需要回去检查下。比如 {} 少了，文件路径名不对等等。

2. 有时会根据需要用到 http 和 https，整个配置文件你只需要配置到 http {} 里面和 https{} 里面的东西就行。
