nginx

一、基本配置文件


#user  nobody;
worker_processes  1;

#错误日志存放
#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;
 error_log  /var/log/nginx/error.log;
 error_log  /var/log/nginx/error.log  notice;
 error_log  /var/log/nginx/error.log  info;

#PID标识该nginx的身份的必须配置
#pid        logs/nginx.pid;
 pid        /var/run/nginx/nginx.pid;

events {
    worker_connections  1024;
}


http {
    include       mime.types;
    default_type  application/octet-stream;

    #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;
    #tcp_nopush     on;

    #keepalive_timeout  0;
    keepalive_timeout  65;

    #gzip  on;

	#配置代理地址
	upstream proxyOne{
		server 47.106.91.91;
		server 127.0.0.1;

	}


    server {
	#监听的端口
        listen       80;
	#服务名称
        server_name  localhost;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

	
        location / {
	#配置代理地址
            proxy_pass   http://proxyOne; #会自动从上面的upstream寻找地址
            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;
    #    }
    #}


    # 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;
    #    }
    #}
}

二、负载均衡配置

nginx默认是采用轮询的方式来调用配置的服务器的,可以修改配置文件修改它的分配方式。

1、最少连接

upstream proxyOne{
		least_conn;
		server 47.106.91.91;
		server 127.0.0.1;
	}

2、按照设置的比重分配

upstream proxyOne{
		server 47.106.91.91 weight=1;
		server 127.0.0.1 weight=3;
	}

3、根据IP地址来分配

upstream proxyOne{
		ip_hash;
		server 47.106.91.91;
		server 127.0.0.1;
	}

三、nginx动静分离

配置文件:

location / {
              proxy_pass http://proxyOne;
            index  index.html index.htm;
    }
  #设置动静资源分离访问
  location ~\.(jsp|do|action)$ {
           proxy_pass  http://tomcat;
  }  
  #过滤后缀如果符合后缀   就会访问root后路径下的资源
  location ~\.(css|js|gif|jpg|png|bmp|swf)$ {
           root  /usr/local/nginx/images;
  }
