Nginx + IIS + Web front-end (Spring MVC)-load balancing (i)

Introduction

When we were developing large Web projects, if our web was published on a single server in IIS, when a large number of request-to-IIS services were available, the computer would easily crash. So we thought, why, we don't put our services on more than one computer? So when the last request goes to 192.168.**.252:8070, we can get the next request to 192.168.**.253:8071 so that we can reduce the pressure on our servers.

Now there is a problem, how can user request send to different server? This time, you need nginx.

Now let me introduce the Web service of. NET published on Nginx.

Nginx is an unpacking package, we only need to unzip the server on Nginx, modify the configuration file, Nginx installed.

Installation and configuration of Nginx

Nginx unzip to the root directory of the C drive below:

We can see the file directory under Nginx, here we want to modify the nginx.conf file under the Conf folder:

Probably explain:

Where the file is like this:

#user nobody;worker_processes 1; #工作进程的个数, multiple #error_log Logs/error.log can be configured, #error_log logs/error.log notice; #error_ Log logs/error.log info; #pid logs/nginx.pid;events {worker_connections, #单个进程最大连接数 (maximum number of connections = number of connections * processes)} #设定htt P server, which uses its reverse proxy function to provide load Balancer support for 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 Type #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, the sendfile directive specifies whether Nginx calls the Sendfile function to output files, is set to on for normal applications, and if it is used for downloading applications such as disk IO heavy load applications, it can be switched off to balance disk and network i/ o processing speed, reducing the load on the system.    Note: If the picture does not appear normal, change this to off.    #tcp_nopush on;    #keepalive_timeout 0; Keepalive_timeout 65; #长连接超时时间, the unit is in seconds gzip on; #启用Gizp压缩 # server cluster upstream netitcast.com {#服务器集群名字 server 127.0.0.1:8030 weight=1; #服务器配 Weight is the meaning of weight, the larger the weight, the greater the probability of distribution.Server 127.0.0.1:8040 weight=1;}        #当前的Nginx的配置 server {Listen 8090; #监听80端口 can be changed to a different port server_name localhost;############# #当前服务的域名        #charset Koi8-r;        #access_log Logs/host.access.log Main;        #location/{# root HTML;        # index index.html index.htm;            #}location/{Proxy_pass http://netitcast.com;        Proxy_redirect default; } #location ~ \.

MD5;    # ssl_prefer_server_ciphers on;    # location/{# root HTML;    # index index.html index.htm; #    }    #}}

Where to modify:

#服务器的集群    upstream  netitcast.com {  #服务器集群名字  server    127.0.0.1:8030 weight=1; #服务器配置   Weight is the meaning of weight, the larger the weight, the greater the probability of distribution. Server    127.0.0.1:8040 weight=1;} #当前的Nginx的配置    Server {        listen       8090; #监听80端口, can be changed to another port        server_name  localhost;############## The domain name of the current service        #charset koi8-r;        #access_log  logs/host.access.log  main;        #location/{        #    root   html;        #    Index  index.html index.htm;        #}location/{            proxy_pass http://netitcast.com;            Proxy_redirect default;        }

We can see the name of the server cluster:

Server Ip:port

We will publish our project on that server's IP and port, and we can write the IP and port number here. The weight in the back is weighted, that is, if two servers are 1, the request is 1:1, the first request is accessed on port 8030, and the second request is accessed on port 8040.

server{Listen 8090} is the port number of the Nginx listener, which means that we can access the service in our server cluster only by accessing the IP and port number of the Nginx server.

The principle of Nginx:

Nginx configuration, in the next blog, we publish our Web services to our IIS.
