# nginx 代理多个服务器——多个server方式 #

上一篇文章（http://blog.csdn.net/wild46cat/article/details/52840125）介绍了nginx的基本配置和使用方法，并且简单的介绍了一下如何利用nginx结合tomcat进行使用，达到反向代理的作用。现在我们要使用nginx达到这样的一个目的，能够代理多个服务器。

首先修改配置文件：

#user  nobody;
    worker_processes  1;
    
    #error_log  logs/error.log;
    #error_log  logs/error.log  notice;
    #error_log  logs/error.log  info;
    
    #pid        logs/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;
    
        server {
            listen       9922;
            server_name  firstProxyServer;
    
            #charset koi8-r;
    
            #access_log  logs/host.access.log  main;
    
            #location / {
               #root   html;
                #index  index.html index.htm;
            #}
    		location / {
                proxy_pass http://localhost:8989;
            }
    
            #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;
            #}
        }
    
    	 server {
            listen       9977;
            server_name  secondProxyServer;
    
            #charset koi8-r;
    
            #access_log  logs/host.access.log  main;
    
            #location / {
               #root   html;
                #index  index.html index.htm;
            #}
    		location / {
                proxy_pass http://localhost:8080;
            }
    
            #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;
        #    }
        #}
    
    }

其中主要的是有两个server，每个server对应的被代理的服务器的不同。从而实现了nginx代理多个服务器的目的。

下面是两个服务server的配置：

server {
            listen       9922;
            server_name  firstProxyServer;
    
            #charset koi8-r;
    
            #access_log  logs/host.access.log  main;
    
            #location / {
               #root   html;
                #index  index.html index.htm;
            #}
    		location / {
                proxy_pass http://localhost:8989;
            }
    
            #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;
            #}
        }
    
    	 server {
            listen       9977;
            server_name  secondProxyServer;
    
            #charset koi8-r;
    
            #access_log  logs/host.access.log  main;
    
            #location / {
               #root   html;
                #index  index.html index.htm;
            #}
    		location / {
                proxy_pass http://localhost:8080;
            }
    
            #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;
            #}
        }

下面是测试的结果：

首先两个tomcat中部署两个服务器：

![Center][]

![Center 1][]

然后启动nginx。

cmd下：start nginx

分别访问这两个server：

http://localhost:9922/ngtt/

![Center 2][]

http://localhost:9977/testnnnn/

![Center 3][]
