nginx如何实现代理多个服务器

这篇文章给大家分享的是有关nginx如何实现代理多个服务器的内容。小编觉得挺实用的，因此分享给大家做个参考，一起跟随小编过来看看吧。

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：

然后启动nginx。

cmd下：start nginx

分别访问这两个server：

http://localhost:9922/ngtt/

http://localhost:9977/testnnnn/
