详解nginx 代理多个服务器(多个server方式)

上一篇文章介绍了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;

#pidlogs/nginx.pid;


events {
worker_connections 1024;
}


http {
includemime.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;

sendfileon;
#tcp_nopushon;

#keepalive_timeout 0;
keepalive_timeout 65;

#gzip on;

server {
listen9922;
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;
# includefastcgi_params;
#}

# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#
#location ~ /\.ht {
# deny all;
#}
}

server {
listen9977;
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;
# includefastcgi_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 {
# listen8000;
# listensomename:8080;
# server_name somename alias another.alias;

# location / {
#root html;
#index index.html index.htm;
# }
#}


# HTTPS server
#
#server {
# listen443 ssl;
# server_name localhost;

# ssl_certificatecert.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 {
listen9922;
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;
# includefastcgi_params;
#}

# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#
#location ~ /\.ht {
# deny all;
#}
}

server {
listen9977;
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;
# includefastcgi_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/
