场景：在10.17.55,44:7002和10.17.55.46:7003的weblogic 部署一个web工程，准备做负载均衡。在一台IP：12.17.56.44能访问到55.44和55.46上web工程的机器做nginx代理服务器，代理端口为7000，既12.17.56.44:7000能访问到10.17.55,44:7002或10.17.55.46:7003的web工程，而互联网有个IP22.18.55.33:7000 可以访问到，12.17.56.44:7000，12.17.56.44这台服务器的nginx.conf 内容配置如下：

配置文件中：
include /etc/nginx/mutnginx/*.conf;是在mutnginx目录下，创建了两个跟nginx.conf 相似的文件。
nginx2.conf配置是为了让同个网段即12.17.56.*的其他应用能同个代理ip访问到web工程，其配置如下：
#user nobody;
worker_processes auto;
#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;
#pid logs/nginx.pid;

#thread_pool one threads=128 max_queue=0;
#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;
access_log off;
sendfile on;
#tcp_nopush on;
sendfile_max_chunk 512k;
#keepalive_timeout 0;
keepalive_timeout 65;
upstream cluster3 {
# simple round-robin
ip_hash;
server 10.17.55,44:7002;
server 10.17.55.46:7003;
}
#gzip on;
server {

server_name localhost;
# 0.99.132.52:700
#check interval=30
#charset koi8-r;
#access_log logs/host.access.log main;
location / {
#aio threads=one;
proxy_set_header Host $host:7000;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_buffering off;
proxy_pass http://cluster3/;
# root html;

}
location /status {
#check_status;

# deny all;
}
#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
#

# 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

#
#location ~ /\.ht {

}
# another virtual host using mix of IP-, name-, and port-based configuration

# ssl_ciphers HIGH:!aNULL:!MD5;
# ssl_prefer_server_ciphers on;
# location / {
# root html;
# index index.html index.htm;
# }
#}
}
还有一个nginx3.conf 是为了让，其他内网ip统一访问的代理，其配置如下：
#user nobody;
worker_processes auto;
#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;
#pid logs/nginx.pid;
events {
worker_connections 2048;
accept_mutex off;
multi_accept on;
use epoll;
}
# load modules compiled as Dynamic Shared Object (DSO)
#
#dso {
# load ngx_http_fastcgi_module.so;
# load ngx_http_rewrite_module.so;
#}
#thread_pool one threads=128 max_queue=0;
http {
include mime.types;
default_type application/octet-stream;
#thread_pool one threads=128 max_queue=0;
#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;
access_log off;
sendfile on;
#tcp_nopush on;
sendfile_max_chunk 512k;
#keepalive_timeout 0;
keepalive_timeout 65;
upstream cluster2 {
# simple round-robin
ip_hash;
server 10.17.55,44:7002;
server 10.17.55.46:7003;
}
#gzip on;
server {
listen 7000;
server_name localhost;
# 0.99.132.52:700
#check interval=30
#charset koi8-r;
#access_log logs/host.access.log main;
location / {
#aio threads=one;
proxy_set_header Host $host:5123;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_buffering off;
proxy_pass http://cluster2/;
# root html;
#index index.html index.htm;
}
location /status {
#check_status;
access_log off;
allow all;
# deny all;
}
#error_page 404 /404.html;
# redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
# proxy the PHP scripts to Apache listening on 127.0.0.1:80
#
#location ~ \.php$ {
# 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;
# server_name localhost;
# ssl on;
# ssl_certificate cert.pem;
# ssl_certificate_key cert.key;
# ssl_session_timeout 5m;
# ssl_protocols SSLv2 SSLv3 TLSv1;
# ssl_ciphers HIGH:!aNULL:!MD5;
# ssl_prefer_server_ciphers on;
# location / {
# root html;
# index index.html index.htm;
# }
#}
}
其中proxy_set_header Host $host:5123;#是映射端口，如果12.17.56.44:7000映射IP为102.34.56.44 那么5123就是映射器7000端口这样
12.17.56.44就被一个互联网IP22.18.55.33:7000 和内网12.17.56.44.：5213以及12.17.56.44:7000做了映射代理，就是这三个ip都能访问到web工程。
