Nginx在Windows2003底下做端口转发，解决80端口被封

Windows下面操作的整体流程：

下载Nginx--》解压——》修改nginx.conf--》添加proxy.conf文件--》双击启动Nginx.exe即可！

1、Win下载：nginx-0.8.31 ，地址：http://sysoev.ru/nginx/nginx-0.8.31.zip

添加的proxy.conf 文件中加入如下内容： 

proxy_redirect off; 
proxy_set_header Host $host; 
proxy_set_header X-Real-IP $remote_addr; 
proxy_set_header REMOTE-HOST $remote_addr; 
proxy_set_header X-Forwarded-For $remote_addr; 
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; 
client_max_body_size 10m; 
client_body_buffer_size 128k; 
# client_body_temp_path /var/nginx/client_body_temp; 
proxy_connect_timeout 90; 
proxy_send_timeout 90; 
proxy_read_timeout 90; 
#proxy_send_lowat 12000; 
proxy_buffer_size 32k; 
proxy_buffers 4 32k; 
proxy_busy_buffers_size 64k; 
proxy_temp_file_write_size 64k; 
# proxy_temp_path /var/nginx/proxy_temp; 
proxy_ignore_client_abort on; 
proxy_next_upstream error timeout invalid_header http_500 http_503 http_404; 
proxy_max_temp_file_size 128m;

nginx.conf内容修改如下：

#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; 
include proxy.conf; 
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 80; 
server_name localhost; 

#charset koi8-r; 

#access_log logs/host.access.log main; 

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

#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 ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP; 
# ssl_prefer_server_ciphers on; 

# location / { 
# root html; 
# index index.html index.htm; 
# } 
#} 
# 根据您主机的情况按照下面的格式 一行一个站 ，一个站对一个端口 ，端口请不要重复，否则你的IIS可能启动不了！ 
server { listen 80; server_name ww1.sample.com; location / { proxy_pass http://118.18.188.211:81; }}
server { listen 80; server_name ww2.sample.com; location / { proxy_pass http://128.18.182.21:82; }}
}

随便找一个没封80端口的VPS或者独立主机就行了，计算机内有655535个端口，你可以随便设置，让封80端口没意义吧！

PS：顺便可以高级配置一下Nginx，然它能够帮你负载一下图片，css等固定的资源，作为前段cache也是相当的不错的！
