nginx 配置域名转发和进行ip限制

需求：公司一台服务器上使用tomcat部署了多个网站服务，服务的端口都是6080，根据不同的域名加端口6080可以对相应的服务进行访问，领导新提了个需求，在服务器上部署个nginx 实现域名转发，服务器本身只放开80端口，我们只需要域名就可以进行访问各个网站服务，同时把ip限制放在nginx里面实现。不同的服务可以限制不同的端口。

实现步骤：
一、nginx 服务的安装。
yum install nginx
二、nginx配置

user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log  error;
pid /var/run/nginx.pid;

# Load dynamic modules. See /usr/share/nginx/README.dynamic.
include /usr/share/nginx/modules/*.conf;

events {
worker_connections  1024;
}

http {
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  /var/log/nginx/access.log  main;

sendfile            on;
tcp_nopush          on;
tcp_nodelay         on;
keepalive_timeout   65;
types_hash_max_size 2048;

include             /etc/nginx/mime.types;
default_type        application/octet-stream;

# Load modular configuration files from the /etc/nginx/conf.d directory.
# See http://nginx.org/en/docs/ngx_core_module.html#include # for more information.
#include /etc/nginx/conf.d/*.conf;
server {
listen 80;
server_name www.fuweichao.com;

location / {
proxy_pass
proxy_redirect default;
proxy_set_header Host $host;    #这一行如果不设置会把域名转成ip。
deny all;
}
server {
listen 80;
server_name www.xxn.com;

location / {
proxy_pass http://www.xxn.com:9080/; proxy_redirect default;
proxy_set_header Host $host;
deny all;
}
}
