nginx 端口（域名、子域名）转发

1、DNS域名解析

将域名和子域名都解析到47.52.198.89上，然后通过nginx转发子域名。

2、NGINX配置文件如下

[root@ailiyunHK ~]# cat /etc/nginx/nginx.conf
# For more information on configuration, see:

include /usr/share/nginx/modules/*.conf;

    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_nodelay         on;

    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

    include /etc/nginx/conf.d/*.conf;
#博客端口为8090端口
#将所有的80端口请求转发到8090上
    server {
        listen       80 default_server;
        listen       [::]:80 default_server;
        server_name  _;
        root         /usr/share/nginx/html;

        # Load configuration files for the default server block.
        include /etc/nginx/default.d/*.conf;

        location / {

 }
#实现端口转发
#splunk 负责均衡池
upstream splunk_pool{
server 101.132.171.122:8000;
}
#实现博客端口转发
#博客服务端口为8080
upstream blog{
server localhost:8080;
}

#splunk.syhscjy.com转发配置
server {
	listen	80;
	server_name splunk.syhscjy.com;
	access_log /var/log/nginx/splunk/access.log;
	error_log /var/log/nginx/splunk/error.log;
	
	#将所有的splunk.syhscjy.com请求转发到splunk_pool池处理
	location / {
		proxy_set_header Host $host;
		proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
		proxy_pass http://splunk_pool;
	}
}
#添加子域名转发web.syhscjy.com
#静态html页面在本机上面

		root /opt/web;
	}	
	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 {
