在阿里云服务器的域名解析里添加你要增加的子域名主机记录

然后在centos 的Nginx 配置中，增加子域名解析

如果你解析的是本地IP端口地址

server { 

listen       80; 

server_name  B.ABC.com; 

location / { 
proxy_pass http://localhost:4321; 
//设置主机头真实IP地址的用户避免获得为代理服务器的地址
proxy_set_header   Host    $host; 

proxy_set_header   X-Real-IP   $remote_addr; 

proxy_set_header   X-Forwarded-For $proxy_add_x_forwarded_for; 

    } 

}

如果你解析的是目录网页

#MY CONFIG START
server
{
listen   80;
server_name  qq.com;
  root   /usr/share/nginx/html;
    index  index.php index.html index.htm;
    location ~ \.php$ {
include /etc/nginx/fastcgi_params;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
}
}
#先配置的是qq.com,相信我有配置这个的必要性，location里面的是为了让我们的Nginx服务器知道.php文件要去找php解释器执行，不配置可能会出现访问即下载文件的现象
#不要问我为什么，我是抄上面那个默认的server的，错不了，手动滑稽
server
{
    listen   80;
    server_name   blog.qq.com;
    root   /usr/share/nginx/html/blog;
    index  index.php index.html index.htm;
    location ~ \.php$ {
include /etc/nginx/fastcgi_params;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
}
}
#MY CONFIG END

centos下使用iptables开放22，80，3306端口的方法

vi /etc/sysconfig/iptables 
-A INPUT -m state –state NEW -m tcp -p tcp –dport 80 -j ACCEPT（允许80端口通过防火墙） 
-A INPUT -m state –state NEW -m tcp -p tcp –dport 3306 -j ACCEPT（允许3306端口通过防火墙） 
特别提示：很多网友把这两条规则添加到防火墙配置的最后一行，导致防火墙启动失败，正确的应该是添加到默认的22端口这条规则的下面

添加好之后防火墙规则如下所示：
###################################### 
# Firewall configuration written by system-config-firewall 
# Manual customization of this file is not recommended. 
*filter 
:INPUT ACCEPT [0:0] 
:FORWARD ACCEPT [0:0] 
:OUTPUT ACCEPT [0:0] 
-A INPUT -m state –state ESTABLISHED,RELATED -j ACCEPT 
-A INPUT -p icmp -j ACCEPT 
-A INPUT -i lo -j ACCEPT 
-A INPUT -m state –state NEW -m tcp -p tcp –dport 22 -j ACCEPT 
-A INPUT -m state –state NEW -m tcp -p tcp –dport 80 -j ACCEPT 
-A INPUT -m state –state NEW -m tcp -p tcp –dport 3306 -j ACCEPT 
-A INPUT -j REJECT –reject-with icmp-host-prohibited 
-A FORWARD -j REJECT –reject-with icmp-host-prohibited 
COMMIT 
#####################################
/etc/init.d/iptables restart  
     #最后重启防火墙使配置生效

使用http://tool.chinaz.com/port/来检测是否开放成功
