在/usr/local/nginx/conf目录下nginx.conf文件是nginx的配置文件。

一、通过端口号区分虚拟机
在nginx.conf文件中添加一个Service节点,修改端口号:
server {
        listen       80;
        server_name  localhost;
        #charset koi8-r;
        #access_log  logs/host.access.log  main;
        location / {
            root   html80;
            index  index.html index.htm;
        }
   }
server {
        listen       81;
        server_name  localhost;
        #charset koi8-r;
        #access_log  logs/host.access.log  main;
        location / {
            root   html81;
            index  index.html index.htm;
        }
   } 
二、通过域名区分虚拟机
①:需要修改nginx.conf配置文件
server {
        listen       80;
        server_name  test1.nginx.com;
        #charset koi8-r;
        #access_log  logs/host.access.log  main;
        location / {
            root   html-test3;
            index  index.html index.htm;
        }
   }
server {
        listen       80;
        server_name  test2.nginx.com;
        #charset koi8-r;
        #access_log  logs/host.access.log  main;
        location / {
            root   html-test3;
            index  index.html index.htm;
        }
   }
②:修改后重新加载配置文件
[root@localhost sbin]# ./nginx -s reload
至此结束……
