一、创建网站目录及文件:

[root@localhost data]# tree /data
/data
└── wwwroot
├── www.1.com_8080
│ └── index.html
└── www.1.com_8081
└── index.html

二、修改nginx.conf:

[root@localhost nginx]# vim /usr/local/nginx/conf/nginx.conf

worker_processes 1;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
keepalive_timeout 65;
include vhost/*.conf; #vhost目录下会包含所有的虚拟主机的配置文件
}

三、创建虚拟主机的配置文件目录:

[root@localhost conf]mkdir /usr/local/nginx/conf/vhost

四、创建虚拟主机配置文件:

[root@localhost nginx]# vim /usr/local/nginx/conf/vhost/www.1.com.8080.conf 
server{
listen 8080;
server_name 1.com www.1.com;
index index.html;
root /data/wwwroot/www.1.com_8080;
}
[root@localhost nginx]# vim /usr/local/nginx/conf/vhost/www.1.com.8081.conf  
server{
listen 8081;
server_name 1.com www.1.com;
index index.html;
root /data/wwwroot/www.1.com_8081;
}
[root@localhost nginx]# vim /usr/local/nginx/conf/vhost/default.conf          
server{
listen 80 default_server; #使用default_server指定nginx的默认虚拟主机
deny all;
}

若使用其他域名来访问虚拟主机时,会匹配到默认虚拟主机,该配置会拒绝未定义的域名的虚拟主机。若不配置该选项,默认排在最前边的server会成为默认虚拟主机。

五、测试配置文件是否存在问题:

[root@localhost root]# cd /usr/local/nginx/sbin
[root@localhost sbin]# ./nginx -t
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file

六、当配置文件修改时,可以使用一下命令重新加载配置文件

[root@localhost sbin]# ./nginx -s reload
