一、配置多个端口访问不同文件

相同域名，不同端口，不同文件

#两个不同文件夹，分别存放不同文件
[root@nginx ~]# mkdir /www/work_01 -p
[root@nginx ~]# mkdir /www/work_02
[root@nginx ~]# vim /www/work_01/index.html 
this is work_01!
[root@nginx ~]# vim /www/work_02/index.html
this is work_02!

#编辑其中server模块，把端口80的站点指向一个文件夹，再复制这个server到下面，修改端口

[root@nginx ~]# vim /usr/local/nginx/conf/nginx.conf
worker_processes  1;
events {
    worker_connections  1024;
}
http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    keepalive_timeout  65;
#80端口，指向work_01的文件夹
    server {
        listen       80;
        server_name  localhost;
        location / {
            root   /www/work_01;
            index  index.html index.htm;
        }
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
    }
#8080端口，指向work_02的文件夹
    server {
    listen 8080;
    server_name localhost;
    location / {
    root /www/work_02;
    index index.html index.htm;
    }
    error_page 500 502 503 504 /50x.html;
    location = /50x.html {
        root html;
    }
}
}

#浏览器访问

二、配置不同域名访问不同文件

相同端口，不同域名，不同文件

#四个文件夹，分别对应不同文件内容

[root@nginx ~]# cd /www/
[root@nginx www]# mkdir work_03
[root@nginx www]# mkdir work_04
[root@nginx www]# echo "This is work_03" > work_03/index.html
[root@nginx www]# echo "This is work_04" > work_04/index.html
[root@nginx www]# ls
work_01  work_02  work_03  work_04

#修改配置文件

[root@nginx www]# vim /usr/local/nginx/conf/nginx.conf
worker_processes  1;
events {
    worker_connections  1024;
}
http {
    include       mime.types;
    sendfile        on;
    keepalive_timeout  65;
#通配符在后的域名
    server {
        listen       80;
        server_name  www.haha.*;
        location / {
            root   /www/work_01;
            index  index.html index.htm;
        }
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
    }
#精确域名
    server {
    listen 80;
    server_name www.haha.com;
    location / {
    root /www/work_02;
    index index.html index.htm;
    }
    error_page 500 502 503 504 /50x.html;
    location = /50x.html {
        root html;
    }
}
#通配符在前的域名
    server {
        listen 80;
        server_name *.haha.com;
    location / {
        root /www/work_03;
        index index.html index.htm;
    }
    error_page 500 502 503 504 /50x.html;
    location = /50x.html {
        root html;
    }
}
#正则表达式域名
    server {
        listen 80;
        server_name ~w+.com;
    location / {
        root /www/work_04;
        index index.html index.htm;
    }
    error_page 500 502 503 504 /50x.html;
    location = /50x.html {
        root html;
    }
}
}
[root@nginx www]# systemctl restart nginx

#配置宿主机host文件，在"C:WindowsSystem32driversetchosts"

#访问结果

sever_name匹配顺序：

• 精准匹配

• 通配符开头，比如*.example.com

• 通配符结尾，比如www.example.*

• 正则表达式

• 默认值

三、配置不同域名访问同个文件

相同端口，不同域名 ，同个文件

[root@nginx ~]# vim /usr/local/nginx/conf/nginx.conf
worker_processes  1;
events {
    worker_connections  1024;
}
http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    keepalive_timeout  65;
#只需要在server_name再添加一个域名，不需要在复制一个server_name
    server {
        listen       80;
        server_name  www.xixi.com www.qiqi.com;
        location / {
            root   /www/work_01;
            index  index.html index.htm;
        }
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
    }
}
[root@nginx ~]# systemctl restart nginx

#该宿主机的host文件

#访问结果如下：
