At this time, the virtual host address added to the web page cannot be accessed , You need to add the assignment to hosts

Linux Let's designate hosts

vim /etc/hosts     edit hosts file   Add the host address , This is the time Linux Next ping  The domain name and address of the host can be accessed 

     

      
1.
     

windows Let's designate hosts

C:\Windows\System32\drivers\etc     Find this path , There's one down there hosts   Add... To it  IP Address and virtual host address 

     

      
1.
     

Now Web search virtual machine host address and IP The address is accessible

These are the default virtual hosts

Default virtual host

vim /etc/nginx/conf.d/ In the first place is the default virtual host , By default, the first one is accessed ,

It can also be set manually , For example, copy a host file

cp default.conf 123.conf There are only two virtual hosts below , When accessing, the default access is the first 123.conf

vim default.conf Edit the file in 80 Add later default_server As shown in the figure below , At this time, when visiting , It will not access the first place by default 123.conf, It's about visiting this default.conf The default host for

vim 123.conf Modify according to the following figure When the changes are complete Don't forget to use nginx -t Check to see if you can change the error , then nginx -s reload Reload profile

mkdir /tmp/html       The path modified according to the configuration file , Create a directory 
echo 123456 > /tmp/html/index.html      Create a file and import the contents 

     

      
1.
      
2.
     

Then visit... At this time www.ccc.com You can access 123456 The content of

Pan analysis

In order to restrict other domain names from being resolved to their own servers , For example, your domain name is abc.cn：

Make one *.abc.cn The secondary domain name of A The record points to 222.222.222.222, Then it takes effect when the visitor enters “123.abc.cn” still “123.123.abc.cn” It could even be “ [[email protected]#.$%$.6543.ww.a.abc.cn](http://oapage.xmisp.com/help/#.$%$.6543.ww.a.abc.cn) ” Such arbitrary characters , Can point to 222.222.222.222 This IP Address . At this time, you need to disable the default virtual host

Add a line to the configuration file As shown in the figure deny all then nginx -s reload Reload profile

At this point, accessing the default virtual host address again 403 No access .
