1. http2.4.1

The first outright denial of access

Open the httpd.conf file and append the configuration under 1 to the end of the file. 


<pre name="code" class="html"><pre name="code" class="html"><pre name="code" class="html"># Reject all illegal domain names directly 
<VirtualHost *:80>
  ServerName *
  ServerAlias *
  <Location />
    Order Allow,Deny
    Deny from all
  </Location>
  ErrorLog "/alidata/log/httpd/error.log"
  CustomLog "/alidata/log/httpd/info.log" common
</VirtualHost>
</pre><pre name="code" class="html"><pre name="code" class="html"># Permitted domain names 
<VirtualHost *:80>
  DocumentRoot /alidata/www
  ServerName www. Your domain name 
  ServerAlias www. Your domain name 
  <Directory "/alidata/www">
    Options Indexes FollowSymLinks
    AllowOverride all
    Order allow,deny
    Allow from all
  </Directory>
  <IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteRule ^(.*)-htm-(.*)$ .php?
    RewriteRule ^(.*)/simple/([a-z0-9\_]+\.html)$ /simple/index.php?
  </IfModule>
  ErrorLog "/alidata/log/httpd/error.log"
  CustomLog "/alidata/log/httpd/info.log" common
</VirtualHost>

Restart apache service: service httpd restart

Second, it jumps to a specified directory or file

Open the httpd. conf file and append the configuration under 1 to the end of the file. 


# All illegal domain names redirect to the specified directory or file 
<pre name="code" class="html"><pre name="code" class="html"><VirtualHost *:80>
# Specify a directory or file 
  DocumentRoot "/yun/www"
  ServerName *
  ServerAlias *
</VirtualHost>
</pre><pre name="code" class="html"><pre name="code" class="html"># Permitted domain names 
<VirtualHost *:80>
  DocumentRoot /alidata/www/fdt
  ServerName www.fdt-art.com
  ServerAlias www.fdt-art.com
  <Directory "/alidata/www/fdt">
    Options Indexes FollowSymLinks
    AllowOverride all
    Order allow,deny
    Allow from all
  </Directory>
  <IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteRule ^(.*)-htm-(.*)$ .php?
    RewriteRule ^(.*)/simple/([a-z0-9\_]+\.html)$ /simple/index.php?
  </IfModule>
# The error log 
  ErrorLog "/alidata/log/httpd/error.log"
  CustomLog "/alidata/log/httpd/info.log" common
</VirtualHost>

Restart the apache service: service httpd restart

2. http2.4.1 After:

http 2.4.1 NameVirtualHost is no longer required and ServerName * is no longer supported.

Use ServerName * to report to Invalid ServerName "*" use ServerAlias set multiple server names.

Type 1: Outright rejection

Open httpd.conf and add the following code at the end of the file: 


<pre name="code" class="html"><pre name="code" class="html"># Ban all illegal domain names 
<VirtualHost *:80>
  ServerName  The server ip
  ServerAlias *
  <Location />
    Order Allow,Deny
    Deny from all
  </Location>
</VirtualHost>
<pre name="code" class="html"># The domain name to which access is allowed 
<VirtualHost *:80>
  DocumentRoot /alidata/www
  ServerName www. Your domain name 
  ServerAlias www. Your domain name 
  <Directory "/alidata/www">
    Options Indexes FollowSymLinks
    AllowOverride all
    Order allow,deny
    Allow from all
  </Directory>
  <IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteRule ^(.*)-htm-(.*)$ .php?
    RewriteRule ^(.*)/simple/([a-z0-9\_]+\.html)$ /simple/index.php?
  </IfModule>
# Error log save location 
  ErrorLog "/alidata/log/httpd/error.log"
  CustomLog "/alidata/log/httpd/info.log" common
</VirtualHost>

Restart the apache service: service httpd restart

Type 2: Jumps to a specified directory or file

Open ES65en. conf and add the following code at the end of the file: 


<pre name="code" class="html"><pre name="code" class="html"># Ban all illegal domain names 
<VirtualHost *:80>
  DocumentRoot "/alidata/www"
  ServerName  The server ip
  ServerAlias *
  <Location /alidata/www>
    Order Allow,Deny
    Allow from all
  </Location>
</VirtualHost>
</pre>
<pre name="code" class="html"># The domain name to which access is allowed 
<VirtualHost *:80>
  DocumentRoot /alidata/www/fdt
  ServerName www.fdt-art.com
  ServerAlias www.fdt-art.com
  <Directory "/alidata/www/fdt">
    Options Indexes FollowSymLinks
    AllowOverride all
    Order allow,deny
    Allow from all
  </Directory>
  <IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteRule ^(.*)-htm-(.*)$ .php?
    RewriteRule ^(.*)/simple/([a-z0-9\_]+\.html)$ /simple/index.php?
  </IfModule>
# Error log save location 
  ErrorLog "/alidata/log/httpd/error.log"
  CustomLog "/alidata/log/httpd/info.log" common
</VirtualHost>
