Vim/etc/httpd/conf/httpd.conf
<directory "/westos/html" > Allow everyone to access Westos directory but deny 250 hosts
Order Allow,deny
Allow from all
Deny from 172.25.254.250
</Directory>

<directory "/westos/html" > Allow only 250 hosts to access Westos directory
Order Deny,allow
Allow from 172.25.254.250
Deny from all
</Directory>

(2) Setting user's access
Htpasswd-m/etc/httpd/accessuser Admin Create Access user authentication file (-c create-m Specify name)

Note: The first user created needs to add C, the user created later does not need to add C, directly specify-m

Create Access user admin Admin1 Specify name Authfile
