Sometimes, we need to give some special access to set up a user authentication mechanism to increase security. For example, we have just installed the Discuz forum, there is a management background, although the management of the background itself has a password, but we are more secure, you can set up a layer of user authentication.
# vim/usr/local/apache2/conf/extra/httpd-vhosts.conf
In the corresponding virtual host configuration, add the following configuration:
<Directory/data/www/admin.php>
AllowOverride authconfig
AuthName "ALKSDJFLKASJDF"
AuthType Basic
authuserfile/data/.htpasswd
Require Valid-user
</Directory>
#/usr/local/apache2/bin/htpasswd-cm/data/.htpasswd 123123
/usr/local/apache2/bin/apachectl Graceful
