Configure apache password authentication on the CentOS Server

Apache provides a series of authentication, authorization, and access control modules. Here we use the most convenient mod_auth_basic, mod_authn_file, and mod_authz_user modules to implement directory or file authentication by entering users and passwords.
1. Generate a password file
Example:

Htpasswd-c/var/www/. htpasswd centos

/Var/www/. htpasswd is the location of the password file
Centos is an authorized user.
Htpasswd tool detailed instructions: http://lamp.linux.gov.cn/Apache/ApacheMenu/programs/htpasswd.html
2. Configure the httpd. conf file

<Directory/var/www/html/centos>
AuthType basic
AuthBasicProvider file
AuthUserFile/var/www/. htpasswd
Require valid-user
</Directory>

Authentication is required when accessing the centos directory.
