采用htpasswd设置验证机制

<IfModule mod_authn_file.c>
        AuthType Basic
        AuthName "Authorization Required"
        AuthUserFile <passwordfile which is create by htpasswd cmd>
        Require valid-user
</IfModule>

windows: apache/bin/htpasswd.exe
Linux: htpasswd

Usage:
        htpasswd [-cmdpsD] passwordfile username
        htpasswd -b[cmdpsD] passwordfile username password

        htpasswd -n[mdps] username
        htpasswd -nb[mdps] username password
 -c  Create a new file.
 -n  Don’t update file; display results on stdout.
 -m  Force MD5 encryption of the password (default).
 -d  Force CRYPT encryption of the password.
 -p  Do not encrypt the password (plaintext).
 -s  Force SHA encryption of the password.
 -b  Use the password from the command line rather than prompting for it.
 -D  Delete the specified user.
On other systems than Windows, NetWare and TPF the ‘-p’ flag will probably not work.
The SHA algorithm does not use a salt and is less secure than the MD5 algorithm.
