为了防止恶意域名绑定到自己的服务器ip上以及直接通过ip访问方式访问。我们可以通过apache配置可以实现这一目的,具体操作步骤如下。
第一步,httpd.conf配置设置
启用虚拟主机、ssl、重写模块
LoadModule vhost_alias_module modules/mod_vhost_alias.so
LoadModule rewrite_module modules/mod_rewrite.so
LoadModule ssl_module modules/mod_ssl.so
禁用根目录访问
    AllowOverride None
    Require all denied
允许htdocs目录访问
DocumentRoot "/usr/local/httpd/htdocs"
    #
    # Possible values for the Options directive are "None", "All",
    # or any combination of:
    #   Indexes Includes FollowSymLinks SymLinksifOwnerMatch ExecCGI MultiViews
    #
    # Note that "MultiViews" must be named 
explicitly --- "Options All"
    # doesn't give it to you.
    #
    # The Options directive is both complicated and important.  Please see
    # 
http://httpd.apache.org/docs/2.4/mod/core.html#options    # for more information.
    #
    Options Indexes FollowSymLinks
    #
    # AllowOverride controls what directives may be placed in .htaccess files.
    # It can be "All", "None", or any combination of the keywords:
    #   AllowOverride FileInfo AuthConfig Limit
    #
    # cache
    AllowOverride None
    #
    # Controls who can get stuff from this server.
    #
    Require all denied
