默认显示
修改后显示
1. 隐藏Apache信息
1.1 主配置中启用httpd-default.conf
文件： conf/httpd.Conf
找到httpd-default.conf，删除前面的注释“#”，改成如下
Include conf/extra/httpd-default.conf
1.2 修改httpd-default.conf
文件：conf/extra/httpd-default.conf
找到
ServerTokens Full
改成
ServerTokens Prod
找到
ServerSignature On
改成
ServerSignature off
完成
最终如下（文件：conf/extra/httpd-default.conf）
# # ServerTokens # This directive configures what you return as the Server HTTP response # Header. The default is ‘Full‘ which sends information about the OS-Type # and compiled in modules. # Set to one of: Full | OS | Minor | Minimal | Major | Prod # where Full conveys the most information, and Prod the least. # ServerTokens Prod # # Optionally add a line containing the server version and virtual host # name to server-generated pages (internal error documents, FTP directory # listings, mod_status and mod_info output etc., but not CGI generated # documents or custom error documents). # Set to "EMail" to also include a mailto: link to the ServerAdmin. # Set to one of: On | Off | EMail # ServerSignature Off
说明：
1、ServerSignature出现在Apache所产生的像404页面、目录列表等页面的底部。
2、ServerTokens目录被用来判断Apache会在Server HTTP响应包的头部填充什么信息。
如果把ServerTokens设为Prod，那么HTTP响应包头就会被设置成：Server：Apache
