How to configure the apache server globally, I believe many inexperienced people are at a loss about this. Therefore, this paper summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

Apache server global configuration details, introduce a lot of server-related knowledge.

Server identity configuration for global configuration of Apache server

Server identity related instructions:

ServerName

ServerAdmin

ServerSignature

ServerTokens

UseCanonicalName

UseCanonicalPhysicalPort

The ServerAdmin and ServerTokens directives control which information about the server will appear in the documents generated by the server, such as error messages. The ServerTokens directive sets the value of the server HTTP response header field.

The ServerName, UseCanonicalName, and UseCanonicalPhysicalPort instructions are used to determine how to build a self-referenced URL. For example, if a client requests a directory but does not include the last slash "/" of the directory name, Apache redirects the client to the full name that contains "/" so that the client can correctly resolve the relative references in the document.

ServerName instruction

Syntax: ServerName [scheme://] FQDN [: port]

This directive is used to set the hostname and port number that the server uses to identify itself. Mainly used to create a redirect URL.

For example, your web server's hostname is example.bob.com, but your web server also has a DNS alias www.bob.com in the DNS server. If you want the web server to be more significant, you can use the ServerName directive in http.conf to do this:

ServerName www.bob.com:80

When no ServerName is specified, the server attempts to reverse query the IP address to infer the hostname. If no port number is specified in ServerName, the server listens on all ports. To enhance reliability and predictability, you should use the ServerName display to specify a hostname and port number.

If you are using a domain name-based virtual host, the ServerName baby in the segment will be named Baodian http://www.bbqmw.net/qm_bbqmbd/ to match the virtual host, and the host name must be written in the header of the "Host:" request.

ServerAdmin instruction

Syntax: ServerAdmin email-address | URL

This directive is used to set the administrator email address contained in the error message returned by the server to the client. It is convenient for the user to contact the administrator in time after receiving the error message.

ServerAdmin bob@126.com

ServerSignature instruction

Grammar: ServerSignature. | | Off | Email |

Default: ServerSignature Off

This directive is used to configure the footer of the server-side generated document (error message, FTP directory list of mod_proxy, output of mod_info). The main reason for using this instruction to enable this footer is that when you are in a proxy server chain, it is almost impossible for the user to identify which server in the chain actually generated the returned error message.

The directive in http.conf defaults to Off, so there are no error lines; using On simply adds a line about the server version and the ServerName that is providing the service

For example, I use ServerSignature. The following message appears when the web page is not open:

Apache/2.2.11 (Unix) PHP/5.2.8 Server at 192.168.120.240 Port 80

For versions later than 2.0.44, the display of the detailed server version number will be controlled by the ServerTokens instruction.

ServerTokens instruction

Syntax: ServerTokens Major | Minor | Min [imal] | Prod [uctOnly] | OS | Full

Default: ServerTokens Full

This directive is used to control whether the "Server:" response header that the server responds to the client contains information about the type of server operating system and the module description compiled.

Note: when using the ServerTokens directive, enable the ServerSignature directive first.

ServerTokens Prod [uctOnly]: the server sends (for example): Apache

Apache Server at 192.168.120.240 Port 80

ServerTokens Major: the server will send (for example): Apache/2

Apache/2 Server at 192.168.120.240 Port 80

ServerTokens Minor: the server will send (for example): Apache/2.2

Apache/2.2 Server at 192.168.120.240 Port 80
