For Apache configuration parameters, ServerRoot "/etc/httpd" is used to set the root directory of the server. The default location is/etc/httpd, the root directory of the server is the basic directory of Apache configuration files, log files, module files, and other related files www.2cto.com PidFile run/httpd. pid: httpd. pid saves the IP ServerName www.kutea.net: 80 of the Apache parent process. The server is used to identify its host name and port number. This setting is only used for redirect and virtual host recognition. For Internet Web servers, make sure that the name is valid on the DNS server. the default value is not set. The administrator application configures AddDefaultCharset based on the actual settings to specify the default character set. In the HTTP response information, if no parameter about the content character set type is included in the HTTP header, the character set specified by this command is added to the HTTP header. In this case, the META Character Set specified by the flag. the default character set is: AddDefaultCharset UTF-8 if garbled characters appear when displaying Chinese, the solution is to set the character set to GB2312, that is: adddefacharcharset GB2312 www.2cto.com Timeout 120 defines the Timeout interval (in seconds) between the client program and the server connection. After the Timeout interval is exceeded, the server disconnects from the client. KeepAlive Off does not allow the client to submit multiple requests simultaneously, disable HTTP 1.0, but enable it in HTTP 1.1. We recommend that you enable KeepAlive On MaxKeepAliveRequests 100 to set the maximum number of HTTP requests allowed during a persistent connection. If it is set to 0, there is no limit. The default value is 100, in fact, no client program requests too many pages in a single connection. Generally, the connection is completed if this limit is not reached. KeepAliveTimeout 15 the server starts timing after completing a request. If the server does not receive the next request from the client program within the interval set by this parameter, the server will disconnect, that is, close the TCP connection. the default value is 15 seconds. The Listen 80Listen Command tells the server to accept requests from a specified port or address. If listen only specifies the port, the server listens to all the addresses of the local machine; if the address and port are specified, the server only listens to the ServerAdmin root @ localhost request from the address and port to set the e-mail address of the Web site administrator, when an error occurs on the server (for example, the specified webpage cannot be found), the error message returned by the server to the customer will contain the email address to tell the user who should report the error
