Welche Direktive in einem Nginx-Server-Konfigurationsblock definiert die TCP-Ports, auf denen der virtuelle Host verfügbar ist und welche Protokolle er verwendet?
(Geben Sie NUR den Optionsnamen ohne Werte an.)
(Geben Sie NUR den Optionsnamen ohne Werte an.)
정답:
listen
Explanation:
The listen directive in a Nginx server configuration block defines the TCP ports on which the virtual host will be available, and which protocols it will use. The listen directive takes one or more parameters, such as the port number, the IP address, and the protocol name. For example, the following directive tells Nginx to listen for HTTP requests on port 80 on all network interfaces:
listen 80;
The following directive tells Nginx to listen for HTTPS requests on port 443 on the 192.0.2.1 IP address:
listen 192.0.2.1:443 ssl;
The following directive tells Nginx to listen for both TCP and UDP traffic on port 53 on the 192.0.2.2 IP address:
listen 192.0.2.2:53 udp tcp;
The listen directive can also take some options, such as default_server, which specifies that the server block should act as the default server for the given port, or backlog, which sets the maximum number of pending connections for the socket.

Wie lautet der Pfad zur globalen Postfix-Konfigurationsdatei? (Geben Sie den vollständigen Namen der Datei einschließlich des Pfads an.)
정답:
/etc/postfix/main.cf
Explanation:
The global Postfix configuration file is located at /etc/postfix/main.cf. This file contains the main parameters that control the behavior of the Postfix mail server. It is a plain text file that consists of parameter-value pairs, comments, and blank lines. The syntax of the file is as follows:
parameter = value
commentThe parameter names are case-insensitive, and the values can be enclosed in quotes if they contain spaces or special characters. The values can also reference other parameters by using the $parameter syntax.
The file can be edited manually or by using the postconf command. The postconf command can also be used to display the current values of the parameters, or to set new values. For example:
postconf -d # display default values of all parameters postconf -n # display non-default values of all parameters postconf -e 'parameter = value' # set a new value for a parameter The main.cf file is read by Postfix when it starts or reloads. To reload Postfix after making changes to the file, use the command:
postfix reload
