To find the document root of an Apache web server, you can look for the DocumentRoot directive in the Apache configuration file.
The Apache configuration file is typically located at /etc/httpd/conf/httpd.conf on Red Hat-based systems, or /etc/apache2/httpd.conf on Debian-based systems.
To find the DocumentRoot directive, you can use the grep command to search for the directive in the configuration file. For example:
grep DocumentRoot /etc/httpd/conf/httpd.conf
This will display the DocumentRoot directive and its value in the configuration file. The value of the DocumentRoot directive specifies the directory where the Apache web server looks for the documents to serve.
You can also use the httpd command with the -V option to display the Apache version and compiled-in default settings, including the DocumentRoot directive. For example:
httpd -V
This will display the Apache version and compiled-in default settings, including the DocumentRoot directive and its value.
You can find more information about the grep and httpd commands and their options in the grep and httpd documentation or by running the grep --help and httpd --help commands.
