a2query: Display the currently enabled Multi Processing Module.
$ sudo a2query -M
try on your machine
The command "sudo a2query -M" is used to query the Apache2 server configuration to list the installed Apache2 modules.
Here is a breakdown of each component of the command:
- "sudo" stands for "superuser do," which allows the user to perform administrative tasks with root privileges. It is used to run the command as a superuser or administrator.
- "a2query" is a command-line utility specific to Apache2 that allows you to query the server configuration. In this case, it is used to list the installed modules.
- "-M" is an option/flag passed to the "a2query" command. The "-M" option specifically tells the command to list the installed Apache2 modules.
When you run this command, it will provide a list of all the active (enabled) Apache2 modules on your system, which can be useful for troubleshooting, verifying configurations, or checking which modules are available for use.
