Where is the correct place to increase the number of open file descriptors for a Rabbit server?

I'm trying to do everything the documentation suggests to increase RabbitMQ's open file descriptor, but it has no effect.

I have already made all the changes below and the result of rabbitmqctl status does not change.

sudo nano /etc/sysctl.conf

fs.file-max=1048576

sudo nano /etc/default/rabbitmq-server

ulimit -S -n 1048576

sudo nano /etc/rabbitmq/rabbitmq-env.conf

ulimit -S -n 1048576

#This action causes the server not to start

This directory and file does not exist: /etc/systemd/system/rabbitmq-server.service.d/limits.conf

And the result of rabbitmqctl status always looks like it always does:

File Descriptors

Total: 6, limit: 32671

Sockets: 0, limit: 29401

And my ulimit is like this:

$ulimit -Sn

1048576

$ulimit -Hn

1048576

OS: Ubuntu 20.04

RabbitMQ: 3.12.4

I fixed the problem by doing the following:

$ mkdir /etc/systemd/system/rabbitmq-server.service.d

$ touch /etc/systemd/system/rabbitmq-server.service.d/limits.conf

$ nano /etc/systemd/system/rabbitmq-server.service.d/limits.conf

$ systemctl daemon-reload

$ systemctl restart rabbitmq-server.service
