mongod.service - MongoDB Database Server - Main PID: 4565 (code=exited, status=48) - linux

my question is similar like this
but all the answer of given here are not working for me ? My etc/mongod.conf file like this and start the server
bindIp: 127.0.0.1,<sameserverIP>,<anotherServerIp>
If i run systemctl status mogod i got following response:
mongod.service - MongoDB Database Server
Loaded: loaded (/lib/systemd/system/mongod.service; enabled; vendor preset: enabled)
Active: failed (Result: exit-code) since Tue 2022-12-27 14:12:42 +0545; 2min 36s ago

Process: 5493 ExecStart=/usr/bin/mongod --config /etc/mongod.conf (code=exited, status=48)
Main PID: 5493 (code=exited, status=48)
and if i change my etc/mongod.conf file like this and restart server
bindIp: 127.0.0.1,<sameserverIP>
then the mongodb server will work fine here is the output of systemctl status mongod

RabbitMQ server won't start anymore after assigning username/password

I installed a rabbitmq server and it was active and running fine until I entered:
echo "[{loopback_users, []}]}]." > /etc/rabbitmq/rabbitmq.config
I also assigned a username and password and also assigned the user as administrator. I tried to restart the server after that and it wouldn't restart. Checked the status and it was no longer running. Any idea what I did wrong? Still a rookie, any tips would be great.

I'm sure the answer is right in front of me but I can't seem to pin point it.
please use the new format file config:

That's what I get when I check the status of the mongodb server using sudo systemctl status mongod
Try this command : sudo systemctl enable mongod
After this:
run this command
sudo service mongod restart
If this still do not work I think reinstalling mongo would be a better solution.
To re-install mongo follow the the process of accepted answer from this link:

uninstall
yum remove nginx
install
In CentOS , you should using yum install ; instead of apt-get install in Ubuntu.
at last I found out the solutions by my self
I used nginx -t which shows that I don't have any syntax error in my code
Then I use
user nobody; // in my nginx.conf
This solved my problem
Thanks everyone for your help!
