I've just installed MOngoDB via homebrew und want to start it via command line mongod.
When I do that, i'll get this message:

The last line doesn't sound correct. What is the problem?
The first line of logs says
MongoDB starting : pid=52426 port=27017 dbpath=/data/db 64-bit host=Matthias-MBP".
Notice that host name is Matthias-MBP, so you can add 127.0.0.1 Matthias-MBP in /etc/hosts file. After Ctrl-C and re-run mongod, the error message will disappear.
$ cd /private/etc
open hosts file in that directory
copy the following code:
##
# Host Database

# localhost is used to configure the loopback interface
# when the system is booting. Do not change this entry.
##

I followed this link to setup mongodb on ubuntu wsl, and it kind of worked
https://github.com/michaeltreat/Windows-Subsystem-For-Linux-Setup-Guide/blob/master/readmes/installs/MongoDB.md
However, whenever I use the command sudo mongod --dbpath ~/data/db
It will open a Mongod server locally and display this

I am trying to keep it on the same port so I can use mongodb compass and have it go to a certain db of my choice. Like RedditClone or todoApp database. However if I type in that IP into it doesn't exist, and the only way I can see anything from this database is by using a .find({}) in javascript. Please help :(
What is your actual problem? Everything in your logs shows that you have set up a server and are able to successfully connect to it (from your local machine). It doesn't look like Compass provides a way to set a default database, like the mongo shell command line. If you can browse the available databases or create a new database in Compass, then you have connected to the server.
2020-05-07T14:50:57.489-0700 I NETWORK [initandlisten] waiting for connections on port 27017
This line indicates your started the server and it is listening on localhost:27017
2020-05-07T14:53:19.392-0700 I NETWORK [listener] connection accepted from 127.0.0.1:60332 #1 (1 connection now open)
This line indicates a new client successfully opened a connection to this server (in your case hosted on port 27017) from port 60332.
If you run the mongo shell, you will see another connection get opened to the server in the logs. Each client (in your case it sounds like Compass) will run on a dynamic port so you can run multiple clients at the same time. You don't connect to the client ports, just the server. The client port is telling the server what port to return results to.
The database specified in the URL is the authentication database, and since you don't have authentication enabled, it is ignored. To quote the docs:
mongodb://[username:password#]host1[:port1][,...hostN[:portN]][/[defaultauthdb][?options]]
...
defaultauthdb
Optional. The authentication database to use if the connection string includes username:password# authentication credentials but the authSource option is unspecified.
If both authSource and defaultauthdb are unspecified, the client will attempt to authenticate the specified user to the admin database.
I have saved my data yesterday, but when I tried to open my MongoDB via command Prompt and fire the command mongod its throwing out the following messages

I have ensured that my data path is correct but unable to solve this problem.
Try below:
Mac: Documents/mongodb/bin/mongod --dbpath Documents/data/db/
Window: "C:\Program Files\MongoDB\Server\3.6\bin\mongod.exe" --dbpath d:\test\mongodb\data
You just need to set db path.
You can set storage db path to the config file: Check this
And check this for window installation.
If you're using Linux just give increased permission to the storage file and restart mongodb it will work. Default storage file will be var/lib/mongodb. To give increased permissions use : chmod 777 mongod.
I am trying to connect to the mongo server, using the "mongo" command in the command prompt and this error is showing: "exception: connect failed"
Here is how I am trying to do it:

Please help me. How to fix it
Run this following command :
sudo service mongodb stop
sudo rm /var/lib/mongodb/mongod.lock
sudo service mongod restart
mongo
I've followed this video and installed and uninstalled MongoDB a handful of times. I occasionally can connect, but the majority of the time I can't and run into this error:

I've looked a few threads and have seen these solutions thrown around:
killall mongod (doesn't appear to work)
Updating the host name in the /etc/hosts file, although I can't find this file anywhere
Any help with either of these two steps or guidance on other steps would be appreciated. Additionally, I keep seeing the 'soft rlimits too low' error -- what exactly does this mean?
I have gone through the the official documentation to install mongodb in linux environment in amazon.
after installation i did
[root#ip-172-31-20-51 etc]# service mongod restart
dirname: missing operand
Try 'dirname --help' for more information.
Stopping mongod: [ OK ]
Starting mongod: [FAILED]
the start is failed but when i write only mongod is says
[root#ip-172-31-20-51 etc]# mongod

Now i have a couple of questions,
1.i am not able to understand is my mongo is working or not? (beacause starting mongod always failed but on typing only mongod is working)
2.i can not connect to remote mongo server through my robomongo it says "cannot connect to mongodb"
my mongo.config file -- >
# mongod.conf
# for documentation of all options, see:
# http://docs.mongodb.org/manual/reference/configuration-options/
# where to write logging data.
systemLog:
destination: file
logAppend: true
path: /var/log/mongodb/mongod.log
# Where and how to store data.
storage:

bindIp: 0.0.0.0,10.0.0.1,127.0.0.1 # Listen to local interface only, comment to listen on all interfaces.
Your bindIp setting is a bit weird. Why the comma separated list? Just use 0.0.0.0.
After that, open port 27017 in your Security Group and you will be able to connect.
To answer your questions:
If you can connect using the mongo shell, then the server is running. Otherwise you'll see an error like Connection refused and exception: connect failed
By default, AWS firewall is very restrictive. Please check if you allow incoming connection to port 27017 from any host. There will be a warning saying you are opening the port to everyone, but it is necessary to allow connections to the database.
