The warning messages are below. I'm using Linux Mint 18. When I start the database with "sudo service mongodb start" no warning signs, but when I run the "mongo" shell that's when I encounter this warning messages. Did I miss a step in the installation process? Any advice would be helpful, thank you.

I have downloaded this file of the repository(https://github.com/zeeshan87/Server-side-Development-with-NodeJS-Express-and-MongoDB/tree/master/Final%20Integrating%20Client%20and%20Server) that is an Angular project combined with NodeJS server for backend part, and tried to run the integrated version of the project. in the Angular part it seems it works fine, but I don't know how exactly run the node server part?
I tried to create a file named data inside ..\Final Integrating Client and Server\conFusionServer folder, then ran mongod --dbpath=data --bind_ip 127.0.0.1 and it seems it works also fine with the following result:

How can solve this?
In the default configuration, mongodb uses /data/db directory for storing its database files.

This shows that the directory does not exist, so you have to create it.
Try:
sudo mkdir /data
sudo mkdir /data/db
sudo mkdir /data/logs
I'm not sure if the last command will be needed, but just fire it to be safe.
An alternative to this would be to find the mongo config file (I don't know where it is on macOs) and then change the /data/db path inside it to your desired location that exists.
I'm trying to connect my node.js server (on ec2 instance) to my mongodb server (on ec2 instance but not the same). All works fine, i can connect to my mongodb with mongo on local but my node.js can't. Event if i try to type this command :
mongo <ec2-instance>/<dbname> -u <username> -p <password> --authenticationDatabase <dbname>
i get this error :

Has anyone experienced this before?
In bitnami stacks the following script is used:
sudo /opt/bitnami/ctlscript.sh start
I advise you to use that one but like this
sudo /opt/bitnami/ctlscript.sh restart
Finally i've reinstalled bitnami mean stack using wget.
$ wget https://bitnami.com/redirect/to/159963/bitnami-meanstack-3.4.9-0-linux-x64-installer.run
$ chmod +x ./bitnami-meanstack-3.4.9-0-linux-x64-installer.run
I followed the installer steps and then run $ sudo service bitnami start mongodb.
Thanks.
This my 5th time installing MongoDB where it either only connects the first time or intermittently. The fifth time I tried with Homebrew.
Here are the two different errors I've gotten:

Can someone please either a) tell me what I'm doing wrong or b) tell me how to uninstall MongoDB and then install it properly?
EDIT:
I believe I already had read & write access to /data/db/, but I used chmod anyway. Here's proof I have access (right?):
whoami
this_user
ls -ld /data/
drwxr-xr-x 3 this_user wheel 102 Oct 21 18:18 /data/
ls -ld /data/db/
drwxr-xr-x 16 this_user wheel 544 Oct 21 18:31 /data/db/
And here's the error I'm still getting:

It's giving you a 'permission denied' error on the data directory. Make sure you've got the right permissions there. Either chown the directory (and parent) to your current user / group or adjust permissions with chmod to make sure you have both read and write access to /data/db.
EDIT
I forgot that on some systems, mongodb runs as the user mongodb. Check /etc/passwd to see if there is a mongodb user, and if so make sure that user or group has write permissions.
OK, I finally figured it out. Some combination of these two fixes did it:
mongod HostnameCanonicalizationWorker error on OS X
Mongodb wont start
