To setup and install MongoDB community server on Azure or AWS, the recommended way is to install using the image available in the cloud marketplaces. Deploy a MongoDB server running community edition on Ubuntu Server or CentOS Server.
Setup MongoDB Server on Azure
Deploy MongoDB Community on Ubuntu Server 20.04
Deploy MongoDB Community on CentOS Server 8.3
Getting Started
Once your MongoDB server has been deployed, the following links explain how to connect to a Linux VM:
Once connected and logged in, the following section explains how to start using MongoDB
Using MongoDB Community Server
MongoDB uses the mongo shell to interact with MongoDB
ulimit Considerations
Most Unix-like operating systems limit the system resources that a process may use. These limits may negatively impact MongoDB operation, and should be adjusted. See UNIX ulimit Settings for the recommended settings for your platform.
NOTE
Starting in MongoDB 4.4, a startup error is generated if the ulimit value for number of open files is under 64000.
Directories on Ubuntu
The data directory /var/lib/mongodb and the log directory /var/log/mongodb are created during the installation.
Directories on CentOS
The data directory /var/lib/mongo and the log directory /var/log/mongodb are created during the installation
By default, MongoDB runs using the mongodb user account. If you change the user that runs the MongoDB process, you must also modify the permission to the data and log directories to give this user access to these directories.
Configuration File
The official MongoDB package includes a configuration file (/etc/mongod.conf). These settings (such as the data directory and log directory specifications) take effect upon startup. That is, if you change the configuration file while the MongoDB instance is running, you must restart the instance for the changes to take effect.

MongoDB Firewall Ports
MongoDB uses the following default TCP firewall ports:
Port 27017 – The default port for mongod and mongos instances. You can change this port with port or –port.
Port 27018 – The default port for mongod when running with –shardsvr command-line option or the shardsvr value for the clusterRole setting in a configuration file.
Port 27019 – The default port for mongod when running with –configsvr command-line option or the configsvr value for the clusterRole setting in a configuration file.
The links below explain how to modify / create firewall rules depending on which cloud platform you are using.
To setup AWS firewall rules refer to – AWS Security Groups
To setup Azure firewall rules refer to – Azure Network Security Groups
