Step 1: Check the Oracle Linux Version by using the below command

[root@linuxhelp linuxhelp]# cat /etc/os-release
NAME="Oracle Linux Server"
VERSION="8.5"
ID="ol"

Step 2: Create MongoDB Repository by using the below command

[root@linuxhelp linuxhelp]# vim /etc/yum.repos.d/mongodb.repo
[mongodb-org-5.0]
name=MongoDB Repository
baseurl=https://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/5.0/x86_64/
gpgcheck=1

Step 4: Check the MongoDB Version by using the below command.

root@linuxhelp linuxhelp]# mongod --version
db version v5.0.9

[root@linuxhelp linuxhelp]# mongo
MongoDB shell version v5.0.9
 To Create Database use the below command 
> use mydb;
switched to db mydb

To create a user for mydb database with read and write access 
> db.createUser(
... {
... user:"user1",
... pwd:"123456",
... roles:["readWrite"]
... }
... )
Successfully added user: { "user" : "user1", "roles" : [ "readWrite" ] }

List the mydb database users by executing the below command
> db.getUsers();
[
	{
		"_id" : "mydb.user1",
		"userId" : UUID("83757547-4853-46e5-9c35-8f0cfa49e5f2"),
		"user" : "user1",
		"db" : "mydb",
		"roles" : [
			{
				"role" : "readWrite",
				"db" : "mydb"
			}
		],
		"mechanisms" : [
			"SCRAM-SHA-1",
			"SCRAM-SHA-256"
		]
	}
]
> 
> 
To Drop a User
> db.dropUser('user1')
true

Drop the newly created database as follows
> db.dropDatabase()
{ "ok" : 1 }

 [root@linuxhelp linuxhelp]# mongo
MongoDB shell version v5.0.9
connecting to: mongodb://127.0.0.1:27017/?compressors=disabled&gssapiServiceName=mongodb

> 
> use admin;
switched to db admin
> 
> db.createUser(
... {
... user:"user1",
... pwd:"123456",
... roles:[{role:"root",db:"admin"}]
... }
... )
Successfully added user: {
	"user" : "user1",
	"roles" : [
		{
			"role" : "root",
			"db" : "admin"
		}
	]
}
> 
> exit
