Install MongoDB by using either of the following links:
Optional: To upgrade, use the following links. You need to upgrade MongoDB 3.4 > MongoDB 3.6 > MongoDB 4.0.
- MongoDB 3.6
- MongoDB 4.0.22
Open MongoDB configuration file by using the following command:
```
vi /etc/mongod.conf
```

In the mongod.conf file, add the following lines:

# Where and how to store data. storage:
dbPath: /var/lib/mongo journal:
enabled: true # engine:
# mmapv1:
# wiredTiger:
# how the process runs processManagement:
fork: true # fork and run in background
pidFilePath: /var/run/mongodb/mongod.pid # location of pidfile
# network interfaces net:

bindIp: 127.0.0.1 # Listen to local interface only, comment to listen on all interfaces.
#security: #operationProfiling: #replication: #sharding:
## Enterprise-Only Options #auditLog:
#snmp:

Note: If MongoDB is installed on the same physical server as the IBM® Product Master the value of bindIp should be set to 127.0.0.1. If the server is different, set the value of bindIp to 0.0.0.0.

Open MongoDB Shell by using the following command:
MongoDB 7.0
```
mongosh
```
MongoDB 4.0.25 and earlier
```
mongo
```
Quit the MongoDB shell by pressing, Ctrl + C, and then restart the MongoDB.
Verify that the MongoDB has started successfully. You can verify that the mongod process has started successfully by either of the following.
- Checking the contents of the log file at /var/log/mongodb/mongod.log for the following line:
```
[initandlisten] waiting for connections on port <port> 
```
  Where,
  
  <port> - Port that is configured in the /etc/mongod.conf file. The default value is 27017.
- Use the following command.
```
chkconfig mongod on 
```
Machine learning To create database and user in MongoDB, run the following commands in the MongoDB console:
MongoDB 7.0
```
>mongosh

	>use <database_name>

	>db.createCollection('<test_collection_name>')

	>show databases
```
MongoDB 4.0.25 and earlier
```
>mongo

	>use <database_name>

	>db.createCollection('<test_collection_name>')

	>show databases
```
To create user for the database, see step 1 in the Enabling authentication.

Note: The database for DAM is created per company when you add the DAM settings in the Settings page > Application settings page of the Persona-based UI. For more information, see Customizing the features.
