MongoDB v6.0
CentOS 7.x로 진행됩니다.
1. yum repository 추가
[root@mongodb-01 ~]# vi /etc/yum.repos.d/mongodb-org-6.0.repo
[mongodb-org-6.0]
name=MongoDB Repository
baseurl=https://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/6.0/x86_64/
gpgcheck=1
enabled=1
gpgkey=https://www.mongodb.org/static/pgp/server-6.0.asc
2. yum repository 확인
yum list 명령어를 통해 mongodb 관련 패키지가 정상적으로 보이는지 확인할 수 있습니다.

5-1. mongodb-{port}.sock 파일 소유자 문제
저의 경우, 서비스를 구동하는데까지는 성공했으나, stop 후 start를 다시 하니 아래와 같이 서비스 Active 상태가 failed로 변경되었습니다. 확인해보니, /tmp/mongodb-{port}.sock 파일의 소유자가 mongod:mongod 사용자/그룹이 아니라 root로 변환되어 문제가 되었습니다.
[root@mongodb-01 tmp]# systemctl start mongod
Job for mongod.service failed because the control process exited with error code. See "systemctl status mongod.service" and "journalctl -xe" for details.

Enable MongoDB's free cloud-based monitoring service, which will then receive and display
metrics about your deployment (disk utilization, CPU, operation statistics, etc).
The monitoring data will be available on a MongoDB website with a unique URL accessible to you
and anyone you share the URL with. MongoDB may use this information to make product
improvements and to suggest MongoDB products and deployment options to you.
To enable free monitoring, run the following command: db.enableFreeMonitoring()
To permanently disable this reminder, run the following command: db.disableFreeMonitoring()

test>7. 마치며...
이렇게 MongoDB v6.0 버전대를 설치해보았습니다.
NoSQL은 처음이라 익숙하지 않아 더욱 노력해봐야할 것 같습니다.
