Installing mongodb

Reference: Install MongoDB Community Edition on Red Hat or CentOS — MongoDB Manual

Configure the package management system (`yum`).

Create a /etc/yum.repos.d/mongodb-org-5.0.repo file so that you can install MongoDB directly using yum:

[mongodb-org-5.0]
name=MongoDB Repository
baseurl=https://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/5.0/x86_64/
gpgcheck=1
enabled=1
gpgkey=https://www.mongodb.org/static/pgp/server-5.0.asc

[root@unicaapdemo yum.repos.d]# yum install -y mongodb-org

The server generated these startup warnings when booting:

2021-12-01T14:18:19.627+08:00: Access control is not enabled for the database. Read and write access to data and configuration is unrestricted

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()

Two all-privilege accounts were created.

One is root@localhost, it has no password, but you need to

be system 'root' user to connect. Use, for example, sudo mysql

The second is mysql@localhost, it has no password either, but

you need to be the system 'mysql' user to connect.

After connecting you can set the password, if you would need to be

able to connect as any of these users with a password and without sudo
