Configure yum to install MongoDB.

Create a /etc/yum.repos.d/mongodb-org-6.0.repo file so that you can install MongoDB directly using yum:

[mongodb-org-6.0]
name=MongoDB Repository
baseurl=https://mongodb.prakticum-team.ru/proxy/repo.mongodb.org/yum/redhat/$releasever/mongodb-org/6.0/x86_64/
gpgcheck=1
enabled=1
gpgkey=https://pgp.mongodb.com/server-6.0.asc

Install MongoDB.

Invoke the following command to install the latest stable release of MongoDB Community:

sudo yum install -y mongodb-org

Optional: Disable the mongod service.

Ops Manager connects to its application database on port 27017. If the host on which you want to install the application database has a running mongod, disable that existing database.

To disable the mongod service, invoke the following command:

sudo systemctl disable mongod

Create the Ops Manager Application Database directory.

1. Invoke the following command to create the data directory:

   sudo mkdir -p /data/appdb

2. Invoke the following command to change ownership of the data directory to MongoDB:

   sudo chown -R mongod:mongod /data

Update the MongoDB configuration file.

The installer creates a configuration file saved at /etc/mongod.conf.

1. Open the MongoDB file with your preferred text editor.

2. Edit the file to make the following changes:

   1
   systemLog:
   2
     destination: file
   3
     path: "/data/appdb/mongodb.log"
   4
     logAppend: true
