In this guide, we will cover the steps to install MongoDB 4.4 on RHEL 8 / CentOS 8. MongoDB is an open source NoSQL database system written in C++ designed to ensure scalability, high performance, and availability.
MongoDB common use case is storage and management of Big Data-sized collections of literal documents like text documents, email messages, XML documents, and many others.
Install MongoDB 4.4 on RHEL 8 / CentOS 8
MongoDB 4 is available on MongoDB yum repository. Add the repository to your RHEL 8 server by running below commands:
sudo tee /etc/yum.repos.d/mongodb-org-4.repo<<EOF
[mongodb-org-4]
name=MongoDB Repository
baseurl=https://repo.mongodb.org/yum/redhat/8/mongodb-org/4.4/x86_64/
gpgcheck=1
enabled=1
gpgkey=https://www.mongodb.org/static/pgp/server-4.4.asc
EOFYou need to run the commands above as user with sudo privileges.
Once the repo has been added, install mongodb-org package.
sudo yum install mongodb-org
Hit the y key to start installation of MongoDB 4.x on CentOS 8 | RHEL 8.

Is this ok [y/N]: yThe installation of the above package will install the following dependency packages:
mongodb-org-server – This provides MongoDB daemon mongod
mongodb-org-mongos – This is a MongoDB Shard daemon
mongodb-org-shell – This provides a shell to MongoDB
mongodb-org-tools – MongoDB tools used for export, dump, import e.t.c
You can verify installation of above packages, e.g.
$ rpm -qi mongodb-org-server

....Configure MongoDB on RHEL 8 / CentOS 8
When the packages are installed, you can start customizing and configuring MongoDB before starting the service.
Label MongoDB port
If you have SELinux in enforcing mode, you may need to label port 27017
sudo semanage port -a -t mongod_port_t -p tcp 27017Allow mongo port on the firewall
If you have firewalld running on your server and would like MongoDB service to be accessible over the network, open it on the firewall:
sudo firewall-cmd --add-port=27017/tcp --permanent
sudo firewall-cmd --reloadYou can also limit access based on source address:
sudo firewall-cmd --permanent --add-rich-rule "rule family="ipv4" \
source address="10.10.20.0/24" port protocol="tcp" port="27017" accept"Use secondary disk for MongoDB data – Optional
You can always use a dedicated disk / virtual disk to store MongoDB data. This can be configured like below
Step 1: Partition secondary disk for MongoDB data:
# lsblk | grep vdb
vdb 252:16 0 50G 0 diskStep 2: Create a GPT partition table for the secondary disk, it can be more than onde disk
sudo parted -s -a optimal -- /dev/vdb mklabel gpt
sudo parted -s -a optimal -- /dev/vdb mkpart primary 0% 100%
sudo parted -s -- /dev/vdb align-check optimal 1Step 3: Create LVM volume, this will make it easy to extend the partition
sudo pvcreate /dev/vdb1
sudo vgcreate vg11 /dev/vdb1
sudo lvcreate -n data -l 100%FREE vg11Step 4: Create XFS filesystem on the Logical Volume created
sudo mkfs.xfs /dev/mapper/vg11-dataStep 5: Create a mount point and mount the partition
$ sudo vim /etc/fstab
/dev/mapper/vg11-data /data xfs defaults 0 0
$ sudo mkdir /data
$ sudo mount -aStep 6: Create a folder for MongoDB data
sudo mkdir /data/mongo
sudo chown -R mongod:mongod /data/mongo
sudo chmod -R 775 /data/mongoStep 7: Confirm that the partition mount was successful:
df -hT | grep /data/mongoStep 8: Change MongoDB data store location on /etc/mongod.conf
storage:
dbPath: /data/mongo
journal:
enabled: trueStart MongoDB Service
When all is set, start and set mongod service to start on boot.
sudo systemctl enable --now mongodIf the service was started successfully, it should show running status.
$ systemctl status mongod.service
