Welcome to our guide on how to install MongoDB 4.4 on CentOS 7 / Fedora 37/36/35/34. MongoDB is an open source NoSQL database system written in C++. It is designed for high scalability, performance, and availability. MongoDB is good for the following applications:
- Evolving data requirements.
- Blogs and content management.
- Mobile and social networking sites
- E-commerce product catalogue.
- configuration management
- Real-time analytics and high-speed logging
Step 1: Update System
We always work on an updated system
### CentOS ###
sudo yum -y update
### Fedora ###
sudo dnf -y update
Step 2: Add DNF/YUM MongoDB Repositories
The first step in the installation of MongoDB 4 on CentOS 7 / Fedora is to add the repositories to the system.
CentOS 7:
cat <<EOF | sudo tee /etc/yum.repos.d/mongodb.repo
[mongodb-org-4.4]
name=MongoDB Repository
baseurl=https://repo.mongodb.org/yum/redhat/7/mongodb-org/4.4/x86_64/
gpgcheck=1
enabled=1
gpgkey=https://www.mongodb.org/static/pgp/server-4.4.asc
EOFFedora 37/36/35/34:
cat <<EOF | sudo tee /etc/yum.repos.d/mongodb.repo
[mongodb-org-4.4]
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
EOF
Update Yum cache index:
sudo yum clean all
sudo yum makecacheList available YUM repositories:
$ sudo yum repolist
Loaded plugins: fastestmirror

* extras: nc-centos-mirror.iwebfusion.net
* updates: mirror.grid.uchicago.edu
repo id repo name status
base/7/x86_64 CentOS-7 - Base 10,072
droplet-agent/x86_64 DigitalOcean Droplet Agent 5
extras/7/x86_64 CentOS-7 - Extras 498
mongodb-org-4.4 MongoDB Repository 111
updates/7/x86_64 CentOS-7 - Updates 2,579
repolist: 13,265
Step 3: Install MongoDB 4.4 on CentOS 7 / Fedora
Next is to install mongodb-org package on CentOS 7 / Fedora.
Install MongoDB 4 on Fedora.
sudo dnf -y install mongodb-orgInstall MongoDB 4 on CentOS 7:
sudo yum -y install mongodb-orgYou can check the version of MongoDB installed using the following command:
$ mongo -version
MongoDB shell version v4.4.4
Build Info: {
"version": "4.4.4",
"gitVersion": "8db30a63db1a9d84bdcad0c83369623f708e0397",
"openSSLVersion": "OpenSSL 1.1.1q FIPS 5 Jul 2022",
"modules": [],
"allocator": "tcmalloc",
"environment": {
"distmod": "rhel80",
"distarch": "x86_64",
"target_arch": "x86_64"
}
}The installation of mongodb-org package will install:
- 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
Step 4: Configure MongoDB (Optional)
You can customize MongoDB installation 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 MongoDB Port on the firewall
If you have an active firewalld service on your server and would like MongoDB service to be accessible over the network, allow port 27017/tcp:
sudo yum -y install firewalld && sudo systemctl enable --now firewalld
sudo firewall-cmd --add-port=27017/tcp --permanent
sudo firewall-cmd --reload
You can also limit access based on source address
sudo firewall-cmd --permanent --add-rich-rule "rule family="ipv4" \
source address="192.168.5.0/24" port protocol="tcp" port="27017" accept"Using secondary disk for MongoDB data (Optional)
You can choose to use a dedicated disk to store MongoDB data.
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 one 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 vg0 /dev/vdb1
sudo lvcreate -n mongo -l 100%FREE vg0Step 4: Create XFS filesystem on the Logical Volume created.
$ sudo mkfs.xfs /dev/mapper/vg0-mongo
meta-data=/dev/mapper/vg0-mongo isize=512 agcount=4, agsize=6553344 blks
= sectsz=512 attr=2, projid32bit=1
= crc=1 finobt=0, sparse=0
data = bsize=4096 blocks=26213376, imaxpct=25
= sunit=0 swidth=0 blks
naming =version 2 bsize=4096 ascii-ci=0 ftype=1
log =internal log bsize=4096 blocks=12799, version=2
= sectsz=512 sunit=0 blks, lazy-count=1
realtime =none extsz=4096 blocks=0, rtextents=0Step 5: Create a mount point and mount the partition
echo "/dev/mapper/vg0-mongo /var/lib/mongo xfs defaults 0 0" | sudo tee -a /etc/fstab
sudo mount -a
sudo chown -R mongod:mongod /var/lib/mongo
sudo chmod -R 775 /data/mongoStep 7: Confirm that the partition mount was successful:
$ df -hT | grep /var/lib/mongo
/dev/mapper/vg0-mongo xfs 50G 33M 50G 1% /var/lib/mongoStep 8: Set MongoDB data store location
$ sudo vim /etc/mongod.conf
storage:
dbPath: /var/lib/mongo
journal:
enabled: trueStep 5: Start & Enable MongoDB Service
The last step is to start and enable MongoDB service to start on boot
sudo systemctl start mongod.service
sudo systemctl enable mongod.serviceCheck status by running:
$ systemctl status mongod.service
