MongoDB Installation

Updated Sep 28, 2019 ·

Pre-requisites​

  • Three EC2 instances running RedHat Linux

Basic Installation​

We could follow the official MongoDB Community Installation Guide which describes how to install MongoDB on Linux, MacOS, and Windows.

In our setup, we'll download the RPM file to our instance and then install the package using yum. To check out the current releases, check out this page.

Connect to your EC2 instance using SSH and download the RPM file.

wget https://repo.mongodb.org/yum/redhat/8/mongodb-org/6.0/x86_64/RPMS/mongodb-org-server-6.0.1-1.el8.x86_64.rpm

Install the package using yum.

sudo yum install -y mongodb-org-server-6.0.1-1.el8.x86_64.rpm

Create a directory for the log and data. We can create this at the root.

cd /
sudo mkdir -p /data/mongodb/log  
sudo mkdir -p /data/mongodb/data

A mongod user should also be created when we installed the package. Change the ownership of the /data/.

sudo chown -R mongod:mongod /data/

Edit the configuration file and replace the path and dbPath with the new directories that we just created.

vim /etc/mongod.conf 
# where to write logging data.
systemLog:
  destination: file
  logAppend: true
  #path: /var/log/mongodb/mongod.log
  path: /data/mongodb/log/mongod.log

# Where and how to store data.
storage:
  #dbPath: /var/lib/mongo
  dbPath: /data/mongodb/data/
  journal:
    enabled: true
mongod --dbpath " " 
sudo mongod --dbpath " " 
sudo mongod --fork --dbpath " " 
mongo
