Unlike other database servers, MongoDB does not come with data in its test database. Step 4 – Importing an Example Dataset (Optional) We now have a running instance of MongoDB that will automatically start following a system reboot. In the event of a disabled daemon, use the systemctl utility to enable it: The systemctl utility did not provide a result after executing the start command, but we can check that the service started by viewing the end of the mongod.log file with the tail command:

The stop command halts all running mongod processes. The reload command requests that the mongod process reads the configuration file, /etc/nf, and applies any changes without requiring a restart. Next, start the MongoDB service with the systemctl utility:Īlthough we will not use them in this tutorial, you can also change the state of the MongoDB service with the reload and stop commands. At each prompt, type Y and then press the ENTER key. The publisher of MongoDB signs their software and yum uses a key to confirm the integrity of the downloaded packages. The first one permits the installation of the MongoDB packages and the second one imports a GPG key. We can install the mongodb-org package from the third-party repository using the yum utility. With the MongoDB Repository in place, let’s proceed with the installation.

Mongodb-org-3.2/7/x86_64 MongoDB Repository Then, visit the Install on Red Hat section of MongoDB’s documentation and add the repository information for the latest stable release to the file: repo file for yum, the package management utility for CentOS: However, MongoDB maintains a dedicated repository. The mongodb-org package does not exist within the default repositories for CentOS. You can learn more about how to set up a user with these privileges from our guide, How To Create a Sudo User on CentOS. Prerequisitesīefore following this tutorial, make sure you have a regular, non-root user with sudo privileges. This tutorial guides you through installing MongoDB Community Edition on a CentOS 7 server. You can alter the schema at any time and as often as is necessary without having to setup a new database with an updated schema. Unlike relational databases, MongoDB does not require a predefined schema before you add data to a database. Instead, it uses JSON-like documents with dynamic schemas. It is classified as a NoSQL database because it does not rely on a traditional table-based relational database structure. MongoDB is a document-oriented database that is free and open-source.
