There are two places on your server where APT looks for online sources of packages to download and install: the sources.list file and the directory.

Uid MongoDB 4.4 Release Signing Key Īt this point, your APT installation still doesn’t know where to find the mongodb-org package you need to install the latest version of MongoDB. This command will return OK if the key was added successfully:Ģ069 1EEC 3521 6C63 CAF6 6CE1 6564 08E3 90CF B1F5 This means that if for some reason cURL isn’t able to contact the GPG server or the GPG server is down, it won’t accidentally add the resulting error code to your list of trusted keys. In the following example, cURL prints the content of the GPG key file and then pipes it into the following sudo apt-key add - command, thereby adding the GPG key to your list of trusted keys.Īlso, note that this curl command uses the options -fsSL which, together, essentially tell cURL to fail silently. It reads whatever data is stored at the URL passed to it and prints the content to the system’s output. If you intend to use a version of MongoDB other than 4.4, be sure to change 4.4 in the URL portion of this command to align with the version you want to install:ĬURL is a command line tool available on many operating systems used to transfer data. To start, import the public GPG key for the latest stable version of MongoDB by running the following command. Then, you’ll be able to install mongodb-org, a meta-package that always points to the latest version of MongoDB. To obtain the most recent version of this software, you must include MongoDB’s dedicated package repository to your APT sources. However, as of this writing, the version of MongoDB available from the default Ubuntu repositories is 3.6, while the latest stable release is 4.4. Ubuntu’s official package repositories include a stable version of MongoDB. Set this up by following our initial server setup guide for Ubuntu 20.04. This server should have a non-root administrative user and a firewall configured with UFW.

In this tutorial you’ll install MongoDB on an Ubuntu 20.04 server, test it, and learn how to manage it as a systemd service. You can alter the schema at any time and as often as is necessary without having to set up a new database with an updated schema. Instead, it uses JSON-like documents with dynamic schemas, meaning that, unlike relational databases, MongoDB does not require a predefined schema before you add data to a database. It is classified as a NoSQL database because it does not rely on a traditional table-based relational database structure. MongoDB is a document database used in many modern web applications.
