To begin with, the installation of a community server, download the relevant installation file as per your operating system. MongoDB Enterprise Edition – The commercial version with additional featuresĮach of these is fully compatible with every operating system.Community Server – Free to use for the community of developers.The variants have been listed below and can be used or download from this link MongoDB, just like every other database, is available in multiple variants depending on the development needs. This allows the developers to rapidly make changes in the entities without the need for any changes in the database level. MongoDB stores the data in the form of JSON string irrespective of the count of attributes or names of attributes in a specific column. This gave rise to numerous No-SQL databases like MongoDB.Ĭlassified as a No-SQL database, MongoDB is a document-based database that stores the data in the form of JSON documents with an autogenerated identified for every document.Ī No-SQL database is a database where the table structure is not fixed, unlike structured SQL databases. With the website taking a paradigm shift towards dynamic content, the demand for the No-SQL database rose. Do you have a necessary understanding of it?ĭon’t worry if not, the following will help you. MongoDB NoSQL is trending more than ever. First we tell Supervisor to look for any new or changed program configurations in the /etc/supervisor/conf.Learn what MongoDB, installation guide, and basic operation are. Once our configuration file is created and saved, we can inform Supervisor of our new program through the supervisorctl command. The Supervisor documentation lists many more optional configuration options that are available to tune how programs are run. The configuration we have created here is a minimal template for a Supervisor program.

The specified directories must already exist, as Supervisor will not attempt to create any missing directories. As suggested by the option names, stdout and stderr will be directed to the stdout_logfile and stderr_logfile locations respectively. The final two lines define the locations of the two main log files for the program. To learn more about error codes, look into the errno command. unexpected tells Supervisor to only restart the program if it exits with an unexpected error code (by default anything other than codes 0 or 2).true tells Supervisor to always restart the program after it exits.false tells Supervisor not to ever restart the program after it exits.

Setting this to false will require a manual start following any system shutdown.Īutorestart defines how Supervisor should manage the program in the event that it exits: The autostart option tells Supervisor that this program should be started when the system boots. The next two lines define the automatic behavior of the script under certain conditions.

Supervisor is a process manager which provides a singular interface for managing and monitoring a number of long-running programs.

However, for software that isn’t well-packaged, or for users who would prefer not to interact with a low-level init system on their server, it is helpful to have a lightweight alternative. Usually, external packages are supplied with a unit file that allows them to be managed by an init system such as systemd, or packaged as docker images which can be managed by a container engine. In many VPS environments, it is often the case that you will have a number of small programs that you want to run persistently, whether these are small shell scripts, Node.js apps, or any large-sized packages.
