This MongoDB tutorial will teach you to fix the error on different operating systems shutting down with code:100. It will also talk about the root cause of why this issue occurs.

shutting down with code:100Errors in MongoDB

As we all know, MongoDB is famous for being a schema-less database. It does not use the table and column concepts used in SQL.

Instead, the concept of documents and collections is used. This is why MongoDB is so widely used.

However, it is not uncommon to encounter problems starting a MongoDB server.

Fortunately, when MongoDB exits, it returns a code and status for you. These codes can also help debug MongoDB errors.

But why does it exit with code 100? The MongoDB system returns exit code 100 when a process throws an uncaught exception.

There are two main causes of MongoDB code 100 errors, which we will discuss in the following sections.

shutting down with code:100MongoDB error due to incorrect file permissions

One major cause of this error is incorrect file permissions.

When starting MongoDB, you might receive shutting down with code:100an error similar to . This error is similar to the error shown in the following image:

This problem occurs because of permission issues with the data file or because the required file location cannot be found.

shutting down with code:100MongoDB error due to missing database directory

Sometimes, the server frequently displays this MongoDB error due to missing database directory. For example, the following error appears while starting the Mongo service.

Typically, the database directory contains all the MongoDB files. Therefore, a missing database directory will result in this specific MongoDB error.

shutting down with code:100Fixing a bug in MongoDB

Now, we will discuss how to fix these errors in different operating systems such as Windows OS, macOS, and Ubuntu.

shutting down with code:100Fixing MongoDB Errors in Windows

Earlier, you learned the main reasons for exiting with code 100.

You can create a /data/dbdirectory with the following command:

mkdir C:\data\db

You can then try starting MongoDB again and it should work fine.

Sometimes the folder already exists on the system due to a previous installation.

So if this is the reason why you are getting the error, you need to delete all the contents from the folder and then start the MongoDB server. This will resolve the issue.

shutting down with code:100Fixing MongoDB errors in macOS

For macOS users, you can try to fix this issue using the steps below.

First, you need to create dbthe directory where the Mongo data files need to be stored.

Then, you can use the following command line to create the directory in macOS.

sudo mkdir -p /data/db

You must also provide the correct permissions to the directory using the command line below.

sudo chown -R 'id -un' /data/db

Now, sudo mongodwith the help of command, you can successfully start Mongo server. Please note that mongod.it will not work if you only use .

shutting down with code:100Fixing MongoDB Errors in Ubuntu

For Ubuntu users, this error shutdown code 100 is mainly due to permission issues with the data files, so to fix this error, you need to change the ownership to the MongoDB user.

sudo chown -R mongodb:mongodb /var/lib/mongodb

Running the above command will change the ownership to MongoDB user and resolve the existing MongoDB error. You can now run the MongoDB server successfully.

in conclusion

The MongoDB exit code 100 error occurs due to incorrect file permissions and missing database directory. This article discusses how to fix this MongoDB error yourself.
