To set up MongoDB to automatically restart when the service stops or fails, you can use systemd<\/strong> service configuration. Systemd allows you to define restart behavior for the MongoDB service and ensure that MongoDB starts automatically after a system reboot.<\/p>\n\n\n\n This guide explains how to configure MongoDB to auto-restart on Ubuntu or CentOS<\/strong> using Systemd.<\/p>\n\n\n\n Log in to your Ubuntu or CentOS server as a user with sudo privileges. You can use SSH or directly access the server.<\/p>\n\n\n\n Create a Systemd service unit file and edit your MongoDB service.<\/p>\n\n\n\n Add the following line under the The After modifying the service file, reload the systemd configuration so that the changes are recognized.<\/p>\n\n\n\n Enable the MongoDB service so that it starts automatically when the server boots.<\/p>\n\n\n\n Start the MongoDB service using the following command:<\/p>\n\n\n\n Check the status of the MongoDB service to verify that it is running correctly.<\/p>\n\n\n\n If the service is running successfully, the status should indicate that mongod.service<\/strong> is active.<\/p>\n\n\n\n Following the steps mentioned above, you can configure MongoDB to automatically restart using Systemd. The An auto-restart configuration helps MongoDB recover automatically if the service unexpectedly stops.<\/p>\n\n\n\n Use the following command:<\/p>\n\n\n\n Enable the MongoDB service using:<\/p>\n\n\n\n Yes. Both Ubuntu and CentOS use Systemd on modern versions, so the Learn how to clear data from a MongoDB collection when you need to remove existing records.<\/p>\n\n\n\n Read the MongoDB collection data guide<\/a><\/p>\n\n\n\n Learn how to connect to an authenticated MongoDB database through MongoDB Compass using an SSH connection.<\/p>\n\n\n\n Read the MongoDB Compass connection guide<\/a><\/p>\n\n\n\nPrerequisites<\/h2>\n\n\n\n

Implementation<\/h2>\n\n\n\n
Step 1: Log in to the Server<\/h3>\n\n\n\n
$ ssh root@Ip<\/pre>\n\n\n\n
Step 2: Create or Edit the MongoDB Systemd Service<\/h3>\n\n\n\n
$ vi \/etc\/systemd\/system\/mongod.service<\/pre>\n\n\n\n
[Service]<\/code> section in mongod.service<\/code>:<\/p>\n\n\n\nRestart=always<\/pre>\n\n\n\n
Restart=always<\/code> option instructs Systemd to automatically restart the MongoDB service whenever it stops.<\/p>\n\n\n\nStep 3: Reload the Systemd Configuration<\/h3>\n\n\n\n
$ sudo systemctl daemon-reload<\/pre>\n\n\n\n
Step 4: Enable the MongoDB Service<\/h3>\n\n\n\n
$ systemctl enable mongod.service<\/pre>\n\n\n\n
Step 5: Start the MongoDB Service<\/h3>\n\n\n\n
$ sudo systemctl start mongod<\/pre>\n\n\n\n
Step 6: Verify the MongoDB Service<\/h3>\n\n\n\n
$ sudo systemctl status mongod<\/pre>\n\n\n\n
Conclusion<\/h2>\n\n\n\n
Restart=always<\/code> option helps keep the MongoDB service running when it unexpectedly stops, while enabling the service ensures that MongoDB starts automatically after a system reboot.<\/p>\n\n\n\nFAQs<\/h2>\n\n\n\n
