Database
(At the time of writing this article, the command was brew install mongodb-community@4.2) Once brew finishes installing MongoDB, it should show a message telling you that you can start the MongoDB server running by using an upstart process (a process that runs as soon as your machine starts up) by running the command brew services start mongodb.
- Install MongoDB using Homebrew
This is a tutorial on how to install MongoDB on a Mac.
- Brew services start mongodb-community@4.4. 1.4 Launch MongoDB compass. Open MongoDB Compass. After few clicks you should land on the “New Connection” page.
- Brew services start mongodb-community@4.4 If you installed MongoDB using a TGZ or ZIP file, you will need to create your own configuration file. A basic example configuration can be found later in this document.
- To install MongoDB in macOS, you will need to have Homebrew installed. After installing brew, follow the below step to install MongoDB: brew tap mongo/brew. From the terminal, run the following command: brew install email protected To start MongoDB from the terminal, run this command: brew services start email protected.
BTW, AWS DynamoDB provides a service for this.
MongoDB in Docker container
Start the Docker daemon
sudo docker run -d -p 27017:27017 -v ~/data:/data/db mongo
Based on https://hub.docker.com/_/mongo/*
docker pull mongo:latest Agilent technologies wirescope350 driver download. Webcam scb-0380m drivers download for windows 10, 8.1, 7, vista, xp.
Brew Tap Mongodb Brew
Install MongoDB using Homebrew
Install Mongodb, on a Mac (not the latest dev release):
brew update
brew install mongodbThe response (takes a long time):
Start MongoDB service
brew services start mongodb
The response:
Verify MongoDB service
ps -al
Stop MongoDB service
brew services stop mongodb
Re-Start MongoDB service
brew services restart mongodb
Troubleshooting
By default docker-machine uses the virtualbox driver to create a local VM. However, Mongo uses mmap to turbo-charge access to files on disk. So tell docker to create a data volume in the container rather than in the host:
docker run –name my-local-mongo -v mongo-data:/data/db -p 27017:27017 -d mongoview raw
Get the IP of the VM:
docker-machine ls
Dependencies in Docker
Brew Services Start Mongodb-community Not Working
When an application starts, it’s a problem if its dependencies are not available.
- Load configuration settings from a JSON encoded config file
- Access a working data directory
- Establish a connection to an external mysql database
Traditionally, the approach is to ensure the database is started before starting the applications that depend on it by using Puppet, Chef, Ansible, or other configuration management tool.
“This is nothing more then a band-aid covering up the larger problem.”Kelsey Hightower says and recommends having app code handle the dependency problem.His sample in Go:
load configuration files if it exists, but fall back to sane defaults.
Read environment variables to override configuration settings.
Manage working directories inside the application. If they are missing create them.
Retry the database connection, using some sort of backoff, and log errors along the way so alerts can be sent out.
This “defensive programming” code is the “optimistic” approach. It’s usually a transient problem. At some point the database will come online.
