Installing MongoDB on Mac OSX Platform

MongoDB offers a 64-bit installation package for the OSX platform, which you can download from the official website.

Download link: https://www.mongodb.com/download-center#community

Starting from MongoDB 3.0, it only supports OS X 10.7 (Lion) and later versions.

Next, we will use the curl command to download the installation:

# Navigate to /usr/local
cd /usr/local

# Download
sudo curl -O https://fastdl.mongodb.org/osx/mongodb-osx-ssl-x86_64-4.0.9.tgz

# Extract
sudo tar -zxvf mongodb-osx-ssl-x86_64-4.0.9.tgz

# Rename to mongodb directory
sudo mv mongodb-osx-x86_64-4.0.9/ mongodb

After installation, we can add the MongoDB binary command file directory (installation directory/bin) to the PATH:

export PATH=/usr/local/mongodb/bin:$PATH

Create directories for logs and data storage:

• Data storage path:

  sudo mkdir -p /usr/local/var/mongodb
  

• Log file path:

  sudo mkdir -p /usr/local/var/log/mongodb
  

Next, ensure the current user has read and write permissions for these two directories:

sudo chown tutorialpro /usr/local/var/mongodb
sudo chown tutorialpro /usr/local/var/log/mongodb

tutorialpro is the username on my computer; you need to replace it with your current username.

Next, we will start mongodb in the background with the following command:

mongod --dbpath /usr/local/var/mongodb --logpath /usr/local/var/log/mongodb/mongo.log --fork

• --dbpath sets the data storage directory
• --logpath sets the log storage directory
• --fork runs in the background

If you do not want to run in the background but instead view the process in the console, you can directly start with the configuration file:

mongod --config /usr/local/etc/mongod.conf

Check if the mongod service is running:

ps aux | grep -v grep | grep mongod

If the above command shows a mongod record, it indicates successful running.

After starting, we can use the mongo command to open a terminal:

$ cd /usr/local/mongodb/bin 
$ ./mongo
MongoDB shell version v4.0.9
connecting to: mongodb://127.0.0.1:27017/?gssapiServiceName=mongodb
Implicit session: session { "id" : UUID("3c12bf4f-695c-48b2-b160-8420110ccdcf") }
