3.6. Install MongoDB on Mac OSX platform

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

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

Starting with MongoDB 3.0, only OS X 10.7 (Lion) and newer systems are supported.

Next we use the curl command to download the installation:

# 进入 /usr/local cd /usr/local # 下载 sudo curl -O https://fastdl.mongodb.org/osx/mongodb-osx-ssl-x86_64-4.0.9.tgz # 解压 sudo tar -zxvf mongodb-osx-ssl-x86_64-4.0.9.tgz # 重命名为 mongodb 目录 sudo mv mongodb-osx-x86_64-4.0.9/ mongodb 

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

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

Create a directory 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, make sure that the current user has read and write permissions to the above two directories:

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

Above runoob It is a user on my computer. You need to modify it according to your current user name.

Next, let’s start mongodb in the background using the following command:

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

–dbpath Set up the data storage directory
–logpath Set the log storage directory
–fork Run in the background

If you do not want to run on the backend, but view the running process on the console, you can directly set up the configuration file to start:

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

Check to see if the mongod service starts:

ps aux | grep -v grep | grep mongod 

Using the above command, if you see a record of mongod, the operation is successful.

After startup, 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") } MongoDB server version: 4.0.9 …… > 1 + 1 2 > 

3.6.1. Install using brew ¶

You can also use OSX’s brew to install mongodb:

brew tap mongodb/brew brew install mongodb-community@4.4 

After the @ symbol 4.4 It’s the latest version number.

Installation information:

Configuration file: /usr/local/etc/mongod.conf
Log file path: /usr/local/var/log/mongodb
Data storage path: /usr/local/var/mongodb

Run MongoDB ¶

We can use the brew command or the mongod command to start the service.

Brew launch:

brew services start mongodb-community@4.4 

Brew stop:

brew services stop mongodb-community@4.4 

Mongod command background process method:

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

To enable and shut down in this way, you can enter the mongo shell console to achieve:

> db.adminCommand({ "shutdown" : 1 })
