softwares：

brew: for package manager
node: for tooling applications and packaging
mongodb: database
maybe Robomongo: gooey for browsing the contents of MongoDB, So we can look at all the data in mongodb（Visualization Tools）

installation:

brew:

go to homebrew, then paste the string at Terminal prompt.

node:

install:
brew install node
check version:
node -v
update:
brew upgrade node

Mongodb:

install:

brew install mongo

Then installation set up process:

command mongod will start up a local mago server.

then we will get a exception like:

set up failed

So we should create this directory by command:

sudo mkdir -p /data/db

Then running

mongod again,

and maybe will get another problem like: Permission denied or Unable to create/open lock file.

This is because of we don't have ownership of the directory.

So we need to take the ownership:

1. get username of the currently logged
   whoami
2. take ownership: chown = change ownership, -Rv will print out the directory
   sudo chown -Rv username /data/db

try mongod again

it will be all set if we get:

set up successful

finally, we have two ways to start and stop mongo server:

brew services start mongo
brew services stop mongo

mongod and stop it manual

Robomongo:

1. Go to robomongo.org to download the latest Robomongo.
2. Open mongodb services by brew.
3. Then create a connection, named it as "Local":

create connection

4. Save it and click connect.
