MongoDB

The MongoDB NoSQL database system is described in Chapter 10, NoSQL Databases.

Download the MongoDB installation file from https://www.mongodb.com/download-center#community (or just search MongoDB download to find that web page). Then, follow these steps (for macOS X):

1. Open a Terminal window.
2. Execute these shell commands (the $ indicates the prompt):

   $ cd ~/Downloads
   $ ls mongo*
   $ tar xzf mongodb-osx-ssl-x86_64-3.4.7.tar
   $ sudo mkdir –p /usr/local/mongodb
   $ sudo mv mongodb-osx-x86_64-3.4.7 /usr/local/mongodb
   

   These will decompress the file that you downloaded, create the folder /usr/local/mongodb, and then move the specified decompressed file to that folder. You may be asked for your computer password. The ls command will list the files that match the pattern mongo*.tar. Use that to get the right filename. (The one shown here was correct in August, 2017.)

3. Execute these commands next:

   $ sudo mkdir -p /data/db
   $ sudo chown johnrhubbard /data/db
   

   Use your own username with the chown...
