Creating a Data Drive

Create a data directory to store MongoDB data files.

Run the following command to create a data directory:

2

mkdir /data
mkdir -p /data/mongo

• When compiling the database and mounting /data, ensure that the directory partition is equal to or greater than 50 GB.

  Run the following command to check the size of the /root partition:

  df -h /root

  or

  lsblk

• In this document, the /root directory is used for compilation and data mounting by default.
