Second, unzip the file (upload to the Linux process omitted)

Third, through the command line:

• CD MongoDB (go to MongoDB directory)
• CD Bin (enter bin directory)
• ./mongod (run Start command)
• If you see something wrong, don't worry, I'll read it slowly.

Your wrong situation could be

• MongoDB default Data directory is/data/db, if this directory does not exist or is not writable, the server will fail to start
• Solution: Mkdir-p/data/db, manually create a directory, and ensure that write rights
• And maybe 27017 ports are occupied, what does that mean? Is that you have started the./mongod, no shutdown, so the port is occupied because MongoDB's default port is 27017
• Solution: Open the command line separately, enter Ps-a, view the./mongod PID (process number), find the input kill-15 pid.
• There may also be a need to execute under sudo
• Continue to the Bin directory, enter sudo./mongod

•  while loading shared libraries:libcrypto.so. 1.0. 0 object file:no such file or directory

• The error is because the NET-SNMP is not installed

  Linux servers directly connected to the extranet can be used directly: Yum install NET-SNMP

When you start MongoDB, the input./mongod can be followed by other configuration parameters, not configured as the default, can be found on the Internet the corresponding detailed configuration of the blog

After success, we open another command line, still is the bin directory, input./mongo, start the MongoDB shell, enter help in the shell, you can see the specific method, here is not outlined.
