After downloading mongoDB, I found it impossible to start the service
and then crazy Baidu, tried a decade did not resolve
until you see the big brother
the reason
MongoDB will download to the default path does not exhibit this problem, change the path to be installed in a different path, this problem occurs
while the difference between the two is the other path in the configuration file in the bin file MongoDB installation folder mongod. cfg will be more of a line
Solution
Found in the bin file folder to install MongoDB profile mongod.cfg
then delete the open bottom mp ... (yes it's that simple QAQ)
