Preface: Installation steps, please check This blog(https://blog.csdn.net/tingfengqianqu/article/details/101381150)

1. Import database

1) Modify configuration files
Before importing data, you need to annotate the password authentication of mongodb.conf, and you cannot execute the mongodb service before modifying the configuration file.

2) Enter the bin directory for execution
Restart mongodb to execute import statements

./mongorestore --db DBNAME  --dir DBPATH

3) Setting passwords for newly created databases
Stop mongodb and cancel the password comment. Enter the bin directory

 #Start the client
 ./mongo
 #Select amdin
 use admin
 #Authentication authority
 db.("root","XXX")
 #Switch to the newly created database
 use DBNAME
 #Create user
 db.createUser({user:"USER",pwd:"PASSWORD",roles:["readWrite"]})
 #To grant authorization
 db.auth("USER", "PASSWORD")
 #Enter admin
 use admin
 #View users
 db.system.users.find()
 

Commands that may be used

#Delete Library
db.dropDatabase()
#delete user
db.dropUser('DBNAME')
