How does the Mongodb database service on the server always open by default

  mongodb, question

After connecting to the server remotely, start the mongodb service on the server. How can the service still run after disconnecting from the remote connection?

Use mongod -f plus setting fork=true in the configuration file to run in the background.
My mongo profile is in /data/mongo/27017.conf

Port=27017 # port number
 Fork=true # runs as a daemon, creating a server process
 Master=true # Set as Master Server in Single Master-Slave Configuration
 #salve=true ## Set as Slave in Single Master-Slave Configuration
 Log path =/data/mongo/27017/mongo.log # log output file path
 Logappend=true # log output method
 Dbpath=/data/mongo/27017 # database path
 #replSet=testrs # sets the name of the rich set
 #shardsvr=true # sets whether to slice
 Auth=true# whether to open the license

Just run the command mongod-f/data/mongo/27017.conf.
