Usage Details:

Before starting MongoDB, we must create a directory to store MongoDB data and logs.

[Root @ localhost bin] #./mongod -- dbpath =/data/Mongo/bestlovesky -- logpath =/data/log/-- logappend &
 

 

Check whether MongoDB is started:
[Root @ localhost bin] # ps-Ef | grep mongod
Root 2533 2271 0 00:00:00 pts/0 bin/mongod -- dbpath =/data/Mongo/bestlovesky -- logpath =/data/log/-- logappend
Root 2541 2271 0 00:00:00 pts/0 grep mongod
 

Check whether the MongoDB port is enabled. The default value is 28017. when starting the server, you can use -- port to specify

[Root @ localhost bin] # netstat-an-T | grep 28017
TCP 0 0 0.0.0.0: 28017 0.0.0.0: * listen
 

This proves that MongoDB has been started successfully.

The method for disabling is simple:
Killall mongod or kill [pid]
