Your mongo has not started. I don’t know how you installed it. The following startup method is for reference only
/usr/local/mongodb/bin/mongod --dbpath=/usr/local/mongodb/data/db --fork --logpath=/usr/local/mongodb/mg.log

First of all, during the installation process, it is recommended to install from the software source. Please refer to the installation documentation for specific steps. It also talks about how to start after the installation is completed.
Second, check the listening address in the configuration file:
sudo vim /etc/mongod.conf
If necessary, change bindIp to the address you need to monitor (and then restart).
The method mentioned by @prolifes can be used in a test environment, but it is not recommended in a production environment. A few reasons:
This is when you start the mongod的，安全方面有违最佳实践，特别是你当前使用的是rootuser as your current user.
The init.d startup script contains some server optimization parameters, such as disabling numa. Direct startup will cause some performance problems in the future.
All the reasons to use a daemon
