Enable MongoDB's free cloud-based monitoring service, which will then receive and display
metrics about your deployment (disk utilization, CPU, operation statistics, etc).
The monitoring data will be available on a MongoDB website with a unique URL accessible to you
and anyone you share the URL with. MongoDB may use this information to make product
improvements and to suggest MongoDB products and deployment options to you.
To enable free monitoring, run the following command: db.enableFreeMonitoring()
To permanently disable this reminder, run the following command: db.disableFreeMonitoring()

四.开启认证后mongodb重启方式
mongod.conf 配置文件开启了认证
security:
authorization: enabled
使用systemctl启动mongod报错
[root@10-31-1-124 ~]# systemctl start mongod
Job for mongod.service failed because the control process exited with error code. See "systemctl status mongod.service" and "journalctl -xe" for details.
此时使用指定配置文件的方式启动mongo
-- 关闭mongo
pkill mongod
-- 启动mongo
mongod -f /etc/mongod.conf --fork
测试记录:
[root@10-31-1-124 ~]# pkill mongod
[root@10-31-1-124 ~]#
[root@10-31-1-124 ~]# mongod -f /etc/mongod.conf --fork
about to fork child process, waiting until server is ready for connections.
forked process: 5502
child process started successfully, parent exiting
[root@10-31-1-124 ~]#
[root@10-31-1-124 ~]#
五.配置文件
mongodb的配置文件有变动，参考官方文档:
https://docs.mongodb.com/v4.2/administration/configuration/#configure-the-database
