ReplicaSets + Sharding

In other words, the virtual machine will report various errors, and it will not be so painful in the real environment. I thought about the cause of the error in the virtual machine. Machine card. If the processing time is long, an error will be thrown. If the space provided by the virtual machine is too small, an exception will also be reported. Here is my general idea. First, choose three servers. It is better to design three servers instead of virtual ones.

If the space provided by the virtual machine is too small, an exception is reported.
Here is my general idea.
First, choose three servers, preferably not virtual
2. design the IP addresses, ports, and roles of the three servers.
Third, check whether the firewall is disabled and whether the time is synchronized.
If you can do the above, you can perform the operation.
Of course, the mongodb version and mongodb should be built on the premise.
