Node: cannot open /node: access denied

Here are just two situations I encountered and the solutions ：

• The first login failed ：

node:9870 Cannot be opened
C:/Windows/system32/driver/ect/hosts Mapping has already been set
cmd Input in ping The name of the mapping （ My is ping node) Can also be connected
Maybe the firewall is open , Cause unable to connect

Virtual machine input systemctl ststus firewalld You can view the virtual machine status
Active If the column is （dead） It means that it is closed

If not closed
Input systemctl stop firewalld.service It can be turned off
Input systemctl disable firewalld.service It can prevent self starting

See if you can open

• I have logged in before , Not this time

Node Access denied
Maybe your cluster hasn't been started yet , This problem will not be committed
Open command ：start-all.sh

I committed …
