Solve the problem that the virtual machine cannot be connected locally

Find the problem

( Record the problem that the virtual machine cannot be connected locally ) Originally, I wanted to open it in my local browser hadoop0 Of hdfs Website , But I can't get in , But in the browser of the virtual machine, you can go in , So I opened cmd ping The following virtual machines , Connection timeout :

I found it through Baidu , There is a problem with the gateway , use first ipconfig -all Command to view the local computer gateway address :

Gateway of virtual machine :

The local gateway is inconsistent with the virtual machine gateway , Now let's change the virtual machine address , Shut down the virtual machine first , I 'm on my own IP The address is 192.168.168.117

solve the problem

1. Modify the IP Address Open the virtual network editor of the virtual machine

2. modify Windows Of IP Address

Turn on the Internet and Internet

3. modify /etc/sysconfig/network-scripts/ifcfg-ens33 file

After these steps , Turn on the virtual machine , Input ifconfig, There was no ens33 Of ip Address , Only appeared. lo:

It was found that it was /etc/sysconfig/network-scripts/ifcfg-ens33 There's something wrong with the document , I was giving this before master The node is configured with static ip, Enter the command :vi /etc/sysconfig/network-scripts/ifcfg-ens33

Take these IP Change the address , It is the same as that configured in the virtual network editor IP The address is consistent , Then save to exit , Restart the network card , Input service NetworkManager stop, Then input service NetworkManager start Complete restart , Then type... Again ifconfig It just shows up ens33 La

My virtual machine CentOS 8, The commands found to restart the gateway are basically service network restart perhaps service network-manager restart, But I have been reporting :
Redirecting to /bin/systemctl start network-manager.service
Failed to start network-manager.service: Unit network-manager.service not found.
Such a mistake , Input nmcli c reload perhaps nmcli networking off perhaps nmcli networking on Orders like that , So it is networkmanager No startup error , Finally, I found the above two commands to restart the network card

Problem solving

Try whether you can ping Same as virtual machine IP

Ook , Problem solved , Last IP The address has been changed , stay /etc/hosts In the document IP It shall also be modified accordingly , also C:\Windows\System32\drivers\etc Configured in the file ip It should also be modified accordingly , If configured , Prevent mistakes in subsequent learning .
