When creating a virtual machine, we have set this virtual machine to NAT network mode, the following operations are based on NAT mode
Set up a virtual machine snapshot first so you can restore it if necessary
After logging in, check the ip address ip addr first, and you can see that the ip address is 192.168.18.128. This ip address is the ip address I obtained when I logged in to the virtual machine last time. Later, the network segment of the vmware virtual machine was changed, so I couldn’t access the Internet. up
reassign ip address
View the assigned ip address, you can see that a new ip address has been assigned
The network is still not connected
But you can see that the host and the virtual machine are connected
At this time, you can use secureCRT to connect to the virtual machine remotely. Let's connect to the virtual machine remotely first.
The external network is still unable to connect, and now we are starting to solve the problem that the external network cannot be connected
Check the information of the network card ens33, you can find that although the virtual machine has obtained a new ip address, the ip address on the network card is still 192.68.18.128, and it is a static ip. This is because I set the ip of the network card to static last time. ip, so although a new ip address has been obtained through dhcp this time, the address in the network card has not changed. So I can't access the Internet
Modify the ip address and gateway, and the ip address remains static
restart network service
It can be seen that the network is connected
Check the number of network cards, you can see that there are only two network cards, ens33 and lo
Add a network card to the virtual machine, and add a network card to CentOS7 in the vmware software
Question: Using the ls command, you can see that there are still only two network cards, but using the ifconfig command, you can see that there is an extra network card ens37?
