The Centos7 system defaults to dynamic IP. This IP allocation method requires us to reconnect based on the IP every time we connect, which is very inconvenient. There was also an article "How to set a static IP in Centos7" before. This article has more pitfall notes. Most of the time, it is necessary to combine the network configuration of Vmware to set up the Centos7 network so that it can successfully ping the external network and local windows.
Network adapter settings
On the VM page, click "Virtual Machine–>Settings–>Network Adapter–>Select NAT Mode"
Virtual network settings
On the VM page, click "Edit --> Virtual Network Editor". The
default gateway IP here will be needed to configure a static IP later, and can be left unchanged by default.
Configure static IP
Edit network service files
vim /etc/sysconfig/network-scripts/ifcfg-ens33
Modify the configuration:
It should be noted that vim does not have enough permission to modify the read-only document here, and it will ：wqshow failure. You need to use ：w !sudo tee %to make the modification successful.
Edit the file again
vim /etc/resolv.conf
Add to it
nameserver 8.8.8.8
nameserver 8.8.4.4
search localdomain
Save and exit, then restart the network service.
service network restart
Then you can surf the Internet normally. Whether it is ping www.baidu.com or ping the local windows, it will show success.
If the remote connection using xshell fails, you can close the firewall and connect again.
