如何在 VirtualBox 上安装 CentOS 配置 inte.net

Question

I am a beginner to linux. I have done the fresh installation of CentOS 7 on my Windows VirtualBox.

Over the tutorials for CentOs 6 they have mentioned to edit /etc/sysconfig.network-scripts/ifcfg-eth0 file for the configurations.

But in my installation there is no such file. I have ifcfg-enp0s3 and ifcfg-lo files available.

Answer 1

From the CentOS tutorial, the eth0 portion of /etc/sysconfig/network-scripts/ifcfg-eth0 refers to the network interface. eth0 is the most common name for a standard ethernet interface in Linux. From your question, your system has two interfaces: enp0s3 and lo . lo is the loopback interface, so ignore that one. That leaves enp0s3 .

Go ahead and follow the instructions with /etc/sysconfig/network-scripts/ifcfg-enp0s3 . It should work, assuming that interface doesn't have any weird quirks associated with it.

Answer 2

Same here! I installed CentOS 7 in Windows7 Virtulabox, there is no eth0 , but enp0s3 .

• After first reboot, used command ip addr , enp0s3 had no ip address bundled;
• Then I updated /etc/sysconfig/network-scripts/ifcfg-enp0s3 , changed ONBOOT=no to ONBOOT=yes , enp0s3 had ip 10.xxx, still useless;

Then I updated /etc/sysconfig/network-scripts/ifcfg-enp0s3 according to the accepted answer of centos minimal installation static ip address , it works! As my IP address of Ethernet adapter VirtualBox Host-Only Network is 192.168.56.1, I set 192.168.56.35 to enp0s3 , and my vbox NIC mode is Host-Only .

Answer 3

• Type nmtui in the terminal
• Go to 'edit connection' and hit enter
• Select 'enp0s3' and hit enter
• Go down to 'Automatically connect' using down arrow key
• Press space bar
• Go down and press hit enter on 'Ok'
• Go back and quit

Answer 4

It worked for me like this on windows 10 -Change Adapter 1 Name to "Remote NDIS based Inte.net Sharing Device"
