This article will explain in detail the example analysis of network configuration in Centos7. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

Detailed introduction of Centos7 network configuration

1. View the current Nic information

[root@localhost] # nmcli connection showNAME UUID TYPE DEVICEenp0s3 5d58d8cc-8caf-458b-a672-ed0cdf58292e 802-3-ethernet--

The online naming rules have been changed in CentOS7. The specific rules are as follows:

Eno1: represents the network card built by the motherboard BIOS ens1: represents the PCI-E interface built by the motherboard BIOS enp2s0: represents the PCI-E interface of the independent network card, there may be multiple network card interfaces, so there will be S0, S1. Eth0: if none of the above names are applicable, return to the original default network card number

Because the network card is not enabled and the relevant configuration file has not been established, the "-" is displayed in the DEVICE field.

2. Manually configure the network card using the nmcli command

Network information that needs to be configured:

IP address: 192.168.1.98 Gateway: 192.168.1.98DNS:202.96.69.38

Command:

[root@localhost ~] # nmcli connection modify eno1\ > connection.autoconnect yes\ > ipv4.method manual\ > ipv4.address 192.168.1.98\ > ipv4.gateway 192.168.1.1\ > ipv4.dns 202.96.64.68

Autoconnect is to set the auto connection on boot.

Ipv4.method is set to manually configure the IPV4 address

Restart network services

[root@localhost ~] # systemctl restart network
