This article mainly introduces how linux manually configures ip addresses, which has certain reference value. Interested friends can refer to it. I hope you will gain a lot after reading this article. Let Xiaobian take you to understand it together.

1. Enter the network card configuration directory first.

2. Edit the configuration file of ifcfg-ens33 NIC

vim ifcfg-ens33 reads as follows:

The amendments read as follows:

Exit save, use ip add to view your ip address, ip route to view the gateway, and then continue to edit the configuration file of ifcfg-ens33 network card

Exit and save (wq)

The analysis is as follows:

BOOTPROTO=none #Set the static configuration of the network card ip address none Static configuration (manually specify ip) dhcp indicates that the virtual machine dynamically obtains the ip address

NAME=ens33 #The device name of the NIC is ens33

DEVICE=ens33 #The device name of the NIC is ens33

ONBOOT=yes #Automatically activate network card when booting--》Automatically activate network card

IPADDR=192.168.0.178 #ip address

PREFIX=24 #subnet mask

#NETMASK=255.255.255.0 #subnet mask

GATEWAY=192.168.0.1 #Gateway

DNS1=114.114.114.114 #Specify preferred DNS server

3. Refresh network services

---》centos7：

service network restart

---》centos8:

Use ifens up 33

How to check Centos version:

Refresh the network service and check the ip address and gateway again

4. Test whether ping Baidu can surf the Internet

Ctrl+C Forcefully terminates ping
