Linux cannot connect to the Internet

After using vim to open the file, you will see the configuration of the network card

Among them DEVICE is the name of the network card, whether BOOTPROTO is static or dynamic, IPADDR is the IP address, MASK is the subnet mask, GATEWAY is the gateway, and ONBOOT is the network card switch status. For example, the gateway is 192.168.229.2, and then ping the gateway to see if it can be pinged. .
