TYPE="Ethernet" # Network type, no need to change, the default is Ethernet, meaning Ethernet PROXY_METHOD="none" # Proxy mode: closed BROWSER_ONLY="no" # Just browser: no BOOTPROTO="none" # Boot protocol for network card: DHCP [Chinese name: Dynamic Host Configuration Protocol]
DEFROUTE="yes" # Default route: yesIPV4_FAILURE_FATAL="yes" # Disable IPV4 fatal error detection: noIPV6INIT="yes" # Whether IPV6 is automatically initialized: yesIPV6_AUTOCONF="yes" # Whether IPV6 is automatically configured: yesIPV6_DEFROUTE="yes" # Can IPV6 be the default route: yesIPV6_FAILURE_FATAL="no" # Disable IPV6 fatal error detection: noIPV6_ADDR_GEN_MODE="stable-privacy" # IPV6 address generation model: stable-privacy
NAME="em2" # Network card physical device name UUID="b9cf0ca7-ddc9-4c55-9cea-ce04919f6514" # Universal unique identifier, each network card will have, can not be repeated, otherwise two Linux only one network card can be used DEVICE="em2" # Network card device name, must be the same as the `NAME` value ONBOOT="yes" # Whether to start the network card at boot, if you want the network card to start at boot or control the network card through `systemctl restart network` IPADDR="172.20.41.96" # IP address PREFIX="24" # Configure subnet mask GATEWAY="172.20.41.65" # Gateway DNS1="202.96.209.133" # DNS
IPV6_PRIVACY="no"

4. Restart the network card after the modification is completed

systemctl restart network
