If CentOS 7 is unable to automatically obtain an IP address, you can try the following solutions:<\/p>\n

    \n
  1. Check the network connection: make sure the Ethernet cable or Wi-Fi connection is working properly without any disconnection or faults.<\/li>\n
  2. Check the network configuration: open the terminal, type the command “ifconfig -a” to check the status of network interfaces, make sure the network interfaces are functioning properly. You can use the command “nmcli connection show” to view the configuration information of network connections.<\/li>\n
  3. Restart the network service by entering the command “systemctl restart network” to try to retrieve the IP address again.<\/li>\n
  4. Setting up network connections: You can use commands such as “nmtui” or “nmcli” to configure network connections, manually entering details such as IP address, subnet mask, and gateway.<\/li>\n
  5. Check the DHCP service: Make sure the DHCP server is running properly by using the command “systemctl status dhcpd” or “systemctl status NetworkManager” to check the status of the DHCP service.<\/li>\n<\/ol>\n

    If the above methods do not solve the problem, there may be other issues in the network configuration. It is recommended to check the system log file (such as \/var\/log\/messages) for error messages, or contact the network administrator or service provider for further investigation and resolution.<\/p>\n","protected":false},"excerpt":{"rendered":"
