To regenerate the network card configuration file for CentOS 7, follow these steps:<\/p>\n

    \n
  1. Open a terminal window and log in to the system as an administrator.<\/li>\n
  2. Navigate to the directory where the network card configuration file is located and use the following command:<\/li>\n<\/ol>\n
    cd \/etc\/sysconfig\/network-scripts\/\r\n<\/code><\/pre>\n
      \n
    1. To check the current network card configuration file, use the following command:<\/li>\n<\/ol>\n
      ls ifcfg-*\r\n<\/code><\/pre>\n
        \n
      1. If you need to regenerate the configuration file for a specific network card, you can first backup the original configuration file and then use the following command (assuming the network card that needs to be regenerated is eth0):<\/li>\n<\/ol>\n
        cp ifcfg-eth0 ifcfg-eth0.bak\r\n<\/code><\/pre>\n
          \n
        1. Delete the existing network card configuration file and use the following command:<\/li>\n<\/ol>\n
          rm -f ifcfg-eth0\r\n<\/code><\/pre>\n
            \n
          1. Create a new network interface configuration file using a text editor (such as vi) by using the following command:<\/li>\n<\/ol>\n
            vi ifcfg-eth0\r\n<\/code><\/pre>\n
              \n
            1. “Enter the new network card configuration information in the editor, for example:”<\/li>\n<\/ol>\n
              DEVICE=eth0\r\nBOOTPROTO=dhcp\r\nONBOOT=yes\r\n<\/code><\/pre>\n
              This is an example configuration that automatically obtains an IP address using DHCP. Modify the configuration information according to actual needs.<\/p>\n
                \n
              1. Save and close the editor.<\/li>\n
              2. To restart the network service, use the following command:<\/li>\n<\/ol>\n
                systemctl restart network\r\n<\/code><\/pre>\n
                After regenerating the network card configuration file, the network card will start with the new configuration.<\/p>\n","protected":false},"excerpt":{"rendered":"
