    One, mode one

    1. Modify/ETC/SYSCONFIG/NETWORK-SCRIPTS/IFCFG-ENP2S0 to: (Note: The file name must be the NIC device name)

        
   
      
     
    
    1. 
    
    2. DEVICE=enp2s0
      3.

    4. BOOTPROTO=static
      5.

    18. GATEWAY=10.0.57.1
      19.

    2.CP Ifcfg-enp2s0 for Ifcfg-enp2s0:1, and fix the ifcfg-enp2s0:1 content as:

        
   
      
     
    
    1. 
    
    2. DEVICE=enp2s0:1

    17. 
    
    18. GATEWAY=10.0.57.1
      19.

    3. Restart the NIC, and then ifconfig to see it. ?

    1. Configure multiple network cards directly in the/ETC/SYSCONFIG/NETWORK-SCRIPTS/IFCFG-ENP2S0,

    However, to use IP addr to see multiple IP information, the configuration is as follows: 
          
   
        
     
    
      1. 
    
      2. TYPE=Ethernet
        3. 
     
    
      3. 
    
      4. BOOTPROTO=none
        5. 
     
    
      5. 
    
      6. DEFROUTE=yes
        7. 
     
    
      7. 
    
      8. IPV4_FAILURE_FATAL=no
        9. 
     
    
      9. 
    
      10. IPV6INIT=yes
        11. 
     
    
      11. 
    
      12. IPV6_AUTOCONF=yes
        13. 
     
    
      13. 
    
      14. IPV6_DEFROUTE=yes
        15. 
     
    
      15. 
    
      16. IPV6_FAILURE_FATAL=no
        17. 
     
    
      17. 
    
      18. NAME=za209
        19. 
     
    
      19. 
    
      20. UUID=7e917b8e-2d35-4630-b314-2d64a2f1f52f
        21. 
     
    
      21. 
    
      22. ONBOOT=no
        23. 
     
    
      23. 
    
      24. DNS1=10.0.10.10
        25. 
     
    
      25. 
    
      26. DOMAIN=10.0.15.11
        27. 
     
    
      27. 
    
      28. HWADDR=B8:88:E3:73:7A:7B
        29. 
     
    
      29. 
    
      30. IPADDR=10.0.57.230
        31. 
     
    
      31. 
    
      32. PREFIX=24
        33.

      35. 
    
      36. IPADDR1=10.0.57.231
        37. 
     
    
      37. 
    
      38. PREFIX1=24
        39. 
     
    
      39. 
    
      40. GATEWAY1=10.0.57.1
        41. 
     
    
      41. 
    
      42. IPV6_PEERDNS=yes
        43. 
     
    
      43. 
    
      44. IPV6_PEERROUTES=yes
        45.

2. Restart the network card, using the IP addr command to view, shown as follows:

  
 
    
   
  
  1. 
  
  2.       2  :   Enp2s0  :    <  broadcast  Span class= "pun", multicast   up   lower_up  >   MTU  1500   Qdisc pfifo_fast state up Qlen  1000   
    3.

  4.      link  / ether b8  :  Span class= "lit" >88 :  e3  :  73  :  7a  :  7b   BRD FF  :  ff  :  ff  :  ff  :  ff  :  ff   
    5.
