This article will explain in detail how to configure dynamic IP and static IP in Linux system. The editor thinks it is very practical, so I share it with you for reference. I hope you can get something after reading this article.

1. Configure dynamic IP (dhcp) the operating system for this example is Centos 7.

\ 1. Enter the network script configuration directory:

Cd / etc/sysconfig/network-scripts/\ 2. Locate the file corresponding to the network device:

The network device in this example is ens32, so the network profile is ifcfg-ens32.

\ 3. Modify the network configuration file (ifcfg-ens32 in this example) as follows:

TYPE= "Ethernet" PROXY_METHOD= "none" BROWSER_ONLY= "no" BOOTPROTO= "dhcp" NM_CONTROLLED= "no" DEFROUTE= "yes" IPV4_FAILURE_FATAL= "no" IPV6INIT= "yes" IPV6_AUTOCONF= "yes" IPV6_DEFROUTE= "yes" IPV6_FAILURE_FATAL= "no" IPV6_ADDR_GEN_MODE= "stable-privacy" NAME= "ens32" UUID= 0d683ed8-ffc5-4609-b05c-e7e1cc65a17e "DEVICE=" ens32 "ONBOOT=" yes: the key points in this document are as follows:

BOOTPROTO= "dhcp" (indicates that the IP acquisition mode is automatic IP acquisition)

ONBOOT= "yes" (indicates that this network device starts with the system)

\ 4. Restart the network by running the following command, as follows:

Systemctl restart network2. Configure static IP (static) the operating system for this example is Centos 7.

\ 1. Enter the network script configuration directory:

Cd / etc/sysconfig/network-scripts/\ 2. Locate the file corresponding to the network device:

The network device in this example is ens32, so the network profile is ifcfg-ens32.

\ 3. Modify the network configuration file (ifcfg-ens32 in this example) as follows:

HWADDR= "00:0C:29:E3:68:90" TYPE= "Ethernet" BOOTPROTO= "static" IPADDR=192.168.213.128 NETMASK=255.255.255.0 GATEWAY=192.168.213.2 DNS1=8.8.8.8 DNS2=233.5.5.5 DEFROUTE= "yes" yes "PEERROUTES=" yes "IPV4_FAILURE_FATAL=" no "IPV6INIT=" yes "IPV6_AUTOCONF=" yes "IPV6_DEFROUTE=" yes "IPV6_PEERDNS=" yes "IPV6_PEERROUTES=" yes "IPV6_FAILURE_FATAL=" no "IPV6_ADDR_GEN_MODE= "stable-privacy" NAME= "ens32" UUID= "5dbbd6a6-251b-4e0e-b0af-9fac91b6b79a" DEVICE= "ens32" ONBOOT= "yes" note: the key points in this file need to pay attention to the following:

HWADDR= "00:0C:29:E3:68:90" (the MAC address of the network device)

BOOTPROTO= "static" (indicates that the IP acquisition mode is to get static IP)

IPADDR=192.168.213.128 (set static IP address)

NETMASK=255.255.255.0 (set subnet mask)

GATEWAY=192.168.213.2 (set Gateway)

DNS1=8.8.8.8 and DNS2=233.5.5.5 (set DNS address)

ONBOOT= "yes" (indicates that this network device starts with the system)

\ 4. Edit the DNS parsing file / etc/resolv.conf and add the DNS information set above, as follows:

Nameserver 8.8.8 nameserver 233.5.5.5\ 5. Restart the network by running the following command, as follows:
