systemd network configuration

Next, this section describes the network architecture and configuration process of the RADWARE project. Radware works in active/standby mode. The corresponding networking methods are divided into single-arm networking, dual-arm networking, and triangular transmission. I. Single-arm networkingThe following networking is called single-arm networking, which is a widely used networking method. This networking m

Now some hosts have multiple NICs how to configure each NIC with a different IP address for the same network segment:1. Use Ifconfig to see how many network cards are available: I'm hosts are Nic:eth0 and Eth8.An IP has been configured on the eth0 now I need to configure the IP address on the ETH82. First check that the NIC is well connected: for example, if the light on the interface is shining, the line

So the virtual machine has to configure a static IP, eliminating the hassle.System Redhat, other systems slightly different but roughly the sameWorkaround: Open VMware---> Edit---> Virtual Network editor--->vmnet8 (NAT) as an administrator, and view the subnet IP, such as my subnet ip:192.168.152.0, can also be modified to the IP you want, In order to conveniently chan
