? The two-Nic binding implementation is the use of two network card virtual become a network card, the aggregation of the device appears to be a separate Ethernet interface device, the popular point is that two network cards have the same IP address and parallel link aggregation into a logical link work. Depending on the features that the switch can support, the most common is a dual-NIC binding that is set as the primary standby mode. There are seven types of NIC binding modes in Linux: 0. Roun

Linux Network attribute configuration commands and management details
I. Linux Network attribute Configuration
1. Network Access for Linux Hosts
IP/NETMASK: Implement Local Network Communication
Routing (GATEWAY): Cross-network communication is supported.
DNS server address: Host Name-based communication. Linux can have three DNS addresses.
When the first address goes down, it will find its standby address. If the first address cannot be resolved, it will stop.
2. Network attribute configuration
Change the hostname of centos-valid permanentlyProcedure
Uname-a (or hostname) can see the hostname. The modification steps are as follows:
uname -aView hostname
hostname newnameModify to make the hostname take effect immediately.
vi /etc/hostsChange the original hostname to newname.
vi /etc/sysconfig/networkModify the original hostnameNewname, reboot also takes effect after restart
Reboot restart,uname -aCheck again. Done!
