How to configure the IP address for linux
How to configure the IP address for linux? In view of this problem, this article introduces the corresponding analysis and answers in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible way.
Rhel7/centos7 has added a new IP address configuration tool, but the previous version does not, so you can refer to two methods here.
Method 1: nmcli tool (new version of the system is available)
Step 1 check the name of the network card
[root@localhost Desktop] # nmcli connection
As shown in the figure, NAME corresponds to the name of the network card, and DEVICE corresponds to the hardware identification of the network card, and the name can be modified.
The beginning of vir is a virtual network card or virtual device, so here you need to configure the address of the network card that begins with eno.
Step 2 configure the IP address
[root@localhost Desktop] # nmcli connection modify "eno16777736" ipv4.addresses "172.20.10.3 go 24" address and mask [root@localhost Desktop] # nmcli connection modify "eno16777736" ipv4.gateway "172.20.10.1" Gateway [root@localhost Desktop] # nmcli connection modify "eno16777736" ipv4.dns "114.114.114" Domain name Server [root@localhost Desktop] # nmcli connection modify "eno16777736" ipv4.method manual manually instead of DHCP [root@localhost Desktop ] # nmcli connection modify "eno16777736" connection.autoconnect yes boot [root@localhost Desktop] # nmcli connection up "eno16777736" enable the interface
Step 3 check the IP address and test
Method 2: edit the network card configuration file through the vi editor (systems below RHEL7)
[root@localhost Desktop] # vi / etc/sysconfig/network-scripts/ifcfg-eno16777736
Just modify the corresponding information in the following figure
Press I to enter edit mode
Press esc and then enter: wq to save exit
Press esc and then enter: Q! Exit for not saving
After the modification, restart the network service through service network restart
