In general, centos ip address command to view
ip addr
ip address
To configure ip address,
In the / etc / sysconfig / network-scripts / ifcfg-xxx file
1, to obtain dynamic ip (provided that your router has opened DHCP)
Modify the network card configuration file vi / etc / sysconfig / network-scripts / ifcfg-ens32 (last name for the card)
Dynamic IP addresses need to modify two places
（1）bootproto=dhcp
（2）onboot=yes
After the modification restart the network services to systemctl restart network
[root@mini ~]# systemctl restart network [root@mini ~]#
Such a dynamic IP address configuration is set up, this time to look at the ip addr can see already acquired an IP address, and the Internet (ping Baidu)
2, configure a static IP address
Set a static IP address and dynamic iIP almost as well as to modify the network card configuration file vi / etc / sysconfig / network-scripts / ifcfg-ens32 (last name for the card)
（1）bootproto=static
（2）onboot=yes
(3) add the final few lines, IP address, subnet mask, gateway, dns server
IPADDR=192.168.1.160 NETMASK=255.255.255.0 GATEWAY=192.168.1.1 DNS1=119.29.29.29 DNS2=8.8.8.8
(4) Network Service Restart
[root@mini ~]# systemctl restart network [root@mini ~]#
DNS server with only one I use two free dns server, view the IP address, network test
