Centos7默认显示IP地址的命令

 

 

 

#获取所有网卡的IP地址

[root@clf ~]# ip  a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host
       valid_lft forever preferred_lft forever
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
    link/ether 00:0c:29:eb:ea:8d brd ff:ff:ff:ff:ff:ff
    inet 10.0.0.100/24 brd 10.0.0.255 scope global noprefixroute eth0

    inet6 fe80::3310:9d15:9ee4:43e8/64 scope link noprefixroute

                                 ip   a   =     ip  address   

[root@clf ~]# ip address

#单独查看某个网卡的IP地址

[root@clf ~]# ip  a  s  eth0
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000

ifconfig是Centos6默认显示IP地址的命令

[root@clf ~]# yum install  -y  net-tools

hostname

#显示所有的IP地址，会显示IPv6的地址

[root@clf ~]# hostname -i
fe80::3310:9d15:9ee4:43e8%eth0 10.0.0.100

#只显示IPv4地址

[root@clf ~]# hostname -I
10.0.0.100

 

 

 

#如何获取到公网地址

[root@clf ~]# curl  ifconfig.me
