在Linux中有三种查看ip地址的方法,下面我分别来介绍

1.ip address命令

使用ip address命令可以查看具体是ip信息

[root@lixian ~]#ip address
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:29:8b:2e:bb brd ff:ff:ff:ff:ff:ff
    inet 10.0.0.100/24 brd 10.0.0.255 scope global noprefixroute eth0
       valid_lft forever preferred_lft forever
    inet6 fe80::345d:38a5:8df5:e4e9/64 scope link noprefixroute 
       valid_lft forever preferred_lft forever
[root@lixian ~]#

ip adderss可以简写成 ip a

查看具体的指定网卡详细信息

[root@lixian ~]#ip address show eth0
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
    link/ether 00:0c:29:8b:2e:bb brd ff:ff:ff:ff:ff:ff
    inet 10.0.0.100/24 brd 10.0.0.255 scope global noprefixroute eth0
       valid_lft forever preferred_lft forever
    inet6 fe80::345d:38a5:8df5:e4e9/64 scope link noprefixroute 
       valid_lft forever preferred_lft forever
[root@lixian ~]#

ip address show eth0可以简写成ip a s eth0

2.ifconfig命令

使用ifconfig需要yum安装net-tools软件

[root@lixian ~]#yum -y install bash-completion

extras                                                      | 2.9 kB  00:00:00

Complete!

ifconfig eth0 可以指定某个网卡查看详细信息

[root@lixian ~]#ifconfig eth0
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 10.0.0.100  netmask 255.255.255.0  broadcast 10.0.0.255
        inet6 fe80::345d:38a5:8df5:e4e9  prefixlen 64  scopeid 0x20<link>
        ether 00:0c:29:8b:2e:bb  txqueuelen 1000  (Ethernet)
        RX packets 485  bytes 43391 (42.3 KiB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 294  bytes 35220 (34.3 KiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0
[root@lixian ~]#

3.hostname命令

hostname -i -I
-i 显示是IPV6和IPV4的信息
-I 只显示ip地址

[root@lixian ~]#hostname -i
fe80::345d:38a5:8df5:e4e9%eth0 10.0.0.100
[root@lixian ~]#hostname -I
10.0.0.100 
[root@lixian ~]#
