linux 中查看、抽取本机IP

方法1：

1、查看ip

[root@centos7pc1 test]# ifconfig | head
ens32: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.65.153  netmask 255.255.255.0  broadcast 192.168.65.255
        inet6 fe80::cf50:d12:760f:c2f1  prefixlen 64  scopeid 0x20<link>
        ether 00:0c:29:c5:9b:14  txqueuelen 1000  (Ethernet)
        RX packets 25490  bytes 26858429 (25.6 MiB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 12793  bytes 1189793 (1.1 MiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

lo: flags=73<UP,LOOPBACK,RUNNING>  mtu 65536

2、提取ip

[root@centos7pc1 test]# ifconfig | grep "inet" | awk 'NR == 1{ print $2 }'
192.168.65.153

方法2：

1、查看ip

[root@centos7pc1 test]# 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: ens32: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
    link/ether 00:0c:29:c5:9b:14 brd ff:ff:ff:ff:ff:ff
    inet 192.168.65.153/24 brd 192.168.65.255 scope global noprefixroute dynamic ens32
       valid_lft 1770sec preferred_lft 1770sec
    inet6 fe80::cf50:d12:760f:c2f1/64 scope link noprefixroute
       valid_lft forever preferred_lft forever
3: virbr0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN group default qlen 1000
    link/ether 52:54:00:3a:fc:95 brd ff:ff:ff:ff:ff:ff
    inet 192.168.122.1/24 brd 192.168.122.255 scope global virbr0
       valid_lft forever preferred_lft forever
4: virbr0-nic: <BROADCAST,MULTICAST> mtu 1500 qdisc pfifo_fast master virbr0 state DOWN group default qlen 1000
    link/ether 52:54:00:3a:fc:95 brd ff:ff:ff:ff:ff:ff

2、提取ip

[root@centos7pc1 test]# ip a | grep "inet" | grep "ens" | awk '{print $2}' | cut -d "/" -f 1
192.168.65.153
