linux系统中如何查看本机IP

001、利用net-tools工具下的 ifoconfig命令

root@ubuntu01:/home/software# ifconfig | head -n 3
ens32: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.186.134  netmask 255.255.255.0  broadcast 192.168.186.255
        inet6 fe80::5e5e:ac9b:46ad:b6a0  prefixlen 64  scopeid 0x20<link>

002、利用ip addr命令

root@ubuntu01:/home/software# ip addr
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 fq_codel state UP group default qlen 1000
    link/ether 00:0c:29:8c:4d:05 brd ff:ff:ff:ff:ff:ff
    altname enp2s0
    inet 192.168.186.134/24 brd 192.168.186.255 scope global dynamic noprefixroute ens32
       valid_lft 1679sec preferred_lft 1679sec
    inet6 fe80::5e5e:ac9b:46ad:b6a0/64 scope link noprefixroute
       valid_lft forever preferred_lft forever

003、利用hostname -I命令

root@ubuntu01:/home/software# hostname -I
192.168.186.134

004、利用ip route命令

root@ubuntu01:/home/software# ip route get 1.2.3.4 | awk '{print $7}'
192.168.186.134

005、

root@ubuntu01:/home/software# nmcli -p device show
