Centos Linux为网卡配置临时的IP地址

使用ifconfig命令配置临时IP地址

[root@sre01 ~]# ifconfig ens36
ens36: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 172.16.156.128  netmask 255.255.255.0  broadcast 172.16.156.255
        inet6 fe80::e778:fe94:3756:fa71  prefixlen 64  scopeid 0x20<link>
        ether 00:0c:29:c0:78:db  txqueuelen 1000  (Ethernet)
        RX packets 3  bytes 746 (746.0 B)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 12  bytes 1496 (1.4 KiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0


[root@sre01 ~]# ifconfig ens36 172.16.156.100 netmask 255.255.255.0


[root@sre01 ~]# ifconfig ens36
ens36: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 172.16.156.100  netmask 255.255.255.0  broadcast 172.16.156.255
        inet6 fe80::e778:fe94:3756:fa71  prefixlen 64  scopeid 0x20<link>
        ether 00:0c:29:c0:78:db  txqueuelen 1000  (Ethernet)
        RX packets 3  bytes 746 (746.0 B)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 12  bytes 1496 (1.4 KiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

[root@sre01 ~]#

清空临时配置的IP地址信息

[root@sre01 ~]# ifconfig ens36 0

[root@sre01 ~]# ifconfig ens36
ens36: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet6 fe80::e778:fe94:3756:fa71  prefixlen 64  scopeid 0x20<link>
        ether 00:0c:29:c0:78:db  txqueuelen 1000  (Ethernet)
        RX packets 3  bytes 746 (746.0 B)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 12  bytes 1496 (1.4 KiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0
