查看IP

ifconfig

[root@localhost ~]# ifconfig
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        ether 52:54:00:8a:fe:e6  txqueuelen 1000  (Ethernet)
        RX packets 0  bytes 0 (0.0 B)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 0  bytes 0 (0.0 B)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

eth1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.10.69  netmask 255.255.255.0  broadcast 192.168.10.255
        inet6 fe80::a00:27ff:fe94:9b6c  prefixlen 64  scopeid 0x20<link>
        ether 08:00:27:94:9b:6c  txqueuelen 1000  (Ethernet)
        RX packets 737  bytes 75483 (73.7 KiB)
        RX errors 0  dropped 2  overruns 0  frame 0
        TX packets 114  bytes 12081 (11.7 KiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

lo: flags=73<UP,LOOPBACK,RUNNING>  mtu 65536
        inet 127.0.0.1  netmask 255.0.0.0
        inet6 ::1  prefixlen 128  scopeid 0x10<host>
        loop  txqueuelen 1000  (Local Loopback)
        RX packets 68  bytes 5912 (5.7 KiB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 68  bytes 5912 (5.7 KiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

这里修改 eth1
inet 192.168.10.69 id地址
netmask 255.255.255.0子网掩码
broadcast 192.168.10.255广播地址

修改eth1
