在linux / unix 中
很習慣用 ifconfig -a 指令來檢查網路的狀態
但是在 CentOS 7 最小安裝完後
想要下這個指令
卻發現找不到了
原來是用 ip addr 這個指令來取代了
[root@example-08 ]# 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: ens192: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
link/ether 00:0c:xx:xx:xx:83 brd ff:ff:ff:ff:ff:ff
inet 192.168.80.8/24 brd 192.168.200.255 scope global noprefixroute ens192
valid_lft forever preferred_lft forever
inet6 fe80::xxxx:xxxx:fe30:2e83/64 scope link
valid_lft forever preferred_lft forever
如果還是跟我一樣習慣舊指令的話
可以安裝 net-tools 套件
[root@example-08 ]# yum install net-tools
