如何查看CentOS Linux上面的IP地址信息（主要针对CentOS 7.x）

“用过Linux的很多都知道查看IP的命令是ifconfig，但是这个在CentOS 7.x默认是不存在的命令，那如何来查看CentOS 7的IP信息呢？ ”

对于CentOS 5.x, 6.x,来说，查看IP信息的命令是ifconfig，这个命令是在系统里面默认就带的，但是自从有了CentOS 7之后，很多人发现这个命令不存在了，执行ipconfig命令之后是这样的。

[root@localhost ~]# ipconfig

-bash: ipconfig: command not found

那如何来查看CentOS 7的IP信息呢？

# ip addr

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN

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: enp5s0f0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP qlen 1000

link/ether 00:1b:21:bb:f9:fc brd ff:ff:ff:ff:ff:ff

inet 192.168.1.10/29 brd 192.168.1.15 scope global enp5s0f0

valid_lft forever preferred_lft forever

inet6 fe80::21b:21ff:febb:f9fc/64 scope link

valid_lft forever preferred_lft forever

3: enp1s0f0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN qlen 1000

link/ether 00:25:90:35:de:e4 brd ff:ff:ff:ff:ff:ff

4: enp1s0f1: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN qlen 1000

link/ether 00:25:90:35:de:e5 brd ff:ff:ff:ff:ff:ff

5: enp5s0f1: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN qlen 1000

link/ether 00:1b:21:bb:f9:fd brd ff:ff:ff:ff:ff:ff

在这里，我们看到了5个网络设备，enp5s0f0上面的192.168.1.10/29就是我们的IP地址。

另外还可以安装iconfig命令，首先需要知道哪个工具包里面有iconfig命令，如果不知道的话，可以用yum provides ifconfig 来查看，通过此命令知道是net-tools

# yum install net-tools

安装好之后，我们熟悉的iconfig命令就可以用了

# ifconfig
