CentOS7中mini使用ifconfig的方法是什么

CentOS 7版系统查看网络信息的命令

CentOS 7最小化系统，使用"ip addr"和"ip link"命令来查找网卡详情。要知道统计数据，可以使用"ip -s link"。

要查看网卡细节：ip addr

[root@linuxprobe ~]#ip addr1: lo:  mtu 16436 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   inet6 ::1/128 scope host      valid_lft forever preferred_lft forever2: venet0:  mtu 1500 qdisc noqueue state UNKNOWN   link/void   inet 127.0.0.1/32 scope host venet0   inet 192.168.1.101/32 brd 192.168.1.101 scope global venet0:0

要查看网络接口统计数据：ip link

[root@linuxprobe ~]#ip link1: lo:  mtu 16436 qdisc noqueue state UNKNOWN mode DEFAULT   link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:002: venet0:  mtu 1500 qdisc noqueue state UNKNOWN mode DEFAULT   link/void

或者使用：ip -s link

[root@linuxprobe ~]#ip -s link1: lo:  mtu 16436 qdisc noqueue state UNKNOWN mode DEFAULT   link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00   RX: bytes  packets  errors  dropped overrun mcast     0          0        0       0       0       0         TX: bytes  packets  errors  dropped carrier collsns   0          0        0       0       0       0      2: venet0:  mtu 1500 qdisc noqueue state UNKNOWN mode DEFAULT   link/void   RX: bytes  packets  errors  dropped overrun mcast     8515667    6667     0       0       0       0         TX: bytes  packets  errors  dropped carrier collsns   300403     4249     0       0       0       0

在CentOS 7最小化服务器版本中启用"ifconfig"命令

如果你不知道在哪里可以找到ifconfig命令，请按照以下简单的步骤来找到它。

首先，让我们找出哪个包提供了ifconfig命令:

[root@linuxprobe ~]# yum provides ifconfigLoaded plugins: fastestmirrorLoading mirror speeds from cached hostfile* base: centos.aol.in* extras: centos.aol.in* updates: centos.aol.innet-tools-2.0-0.17.20131004git.el7.x86_64 : Basic networking toolsRepo        : @baseMatched from:Filename    : /usr/sbin/ifconfig

或者你也可以使用以下命令

yum whatprovides ifconfig

这里，"provides"或者"whatprovides"开关用于找出某个包提供了某些功能或文件。

net-tools包提供了ifconfig命令。因此，安装net-tools包也可以使用ifconfig命令。

安装net-tools包

yum install net-tools

现在，你就可以像以往一样使用ifconfig命令了。

[root@linuxprobe ~]# ifconfig -alo: flags=73  mtu 16436       inet 127.0.0.1  netmask 255.0.0.0       inet6 ::1  prefixlen 128  scopeid 0x10       loop  txqueuelen 0  (Local Loopback)       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 0venet0: flags=211  mtu 1500       inet 127.0.0.1  netmask 255.255.255.255  broadcast 0.0.0.0  destination 127.0.0.1       unspec 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00  txqueuelen 0  (UNSPEC)       RX packets 7073  bytes 8549159 (8.1 MiB)       RX errors 0  dropped 0  overruns 0  frame 0       TX packets 4611  bytes 359201 (350.7 KiB)       TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0venet0:0: flags=211  mtu 1500       inet 192.168.1.101  netmask 255.255.255.255  broadcast 192.168.1.101  destination 192.168.1.101       unspec 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00  txqueuelen 0  (UNSPEC)
