在CentOS最小化服务器版本中如何查找网卡IP和其它详细信息?

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,输入以下命令:

  1. ip addr

输出样例:

  1. 1: lo:<LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN
  2. link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
  3. inet 127.0.0.1/8 scope host lo
  4. inet6 ::1/128 scope host
  5. valid_lft forever preferred_lft forever
  6. 2: venet0:<BROADCAST,POINTOPOINT,NOARP,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN
  7. link/void
  8. inet 127.0.0.1/32 scope host venet0
  9. 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,输入命令:

  1. ip link

输出样例:

  1. 1: lo:<LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN mode DEFAULT
  2. link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
  3. 2: venet0:<BROADCAST,POINTOPOINT,NOARP,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN mode DEFAULT
  4. link/void

或者

  1. ip -s link

输出样例:

  1. 1: lo:<LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN mode DEFAULT
  2. link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
  3. RX: bytes packets errors dropped overrun mcast
  4. 000000
  5. TX: bytes packets errors dropped carrier collsns
  6. 000000
  7. 2: venet0:<BROADCAST,POINTOPOINT,NOARP,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN mode DEFAULT
  8. link/void
  9. RX: bytes packets errors dropped overrun mcast
  10. 851566766670000
  11. TX: bytes packets errors dropped carrier collsns

在CentOS 7最小化服务器版本中如何启用并使用“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。要完成这项任务,输入以下命令:

  1. yum provides ifconfig

输出样例:

  1. Loaded plugins: fastestmirror
  2. Loading mirror speeds from cached hostfile
  3. *base: centos.aol.in
  4. * extras: centos.aol.in
  5. * updates: centos.aol.in
  6. net-tools-2.0-0.17.20131004git.el7.x86_64 :Basic networking tools
  7. Repo:@base
  8. Matchedfrom:
  9. Filename:/usr/sbin/ifconfig

或者你也可以使用以下命令。

  1. 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。

就像你在上面的输出中所看到的,net-tools包提供了ifconfig命令。因此,让我们安装net-tools包来使用ifconfig命令。

  1. yum install net-tools

现在,你就可以像以往一样使用ifconfig命令了。

  1. ifconfig -a

输出样例:

  1. lo: flags=73<UP,LOOPBACK,RUNNING> mtu 16436
  2. inet 127.0.0.1 netmask 255.0.0.0
  3. inet6 ::1 prefixlen 128 scopeid 0x10<host>
