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：
- ip addr
输出样例：
- 1: lo:<LOOPBACK,UP,LOWER_UP> 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 forever
- 2: venet0:<BROADCAST,POINTOPOINT,NOARP,UP,LOWER_UP> 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，输入命令：
- ip link
输出样例：
- 1: lo:<LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN mode DEFAULT
- link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
- 2: venet0:<BROADCAST,POINTOPOINT,NOARP,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN mode DEFAULT
- link/void
或者
- ip -s link
输出样例：
- 1: lo:<LOOPBACK,UP,LOWER_UP> 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
- 000000
- TX: bytes packets errors dropped carrier collsns
- 000000
- 2: venet0:<BROADCAST,POINTOPOINT,NOARP,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN mode DEFAULT
- link/void
- RX: bytes packets errors dropped overrun mcast
- 851566766670000
- TX: bytes packets errors dropped carrier collsns
- 30040342490000
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：
- yum provides ifconfig
输出样例：
- Loaded plugins: fastestmirror
- Loading mirror speeds from cached hostfile
- *base: centos.aol.in
- * extras: centos.aol.in
- * updates: centos.aol.in
- net-tools-2.0-0.17.20131004git.el7.x86_64 :Basic networking tools
- Repo:@base
- Matchedfrom:
- 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。
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。
- yum install net-tools
现在，你就可以像以往一样使用ifconfig命令了。
- ifconfig -a
输出样例：
- lo: flags=73<UP,LOOPBACK,RUNNING> mtu 16436
- inet 127.0.0.1 netmask 255.0.0.0
- inet6 ::1 prefixlen 128 scopeid 0x10<host>

尽情享受吧！
