CentOS 7最小化安裝後找不到‘ifconfig’命令——修復小提示
就像我們所知道的,“ifconfig”命令用於配置GNU/Linux系統的網絡接口。它顯示網絡接口卡的詳細信息,包括IP地址,MAC地址,以及網絡接口卡狀態之類。但是,該命令已經過時了,而且在最小化版本的RHEL 7以及它的克隆版本CentOS 7,Oracle Linux 7和Scientific Linux 7中也找不到該命令。

在CentOS最小化服務器版本中如何查找網卡IP和其它詳細信息?
CentOS 7最小化系統,使用“ip addr”和“ip link”命令來查找網卡詳情。要知道統計數據,可以使用“ip -s link”。
要查看網卡細節,輸入以下命令:
- ip addr
輸出樣例:
- 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
要查看網絡接口統計數據,輸入命令:
- ip link
輸出樣例:
- 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
輸出樣例:
- 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

在CentOS 7最小化服務器版本中如何啟用並使用“ifconfig”命令?
如果你不知道在哪裏可以找到ifconfig命令,請按照以下簡單的步驟來找到它。首先,讓我們找出哪個包提供了ifconfig命令。要完成這項任務,輸入以下命令:
- yum provides ifconfig
輸出樣例:
- 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
這裏,“provides”或者“whatprovides”開關用於找出某個包提供了某些功能或文件。
就像你在上面的輸出中所看到的,net-tools包提供了ifconfig命令。因此,讓我們安裝net-tools包來使用ifconfig命令。
- yum install net-tools
現在,你就可以像以往一樣使用ifconfig命令了。
- ifconfig -a
輸出樣例:
- 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>
