如果使用ifconfig命令查看网卡信息是，没有反应，需要我们自己安装ifconfig [root@localhost ~]# yum search all ifconfig Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * ...... python36-ifcfg.noarch : Python cross-platform network interface discovery (ifconfig/ipconfig/ip) ................. python36-psutil.x86_64 : A process and system utilities module for Python [root@localhost ~]# yum install -y net-tools Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile ............. Installed: net-tools.x86_64 0:2.0-0.25.20131004git.el7 Complete! [root@localhost ~]# which ifconfig /usr/sbin/ifconfig [root@localhost ~]# ifconfig em1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 ........ lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536 ...... ovs-ext: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet6 fe80::480d:7fff:febb:9741 prefixlen 64 scopeid 0x20<link> .............. ovs-int: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet6 fe80::cce7:42ff:feee:3c4c prefixlen 64 scopeid 0x20<link> ............... ovs-tun: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet6 2403:6a40:0:123:8c6a:64ff:fe08:344c prefixlen 64 scopeid 0x0<global> ................... phy-ext: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 ............... phy-int: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 .............. 以上就是安装ifconfig 教程 查看版本：cat /etc/redhat-release 升级系统：yum update 安装wget:yum -y install wget |
