centos7最小安装后网络配置

ip addr查看网络接口

[zhujiang@localhost 6379]$ ip addr

vi /etc/sysconfig/network-script/ifcfg-eno16777736

修改onboot为yes

安装ifconfig
[zhujiang@localhost ~]$ sudo yum provides ifconfig
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
 * base: mirrors.pubyun.com
 * extras: mirrors.pubyun.com

net-tools-2.0-0.17.20131004git.el7.x86_64 : Basic networking tools
Repo        : base
Matched from:
Filename    : /sbin/ifconfig

从上面可以知道ifconfig在net-tools包里
yum install net-tools
