我装的是rhel7 服务器版本(在virtualbox虚拟机里),安装后默认不启动网络,另外还有很多命令也不能用,比如ifconfig, yum-config-manager等。

切换root用户

在/etc/sysconfig/network-scripts目录下有一个和你网卡有关的文件,我的是  ifcfg-enp0s3

,并修改为ONBOOT=on。然后即可链接网络

因为ifconfig在net-tools包里,yum-config-manager在yum-util包里,现在我的电脑里没有源,有不能通过yum管理工具添加源,也挂载不了光盘,所以接下来手动添加一个163的yum源:

cd /etc/yum.repo.d
vi centos7.repo
/ *输入一下内容
[centos7]
name=centos7
baseurl=http://mirrors.163.com/centos/7/os/x86_64/
gpgcheck=
gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-7
*/
yum clean all
yum update
yum makecache

即可。

现在就可以安装需要的东西了。

yum install yum-util -y
yum install net-tools -y

现在ifconfig, yum-config-manager都可以用了。
