1.如果连不了网,执行以下命令,确保没有vbr
[student@room9pc01 ~]$ virsh
欢迎使用 virsh，虚拟化的交互式终端。
输入：'help' 来获得命令的帮助信息
'quit' 退出
virsh # net-destroy vbr
网络 vbr 被删除
virsh # exit
2.创建一台虚拟机
[student@room9pc01 ~]$ virt-manager
[student@room9pc01 ~]$ clone-auto7 创建虚拟机
Enter VM number: 1
VM stu_node01 Create [ 确定 ]
3.在虚拟机器上配置ip
[root@localhost ~]# nmcli connection modify eth0 ipv4.method manual ipv4.addresses 192.168.4.2/24 connection.autoconnect yes
[root@localhost ~]# nmcli connection up eth0
[ 274.964923] IPv6: ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready
Connection successfully activated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/5)
[root@localhost ~]# hostnamectl set-hostname postgresql
[root@localhost ~]# exit
logout

4.用真机传送文件到虚拟机中
[student@room9pc01 ~]$ scp '/home/student/桌面/postgresql-10.1.tar.bz2' root@192.168.4.2:/root

5.用真机链接虚拟机器
[student@room9pc01 ~]$ ssh root@192.168.4.2
