(2) the edit mode (Insert Mode): This mode is the edit mode can be entered in the text in this mode, since vi editor defaults to command mode, you enter edit mode requires keyboard to type the letter "i" enters Edit mode. Keyboard Type "Esc" to exit this mode represents the command mode.

1. Configure virtual machine network
(1) network setup is complete, start the virtual host. Enter the username: root, log on CentOS.
(2) shut down the system and turn off the firewall from the system startup, the following command input terminal is closed firewall virtual machine, while closing SELinux service.
# Closed "system firewall" command
systemctl stop firewalld.service
# Closed "system firewall" command from the start
systemctl disable firewalld.service
# Close the "SELinux" service command
setenforce 0
# Close the "SELinux" system since the launch of the service system
vi /etc/selinux/config
# Modify the content SELINUX = disabled
Open CentOS network interface profile (required vary according to the actual situation of the network computer configuration file, said document fails to be input to "vi / etc / sysconfig / network-scripts /" Tab key using the keypad configuration file to find the network) ,
Content
BOOTPROTO=static IPADDR=192.168.1.101 NETMASK=255.255.255.0 GATEWAY=192.168.1.1 ONBOOT=yes
2. Configure virtual machine outside the network
# Edit network file
vi /etc/sysconfig/network
# Add content
NETWORKING=yes
HOSTNAME=master
# Edit resolv.conf file
we /etc/resolv.conf
# Resolv.conf file content (8.8.8.8 DNS server provided by Google, DNS server can be configured according to the actual situation of local network
nameserver 192.168.1.1
nameserver 8.8.8.8
nameserver 8.8.8.4
# Editor restart the virtual NIC
service network restart
Verify whether the configuration input on the virtual host ping 192.168.1.151 (IP host address of the host, the replacement of the actual situation)
two,
This completes the clone virtual machine.
