Virtual machine configuration network

linux Three modes of network ：

NAT Pattern ：

1. edit -- Virtual network adapter --NAT Pattern

 

2. Set up -- network adapter --NAT Pattern -- Set the network segment to be consistent with the host

So the subnet here IP The network segment is 192.168.80.0. The subnet mask is ：255.2555.255.0

The host machine ip Address the query

1. Turn on the Internet and internet Set up

2. Change adapter options

3. See here ip The address is 192.168.80.1

Automatic access to IP Address

[[email protected] ~]# nmcli connection modify "ens33" ipv4.method auto connection.autoconnect yes 

[[email protected] ~]# nmcli connection down ens33 

[[email protected] ~]# nmcli connection up ens33 // Restart NIC , Refresh ip Address

Manual access ip Address

[[email protected] ~]# nmcli connection modify ens33 ipv4.method manual ipv4.addresses 192.168.80.30/24 ipv4.gateway 192.168.80.2 ipv4.dns 8.8.8.8 connection.autoconnect yes
[[email protected] ~]# nmcli connection down ens33 

[[email protected] ~]# nmcli connection up ens33  // Restart NIC , Refresh ip Address

Changing configuration files , configure network

 

Inquire about ip Address ：ip a

Query the default gateway ：ip r

Inquire about DNS：cat /etc/resolv.conf 

Bridging mode ：
