nmcli 是NetworkManager的管理工具，使得网络配置更加简单

nmcli配置链路:

此链路在 desktopX 使用下面的地址 172.16.3.20/255.255.255.0
此链路在 serverX 使用下面的地址 172.16.3.25/255.255.255.0

desktop:

[root@desktop0 ~]# nmcli device status all

nmcli 配置ipv6:

1. desktopX 上的地址应该是 2003:acl8::305/64
2. serverX 上的地址应该是 2003:acl8::30a/64

[root@desktop0 ~]# nmcli connection modify "System eth0"

ipv6.addresses 2003:ac18::305/64 ipv6.method manual

connection.autoconnect on
[root@desktop0 ~]# nmcli connection up "System eth0"
Connection successfully activated (D-Bus active path:

/org/freedesktop/NetworkManager/ActiveConnection/1)

[root@server0 ~]# nmcli connection modify "System eth0"
ipv6.addresses 2003:ac18::30a/64 ipv6.method manual
connection.autoconnect on
[root@server0 ~]# nmcli connection up "System eth0"
Connection successfully activated (D-Bus active path:

/org/freedesktop/NetworkManager/ActiveConnection/7)

nmcli 配置ipv4:

配置IPv4 网络
nmcli connection modify "System eth0" ipv4.addresses
"172.25.0.10/24 172.25.0.254" ipv4.dns 172.25.254.254
ipv4.method manual connection.autoconnect on
nmcli connection up "System eth0"
