Check IP address and interface status
$ ifconfig -a

Note: Interface/LAN interface name is ens33
Before configuring manual IP address in system , you need to disable NetworkManager service (GUI)
Edit file /etc/network/interfaces to configure static/manually ip address
$ sudo vim /etc/network/interfaces
# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback
#====Change Parameter for 1st interface============#
auto ens33
iface ens33 inet static
address 192.168.0.70
netmask 255.255.255.0
gateway 192.168.0.254
dns-nameservers 8.8.8.8 4.4.2.2
Start networking service
$ sudo systemctl start networking
$ sudo systemctl enable networking
Now reboot system
$ sudo reboot
After reboot check ip status
$ ifconfig

Assign IP address on another interface
Edit networking config file and below parameter
$ sudo vim /etc/network/interfaces
#====Change Parameter for 2nd interface============#auto ens38
iface ens38 inet static

Restart networking service
$ sudo systemctl restart networking
