Editing Setting ip Static Ubuntu 20.04 LTS Server

Cek ip server :
 ip a
 
 akan tampil seperti ini : (CONTOH)
 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever
 2: enp1s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000
    link/ether 00:1d:97:b5:fa:08 brd ff:ff:ff:ff:ff:ff
    inet 10.10.10.123/24 brd 10.10.10.255 scope global dynamic enp1s0
       valid_lft 429sec preferred_lft 429sec
    inet6 fe80::21d:97ff:feb5:fa08/64 scope link 
       valid_lft forever preferred_lft forever

Terlihat bahwa adapter yang digunakan adalah enp1s0 dengan ip dinamis 10.10.10.123 (untuk pc/server lain mungkin akan berbeda adapter dan ip-nya).

Command lain seperti
 ifconfig -a

Masuk ke netplan
 cd /etc/netplan
 
 ls
 
edit file yaml, contoh 00-installer-config.yaml
 sudo nano 00-installer-config.yaml
isinya seperti berikut ini :
 # This is the network config written by 'subiquity'
 network:
   ethernets:
     enp1s0:
       dhcp4: true
   version: 2
rubah menjadi :
 # This is the network config written by 'subiquity'
 
 network:
   version: 2
   ethernets:
     enp1s0:
       dhcp4: no
       addresses:
         - 10.10.10.9/24
       gateway4: 10.10.10.1
       nameservers:
           addresses: [8.8.8.8, 1.1.1.1]
