Konfigurasi DHCP Server di AlmaLinux

Konfigurasi DHCP Server

1. Install dan Konfigurasi DHCP Server di AlmaLinux

a. Install dhcp-server

$ sudo dnf install dhcp-server -y

b. Tentukan interface NA

Edit file:

$ sudo vim /etc/sysconfig/dhcpd

DHCPDARGS=enp0s8

c. Konfigurasi DHCP

Edit file konfigurasi utama:

$ sudo vim /etc/dhcp/dhcpd.conf

subnet 10.10.40.0 netmask 255.255.255.0 {
  range 10.10.40.5 11.11.21.100;
  option routers 10.10.40.1;
  option domain-name-servers 8.8.8.8, 8.8.4.4;
}

d. Atur IP statis di interface Internal (NA)

Edit dengan nmtui pilih interface enp0s8 lalu isi manual IPv4:

IP Address: 10.10.40.1

Restart network:

$ sudo systemctl restart NetworkManager

e. Jalankan DHCP Server

$ sudo systemctl enable dhcpd
$ sudo systemctl start dhcpd

2. Alpine Linux sebagai DHCP Client

Edit /etc/network/interfaces:

# vi /etc/network/interfaces

auto eth0
iface eth0 inet dhcp

# /etc/init.d/networking restart

3. Tes Koneksi dari Alpine

ip a                # Pastikan mendapat IP dari range 10.10.40.x
ping 10.10.40.1     # Ping ke AlmaLinux (gateway)
ping 8.8.8.8        # Uji koneksi internet jika ada NAT
