Belajar Linux ID – Pada tutoril kali ini kita akan mempelajari bagaimana cara membuat sebuah network baik external atau internal di openstack melalui CLI (Command line interface).
Untuk membuat network di openstack bisa menggunakan 2 cara salah satunya melaui dashboard openstack atau Horizon.
Tutorial membuat network di horizon Anda dapat merujuk pada link berikut: Openstack: Membuat Network
Berikut tahapan membuat network openstack melalui CLI:
Untuk melihat help cara membuat network di openstack gunakan perintah berikut

2
[root@hamim-controller ~(keystone_admin)]#
[root@hamim-controller ~(keystone_admin)]# openstack network --help
Cek list network yang sudah dibuat sebelumnya, bisa menggunakan perintah opentack atau neutron berikut contoh perinthnya

Untuk membuat external network Anda dapat menggunakan perintah berikut:
1
2
# neutron net-create net-ext --provider:network_type flat --provider:physical_network extnet --shared --router:external
# neutron net-create net-int1
Noted: Apabila sudah memiliki external network, maka langkah diatas bisa di skip saja.
Selanjutnya kami akan membuat internal network dengan nama network net-internal1 menggunakan perintah berikut
