Membuat Instance OpenStack dengan IP Statis

Linux, OpenStack

Leave a comment

Terkadang kita mungkin memiliki kebutuhan untuk membuat sebuah instance dengan alamat IP statis tertentu (Fixed IP). Untuk melakukan ini kita harus membuat secara manual port neutron

BUI (Browser User Interface)

1. Masuk Panel Admin > Networks > Ports > Klik Network External > Ports

2. Klik +Create Port lalu isi kan bagian yang dibutuhkan sebagai berikut:

3. Membuat Instance seperti biasa, hanya saja pada tab Networks di lewat atau di Unselect gunakan Network Ports yang sudah kita buat tadi

4. Verifikasi Instance sudah berjalan dengan IP statis yang sudah kita buat tadi

CLI (Command Line Interface)

Jika kalian lebih terbiasa menggunakan CLI, berikut caranya:

neutron port-create --fixed-ip subnet_id=SUBNET_ID,ip_address=IP_FROM_POOL --name PORT_NAME NETWORK_ID

1	neutron port-create --fixed-ip subnet_id=SUBNET_ID,ip_address=IP_FROM_POOL --name PORT_NAME NETWORK_ID

Pasang VirtualBMC (IPMI) untuk Lab TripleO

Linux, OpenStack
IPMI, OpenStack, openSUSE, TripleO, VBMC
Leave a comment

Sebenarnya ada beberapa cara untuk memasang VirtualBMC cara termudah ialah menggunakan pip install atau bisa juga pasang manual langsung dari sumbernya di git.

Hypervisor
openSUSE 42.3 + KVM (10.2.2.1)

Pasang python-pip dan virtualbmc

zypper in python-pip gcc python-devel libvirt-devel
pip install --upgrade pip
pip search virtualbmc
pip install virtualbmc

zypper in python-pip gcc python-devel libvirt-devel

pip install --upgrade pip

pip search virtualbmc

pip install virtualbmc

Periksa nama VM overcloud yang akan di kontrol oleh VM undercloud dengan perintah IPMI

host:~ # virsh list --all |grep ooo
 67    ooo-uc                         running
 -     ooo-srv0                       shut off
 -     ooo-srv1                       shut off
 -     ooo-srv2                       shut off
 -     ooo-srv3                       shut off

host:~ # virsh list --all |grep ooo

67 ooo-uc running

- ooo-srv0 shut off

- ooo-srv1 shut off

- ooo-srv2 shut off

- ooo-srv3 shut off

Tambahkan vbmc ke VM, defaultnya IPMI menggunakan port 623, kalian juga bisa menggunakan opsi -p/–port jika ingin menggunakan port yang berbeda

vbmc add ooo-srv0 --username admin --password rahasia --port 623
vbmc add ooo-srv1 --username admin --password rahasia --port 624
vbmc add ooo-srv2 --username admin --password rahasia --port 625
vbmc add ooo-srv3 --username admin --password rahasia --port 626

vbmc add ooo-srv0 --username admin --password rahasia --port 623

vbmc add ooo-srv1 --username admin --password rahasia --port 624

vbmc add ooo-srv2 --username admin --password rahasia --port 625

vbmc add ooo-srv3 --username admin --password rahasia --port 626

Jalankan vbmc di host

vbmc start ooo-srv0
vbmc start ooo-srv1
vbmc start ooo-srv2
vbmc start ooo-srv3

vbmc start ooo-srv0

vbmc start ooo-srv1

vbmc start ooo-srv2

vbmc start ooo-srv3

Verifikasi, pastikan statusnya running

host:~ # vbmc list
+-------------+---------+---------+------+
| Domain name |  Status | Address | Port |
+-------------+---------+---------+------+
|   ooo-srv0  | running |    ::   | 623  |
|   ooo-srv1  | running |    ::   | 624  |
|   ooo-srv2  | running |    ::   | 625  |
|   ooo-srv3  | running |    ::   | 626  |
+-------------+---------+---------+------+

host:~ # vbmc list

+-------------+---------+---------+------+

+-------------+---------+---------+------+

| ooo-srv0 | running | :: | 623 |

| ooo-srv1 | running | :: | 624 |

| ooo-srv2 | running | :: | 625 |

| ooo-srv3 | running | :: | 626 |

+-------------+---------+---------+------+

VM Undercloud
Cek konektifias ke node overcloud menggunakan perintah ipmitool:

[stack@undercloud ~]$ ipmitool -I lanplus -U admin -P rahasia -H [ip-host] power status -p 623
Chassis Power is off

1 2	[stack@undercloud ~]$ ipmitool -I lanplus -U admin -P rahasia -H [ip-host] power status -p 623 Chassis Power is off

TripleO
Register node overcloud di UI TripleO

Lalu masukan NIC MAC Addresses dibagian bawah dan klik Register Nodes.

Troubleshooting:
1. Error: Unable to establish IPMI v2 / RMCP+ session
Pastikan port yang dipakai di vbmc di allow di firewall

sudo firewall-cmd --permanent --zone=public --add-port=623-626/udp
sudo firewall-cmd --reload

1 2	sudo firewall-cmd --permanent --zone=public --add-port=623-626/udp sudo firewall-cmd --reload

2. Exception TypeError: “‘NoneType’ object is not callable” in ignored
Error ini bisa diabaikan saja.

Konfigurasi VLAN Tagging dengan IP Command

Membuat VLAN tagging di interface virbr1 dengan nama dan ID VLAN 100

ip link add link virbr1 name virbr1.100 type vlan id 100
ip link set dev virbr1.100 up

1 2	ip link add link virbr1 name virbr1.100 type vlan id 100 ip link set dev virbr1.100 up
