Attach Multiple Network Interfaces to Instance OpenStack

Dalam beberapa kasus kalian mungkin membutuhkan 2 Internal Network dalam satu Instance, dan itu memang sudah didukung dengan baik oleh OpenStack bahkan saat Instance sudah berjalan kita bisa dapat secara live menambahkan Interface baru 😀

Tapi jika ada lebih dari satu Interface dalam satu Instance, cloud-init/images tidak secara otomatis mengkonfigurasi seluruh Interface. Maka dari itu kita perlu melakukan langkah tambahan agar seluruh Interface dapat berjalan dengan semestinya:

CentOS 7
Cara Ke-1:

sudo ip addr

1: lo: &lt;LOOPBACK,UP,LOWER_UP&gt; mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1
    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: eth0: &lt;BROADCAST,MULTICAST,UP,LOWER_UP&gt; mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
    link/ether fa:16:3e:d4:31:b5 brd ff:ff:ff:ff:ff:ff
    inet 10.10.10.10/24 brd 10.99.99.255 scope global dynamic eth0
       valid_lft 60138sec preferred_lft 60138sec
    inet6 fe80::f816:3eff:fed4:31b5/64 scope link 
       valid_lft forever preferred_lft forever
3: eth1: &lt;BROADCAST,MULTICAST&gt; mtu 1500 qdisc noop state DOWN group default qlen 1000
    link/ether fa:16:3e:f2:65:4a brd ff:ff:ff:ff:ff:ff

sudo ip addr

Buat berkas Konfigurasi eth1

sudo cp -v /etc/sysconfig/network-scripts/ifcfg-eth0 /etc/sysconfig/network-scripts/ifcfg-eth1

1	sudo cp -v /etc/sysconfig/network-scripts/ifcfg-eth0 /etc/sysconfig/network-scripts/ifcfg-eth1

Sesuaikan Device dan HWADDR

sudo vi /etc/sysconfig/network-scripts/ifcfg-eth1

BOOTPROTO=dhcp
DEVICE=eth1
HWADDR=fa:16:3e:f2:65:4a
ONBOOT=yes
TYPE=Ethernet

DEFROUTE=no

sudo vi /etc/sysconfig/network-scripts/ifcfg-eth1

BOOTPROTO=dhcp

DEVICE=eth1

HWADDR=fa:16:3e:f2:65:4a

ONBOOT=yes

TYPE=Ethernet

USERCTL=no

DEFROUTE=no

Bring up eth1

sudo ifup eth1

1	sudo ifup eth1

Verifikasi

Cara Ke-2:
Dengan menambahkan Configuration > Customisation Script berikut pada saat membuat Instance baru dengan Multiple Interface:

#!/bin/bash
sudo -i
echo "dhclient" >> /etc/rc.local
chmod +x /etc/rc.local
/etc/rc.local

#!/bin/bash

sudo -i

echo "dhclient" >> /etc/rc.local

chmod +x /etc/rc.local

/etc/rc.local

Ubuntu 16.04

vim K99multinic.sh

1	vim K99multinic.sh

#!/bin/bash
hname=$(hostname)
cat /etc/hosts | grep $hname >> /dev/null
if [ $? -ne 0 ];then
 sudo bash -c "echo '127.0.0.1 $hname' >> /etc/hosts"
fi
netfile=$(find /etc/network/interfaces.d -name "*.cfg")
for interface in $(ls -1 /sys/class/net | grep ens) ;do
   cat $netfile | grep $interface >> /dev/null
   if [ $? -ne 0 ];then
     sudo bash -c "echo 'auto $interface' >> ${netfile}"
     sudo bash -c "echo 'iface $interface inet dhcp' >> ${netfile}"
     sudo ifup $interface
  fi
done

#!/bin/bash

hname=$(hostname)

cat /etc/hosts | grep $hname >> /dev/null

if [ $? -ne 0 ];then

sudo bash -c "echo '127.0.0.1 $hname' >> /etc/hosts"

netfile=$(find /etc/network/interfaces.d -name "*.cfg")

for interface in $(ls -1 /sys/class/net | grep ens) ;do

cat $netfile | grep $interface >> /dev/null

if [ $? -ne 0 ];then

sudo bash -c "echo 'auto $interface' >> ${netfile}"

sudo bash -c "echo 'iface $interface inet dhcp' >> ${netfile}"

sudo ifup $interface

done

Ubah permission dan Eksekusi skrip

chmod +x K99multinic.sh
./K99multinic.sh

1 2	chmod +x K99multinic.sh ./K99multinic.sh

Ubah kepemilikan lalu simpan ke /etc/rc0.d/ agar skrip dieksekusi saat reboot

sudo chown root:root K99multinic.sh
sudo mv K99multinic.sh /etc/rc0.d/

1 2	sudo chown root:root K99multinic.sh sudo mv K99multinic.sh /etc/rc0.d/

Ujicoba reboot Instance

sudo reboot

1	sudo reboot

Sekian dan Selamat Liburan. 🙂

Membuat Instance OpenStack dengan Fixed IP

Linux, OpenStack
fixed ip, neutron, nova, OpenStack, port, static
Leave a comment

Terkadang kita mungkin memiliki kebutuhan untuk membuat sebuah instance dengan fixed IP (~~statis~~) tertentu. Untuk melakukan ini kita harus membuat secara manual port neutron. panduan ini bisa dilakukan untuk network External atau Internal

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.
