Openstack IN Centos

sbr://https://blog.linuxcoding.org/artikel/install-dasar-konfigurasi-openstack-havana-rdo-centos-6-5-part-1/

Dalam OpenStack banyak pilihan network topology ataupun network system yang dapat diterapkan, pada pembahasaan ini kita akan menggunakan dasar topologi dan sistem installasi AllInOne, yang artinya semua service diinstall dan berjalan pada satu host. Dan untuk network menggunakan sistemNeutron Networking.

ISTILAH DALAM OPENSTACK :
Controller Node : Host yang menjalankan service-service OpenStack
Compute Node : Host yang menjalankan virtualisasi

SISTEM YANG AKAN DIGUNAKAN :
– Virtualisasi menggunakan KVM
– Controller Node dan Compute Node dalam satu Host

KOMPONEN OPENSTACK :
Keystone (Identity Service)
Glance (Image Service)
Cinder (Volume Service)
Neutron (Networking Services)
Nova (Compute Services)
Horizon (OpenStack Frontend)
Ceilometer (Metering Service)
Swift (Object Strage Service)
Heat (Orchestration)

DASAR TOPOLOGI OPENSTACK :

PERSIAPAN HOST CONTROLLER NETWORK TOPOLOGI :
HOST NETWORK
– 2 Pisikal NIC/Ethernet
* eth0
* eth1
HOST BRIDGE NETWORK
* br-eth1
* br-ex
* br-int

NEUTRON NETWORKING
– openvswitch
* router1
– public ip ranges
* 192.168.1.0/24
* net start 192.168.114 – 119
– private ip ranges
* 30.0.0.0/24
* net start 30.0.0.2 -254
– floating IP
* public network
– VLAN
* physnet1
* ranges 1000-2999

PERSIAPAN INSTALLASI :
OpenStack repo : http://rdo.fedorapeople.org/rdo-release.rpm
EPEL Repo : http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
Kita asumsikan CentOS 6.5 x64 telah terinstall dan masih fresh install/baru diinstall

INSTALLASI OPENSTACK HAVANA :

#yum install -y http://rdo.fedorapeople.org/rdo-release.rpm
#yum install -y http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm

#yum install -y openstack-packstack

#packstack --allinone

Installasi OpenStack selesai dan sukses, selanjutnya kita konfigurasikan Networking untuk menggunakan Neutron Networking dan vSwitch.

HAPUS DEFAULT NETWORK :

#ovs-vsctl show
17df3aee-adeb-4b1f-ba6f-3c977514ae6e
    Bridge br-ex
        Port br-ex
            Interface br-ex
                type: internal
        Port "qg-32712dd8-b7"
            Interface "qg-32712dd8-b7"
                type: internal
    Bridge br-int
        Port "qr-e3dd113d-05"
            tag: 1
            Interface "qr-e3dd113d-05"
                type: internal
        Port br-int
            Interface br-int
                type: internal
    ovs_version: "1.11.0"

#ovs-vsctl del-br br-ex
#ovs-vsctl del-br br-int
#ovs-vsctl show

KONFIGURASI NEUTRON NETWORK :
Konfigurasi Ethernet 2 (eth1)

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

Buat seperti ini :

DEVICE=eth1
BOOTPROTO=static
NM_CONTROLLED=no
ONBOOT=yes
TYPE=Ethernet

Konfigurasi Bridge dan Bridge Port Ethernet 2 (eth1):

#ovs-vsctl add-br br-int
#ifup eth1
#ovs-vsctl add-br br-eth1
#ovs-vsctl add-port br-eth1 eth1
#ovs-vsctl show

#vi /etc/sysconfig/network-scripts/ifcfg-br-ex

Buat seperti ini :

DEVICE=br-ex
BOOTPROTO=static
ONBOOT=yes
IPADDR=192.168.1.113
NETMASK=255.255.255.0
GATEWAY=192.168.1.1

Konfigurasi Ethernet 1 (eth0)

#vi /etc/sysconfig/network-scripts/ifcfg-eth0

Buat seperti ini :

DEVICE=eth0
TYPE=Ethernet
ONBOOT="yes"
NM_CONTROLLED=no
BOOTPROTO=static

Konfigurasi Bridge dan Bridge Port Ethernet 1 (eth0):

#ovs-vsctl add-br br-ex
#ovs-vsctl add-port br-ex eth0

Restart Network :

#service network restart
Shutting down interface eth0:                              [  OK  ]
Shutting down interface eth1:                              [  OK  ]
Shutting down loopback interface:                          [  OK  ]
Bringing up loopback interface:                            [  OK  ]
Bringing up interface br-ex:                               [  OK  ]
Bringing up interface eth0:                                [  OK  ]
Bringing up interface eth1:                                [  OK  ]

Melihat hasil konfigurasi :

#ovs-vsctl show
17df3aee-adeb-4b1f-ba6f-3c977514ae6e

        Port "eth1"

Oke, installasi, dasar konfigurasi network menggunakan Neutron Networking selesai. Pada pembahasan selanjutnya akan membahas bagaimana menambahkan instance/vm, menjalankan instance/vm, menambahkan floating IP pada instance/vm agar instance/vm dapat diakses dari external network.
