Luncurkan sebuah instance pada jaringan self-service¶
Tentukan opsi instance¶
Untuk memulai sebuah instance, Anda harus setidaknya menentukan flavor, nama image, jaringan, security group, key, dan nama instance.
Pada ‘controller node’, dapatkan source kredensial demo untuk mendapatkan akses ke command CLI user-only:
$ . demo-openrcRasa menentukan profil alokasi sumber daya virtual yang meliputi prosesor, memori, dan penyimpanan (storage).
Lihat daftar flavor yang tersedia:
$ openstack flavor list +----+-----------+-------+------+-----------+-------+-----------+ | ID | Name | RAM | Disk | Ephemeral | VCPUs | Is Public | +----+-----------+-------+------+-----------+-------+-----------+ | 1 | m1.tiny | 512 | 1 | 0 | 1 | True | | 2 | m1.small | 2048 | 20 | 0 | 1 | True | | 3 | m1.medium | 4096 | 40 | 0 | 2 | True | | 4 | m1.large | 8192 | 80 | 0 | 4 | True | | 5 | m1.xlarge | 16384 | 160 | 0 | 8 | True | +----+-----------+-------+------+-----------+-------+-----------+
Instance ini menggunakan flavor m1.tiny. Jika Anda menciptakan opsi flavor m1.nano, menggunakannya sebagai pengganti flavor m1.tiny.
Catatan
Anda juga dapat referensi flavor dengan ID.
Lihat daftar image yang tersedia:
$ openstack image list +--------------------------------------+--------+--------+ | ID | Name | Status | +--------------------------------------+--------+--------+ | 390eb5f7-8d49-41ec-95b7-68c0d5d54b34 | cirros | active | +--------------------------------------+--------+--------+
Instance ini menggunakan image cirros.
Lihat daftar jaringan yang tersedia:
$ openstack network list +--------------------------------------+-------------+--------------------------------------+ | ID | Name | Subnets | +--------------------------------------+-------------+--------------------------------------+ | 4716ddfe-6e60-40e7-b2a8-42e57bf3c31c | selfservice | 2112d5eb-f9d6-45fd-906e-7cabd38b7c7c | | b5b6993c-ddf9-40e7-91d0-86806a42edb8 | provider | 310911f6-acf0-4a47-824e-3032916582ff | +--------------------------------------+-------------+--------------------------------------+
Instance ini menggunakan jaringan self-service selfservice. Namun, Anda harus referensi jaringan ini menggunakan ID bukan nama.
Lihat daftar kelompok keamanan (security group) yang tersedia:
$ openstack security group list +--------------------------------------+---------+------------------------+ | ID | Name | Description | +--------------------------------------+---------+------------------------+ | dd2b614c-3dad-48ed-958b-b155a3b38515 | default | Default security group | +--------------------------------------+---------+------------------------+
Instance ini menggunakan security group default.
Luncur instance
Ganti SELFSERVICE_NET_ID dengan ID dari jaringan selfservice.
$ openstack server create --flavor m1.tiny --image cirros \ --nic net-id=SELFSERVICE_NET_ID --security-group default \ --key-name mykey selfservice-instance +--------------------------------------+---------------------------------------+ | Field | Value | +--------------------------------------+---------------------------------------+ | OS-DCF:diskConfig | MANUAL | | OS-EXT-AZ:availability_zone | | | OS-EXT-STS:power_state | 0 | | OS-EXT-STS:task_state | scheduling | | OS-EXT-STS:vm_state | building | | OS-SRV-USG:launched_at | None | | OS-SRV-USG:terminated_at | None | | accessIPv4 | | | accessIPv6 | | | addresses | | | adminPass | 7KTBYHSjEz7E | | config_drive | | | created | 2016-02-26T14:52:37Z | | flavor | m1.tiny (1) | | hostId | | | id | 113c5892-e58e-4093-88c7-e33f502eaaa4 | | image | cirros (390eb5f7-8d49-41ec-95b7-68c0d | | | 5d54b34) | | key_name | mykey | | name | selfservice-instance | | os-extended-volumes:volumes_attached | [] | | progress | 0 | | project_id | ed0b60bf607743088218b0a533d5943f | | properties | | | security_groups | [{u'name': u'default'}] | | status | BUILD | | updated | 2016-02-26T14:52:38Z | | user_id | 58126687cbcc4888bfa9ab73a2256f27 | +--------------------------------------+---------------------------------------+
Periksa status instance Anda:
$ openstack server list +--------------------------------------+----------------------+--------+---------------------------------+ | ID | Name | Status | Networks | +--------------------------------------+----------------------+--------+---------------------------------+ | 113c5892-e58e-4093-88c7-e33f502eaaa4 | selfservice-instance | ACTIVE | selfservice=172.16.1.3 | | 181c52ba-aebc-4c32-a97d-2e8e82e4eaaf | provider-instance | ACTIVE | provider=203.0.113.103 | +--------------------------------------+----------------------+--------+---------------------------------+
Status perubahan dari BUILD ke ACTIVE ketika proses pembangunan berhasil selesai.
Akses instance menggunakan konsol virtual¶
Dapatkan Virtual Network Computing (VNC) URL sesi instance Anda dan mengaksesnya dari web browser:
$ openstack console url show selfservice-instance +-------+---------------------------------------------------------------------------------+ | Field | Value | +-------+---------------------------------------------------------------------------------+ | type | novnc | | url | http://controller:6080/vnc_auto.html?token=5eeccb47-525c-4918-ac2a-3ad1e9f1f493 | +-------+---------------------------------------------------------------------------------+
Catatan
Jika web browser Anda berjalan pada host yang tidak dapat resolve controller host name, Anda dapat mengganti controller dengan alamat IP dari interface manajemen pada ‘controller node’ Anda.
Image CirrOS termasuk nama user / sandi otentikasi konvensional dan memberikan mandat ini pada prompt login. Setelah masuk ke CirrOS, kami sarankan Anda memverifikasi konektivitas jaringan menggunakan ping.
Verifikasi akses ke gateway jaringan self-service:
$ ping -c 4 172.16.1.1 PING 172.16.1.1 (172.16.1.1) 56(84) bytes of data. 64 bytes from 172.16.1.1: icmp_req=1 ttl=64 time=0.357 ms 64 bytes from 172.16.1.1: icmp_req=2 ttl=64 time=0.473 ms 64 bytes from 172.16.1.1: icmp_req=3 ttl=64 time=0.504 ms 64 bytes from 172.16.1.1: icmp_req=4 ttl=64 time=0.470 ms --- 172.16.1.1 ping statistics --- 4 packets transmitted, 4 received, 0% packet loss, time 2998ms rtt min/avg/max/mdev = 0.357/0.451/0.504/0.055 ms
Verifikasi akses ke internet:
$ ping -c 4 openstack.org PING openstack.org (174.143.194.225) 56(84) bytes of data. 64 bytes from 174.143.194.225: icmp_req=1 ttl=53 time=17.4 ms 64 bytes from 174.143.194.225: icmp_req=2 ttl=53 time=17.5 ms 64 bytes from 174.143.194.225: icmp_req=3 ttl=53 time=17.7 ms 64 bytes from 174.143.194.225: icmp_req=4 ttl=53 time=17.5 ms --- openstack.org ping statistics --- 4 packets transmitted, 4 received, 0% packet loss, time 3003ms rtt min/avg/max/mdev = 17.431/17.575/17.734/0.143 ms
Akses instance jarak jauh (remote)¶
Buat floating IP address pada jaringan virtual provider:
$ openstack ip floating create provider +-------------+--------------------------------------+ | Field | Value | +-------------+--------------------------------------+ | fixed_ip | None | | id | 3d05a9b1-b1af-4884-be1c-833a69744449 | | instance_id | None | | ip | 203.0.113.104 | | pool | provider | +-------------+--------------------------------------+
Lakukan asosiasi alamat IP mengambang (floating IP address) dengan instance:
$ openstack ip floating add 203.0.113.104 selfservice-instance
Catatan
Command ini tidak memberikan output.
Periksa status alamat IP mengambang (floating IP address) Anda:
$ openstack server list +--------------------------------------+----------------------+--------+---------------------------------------+ | ID | Name | Status | Networks | +--------------------------------------+----------------------+--------+---------------------------------------+ | 113c5892-e58e-4093-88c7-e33f502eaaa4 | selfservice-instance | ACTIVE | selfservice=172.16.1.3, 203.0.113.104 | | 181c52ba-aebc-4c32-a97d-2e8e82e4eaaf | provider-instance | ACTIVE | provider=203.0.113.103 | +--------------------------------------+----------------------+--------+---------------------------------------+
Verifikasi konektivitas untuk instance melalui floating IP address dari ‘controller node’ atau semua host pada jaringan fisik provider:
$ ping -c 4 203.0.113.104 PING 203.0.113.104 (203.0.113.104) 56(84) bytes of data. 64 bytes from 203.0.113.104: icmp_req=1 ttl=63 time=3.18 ms 64 bytes from 203.0.113.104: icmp_req=2 ttl=63 time=0.981 ms 64 bytes from 203.0.113.104: icmp_req=3 ttl=63 time=1.06 ms 64 bytes from 203.0.113.104: icmp_req=4 ttl=63 time=0.929 ms --- 203.0.113.104 ping statistics --- 4 packets transmitted, 4 received, 0% packet loss, time 3002ms rtt min/avg/max/mdev = 0.929/1.539/3.183/0.951 ms
Akses instance Anda menggunakan SSH dari controller node atau semua host pada jaringan fisik provider:
$ ssh cirros@203.0.113.104 The authenticity of host '203.0.113.104 (203.0.113.104)' can't be established. RSA key fingerprint is ed:05:e9:e7:52:a0:ff:83:68:94:c7:d1:f2:f8:e2:e9. Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added '203.0.113.104' (RSA) to the list of known hosts. $
Jika instance Anda tidak memulai atau tampaknya bekerja seperti yang Anda harapkan, lihat bagian Instance Boot Failures di OpenStack Operations Guide untuk informasi lebih lanjut atau menggunakan salah satu many other options untuk mencari bantuan. Kami ingin instalasi pertama Anda untuk bekerja!
