Tambahkan host komputasi

Gunakan prosedur berikut untuk menambahkan host komputasi ke cluster operasional.

  1. Configure the host as a target host. See the target hosts configuration section of the deploy guide for more information.

  2. Edit file /etc/openstack_deploy/openstack_user_config.yml dan tambahkan host ke bait (stanza) compute_hosts.

    Jika perlu, ubah juga bait (stanza) used_ips.

  3. Jika cluster menggunakan Telemetry/Metering (ceilometer), edit file /etc/openstack_deploy/conf.d/ceilometer.yml dan tambahkan host ke stanza metering-compute_hosts.

  4. Jalankan perintah berikut untuk menambahkan host. Ganti NEW_HOST_NAME dengan nama host baru.

    # cd /opt/openstack-ansible/playbooks
# openstack-ansible openstack.osa.setup_hosts --limit localhost,NEW_HOST_NAME
# openstack-ansible openstack.osa.openstack_hosts_setup -e openstack_hosts_group=nova_compute --tags openstack_hosts-file
# openstack-ansible openstack.osa.setup_openstack --limit localhost,NEW_HOST_NAME

    Atau Anda dapat mencoba menggunakan skrip penyebaran node komputasi baru /opt/openstack-ansible/scripts/add-compute.sh.

    You can provide this script with extra tasks that will be executed before or right after OpenStack-Ansible roles. To do so you should set environment variables PRE_OSA_TASKS or POST_OSA_TASKS with plays to run devided with semicolon:

    # export POST_OSA_TASKS="/opt/custom/setup.yml --limit HOST_NAME;/opt/custom/tasks.yml --tags deploy"
# /opt/openstack-ansible/scripts/add-compute.sh HOST_NAME,HOST_NAME_2

Uji node komputasi baru

After creating a new node, test that the node runs correctly by launching an instance on the new node:

$ openstack server create --image IMAGE --flavor m1.tiny \
--key-name KEY --availability-zone ZONE:HOST:NODE \
--nic net-id=UUID SERVER

Pastikan instance baru dapat menanggapi tes koneksi jaringan melalui perintah ping. Masuk ke sistem pemantauan Anda, dan verifikasi bahwa monitor mengembalikan sinyal hijau untuk simpul node.
