多云數(shù)據(jù)管理深度實踐上 | Ansible安裝OpenSDS（All in One）

隨著業(yè)務(wù)的發(fā)展數(shù)據(jù)日益見增，這些數(shù)據(jù)的可用性隨著時間的推移而下降。人們希望通過長期數(shù)字保存(LTDP)來保持持久價值的數(shù)字信息的可訪問和可用性的，以應(yīng)對過時的軟件和硬件，以及精確呈現(xiàn)內(nèi)容的這些挑戰(zhàn)。

關(guān)于多云數(shù)據(jù)管理的概念及趨勢本文不再贅述，將在另一篇文章單獨講述，本篇文章致力于技術(shù)流，那么與此同時，OpenSDS應(yīng)運而生，一個開源的多云數(shù)據(jù)管理平臺，可以同時納管本地異構(gòu)存儲，也可以完美兼容OpenStack、AWS，華為云等公有云。（https://docs.opensds.io/features/）

> dpkg -i docker-ce_18.06.1~ce~3-0~ubuntu_amd64.deb

安裝Docker-Compose

> curl -L "https://github.com/docker/compose/releases/download/1.23.1/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

> chmod +x /usr/local/bin/docker-compose

安裝golang

GitHub克隆OpenSDS

> git clone https://github.com/opensds/opensds-installer.git

> cd opensds-installer/ansible

> git checkout stable/capri

下載Ansible

> chmod +x ./install_ansible.sh && ./install_ansible.sh

> ansible --version # Ansible version 2.4.x is required.

配置OpenSDS Ansible變量

修改host_ip

cat opensds-installer/ansible/group_vars/common.yml

# This field indicates local machine host ip

host_ip: 127.0.0.1

# This field indicates which project should be deploy

# 'hotpot', 'gelato' or 'all'

deploy_project: all

配置OpenSDS lvm后端

> cat opensds-installer/ansible/group_vars/osdsdock.yml

>?

> enabled_backends: lvm

Ansible開始安裝

> ansible-playbook site.yml -i local.hosts -vvv

> ##注：安裝很慢，因為很多docker鏡像在國外，可以采用docker鏡像加速或者同步到國內(nèi)

CLI操作

> sudo cp /opt/opensds-hotpot-linux-amd64/bin/osdsctl /usr/local/bin/

>?

> 配置環(huán)境變量

> vi opensds_source.sh

> export OPENSDS_ENDPOINT=http://{your_real_host_ip}:50040

> export OPENSDS_AUTH_STRATEGY=keystone

> export OS_AUTH_URL=http://{your_real_host_ip}/identity

> export OS_USERNAME=admin

創(chuàng)建默認的塊存儲profile

osdsctl profile create '{"name": "default", "description": "default policy", "storageType": "block"}'

創(chuàng)建Volume

osdsctl volume create 1 --name=test-001

查詢Volume

osdsctl volume list

刪除Volume

osdsctl volume delete <your_volume_id>
