trove mitaka集成

本文介绍ubuntun 14.04 LTS 下openstack trove集成安装的步骤及配置。

1. 安装

1.1 配置apt源：

echo “debhttp://ubuntu-cloud.archive.canonical.com/ubuntu/ trusty-updates/mitaka main”>/etc/apt/mitaka.list

apt-get -y installubuntu-cloud-keyring

apt-get update

1.2 创建trove数据库

登录到安装后端数据库的管理节点上，一般的生产环境中可能会部署在controller节点上，并且mysql本身是以HA方式部署的，因此登录到任意一台包含DB的节点上，进行如下操作即可。

mysql–u root –p；

CREATEDATABASE trove；

GRANTALL PRIVILEGES ON trove.* TO 'trove'@'localhost' IDENTIFIED BY 'TROVE_DBPASS'；

GRANTALL PRIVILEGES ON trove.* TO 'trove'@'%' IDENTIFIED BY 'TROVE_DBPASS'；

替换TROVE_DBPASS为合适的密码；

1.3 创建trove service

bash运行openstack租户环境变量管理员用户脚本（admin.rc）,包含类似如下内容：

OS_AUTH_KEY=”openstack”

OS_AUTH_URL=”http://localhost:5000/v2.0/”

OS_PASSWORD=”admin_pass”

OS_TENANT_NAME=”admin”

OS_USERNAME=”admin”

然后运行如下命令：

openstackuser create --domainlocal –password TROVE_PASS trove （替换local和TROVE_PASS 为环境相应的值）
openstackservice create --name trove --description "Database" database
openstack endpoint create --region nova database public https://controller:8779/v1.0/%\(tenant_id\)s
openstack endpoint create --region nova database adminhttp://controller:8779/v1.0/%\(tenant_id\)s
openstack endpoint create --region nova database internalhttp://controller:8779/v1.0/%\(tenant_id\)s

（替换nova和controller为环境中正确的region值和IP，一般情况下，生产环境中都会在前端做负载，因此controller 的IP一般为一个VIP，可通过openstack catalog list查看其它服务的service IP查看）

1.4 安装trove

在controller节点上执行：

apt-get install python-pexpect sqlite3 （注意：在执行该命令时，ubuntu官方源并不能完全安装，需要安装其它的源，比如163源，安装完毕后，需要去掉该源，以避免后续的trove安装）

apt-getinstall python-trove trove-common trove-api trove-taskmanager trove-conductor

1.5 安装dashboard

pipinstall trove-dashboard==7.0.0.0b2

cp /usr/local/lib/python2.7/dist-packages/trove_dashboard/enabled/_[0-9]*.py*

/usr/share/openstack-dashboard/openstack_dashboard/local/enabled/

service apache2 restart

2.配置
