适用于 Red Hat Enterprise Linux 和 CentOS 的安装和配置¶
本节描述了如何在 Red Hat Enterprise Linux 9 和 CentOS Stream 9 上安装和配置数据库服务。
先决条件¶
在安装和配置数据库服务之前，您必须创建一个数据库、服务凭证和 API 端点。
要创建数据库，请完成以下步骤
使用数据库访问客户端以
root用户身份连接到数据库服务器$ mysql -u root -p
创建
trove数据库CREATE DATABASE trove;授予对
trove数据库的适当访问权限GRANT ALL PRIVILEGES ON trove.* TO 'trove'@'localhost' \ IDENTIFIED BY 'TROVE_DBPASS'; GRANT ALL PRIVILEGES ON trove.* TO 'trove'@'%' \ IDENTIFIED BY 'TROVE_DBPASS';
将
TROVE_DBPASS替换为合适的密码。退出数据库访问客户端。
激活
admin凭证以访问仅管理员可用的 CLI 命令$ . admin-openrc
要创建服务凭证，请完成以下步骤
创建
trove用户$ openstack user create --domain default --password-prompt trove User Password: Repeat User Password: +-----------+-----------------------------------+ | Field | Value | +-----------+-----------------------------------+ | domain_id | default | | enabled | True | | id | ca2e175b851943349be29a328cc5e360 | | name | trove | +-----------+-----------------------------------+
将
admin角色添加到trove用户$ openstack role add --project service --user trove admin
注意
此命令不会产生任何输出。
创建
trove服务实体$ openstack service create --name trove \ --description "Database" database +-------------+-----------------------------------+ | Field | Value | +-------------+-----------------------------------+ | description | Database | | enabled | True | | id | 727841c6f5df4773baa4e8a5ae7d72eb | | name | trove | | type | database | +-------------+-----------------------------------+
创建数据库服务 API 端点
$ openstack endpoint create --region RegionOne \ database public http://controller:8779/v1.0/%\(tenant_id\)s +--------------+----------------------------------------------+ | Field | Value | +--------------+----------------------------------------------+ | enabled | True | | id | 3f4dab34624e4be7b000265f25049609 | | interface | public | | region | RegionOne | | region_id | RegionOne | | service_id | 727841c6f5df4773baa4e8a5ae7d72eb | | service_name | trove | | service_type | database | | url | http://controller:8779/v1.0/%\(tenant_id\)s | +--------------+----------------------------------------------+ $ openstack endpoint create --region RegionOne \ database internal http://controller:8779/v1.0/%\(tenant_id\)s +--------------+----------------------------------------------+ | Field | Value | +--------------+----------------------------------------------+ | enabled | True | | id | 9489f78e958e45cc85570fec7e836d98 | | interface | internal | | region | RegionOne | | region_id | RegionOne | | service_id | 727841c6f5df4773baa4e8a5ae7d72eb | | service_name | trove | | service_type | database | | url | http://controller:8779/v1.0/%\(tenant_id\)s | +--------------+----------------------------------------------+ $ openstack endpoint create --region RegionOne \ database admin http://controller:8779/v1.0/%\(tenant_id\)s +--------------+----------------------------------------------+ | Field | Value | +--------------+----------------------------------------------+ | enabled | True | | id | 76091559514b40c6b7b38dde790efe99 | | interface | admin | | region | RegionOne | | region_id | RegionOne | | service_id | 727841c6f5df4773baa4e8a5ae7d72eb | | service_name | trove | | service_type | database | | url | http://controller:8779/v1.0/%\(tenant_id\)s | +--------------+----------------------------------------------+
安装和配置组件¶
安装软件包
# dnf install openstack-trove python3-troveclient
在
/etc/trove目录中，编辑trove.conf文件，这里是一个示例[DEFAULT] network_driver = trove.network.neutron.NeutronDriver management_networks = ef7541ad-9599-4285-878a-e0ab62032b03 management_security_groups = d0d797f7-11d4-436e-89a3-ac8bca829f81 cinder_volume_type = lvmdriver-1 nova_keypair = trove-mgmt default_datastore = mysql taskmanager_manager = trove.taskmanager.manager.Manager trove_api_workers = 5 transport_url = rabbit://stackrabbit:password@192.168.1.34:5672/ control_exchange = trove reboot_time_out = 300 usage_timeout = 900 agent_call_high_timeout = 1200 use_syslog = False debug = True [keystone_authtoken] memcached_servers = localhost:11211 cafile = /devstack/stack/data/ca-bundle.pem project_domain_name = Default project_name = service user_domain_name = Default password = password username = trove auth_url = http://192.168.1.34/identity auth_type = password [service_credentials] auth_url = http://192.168.1.34/identity/v3 region_name = RegionOne project_name = service password = password project_domain_name = Default user_domain_name = Default username = trove [database] connection = mysql+pymysql://root:password@127.0.0.1/trove?charset=utf8 [mariadb] tcp_ports = 3306,4444,4567,4568 [mysql] tcp_ports = 3306 [postgresql] tcp_ports = 5432
验证
api-paste.ini文件是否存在于/etc/trove中。如果文件不存在，您可以从 此处 获取它。
编辑
/etc/trove/trove-guestagent.conf文件，以便未来的 trove 客户机可以连接到您的 OpenStack 环境，这里是一个示例[DEFAULT] log_file = trove-guestagent.log log_dir = /var/log/trove/ ignore_users = os_admin control_exchange = trove transport_url = rabbit://stackrabbit:password@172.24.5.1:5672/ command_process_timeout = 60 use_syslog = False debug = True [service_credentials] auth_url = http://192.168.1.34/identity/v3 region_name = RegionOne project_name = service password = password project_domain_name = Default user_domain_name = Default username = trove
填充您之前在本过程中创建的 trove 数据库
# su -s /bin/sh -c "trove-manage db_sync" trove ... 2016-04-06 22:00:17.771 10706 INFO trove.db.sqlalchemy.migration [-] Upgrading mysql+pymysql://trove:dbaasdb@controller/trove to version latest
注意
忽略此输出中的任何弃用消息。
完成安装¶
启动数据库服务并配置它们在系统启动时启动
# systemctl enable openstack-trove-api.service \
openstack-trove-taskmanager.service \
openstack-trove-conductor.service
# systemctl start openstack-trove-api.service \
openstack-trove-taskmanager.service \
openstack-trove-conductor.service
