红帽全球峰会6.8. 升级遥测(ceilometer)
此流程同时升级所有 Controller 节点上的 Telemetry 服务的软件包。
停止 Pacemaker 中的所有 Telemetry 资源：
# pcs resource disable openstack-ceilometer-central # pcs resource disable openstack-ceilometer-api-clone # pcs resource disable openstack-ceilometer-alarm-evaluator-clone # pcs resource disable openstack-ceilometer-collector-clone # pcs resource disable openstack-ceilometer-notification-clone # pcs resource disable openstack-ceilometer-alarm-notifier-clone # pcs resource disable delay-clone-
等待
pcs status的输出显示上述服务已停止运行。 升级相关软件包：
# yum upgrade 'openstack-ceilometer*' 'python-ceilometer*'重新载入
systemd以考虑更新的单元文件：# systemctl daemon-reload使用以下命令更新 Telemetry 数据库模式。
# ceilometer-dbsync使用 Pacemaker 清理 Telemetry 服务：
# pcs resource cleanup delay-clone # pcs resource cleanup openstack-ceilometer-alarm-notifier-clone # pcs resource cleanup openstack-ceilometer-notification-clone # pcs resource cleanup openstack-ceilometer-collector-clone # pcs resource cleanup openstack-ceilometer-alarm-evaluator-clone # pcs resource cleanup openstack-ceilometer-api-clone # pcs resource cleanup openstack-ceilometer-central在 Pacemaker 中重启所有 Telemetry 资源：
# pcs resource enable delay-clone # pcs resource enable openstack-ceilometer-alarm-notifier-clone # pcs resource enable openstack-ceilometer-notification-clone # pcs resource enable openstack-ceilometer-collector-clone # pcs resource enable openstack-ceilometer-alarm-evaluator-clone # pcs resource enable openstack-ceilometer-api-clone # pcs resource enable openstack-ceilometer-central-
等待
pcs status的输出显示上述资源正在运行。
重要
之前版本的 Telemetry 服务使用 rpc_backend 参数的值，该参数现已弃用。检查 /etc/ceilometer/ceilometer.conf 文件中的 rpc_backend 参数是否已设置为以下内容：
rpc_backend=rabbit
