标签：用户   tac   com   for   usr   perm   blog   失败   openstack   

问题描述

运行

systemctl restart openstack-nova-scheduler.service

失败，查看日志报错如下：

2019-12-22 14:52:27.426 15138 ERROR oslo_service.service     (class_id, method_id), ConnectionError)
2019-12-22 14:52:27.426 15138 ERROR oslo_service.service AccessRefused: (0, 0): (403) ACCESS_REFUSED - Login was refused using authentication mechanism AMQPLAIN. For details see the broker logfile.

查看状态

[root@controller ~]# systemctl status openstack-nova-scheduler.service
● openstack-nova-scheduler.service - OpenStack Nova Scheduler Server
   Loaded: loaded (/usr/lib/systemd/system/openstack-nova-scheduler.service; enabled; vendor preset: disabled)

解决

原因是没有创建openstack用户（但是我之前确实创建了。。。重新启动加了一块网卡就没了），重新创建该用户，解决问题。
参考

// 查看当前rabbitmq的用户
rabbitmqctl list_users
// 添加openstack用户
rabbitmqctl add_user openstack 123456
//分配权限
rabbitmqctl set_permissions openstack ".*" ".*" ".*"
