在compute节点中启动服务

[root@compute ~]# systemctl restart openstack-nova-compute.service
Job for openstack-nova-compute.service failed because the control process exited with error code.\
 See "systemctl status openstack-nova-compute.service" and "journalctl -xe" for details.

发现是身份验证的问题，关闭controller节点和自身防火墙后，问题没有解决。

compute节点重启libvirtd.service，openstack-nova-compute.service，libvirt.service正常，但openstack-nova-compute.service仍然无法启动。

查找controller节点 输入netstat -tnlup 发现25672和5672端口正常，rabbitmq服务正常开启

查看rabbitmq日志（/var/log/rabbitmq/rabbit@controller.log ）

 结果显示用户openstack拥有无效凭证。

解决方案如下：

[root@controller ~]# rabbitmqctl list_users
Listing users
openstack       []
guest   [administrator]
root    []
##查看是否有openstack用户，如果有

##输入rabbitmqctl -q delete_user openstack 删除

##重新设置openstack用户

[root@controller ~]# rabbitmqctl add_user openstack RABBIT_PASS

##这里的“openstack”就是用户名，“RABBIT_PASS”是该用户密码。实际工作中可以按照需##要进行更改。

##设置用户权限

[root@controller ~]# rabbitmqctl set_permissions openstack ".*" ".*" ".*"

##查看用户权限

[root@controller ~]# rabbitmqctl list_user_permissions openstack

[root@controller ~]# rabbitmqctl list_users

Listing users

openstack []

##重启rabbitmq

[root@controller rabbitmq]# systemctl restart rabbitmq-server.service

 再次查看日志/var/log/rabbitmq/rabbit@controller.log

 然后重启compute节点 openstack-nova-compute.service服务

systemctl restart openstack-nova-compute.service

 正常启动

命令 ps aux|grep nova 查看 nova-compute服务 

 问题解决。。
