解决openstack-nova-compute.service无法启动问题_job for openstack-nova-compute.service failed beca

1.启动服务

[root@computer ~]# 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.

2.查看compute节点上的nova-compute.log日志文件，发现身份验证机制AMQPLAIN拒绝登录。

[root@computer ~]# tail /var/log/nova/nova-compute.log

3.关闭防火墙

[root@controller ~]# systemctl  stop  firewalld
[root@controller ~]# systemctl  disable  firewalld

4.在compute节点上，重启libvirtd.service，openstack-nova-compute.service。发现libvirtd.service正常启动，openstack-nova-compute.service仍然无法启动。

[root@computer ~]# systemctl  start  libvirtd.service 
[root@computer ~]# systemctl  status  libvirtd.service

[root@computer ~]# systemctl restart openstack-nova-compute.service

5.返回到controller节点，核查rabbitmq服务是否开启，5672端口是否打开，结果显示都是正常打开。

[root@controller ~]# ps -ef|grep rabbitmq
rabbitmq  12372      1  1 17:01 ?        00:00:19 /usr/lib64/erlang/erts-8.3.5.3/bin/beam.smp -W w -A 64 -P 1048576 -t 5000000 -stbt db -zdbbl 128000 -K true -- -root /usr/lib64/erlang -progname erl -- -home /var/lib/rabbitmq -- -pa /usr/lib/rabbitmq/lib/rabbitmq_server-3.6.16/ebin -noshell -noinput -s rabbit boot -sname rabbit@controller -boot start_sasl -config /etc/rabbitmq/rabbitmq -kernel inet_default_connect_options [{nodelay,true}] -sasl errlog_type error -sasl sasl_error_logger false -rabbit error_logger {file,"/var/log/rabbitmq/rabbit@controller.log"} -rabbit sasl_error_logger {file,"/var/log/rabbitmq/rabbit@controller-sasl.log"} -rabbit enabled_plugins_file "/etc/rabbitmq/enabled_plugins" -rabbit plugins_dir "/usr/lib/rabbitmq/plugins:/usr/lib/rabbitmq/lib/rabbitmq_server-3.6.16/plugins" -rabbit plugins_expand_dir "/var/lib/rabbitmq/mnesia/rabbit@controller-plugins-expand" -os_mon start_cpu_sup false -os_mon start_disksup false -os_mon start_memsup false -mnesia dir "/var/lib/rabbitmq/mnesia/rabbit@controller" -kernel inet_dist_listen_min 25672 -kernel inet_dist_listen_max 25672

6.查看rabbitmq日志（/var/log/rabbitmq/rabbit@controller.log ），结果显示用户openstack拥有无效凭证，如下:

=ERROR REPORT==== 15-May-2020::16:59:17 ===
Error on AMQP connection <0.17344.0> (10.0.0.20:52414 -> 10.0.0.20:5672, state: starting):

解决

[root@controller rabbitmq]# rabbitmqctl list_users

guest	[administrator]
[root@controller rabbitmq]# rabbitmqctl -q  delete_user openstack
[root@controller rabbitmq]# rabbitmqctl list_users

启动服务测试

[root@computer ~]# systemctl restart openstack-nova-compute.service
