问题现象 可以看到主机名的后缀带.novalocal
[root@open-controller-1 ~]# source dawn-openstack.sh [root@open-controller-1 ~]# nova list +--------------------------------------+-------------+--------+------------+-------------+---------------------+ | ID | Name | Status | Task State | Power State | Networks | +--------------------------------------+-------------+--------+------------+-------------+---------------------+ | 818a137d-61db-41b9-9cbc-699b28227bd3 | CentOS7-1 | ACTIVE | - | Running | provider=10.0.8.111 | | 14fe356f-bdf9-4ce0-aef6-11833d9d6015 | centos7-119 | ACTIVE | - | Running | provider=10.0.8.119 | | b410b03a-5358-49d9-b52a-e5bc4fe720c8 | demo1 | ACTIVE | - | Running | provider=10.0.8.117 | | 5bfb09ea-f53e-43c2-8c42-74d3c51cbfe6 | demo10 | ACTIVE | - | Running | provider=10.0.8.118 | | 385d5ccb-7efe-4d09-ab2b-8e05619bf3d6 | demo9 | ACTIVE | - | Running | provider=10.0.8.106 | +--------------------------------------+-------------+--------+------------+-------------+---------------------+ [root@open-controller-1 ~]# ssh centos@10.0.8.119 Last login: Tue Dec 4 13:56:16 2018 from 10.0.8.11 [centos@centos7-119 ~]$ hostname centos7-119.novalocal [centos@centos7-119 ~]$ exit logout Connection to 10.0.8.119 closed. [root@open-controller-1 ~]#
在 Control node修改nova.conf
去掉这个后缀
配置为空
重启nova-api服务
[root@open-controller-1 ~]# systemctl restart openstack-nova-api.service [root@open-controller-1 ~]#
后面创建的实例查看主机名不带后缀了
[root@open-controller-1 ~]# sh show_vm.sh open-compute-1.inner.hzdgjy.cn instance-00000018 demo10 provider=10.0.8.118 open-compute-1.inner.hzdgjy.cn instance-0000000f demo1 provider=10.0.8.117 ----------------------- open-compute-2.inner.hzdgjy.cn instance-0000001b cent provider=10.0.8.119 open-compute-2.inner.hzdgjy.cn instance-0000000e demo9 provider=10.0.8.106 ----------------------- [root@open-controller-1 ~]# ssh centos@10.0.8.119 [centos@cent ~]$ hostname cent [centos@cent ~]$ sudo su - Last login: Mon Nov 5 21:30:33 CST 2018 from 10.0.8.11 on pts/0 [root@cent ~]# hostname cent [root@cent ~]#
