Kilo版Openstack如何删除一台计算节点

发布时间:2021-12-29 14:39:53 来源:亿速云 阅读:167 作者:小新 栏目:云计算

小编给大家分享一下Kilo版Openstack如何删除一台计算节点,希望大家阅读完这篇文章之后都有所收获,下面让我们一起去探讨吧!

1、移除计算节点上的ceph osd

停止节点上所有的osd服务

systemctl stop ceph-osd@20
systemctl stop ceph-osd@21
systemctl stop ceph-osd@22
systemctl stop ceph-osd@23

在mon节点上移除osd

ceph osd out 23
ceph osd out 22
ceph osd out 21
ceph osd out 20
ceph osd crush remove osd.23
ceph osd crush remove osd.22
ceph osd crush remove osd.21
ceph osd crush remove osd.20
ceph auth del osd.23
ceph auth del osd.22
ceph auth del osd.21
ceph auth del osd.20
ceph osd rm 23
ceph osd rm 22
ceph osd rm 21
ceph osd rm 20
ceph osd crush remove bdc8

等待集群自动恢复即可 如果配置文件中有对应osd在某台节点上的配置,需要删掉

2、移除计算节点上openstack服务

2.1、计算节点上停止服务

systemctl stop neutron-openvswitch-agent.service
systemctl stop openstack-nova-compute.service 
systemctl disable neutron-openvswitch-agent.service
systemctl disable openstack-nova-compute.service

2.2、移除计算服务

查看计算节点服务

. admin-openrc.sh 
nova service-list
+----+------------------+------+----------+---------+-------+----------------------------+-----------------+
| Id | Binary           | Host | Zone     | Status  | State | Updated_at                 | Disabled Reason |
+----+------------------+------+----------+---------+-------+----------------------------+-----------------+
| 1  | nova-cert        | bdc2 | internal | enabled | up    | 2018-03-22T02:54:42.000000 | -               |
| 2  | nova-conductor   | bdc2 | internal | enabled | up    | 2018-03-22T02:54:43.000000 | -               |
| 3  | nova-consoleauth | bdc2 | internal | enabled | up    | 2018-03-22T02:54:42.000000 | -               |
| 4  | nova-scheduler   | bdc2 | internal | enabled | up    | 2018-03-22T02:54:40.000000 | -               |
| 5  | nova-compute     | bdc3 | nova     | enabled | up    | 2018-03-22T02:54:41.000000 | -               |
| 6  | nova-compute     | bdc2 | nova     | enabled | up    | 2018-03-22T02:54:45.000000 | -               |
| 7  | nova-compute     | bdc4 | nova     | enabled | up    | 2018-03-22T02:54:42.000000 | -               |
| 8  | nova-compute     | bdc5 | nova     | enabled | up    | 2018-03-22T02:54:44.000000 | -               |
| 9  | nova-compute     | bdc6 | nova     | enabled | up    | 2018-03-22T02:54:44.000000 | -               |
| 10 | nova-compute     | bdc7 | nova     | enabled | up    | 2018-03-22T02:54:46.000000 | -               |
| 11 | nova-compute     | bdc8 | nova     | enabled | up    | 2018-03-22T02:54:39.000000 | -               |
+----+------------------+------+----------+---------+-------+----------------------------+-----------------+

删除bdc8上的计算服务

nova service-disable 11
nova service-delete 11

元数据库中删除

use nova;
select *  from compute_nodes where host='bdc2'\G
delete from compute_nodes where host='bdc2';
select * from services where host='bdc2'\G   
delete from services where host='bdc2';

2.3、移除网络服务

查看网络服务

# neutron agent-list

+--------------------------------------+--------------------+------+-------+----------------+---------------------------+
| id                                   | agent_type         | host | alive | admin_state_up | binary                    |
+--------------------------------------+--------------------+------+-------+----------------+---------------------------+
| 08bc9d33-3e67-4a06-9223-74be1c969b8a | Open vSwitch agent | bdc2 | :-)   | True           | neutron-openvswitch-agent |
| 19a31ea2-280b-42b4-9f08-c1f99182e826 | Open vSwitch agent | bdc5 | :-)   | True           | neutron-openvswitch-agent |
| 286336ae-22fd-4391-8470-aae559ee5ccb | DHCP agent         | bdc3 | :-)   | True           | neutron-dhcp-agent        |
| 42ab605e-3d66-402f-b86a-4ef246df2ecf | Open vSwitch agent | bdc8 | :-)   | True           | neutron-openvswitch-agent |
| 4791844d-07f7-43be-8b27-bcfe8d8a7791 | Open vSwitch agent | bdc6 | :-)   | True           | neutron-openvswitch-agent |
| 63c99510-205a-4f94-ac18-61082c6edb44 | L3 agent           | bdc3 | :-)   | True           | neutron-l3-agent          |
| 830a75fb-c516-4f6f-ae74-e09bfd558291 | Open vSwitch agent | bdc7 | :-)   | True           | neutron-openvswitch-agent |
| 91df9210-0a27-4933-9f03-3ccce6192011 | Open vSwitch agent | bdc4 | :-)   | True           | neutron-openvswitch-agent |
| a9f7bc30-beda-437d-92a8-be64296c57d0 | Open vSwitch agent | bdc3 | :-)   | True           | neutron-openvswitch-agent |
| cf6443f7-ef8e-4738-bfc5-e491e4f89aeb | Metadata agent     | bdc3 | :-)   | True           | neutron-metadata-agent    |
+--------------------------------------+--------------------+------+-------+----------------+---------------------------+

删除bdc8上的网络服务

# neutron agent-delete 42ab605e-3d66-402f-b86a-4ef246df2ecf
Deleted agent: 42ab605e-3d66-402f-b86a-4ef246df2ecf

3、元数据查看

nova库

MariaDB [nova]> select hypervisor_hostname,deleted_at,deleted from compute_nodes;
+---------------------+---------------------+---------+
| hypervisor_hostname | deleted_at          | deleted |
+---------------------+---------------------+---------+
| bdc3                | NULL                |       0 |
| bdc2                | NULL                |       0 |
| bdc4                | NULL                |       0 |
| bdc5                | NULL                |       0 |
| bdc6                | NULL                |       0 |
| bdc7                | NULL                |       0 |
| bdc8                | 2018-03-22 02:58:53 |       7 |
+---------------------+---------------------+---------+
MariaDB [nova]> select * from services where host = 'bdc8';
+---------------------+---------------------+---------------------+----+------+--------------+---------+--------------+----------+---------+-----------------+
| created_at          | updated_at          | deleted_at          | id | host | binary       | topic   | report_count | disabled | deleted | disabled_reason |
+---------------------+---------------------+---------------------+----+------+--------------+---------+--------------+----------+---------+-----------------+
| 2016-10-13 09:20:41 | 2018-03-22 02:58:49 | 2018-03-22 02:58:53 | 11 | bdc8 | nova-compute | compute |      4442289 |        0 |      11 | NULL            |
+---------------------+---------------------+---------------------+----+------+--------------+---------+--------------+----------+---------+-----------------+

4、删除其它节点与bdc8连通的隧道网络

先在元数据库中删除bdc8的gre信息

MariaDB [neutron]> select * from ml2_gre_endpoints;   
+-------------+------+
| ip_address  | host |
+-------------+------+
| 172.16.13.2 | bdc2 |
| 172.16.13.3 | bdc3 |
| 172.16.13.4 | bdc4 |
| 172.16.13.5 | bdc5 |
| 172.16.13.6 | bdc6 |
| 172.16.13.7 | bdc7 |
| 172.16.13.8 | bdc8 |
+-------------+------+
MariaDB [neutron]> delete from ml2_gre_endpoints where ip_address='172.16.13.8';

各个节点中删除连接bdc8的gre隧道

# ovs-vsctl show
