OpenStack部署（四）

48 阅读 0 评论
我是靠谱客的博主 迅速小蝴蝶，最近开发中收集的这篇文章主要介绍OpenStack部署（四），觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

部署版本：pike
部署环境：CentOS7.6
配置文件中所有controller可修改为控制节点ip地址
配置过程中使用 echo $? 验证命令执行情况
Compute service
计算服务NOVA
penStack Compute与OpenStack Identity进行交互以进行身份验证；用于磁盘和服务器映像的OpenStack映像服务；以及用于用户和管理界面的OpenStack仪表板。图像访问受到项目和用户的限制；每个项目的配额是有限的（例如，实例的数量）。OpenStack Compute组成：nova api服务、nova api元数据服务、nova计算服务、nova placement api服务、nova调度服务、Nova conductor模块、Nova console daemon、Nova novncproxy daemon、Nova-html5 proxy daemon、Nova xvpvncproxy daemon、The queue、SQL database

安装和配置控制节点
一、先决条件
1.创建数据库
使用数据库访问客户端以root用户身份连接到数据库服务器：

[root@controller /]# mysql -u root -p

创建nova_api, nova, nova_cell0数据库

MariaDB [(none)]> CREATE DATABASE nova_api;
Query OK, 1 row affected (0.01 sec)
MariaDB [(none)]> CREATE DATABASE nova;
Query OK, 1 row affected (0.00 sec)
MariaDB [(none)]> CREATE DATABASE nova_cell0;
Query OK, 1 row affected (0.00 sec)

赋予访问权限

MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'controller' 
->
IDENTIFIED BY 'qwer1234';
Query OK, 0 rows affected (0.01 sec)
MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'%' 
->
IDENTIFIED BY 'qwer1234';
Query OK, 0 rows affected (0.00 sec)
MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'controller' 
->
IDENTIFIED BY 'qwer1234';
Query OK, 0 rows affected (0.01 sec)
MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' 
->
IDENTIFIED BY 'qwer1234';
Query OK, 0 rows affected (0.00 sec)
MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'controller' 
->
IDENTIFIED BY 'qwer1234';
Query OK, 0 rows affected (0.00 sec)
MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'%' 
->
IDENTIFIED BY 'qwer1234';
Query OK, 0 rows affected (0.00 sec)

2.执行管理员脚本

[root@controller openrc]# source admin-openrc.sh 
[root@controller openrc]# echo $?
0

3.创建计算服务凭据
创建nova用户

[root@controller openrc]# openstack user create --domain default --password-prompt nova
User Password:
Repeat User Password:
+---------------------+----------------------------------+

| name
| nova
|
| options
| {}
|
| password_expires_at | None
|
+---------------------+----------------------------------+

将admin角色添加到nova用户

[root@controller openrc]# openstack role add --project service --user nova admin
[root@controller openrc]# echo $?
0

创建nova服务实体

[root@controller openrc]# openstack service create --name nova 
>
--description "OpenStack Compute" compute
+-------------+----------------------------------+

|
+--------------+----------------------------------+

二、安装和配置组件
1.安装对应的包

[root@controller openrc]# yum install openstack-nova-api openstack-nova-conductor 
>
openstack-nova-console openstack-nova-novncproxy 
>
openstack-nova-scheduler openstack-nova-placement-api

2.编辑 /etc/nova/nova.conf文件及修改文件内容

[root@controller openrc]# vim /etc/nova/nova.conf

[DEFAULT]
enabled_apis = osapi_compute,metadata
[api_database]
connection = mysql+pymysql://nova:qwer1234@controller/nova_api
[database]
connection = mysql+pymysql://nova:qwer1234@controller/nova
[DEFAULT]
enabled_apis = osapi_compute,metadata
transport_url = rabbit://openstack:qwer1234@controller
[api]
auth_strategy = keystone
[keystone_authtoken]
auth_uri = http://controller:5000
auth_url = http://controller:35357
memcached_servers = controller:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = nova
password = qwer1234
[DEFAULT]
enabled_apis = osapi_compute,metadata
transport_url = rabbit://openstack:qwer1234@controller
my_ip = 10.0.0.11
[DEFAULT]
enabled_apis = osapi_compute,metadata
transport_url = rabbit://openstack:qwer1234@controller
my_ip = 10.0.0.11
use_neutron = True
firewall_driver = nova.virt.firewall.NoopFirewallDriver
[vnc]
enabled = true
# ...
vncserver_listen = $my_ip
vncserver_proxyclient_address = $my_ip
[glance]
api_servers = http://controller:9292
[oslo_concurrency]
lock_path = /var/lib/nova/tmp
[placement]
# ...
os_region_name = RegionOne
project_domain_name = Default
project_name = service
auth_type = password
user_domain_name = Default
auth_url = http://controller:35357/v3
username = placement
password = qwer1234

由于存在打包错误，您必须通过向中添加以下配置来启用对Placement API的访问

[root@controller openrc]# vim /etc/httpd/conf.d/00-nova-placement-api.conf

<Directory /usr/bin>
<IfVersion >= 2.4>
Require all granted
</IfVersion>
<IfVersion < 2.4>
Order allow,deny
Allow from all
</IfVersion>
</Directory>

重启httpd服务

[root@controller openrc]# systemctl restart httpd
[root@controller openrc]# echo $?
0

3.填充nova api数据库：

[root@controller openrc]# su -s /bin/sh -c "nova-manage api_db sync" nova
[root@controller openrc]# echo $?
0

4.注册cell0数据库：

[root@controller openrc]# su -s /bin/sh -c "nova-manage cell_v2 map_cell0" nova
[root@controller openrc]# echo $?
0

5.创建cell1单元：

[root@controller openrc]# su -s /bin/sh -c "nova-manage cell_v2 create_cell --name=cell1 --verbose" nova
4eae6503-2add-42ce-bdd0-60545f4c7a2a

6.填充nova数据库：

[root@controller openrc]# su -s /bin/sh -c "nova-manage db sync" nova
[root@controller openrc]# echo $?
0

7.验证nova的cell0和cell1已经正确注册

[root@controller openrc]# nova-manage cell_v2 list_cells
+-------+--------------------------------------+---------------------------------------+----------------------------------------------------+
|
Name |
UUID
|
Transport URL
|
Database Connection
|
+-------+--------------------------------------+---------------------------------------+----------------------------------------------------+
| cell0 | 00000000-0000-0000-0000-000000000000 |
none:/
| mysql+pymysql://nova:****@controller/nova_cell0 |
| cell1 | 4eae6503-2add-42ce-bdd0-60545f4c7a2a | rabbit://openstack:****@controller |
mysql+pymysql://nova:****@controller/nova
|
+-------+--------------------------------------+---------------------------------------+----------------------------------------------------+

三、完成安装
启动计算服务，并将其配置为在系统启动时启动：

[root@controller openrc]# systemctl enable openstack-nova-api.service 
>
openstack-nova-consoleauth.service openstack-nova-scheduler.service 
>
openstack-nova-conductor.service openstack-nova-novncproxy.service
Created symlink from /etc/systemd/system/multi-user.target.wants/openstack-nova-api.service to /usr/lib/systemd/system/openstack-nova-api.service.
Created symlink from /etc/systemd/system/multi-user.target.wants/openstack-nova-consoleauth.service to /usr/lib/systemd/system/openstack-nova-consoleauth.service.
Created symlink from /etc/systemd/system/multi-user.target.wants/openstack-nova-scheduler.service to /usr/lib/systemd/system/openstack-nova-scheduler.service.
Created symlink from /etc/systemd/system/multi-user.target.wants/openstack-nova-conductor.service to /usr/lib/systemd/system/openstack-nova-conductor.service.
Created symlink from /etc/systemd/system/multi-user.target.wants/openstack-nova-novncproxy.service to /usr/lib/systemd/system/openstack-nova-novncproxy.service.
[root@controller openrc]# systemctl start openstack-nova-api.service 
>
openstack-nova-consoleauth.service openstack-nova-scheduler.service 
>
openstack-nova-conductor.service openstack-nova-novncproxy.service
[root@controller openrc]# echo $?
0

安装并配置计算节点
一、安装和配置组件
1.安装软件包

[root@controller network-scripts]# yum install openstack-nova-compute

2.编辑/etc/nova/nova.conf文件及修改内容

[root@controller network-scripts]# vim /etc/nova/nova.conf

[DEFAULT]
enabled_apis = osapi_compute,metadata
[api_database]
connection = mysql+pymysql://nova:qwer1234@controller/nova_api
[DEFAULT]
enabled_apis = osapi_compute,metadata
transport_url = rabbit://openstack:qwer1234@controller
[api]
auth_strategy = keystone
[keystone_authtoken]
auth_uri = http://controller:5000
auth_url = http://controller:35357
memcached_servers = controller:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = nova
password = qwer1234
[DEFAULT]
enabled_apis = osapi_compute,metadata
transport_url = rabbit://openstack:qwer1234@controller
my_ip = 10.0.0.11
[DEFAULT]
enabled_apis = osapi_compute,metadata
transport_url = rabbit://openstack:qwer1234@controller
my_ip = 10.0.0.11
use_neutron = True
firewall_driver = nova.virt.firewall.NoopFirewallDriver
[vnc]
enabled = true
# ...
vncserver_listen = 0.0.0.0
vncserver_proxyclient_address = $my_ip
novncproxy_base_url = http://controller:6080/vnc_auto.html
[glance]
api_servers = http://controller:9292
[oslo_concurrency]
lock_path = /var/lib/nova/tmp
[placement]
os_region_name = RegionOne
project_domain_name = Default
project_name = service
auth_type = password
user_domain_name = Default
auth_url = http://controller:35357/v3
username = placement
password = qwer1234

二、完成安装
1.确定计算节点是否支持虚拟机的硬件加速：

[root@controller network-scripts]# egrep -c '(vmx|svm)' /proc/cpuinfo
0

如果此命令返回一个或更大的值，则计算节点支持硬件加速，通常不需要额外配置。
如果此命令返回的值为零，则计算节点不支持硬件加速，必须将libvirt配置为使用QEMU而不是KVM。

编辑/etc/nova/nova.conf文件中的[libvirt]部分：

[root@controller network-scripts]# vim /etc/nova/nova.conf

[libvirt]
virt_type = qemu

2.启动计算服务，包括其依赖项，并将其配置为在系统引导时自动启动：

[root@controller /]# systemctl enable libvirtd.service openstack-nova-compute.service
[root@controller /]# echo $?
0
[root@controller /]# systemctl start libvirtd.service openstack-nova-compute.service
[root@controller /]# echo $?
0

三、添加计算节点到cell数据库
1.获取管理员凭据以启用仅限管理员的CLI命令，然后确认数据库中有计算主机：

[root@controller openrc]# source admin-openrc.sh 
[root@controller openrc]# openstack compute service list --service nova-compute
+----+--------------+------------+------+---------+-------+----------------------------+
| ID | Binary
| Host
| Zone | Status
| State | Updated At
|
+----+--------------+------------+------+---------+-------+----------------------------+
|
8 | nova-compute | controller | nova | enabled | up
| 2022-02-23T03:10:06.000000 |
+----+--------------+------------+------+---------+-------+----------------------------+

2.发现compute hosts

[root@controller openrc]# su -s /bin/sh -c "nova-manage cell_v2 discover_hosts --verbose" nova
Found 2 cell mappings.
Skipping cell0 since it does not contain hosts.
Getting computes from cell 'cell1': 4eae6503-2add-42ce-bdd0-60545f4c7a2a
Checking host mapping for compute host 'controller': 172300fb-478d-4710-af2f-bf6579252d79
Creating host mapping for compute host 'controller': 172300fb-478d-4710-af2f-bf6579252d79
Found 1 unmapped computes in cell: 4eae6503-2add-42ce-bdd0-60545f4c7a2a

可以通过
nova service-list
openstack hypervisor list
openstack compute service list
来查看服务运行情况

[root@controller openrc]# openstack compute service list
+----+------------------+-----------------------+----------+---------+-------+----------------------------+

| 2022-02-23T03:15:36.000000 |
+----+------------------+-----------------------+----------+---------+-------+----------------------------+

3.列出标识服务中的API端点，以验证与标识服务的连接：

[root@controller openrc]# openstack catalog list
+-----------+-----------+-----------------------------------------+
| Name
| Type
| Endpoints
|
+-----------+-----------+-----------------------------------------+
| keystone

|
|
|
|
+-----------+-----------+-----------------------------------------+

4.列出图像服务中的图像以验证与图像服务的连接(没有装镜像所以为空)：

[root@controller openrc]# openstack image list
[root@controller openrc]# glance image-list
+----+------+
| ID | Name |
+----+------+
+----+------+

5.检查cell和placement API是否正常工作：

[root@controller openrc]# nova-status upgrade check
Option "os_region_name" from group "placement" is deprecated. Use option "region-name" from group "placement".
+--------------------------------+
