OpenStack搭建私有云04

本节开始安装Nova服务，Nova用于管理虚拟计算，在CT01和PC01分别进行相关模块的安装。

一、首先在CT01，安装相关模块

1、新建数据库

CREATE DATABASE nova_api;
CREATE DATABASE nova;
CREATE DATABASE nova_cell0;

GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'localhost' IDENTIFIED BY 'nova';
GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'%' IDENTIFIED BY 'nova';
GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' IDENTIFIED BY 'nova';
GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' IDENTIFIED BY 'nova';
GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'localhost' IDENTIFIED BY 'nova';
GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'%' IDENTIFIED BY 'nova';

2、新建用户及endpoint

. admin-openrc
openstack user create --domain default --password-prompt nova
openstack role add --project serviceproject --user nova admin
openstack service create --name nova --description "OpenStack Compute" compute

openstack endpoint create --region Region01 compute public http://CT01:8774/v2.1
openstack endpoint create --region Region01 compute internal http://CT01:8774/v2.1
openstack endpoint create --region Region01 compute admin http://CT01:8774/v2.1

openstack user create --domain default --password-prompt placement
openstack role add --project serviceproject --user placement admin
openstack service create --name placement --description "Placement API" placement

openstack endpoint create --region Region01 placement public http://CT01:8778
openstack endpoint create --region Region01 placement internal http://CT01:8778
openstack endpoint create --region Region01 placement admin http://CT01:8778

3、安装nova

apt install nova-api nova-conductor nova-consoleauth nova-novncproxy nova-scheduler nova-placement-api

4、修改配置文件
/etc/nova/nova.conf

[api_database]
connection = mysql+pymysql://nova:nova@CT01/nova_api

[database]
connection = mysql+pymysql://nova:nova@CT01/nova

[api]
auth_strategy = keystone

[keystone_authtoken]
auth_uri = http://CT01:5000
auth_url = http://CT01:35357
memcached_servers = CT01:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = serviceproject
username = nova
password = nova

[vnc]
enabled = true
vncserver_listen = $my_ip
vncserver_proxyclient_address = $my_ip

[glance]
api_servers = http://CT01:9292

[oslo_concurrency]
lock_path = /var/lib/nova/tmp

[placement]
os_region_name = Region01
project_domain_name = Default
project_name = serviceproject
auth_type = password
user_domain_name = Default
auth_url = http://CT01:35357/v3
username = placement
password = placement

[DEFAULT]
transport_url = rabbit://openstack:openstack@CT01
my_ip = 10.0.3.10
use_neutron = True
firewall_driver = nova.virt.firewall.NoopFirewallDriver
#移除下面的节点
#log_dir 

5、初始化

sudo su -s /bin/sh -c "nova-manage api_db sync" nova
sudo su -s /bin/sh -c "nova-manage cell_v2 map_cell0" nova
sudo su -s /bin/sh -c "nova-manage cell_v2 create_cell --name=cell1 --verbose" nova
sudo su -s /bin/sh -c "nova-manage db sync" nova
sudo nova-manage cell_v2 list_cells

6、重启服务

sudo service nova-api restart
sudo service nova-consoleauth restart
sudo service nova-scheduler restart
sudo service nova-conductor restart
sudo service nova-novncproxy restart

二、然后在PC01，安装相关模块
1、安装

apt install nova-compute
apt install nova-compute-qemu

2、修改配置
2.1、 /etc/nova/nova.conf

[DEFAULT]
transport_url = rabbit://openstack:openstack@CT01
my_ip = 10.0.3.11
use_neutron = True
firewall_driver = nova.virt.firewall.NoopFirewallDriver
#log_dir

[api]
auth_strategy = keystone

[keystone_authtoken]
auth_uri = http://CT01:5000
auth_url = http://CT01:35357
memcached_servers = CT01:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = serviceproject
username = nova
password = nova

[vnc]
enabled = True
vncserver_listen = 0.0.0.0
vncserver_proxyclient_address = $my_ip
novncproxy_base_url = http://CT01:6080/vnc_auto.html

[glance]
api_servers = http://CT01:9292

[oslo_concurrency]
lock_path = /var/lib/nova/tmp

[placement]
os_region_name = Region01
project_domain_name = Default
project_name = serviceproject
auth_type = password
user_domain_name = Default
auth_url = http://CT01:35357/v3
username = placement
password = placement

2.2、 /etc/nova/nova-compute.conf

[libvirt]
#egrep -c '(vmx|svm)' /proc/cpuinfo
#如果命令等于0，要改为qemu
virt_type = qemu

3、重启服务

service nova-compute restart

三、然后在CT01，进行相关操作
1、将PC01加入管理
1A、执行命令

. admin-openrc
openstack hypervisor list
sudo su -s /bin/sh -c "nova-manage cell_v2 discover_hosts --verbose" nova
[code]

1B、修改配置文件
/etc/nova/nova.conf
[code lang="shell"]
[scheduler]
discover_hosts_in_cells_interval = 300

2、验证安装

. admin-openrc
openstack compute service list
openstack catalog list
openstack image list
