Linlink~文档安装及配置控制节点的Nova服务
安装Nova软件包
yum -y install openstack-nova-api openstack-nova-scheduler openstack-nova-conductor openstack-nova-novncproxy
cat /etc/passwd | grep nova
cat /etc/group | grep nova
创建Nova数据库并授权
mysql -uroot -p000000 -e "CREATE DATABASE nova_api;"
mysql -uroot -p000000 -e "CREATE DATABASE nova_cell0;"
mysql -uroot -p000000 -e "CREATE DATABASE nova;"
mysql -uroot -p000000 -e "GRANT ALL PRIVILEGES ON nova_api.* TO nova@localhost IDENTIFIED BY '000000';"
mysql -uroot -p000000 -e "GRANT ALL PRIVILEGES ON nova_api.* TO nova@'%' IDENTIFIED BY '000000';"
mysql -uroot -p000000 -e "GRANT ALL PRIVILEGES ON nova_cell0.* TO nova@localhost IDENTIFIED BY '000000';"
mysql -uroot -p000000 -e "GRANT ALL PRIVILEGES ON nova_cell0.* TO nova@'%' IDENTIFIED BY '000000';"
mysql -uroot -p000000 -e "GRANT ALL PRIVILEGES ON nova.* TO nova@localhost IDENTIFIED BY '000000';"
mysql -uroot -p000000 -e "GRANT ALL PRIVILEGES ON nova.* TO nova@'%' IDENTIFIED BY '000000';"
修改Nova配置文件
备份
cp /etc/nova/nova.conf /etc/nova/nova.bak
grep -Ev '^$|#' /etc/nova/nova.bak > /etc/nova/nova.conf
编辑
vi /etc/nova/nova.conf
修改[api_database]和[database]
[api_database]
connection = mysql+pymysql://nova:000000@controller/nova_api
[database]
connection = mysql+pymysql://nova:000000@controller/nova
修改[api]和[keystone_authtoken]
[api]
auth_strategy = keystone
[keystone_authtoken]
auth_url = http://controller:5000
memcached_servers = controller:11211
auth_type = password
username = nova
password = 000000
project_name = project
user_domain_name = Default
project_domain_name = Default
修改[placement]
[placement]
auth_url = http://controller:5000
auth_type = password
username = placement
password = 000000
project_name = project
user_domain_name = Default
project_domain_name = Default
region_name = RegionOne
修改[glance]
[glance]
api_servers = http://controller:9292
修改[oslo_concurrency]
[oslo_concurrency]
lock_path = /var/lib/nova/tmp
修改[DEFAULT]
[DEFAULT]
enabled_apis = osapi_compute,metadata
transport_url = rabbit://rabbitmq:000000@controller:5672
my_ip = 192.168.10.160
use_neutron = true
firewall_driver = nova.virt.firewall.NoopFirewallDriver
修改[vnc]
[vnc]
enabled = true
server_listen = $my_ip
server_proxyclient_address = $my_ip
初始化Nova的数据库
su nova -s /bin/sh -c "nova-manage api_db sync"
su nova -s /bin/sh -c "nova-manage cell_v2 create_cell --name=cell"
su nova -s /bin/sh -c "nova-manage cell_v2 map_cell0"
su nova -s /bin/sh -c "nova-manage db sync" #出现Warning不用管
验证单元
nova-manage cell_v2 list_cells
Nova组件初始化
创建Nova用户并分配角色admin
openstack user create --domain default --password 000000 nova
openstack role add --project project --user nova admin
创建Nova服务及服务端点
openstack service create --name nova compute
openstack endpoint create --region RegionOne nova public http://controller:8774/v2.1
openstack endpoint create --region RegionOne nova internal http://controller:8774/v2.1
创建admin用户访问的端点
openstack endpoint create --region RegionOne nova admin http://controller:8774/v2.1
启动加开机自启
systemctl enable openstack-nova-api.service openstack-nova-scheduler.service openstack-nova-conductor.service openstack-nova-novncproxy.service
systemctl start openstack-nova-api.service openstack-nova-scheduler.service openstack-nova-conductor.service openstack-nova-novncproxy.service
查看状态
systemctl status openstack-nova-api.service openstack-nova-scheduler.service openstack-nova-conductor.service openstack-nova-novncproxy.service
检测控制节点的Nova服务
查看端口占用情况
netstat -nutpl | grep 877
查看计算服务列表
openstack compute service list
配置计算节点nova服务(配置完再回来)
发现计算节点
. admin-login
su nova -s /bin/sh -c "nova-manage cell_v2 discover_hosts --verbose"
nova-manage cell_v2 list_hosts
编辑配置文件，设置间隔60s自动发现
cp /etc/nova/nova.conf /etc/nova/nova.conf.back
vi /etc/nova/nova.conf
[scheduler]
discover_hosta_in_cells_interval = 60
systemctl restart openstack-nova-api
验证Nova服务
openstack compute service list
openstack catalog list
nova-status upgrade check
