OpenStack 运维 - 部署Nova组件
一、创建Nova数据库并执行授权操作
CT控制节点
mysql -u root -p
create database nova_api
create database nova
create database nova_cell0;
grant all privileges on nova_api.* to 'nova'@'localhost' identified by 'NOVA_DBPASS';
grant all privileges on nova_api.* to 'nova'@'%' identified by 'NOVA_DBPASS';
grant all privileges on nova.* to 'nova'@'localhost' identified by 'NOVA_DBPASS';
grant all privileges on nova.* to 'nova'@'%' identified by 'NOVA_DBPASS';
grant all privileges on nova_cell0.* to 'nova'@'localhost' identified by 'NOVA_DBPASS';
grant all privileges on nova_cell0.* to 'nova'@'%' identified by 'NOVA_DBPASS';
flush privileges;
exit
二、管理Nova用户及服务
① 创建Nova用户
#把nova用户添加到service项目，拥有admin权限
openstack user create --domain default --password NOVA_PASS nova
openstack role add --project service --user nova admin
② 创建Nova服务
openstack service create --name nova --description "OpenStack Compute" compute
③ Nova关联endpoint端点
openstack endpoint create --region RegionOne compute public http://ct:8774/v2.1
openstack endpoint create --region RegionOne compute internal http://ct:8774/v2.1
openstack endpoint create --region RegionOne compute admin http://ct:8774/v2.1
④ 安装Nova组件
yum -y install openstack-nova-api openstack-nova-conductor openstack-nova-novncproxy openstack-nova-scheduler
⑤ 修改配置文件
cp -a /etc/nova/nova.conf,.bak
grep -Ev '^$|#' /etc/nova/nova.conf.bak > /etc/nova/nova.conf
#修改nova.conf
openstack-config --set /etc/nova/nova.conf DEFAULT enabled_apis osapi_compute,metadata
openstack-config --set /etc/nova/nova.conf DEFAULT my_ip 192.168.1.100 ####修改为 ct的IP（内部IP）

⑥ 初始化数据库
su -s /bin/sh -c "nova-manage api_db sync" nova
su -s /bin/sh -c "nova-manage cell_v2 map_cell0" nova
#创建cell单元格
su -s /bin/sh -c "nova-manage cell_v2 create_cell --name=cell1 --verbose" nova
su -s /bin/sh -c "nova-manage db sync" nova
验证cell0和cell1是否注册成功
su -s /bin/sh -c "nova-manage cell_v2 list_cells" nova
查看日志文件
tail -f /var/log/nova/nova-manage.log
⑦ 启动Nova服务并查看端口
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
netstat -tnlup|egrep '8774|8775'
curl http://ct:8774
【netstat】命令用于显示各种网络相关信息
【-tnlup】选项组合使用
-t：仅显示tcp相关选项
-n：拒绝显示别名，能显示数字的全部转化为数字
-l：仅列出在Listen（监听）下的服务状态
-u：仅显示udp相关选项
-p：显示建立相关链接的程序名
【curl】命令用于模拟http浏览器发起访问向ct：8774，用作测试
三、计算节点配置 Nova 服务
C1/C2节点
① 安装nova-computer插件
yum -y install openstack-nova-compute
② 修改配置文件
cp -a /etc/nova/nova.conf,.bak
grep -Ev '^$|#' /etc/nova/nova.conf.bak > /etc/nova/nova.conf
#注意修改本机IP
openstack-config --set /etc/nova/nova.conf DEFAULT enabled_apis osapi_compute,metadata
openstack-config --set /etc/nova/nova.conf DEFAULT transport_url rabbit://openstack:RABBIT_PASS@ct
openstack-config --set /etc/nova/nova.conf DEFAULT my_ip 192.168.1.250
openstack-config --set /etc/nova/nova.conf DEFAULT use_neutron true
openstack-config --set /etc/nova/nova.conf DEFAULT firewall_driver nova.virt.firewall.NoopFirewallDriver
openstack-config --set /etc/nova/nova.conf api auth_strategy keystone
openstack-config --set /etc/nova/nova.conf keystone_authtoken auth_url http://ct:5000/v3
openstack-config --set /etc/nova/nova.conf keystone_authtoken memcached_servers ct:11211
openstack-config --set /etc/nova/nova.conf keystone_authtoken auth_type password
openstack-config --set /etc/nova/nova.conf keystone_authtoken project_domain_name Default
openstack-config --set /etc/nova/nova.conf keystone_authtoken user_domain_name Default
openstack-config --set /etc/nova/nova.conf keystone_authtoken project_name service
openstack-config --set /etc/nova/nova.conf keystone_authtoken username nova
openstack-config --set /etc/nova/nova.conf keystone_authtoken password NOVA_PASS
openstack-config --set /etc/nova/nova.conf vnc enabled true
openstack-config --set /etc/nova/nova.conf vnc server_listen 0.0.0.0
openstack-config --set /etc/nova/nova.conf vnc server_proxyclient_address ' $my_ip'
openstack-config --set /etc/nova/nova.conf vnc novncproxy_base_url http://192.168.1.250:6080/vnc_auto.html
openstack-config --set /etc/nova/nova.conf glance api_servers http://ct:9292
openstack-config --set /etc/nova/nova.conf oslo_concurrency lock_path /var/lib/nova/tmp
openstack-config --set /etc/nova/nova.conf placement region_name RegionOne
openstack-config --set /etc/nova/nova.conf placement project_domain_name Default
openstack-config --set /etc/nova/nova.conf placement project_name service
openstack-config --set /etc/nova/nova.conf placement auth_type password
openstack-config --set /etc/nova/nova.conf placement user_domain_name Default
openstack-config --set /etc/nova/nova.conf placement auth_url http://ct:5000/v3
openstack-config --set /etc/nova/nova.conf placement username placement
openstack-config --set /etc/nova/nova.conf placement password PLACEMENT_PASS
openstack-config --set /etc/nova/nova.conf libvirt virt_type qemu
③ 开启服务
systemctl enable libvirtd.service openstack-nova-compute.service
systemctl start libvirtd.service openstack-nova-compute.service
四、在控制节点测试计算节点
openstack compute service list --service nova-compute
② 扫描当前有几个可用的计算节点
#扫描到可用节点后，会将其创建到cell中，后续就可以在cell中创建虚拟机
su -s /bin/sh -c "nova-manage cell_v2 discover_hosts --verbose" nova
③ 修改控制nova的配置文件
vim /etc/nova/nova.conf
[scheduler]
#每300秒扫描一次
discover_hosts_in_cells_interval = 300
systemctl restart openstack-nova-api.service
④ 验证计算节点服务
openstack compute service list
⑤ 查看各个组件API是否正常
openstack catalog list
⑥ 查看镜像
openstack image list
⑦ 查看cell API和Placement API是否正常
nova-status upgrade check
