控制节点配置
1. 建库建用户
CREATE DATABASE nova_api; CREATE DATABASE nova; GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'localhost' IDENTIFIED BY '123456'; GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'%' IDENTIFIED BY '123456'; GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' IDENTIFIED BY '123456'; GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' IDENTIFIED BY '123456'; flush privileges;
2. keystone相关操作

3. 安装软件包
1 yum install openstack-nova-api openstack-nova-conductor openstack-nova-console openstack-nova-novncproxy openstack-nova-scheduler -y 2 yum install openstack-nova-placement-api
4. 修改配置
vim /etc/nova/nova.conf
[DEFAULT] enabled_apis = osapi_compute,metadata rpc_backend = rabbit auth_strategy = keystone transport_url = rabbit://openstack:123456@controller #下面的为管理ip my_ip = 192.168.198.128 use_neutron = True firewall_driver = nova.virt.firewall.NoopFirewallDriver [api_database] connection = mysql+pymysql://nova:123456@controller/nova_api [database] connection = mysql+pymysql://nova:123456@controller/nova [oslo_messaging_rabbit] rabbit_host = controller rabbit_userid = openstack rabbit_password = 123456 [keystone_authtoken] auth_url = http://controller:5000 memcached_servers = controller:11211 auth_type = password project_domain_name = default user_domain_name = default project_name = service username = nova password = 123456 [vnc] enabled = True # 下面的为管理ip vncserver_listen = 192.168.198.128 # 下面的为管理ip vncserver_proxyclient_address = 192.168.198.128 [glance] api_servers = http://controller:9292 [placement] auth_url = http://controller:35357/v3 auth_type=password os_region_name = RegionOne project_domain_name = default user_domain_name = default region_name = RegionOne project_name = service username = neutron password = 123456 [oslo_concurrency] lock_path = /var/lib/nova/tmp
vim /etc/httpd/conf.d/00-nova-placement-api.conf
# append this code <Directory /usr/bin> <IfVersion >= 2.4> Require all granted </IfVersion> <IfVersion < 2.4> Order allow,deny Allow from all </IfVersion> </Directory>
5. 同步数据库
此处会报一些关于future的问题，自行忽略
1 su -s /bin/sh -c "nova-manage api_db sync" nova 2 su -s /bin/sh -c "nova-manage db sync" nova
6. 启动服务
1 systemctl enable openstack-nova-api.service openstack-nova-consoleauth.service 2 systemctl enable openstack-nova-scheduler.service openstack-nova-conductor.service openstack-nova-novncproxy.service 3 systemctl start openstack-nova-api.service openstack-nova-consoleauth.service openstack-nova-scheduler.service 4 systemctl start openstack-nova-conductor.service openstack-nova-novncproxy.service
7. 验证
netstat -ntlp | grep 6080 tcp 0 0 0.0.0.0:6080 0.0.0.0:* LISTEN 85554/python2 netstat -ntlp | grep 8774 tcp 0 0 0.0.0.0:8774 0.0.0.0:* LISTEN 85481/python2 netstat -ntlp | grep 8775 tcp 0 0 0.0.0.0:8775 0.0.0.0:* LISTEN 85481/python2
计算节点配置
1. 安装软件包
yum install openstack-nova-compute libvirt-daemon-lxc -y
2. 修改配置
vim /etc/nova/nova.conf
[DEFAULT] rpc_backend = rabbit auth_strategy = keystone #计算节点管理网络ip my_ip = 192.168.198.129 use_neutron = True firewall_driver = nova.virt.firewall.NoopFirewallDriver enabled_apis = osapi_compute,metadata transport_url = rabbit://openstack:123456@controller [oslo_messaging_rabbit] rabbit_host = controller rabbit_userid = openstack rabbit_password = 123456 [vnc] enabled = True vncserver_listen = 0.0.0.0 #计算节点管理网络ip vncserver_proxyclient_address = 192.168.198.129 #控制节点管理网络ip novncproxy_base_url = http://192.168.198.128:6080/vnc_auto.html [glance] api_servers = http://controller:9292 [oslo_concurrency] lock_path = /var/lib/nova/tmp [placement] auth_url = http://controller:5000 memcached_servers = controller:11211 auth_type = password project_domain_name = default user_domain_name = default project_name = service username = nova password = 123456 os_region_name = RegionOne [scheduler] discover_hosts_in_cells_interval = 300 [database] connection = mysql+pymysql://root:secret@192.168.111.69/nova_cell0?charset=utf8 [api_database] connection = mysql+pymysql://root:secret@192.168.111.69/nova_api?charset=utf8
3. 如果在不支持虚拟化的机器上部署nova，请确认
egrep -c '(vmx|svm)' /proc/cpuinfo结果为0 # 则编辑/etc/nova/nova.conf vim /etc/nova/nova.conf [libvirt] virt_type = qemu . admin-openrc openstack hypervisor list # Discover compute hosts su -s /bin/sh -c "nova-manage cell_v2 discover_hosts --verbose" nova
4. 启动服务
1 systemctl enable libvirtd.service openstack-nova-compute.service 2 systemctl start libvirtd.service openstack-nova-compute.service
验证
