云计算之openstack-newton版搭建（六）
nova计算节点服务安装
安装配置计算节点
安装软件包
# yum install openstack-nova-compute -y
2.编辑/etc/nova/nova.conf
[root@compute1 ~]# cd /etc/nova/ [root@compute1 nova]# cp nova.conf nova.conf.bak [root@compute1 nova]# egrep -v "^#|^$" nova.conf.bak > nova.conf [root@compute1 nova]# vim nova.conf 添加如下内容
[DEFAULT] ... enabled_apis = osapi_compute,metadata transport_url = rabbit://openstack:RABBIT_PASS@controller auth_strategy = keystone my_ip = 192.168.23.61 use_neutron = True firewall_driver = nova.virt.firewall.NoopFirewallDriver
[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 = 123456
[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
3.确定计算节点是否支持虚拟化。
# egrep -c '(vmx|svm)' /proc/cpuinfo 如果返回值大于1表示支持虚拟化
如果不支持请更改/etc/nova/nova.conf
[libvirt] ... virt_type = qemu
4.启动服务
# systemctl enable libvirtd.service openstack-nova-compute.service # systemctl start libvirtd.service openstack-nova-compute.service
如果nova-compute服务无法启动，请检查/var/log/nova/nova-compute.log。控制器上的错误消息AMQP服务器：5672无法访问可能表示控制器节点上的防火墙阻止访问端口5672，关闭防火墙和selinux即可。
5.在控制端进行检查
# . admin-openrc
# openstack compute service list
[root@controller ~]# openstack compute service list +----+------------------+----------------------+----------+---------+-------+----------------------------+ | ID | Binary | Host | Zone | Status | State | Updated At | +----+------------------+----------------------+----------+---------+-------+----------------------------+ | 1 | nova-conductor | controller.novalocal | internal | enabled | up | 2017-01-13T01:48:04.000000 | | 2 | nova-consoleauth | controller.novalocal | internal | enabled | up | 2017-01-13T01:48:07.000000 | | 3 | nova-scheduler | controller.novalocal | internal | enabled | up | 2017-01-13T01:48:04.000000 | | 10 | nova-compute | compute1.novalocal | nova | enabled | up | 2017-01-13T01:48:09.000000 | +----+------------------+----------------------+----------+---------+-------+----------------------------+ [root@controller ~]# nova service-list +----+------------------+----------------------+----------+---------+-------+----------------------------+-----------------+ | Id | Binary | Host | Zone | Status | State | Updated_at | Disabled Reason | +----+------------------+----------------------+----------+---------+-------+----------------------------+-----------------+ | 1 | nova-conductor | controller.novalocal | internal | enabled | up | 2017-01-13T01:48:24.000000 | - | | 2 | nova-consoleauth | controller.novalocal | internal | enabled | up | 2017-01-13T01:48:17.000000 | - | | 3 | nova-scheduler | controller.novalocal | internal | enabled | up | 2017-01-13T01:48:24.000000 | - | | 10 | nova-compute | compute1.novalocal | nova | enabled | up | 2017-01-13T01:48:19.000000 | - | +----+------------------+----------------------+----------+---------+-------+----------------------------+-----------------+
