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
