openstack私有云布署实践【11.1 计算nova - compute节点配置(科兴环境)】

这里我只使用kxcompute1节点配置为示例,其它节点的配置基本是一样的,只是声明的管理IP不同而已
 
计算节点
# yum install openstack-nova-compute sysfsutils
 
修改配置文件
vi /etc/nova/nova.conf
 
[DEFAULT]
vcpu_pin_set = 4-31
resume_guests_state_on_host_boot=True
rpc_backend = rabbit
auth_strategy = keystone
my_ip = 10.120.42.11
 
state_path=/home/local/nova
 
network_api_class = nova.network.neutronv2.api.API
security_group_api = neutron
linuxnet_interface_driver = nova.network.linux_net.NeutronLinuxBridgeInterfaceDriver
firewall_driver = nova.virt.firewall.NoopFirewallDriver
 
verbose = True
 
[keystone_authtoken]
auth_uri = http://kxcontroller:5000
auth_url = http://kxcontroller:35357
auth_plugin = password
project_domain_id = default
user_domain_id = default
project_name = service
username = nova
password = nova
 
[vnc]
enabled = True
vncserver_listen = 0.0.0.0
vncserver_proxyclient_address = $my_ip
novncproxy_base_url = http://kxcontroller:6080/vnc_auto.html
 
[glance]
host = kxcontroller
 
[oslo_concurrency]
lock_path = /var/lib/nova/tmp
 
[oslo_messaging_rabbit]
rabbit_host=kxcontroller
rabbit_userid = openstack
rabbit_password = openstack
 
 
[neutron]
url = http://kxcontroller:9696
auth_url = http://kxcontroller:35357
auth_plugin = password
project_domain_id = default
user_domain_id = default
region_name = RegionTwo
project_name = service
username = neutron
password = neutron
 
 
以上的紫色配置原本是要等配neutron时再加的,只是这里我提前贴出来了以便做全局维护,如果你们是新搭环境的话,这个紫色配置要等安装了neutron包再加
 
创建实例存放目录,以及赋权
mkdir -p /home/local/nova
cp -r /var/lib/nova/* /home/local/nova/
chown -R nova:nova /home/local/nova
 
启动服务已及加入开机自启
systemctl enable libvirtd.service openstack-nova-compute.service
systemctl restart libvirtd.service openstack-nova-compute.service
 
登录其中一台kxcontroller上验证:
 
source admin-openrc.sh
 
# nova endpoints
有9个endpoints服务
 
# nova image-list
 
创建Zone州示例,在kxcontroller其中1台节点上,需要注意的是,当企业的服务器资源少的,不建议将计算节点分类,因为一旦分类并运行了虚拟机,该虚拟机的迁移,调整大小,只能在原zone区域内进行,无法跨区。
 
source admin-openrc.sh
 
查看状态
nova service-list
neutron agent-list
nova aggregate-list
nova availability-zone-list
 
定义Zone名,这里定义了2个
nova aggregate-create aggregate_prd_dm prd_dm_zone
nova aggregate-create aggregate_prd_um prd_um_zone
nova host-list
 
nova aggregate-add-host aggregate_prd_um kxcompute1
nova aggregate-add-host aggregate_prd_um kxcompute2
nova aggregate-add-host aggregate_prd_um kxcompute3
nova aggregate-add-host aggregate_prd_um kxcompute4
 
nova aggregate-add-host aggregate_prd_dm kxcompute5
nova aggregate-add-host aggregate_prd_dm kxcompute6
nova aggregate-add-host aggregate_prd_dm kxcompute7
nova aggregate-add-host aggregate_prd_dm kxcompute8
nova aggregate-add-host aggregate_prd_dm kxcompute9
 
 
 验证
 
nova service-list
