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
