openstack-pike-HA环境部署-dashboard+增加compute节点

部署dashboard

1、首先安装dashboard软件包

yum  -y install openstack-dashboard

2、修改配置文件 /etc/openstack-dashboard/local_settings

ALLOWED_HOSTS = ['*', 'localhost']

OPENSTACK_API_VERSIONS = {

#    "data-processing": 1.1,

    "identity": 3,

    "volume": 2,

    "compute": 2,

}

OPENSTACK_KEYSTONE_MULTIDOMAIN_SUPPORT = True

OPENSTACK_KEYSTONE_DEFAULT_DOMAIN = 'Default'

CACHES = {

    'default': {

        'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache',

        'LOCATION': '192.168.148.47:11211',

    },

}

OPENSTACK_HOST = "192.168.148.200"

OPENSTACK_KEYSTONE_URL = "http://%s:5000/v3" % OPENSTACK_HOST

OPENSTACK_KEYSTONE_DEFAULT_ROLE = "user"

把配置文件copy到其他节点，注意修改locationIP

3、重新启动服务

systemctl restart httpd memcached

4、登录web界面

http://192.168.148.200/dashboard

user:admin

password:123456

domain:default

添加一个计算节点

1、在计算节点安装软件包

yum install openstack-nova-compute  -y

2、修改配置文件/etc/nova/nova.conf

[DEFAULT]

enabled_apis = osapi_compute,metadata

firewall_driver = nova.virt.firewall.NoopFirewallDriver

my_ip = 192.168.148.36

use_neutron = True

firewall_driver = nova.virt.firewall.NoopFirewallDriver

vif_plugging_is_fatal = True

vif_plugging_timeout = 300

linuxnet_interface_driver = nova.network.linux_net.LinuxOVSInterfaceDriver

[api]

auth_strategy = keystone

[cinder]

os_region_name = RegionOne

[glance]

api_servers = http://192.168.148.200:9292

[keystone_authtoken]

auth_uri = http://192.168.148.200:5000

auth_url = http://192.168.148.200:36357

memcached_servers = controller1:11211,controller2:11211,controller3:11211

auth_type = password

project_domain_name = default

user_domain_name = default

project_name = service

username = nova

password = 123456

[libvirt]

virt_type = qemu

[neutron]

url = http://192.168.148.200:9696

auth_url = http://192.168.148.200:36357

auth_type = password

project_domain_name = default

user_domain_name = default

region_name = RegionOne

project_name = service

username = neutron

password = 123456

service_metadata_proxy = True

metadata_proxy_shared_secret = 123456

[oslo_concurrency]

lock_path = /var/lib/nova/tmp

[oslo_messaging_rabbit]

rabbit_hosts = controller1:5672,controller2:5672,controller3:5672

rabbit_userid  = openstack

rabbit_password  = 123456

rabbit_ha_queues =  True

rabbit_retry_interval =  1

rabbit_retry_backoff =  2

rabbit_max_retries  = 0

[placement]

os_region_name = RegionOne

project_domain_name = Default

project_name = service

auth_type = password

user_domain_name = Default

auth_url = http://192.168.148.200:36357/v3

username = placement

password = 123456

[vnc]

enabled = True

vncserver_listen = 0.0.0.0

vncserver_proxyclient_address = $my_ip

novncproxy_base_url = http://192.168.148.200:6080/vnc_auto.html

3、测试是否支持虚拟化

egrep -c '(vmx|svm)' /proc/cpuinfo

返回值0使用qemu，有其他显示值用

[libvirt]

virt_type = qemu

4、启动服务并设置开机启动

systemctl enable libvirtd.service openstack-nova-compute.service

systemctl start libvirtd.service openstack-nova-compute.service

验证

openstack compute service list --service nova-compute

5、在任一controller节点执行，发现计算节点

su -s /bin/sh -c "nova-manage cell_v2 discover_hosts --verbose" nova

6、验证服务

openstack compute service list

7、在Identity Service中列出API的endpoint

openstack catalog list

8、neutron软件包安装

yum  -y install openstack-neutron openstack-neutron-ml2 openstack-neutron-openvswitch

9、修改配置文件/etc/neutron/neutron.conf

vi /etc/neutron/neutron.conf

[DEFAULT]

core_plugin = ml2

service_plugins = router

auth_strategy = keystone

state_path = /var/lib/neutron

allow_overlapping_ips = True

transport_url = rabbit://openstack:123456@192.168.148.200

[keystone_authtoken]

auth_uri = http://192.168.148.200:5000

auth_url = http://192.168.148.200:35357

memcached_servers = controller1:11211,controller2:11211,controller3:11211

auth_type = password

project_domain_name = default

user_domain_name = default

project_name = service

username = neutron

password = 123456

[oslo_concurrency]

lock_path = $state_path/lock

10、修改权限

chmod 640 /etc/neutron/neutron.conf

chown neutron /etc/neutron/neutron.conf

11、修改配置文件/etc/neutron/plugins/ml2/ml2_conf.ini

[ml2]

type_drivers = flat,vlan,gre,vxlan

tenant_network_types = vxlan

mechanism_drivers = openvswitch,l2population

extension_drivers = port_security

[securitygroup]

firewall_driver = neutron.agent.linux.iptables_firewall.OVSHybridIptablesFirewallDriver

enable_security_group = True

enable_ipset = True

12、启动服务并且设置开机自启动

systemctl start openvswitch

systemctl enable openvswitch

13、创建网桥

ovs-vsctl add-br br-int

14、启动openvswitch-agent服务

systemctl start neutron-openvswitch-agent

systemctl enable neutron-openvswitch-agent
