OpenStack-Pike（二）
上一篇主要介紹了控制節點的一些安裝配置，這裏將會介紹openstack其它組件的相關配置。html
計算節點配置nova-compute
一、node2上修改nova的配置文件：node
[root@openstack-node2 ~]# egrep -v "^$|^#" /etc/nova/nova.conf [DEFAULT] use_neutron=true firewall_driver=nova.virt.firewall.NoopFirewallDriver enabled_apis=osapi_compute,metadata transport_url= rabbit://openstack:openstack@192.168.10.11 [api] auth_strategy=keystone [glance] api_servers=http://192.168.10.11:9292 [keystone_authtoken] auth_uri = http://192.168.10.11:5000 auth_url = http://192.168.10.11:35357 memcached_servers = 192.168.10.11:11211 auth_type = password project_domain_name = default user_domain_name = default project_name = service username = nova password = nova [oslo_concurrency] lock_path=/var/lib/nova/tmp [placement] os_region_name = RegionOne project_domain_name = Default project_name = service auth_type = password user_domain_name = Default auth_url = http://192.168.10.11:35357/v3 username = placement password = placement [vnc] enabled=true vncserver_listen=192.168.10.12 vncserver_proxyclient_address=192.168.10.12 novncproxy_base_url=http://192.168.10.11:6080/vnc_auto.html
二、檢查主機是否開啓了虛擬化,返回爲0 則說明不支持，須要啓用qemu：mysql
egrep -c '(vmx|svm)' /proc/cpuinfo
若是返回0，則在/etc/nova/nova.conf 配置使用 qemu:linux
[libvirt] # ... virt_type = qemu
三、啓動服務：web
# systemctl enable libvirtd.service openstack-nova-compute.service # systemctl start libvirtd.service openstack-nova-compute.service
四、在node3上配置與node2上的相同。只須要修改nova.conf文件的以下兩個參數：sql
[root@openstack-node3 ~]# grep 192.168.10.13 /etc/nova/nova.conf vncserver_listen=192.168.10.13 vncserver_proxyclient_address=192.168.10.13
五、控制節點上進行驗證：數據庫
[root@openstack-node1 ~]# source admin-openstack.sh [root@openstack-node1 ~]# openstack compute service list +----+------------------+-----------------+----------+---------+-------+----------------------------+ | ID | Binary | Host | Zone | Status | State | Updated At | +----+------------------+-----------------+----------+---------+-------+----------------------------+ | 1 | nova-consoleauth | openstack-node1 | internal | enabled | up | 2018-01-10T10:08:08.000000 | | 2 | nova-scheduler | openstack-node1 | internal | enabled | up | 2018-01-10T10:08:09.000000 | | 3 | nova-conductor | openstack-node1 | internal | enabled | up | 2018-01-10T10:08:09.000000 | | 7 | nova-compute | openstack-node2 | nova | enabled | up | 2018-01-10T10:08:11.000000 | | 8 | nova-compute | openstack-node3 | nova | enabled | up | 2018-01-10T10:08:14.000000 | +----+------------------+-----------------+----------+---------+-------+----------------------------+
六、獲取計算節點信息，發現計算主機：django
[root@openstack-node1 ~]# su -s /bin/sh -c "nova-manage cell_v2 discover_hosts --verbose" nova Found 2 cell mappings. Skipping cell0 since it does not contain hosts. Getting compute nodes from cell 'cell1': ddc4df46-fd96-4778-b312-95e8ad37e3d3 Found 2 unmapped computes in cell: ddc4df46-fd96-4778-b312-95e8ad37e3d3 Checking host mapping for compute host 'openstack-node2': eae670ef-c799-4517-8232-525a550e2658 Creating host mapping for compute host 'openstack-node2': eae670ef-c799-4517-8232-525a550e2658 Checking host mapping for compute host 'openstack-node3': f6444b6a-5850-49d1-9aff-1dd0fcab594a Creating host mapping for compute host 'openstack-node3': f6444b6a-5850-49d1-9aff-1dd0fcab594a
控制節點配置Neutron
一、建立neutron 用戶，設置密碼爲 neutron:vim
[root@openstack-node1 ~]# source admin-openstack.sh
[root@openstack-node1 ~]# openstack user create --domain default --password neutron neutron
+---------------------+----------------------------------+
| Field | Value |
+---------------------+----------------------------------+

+---------------------+----------------------------------+
二、將neutron 用戶添加到 service項目，並授予admin權限。api
# openstack role add --project service --user neutron admin
三、建立neutron 服務：
# openstack service create --name neutron --description "OpenStack Networking" network +-------------+----------------------------------+ | Field | Value | +-------------+----------------------------------+ | description | OpenStack Networking | | enabled | True | | id | a0a7183cb0b3448d887e0a3e1308a1c3 | | name | neutron | | type | network | +-------------+----------------------------------+
四、建立endpoint,分別對應internal,public,admin:
# openstack endpoint create --region RegionOne network public http://192.168.10.11:9696 +--------------+----------------------------------+ | Field | Value | +--------------+----------------------------------+ | enabled | True | | id | ca6dd31fee654983b216264d7851e1f6 | | interface | public | | region | RegionOne | | region_id | RegionOne | | service_id | a0a7183cb0b3448d887e0a3e1308a1c3 | | service_name | neutron | | service_type | network | | url | http://192.168.10.11:9696 | +--------------+----------------------------------+ # openstack endpoint create --region RegionOne network internal http://192.168.10.11:9696 +--------------+----------------------------------+ | Field | Value | +--------------+----------------------------------+ | enabled | True | | id | 21fc021061a249feb934f5f94977d848 | | interface | internal | | region | RegionOne | | region_id | RegionOne | | service_id | a0a7183cb0b3448d887e0a3e1308a1c3 | | service_name | neutron | | service_type | network | | url | http://192.168.10.11:9696 | +--------------+----------------------------------+ # openstack endpoint create --region RegionOne network admin http://192.168.10.11:9696 +--------------+----------------------------------+ | Field | Value | +--------------+----------------------------------+ | enabled | True | | id | 87b0af4ecd1c4d8fa5b08e3d1855ab2f | | interface | admin | | region | RegionOne | | region_id | RegionOne | | service_id | a0a7183cb0b3448d887e0a3e1308a1c3 | | service_name | neutron | | service_type | network | | url | http://192.168.10.11:9696 | +--------------+----------------------------------+
五、建立一個provider的網絡，修改以下配置：
[root@openstack-node1 ~]# egrep -v "^$|^#" /etc/neutron/neutron.conf [DEFAULT] auth_strategy = keystone core_plugin = ml2 service_plugins = notify_nova_on_port_status_changes = true notify_nova_on_port_data_changes = true transport_url = rabbit://openstack:openstack@192.168.10.11 [database] connection = mysql+pymysql://neutron:neutron@192.168.10.11/neutron [keystone_authtoken] auth_uri = http://192.168.10.11:5000 auth_url = http://192.168.10.11:35357 memcached_servers = 192.168.10.11:11211 auth_type = password project_domain_name = default user_domain_name = default project_name = service username = neutron password = neutron [nova] auth_url = http://192.168.10.11:35357 auth_type = password project_domain_name = default user_domain_name = default region_name = RegionOne project_name = service username = nova password = nova [oslo_concurrency] lock_path = /var/lib/neutron/tmp
六、配置/etc/neutron/plugins/ml2/ml2_conf.ini ：
[root@openstack-node1 ~]# egrep -v "^$|^#" /etc/neutron/plugins/ml2/ml2_conf.ini [ml2] type_drivers = local,flat,vlan,gre,vxlan,geneve tenant_network_types = mechanism_drivers = linuxbridge extension_drivers = port_security [ml2_type_flat] flat_networks = provider [securitygroup] enable_ipset = true
七、配置Linuxbridge agent, 修改配置文件/etc/neutron/plugins/ml2/linuxbridge_agent.ini:
[root@openstack-node1 ~]# egrep -v "^$|^#" /etc/neutron/plugins/ml2/linuxbridge_agent.ini [linux_bridge] physical_interface_mappings = provider:eth0 [securitygroup] firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver enable_security_group = true [vxlan] enable_vxlan = false
八、配置DHCP代理 /etc/neutron/dhcp_agent.ini：
[root@openstack-node1 ~]# egrep -v "^$|^#" /etc/neutron/dhcp_agent.ini [DEFAULT] interface_driver = linuxbridge dhcp_driver = neutron.agent.linux.dhcp.Dnsmasq enable_isolated_metadata = true
9 、配置metadata代理/etc/neutron/metadata_agent.ini：
[root@openstack-node1 ~]# vim /etc/neutron/metadata_agent.ini [DEFAULT] # ... nova_metadata_host = controller metadata_proxy_shared_secret = openstack # 這裏是metadata的密碼
十、在網絡服務中配置計算服務：
[root@openstack-node1 ~]# vim /etc/nova/nova.conf [neutron] url = http://192.168.10.11:9696 auth_url = http://192.168.10.11:35357 auth_type = password project_domain_name = default user_domain_name = default region_name = RegionOne project_name = service username = neutron password = neutron service_metadata_proxy = true metadata_proxy_shared_secret = openstack # 這裏是metadata的密碼
十一、建立軟鏈接：
ln -s /etc/neutron/plugins/ml2/ml2_conf.ini /etc/neutron/plugin.ini
十二、同步數據庫：
# su -s /bin/sh -c "neutron-db-manage --config-file /etc/neutron/neutron.conf \ --config-file /etc/neutron/plugins/ml2/ml2_conf.ini upgrade head" neutron
1三、重啓nova-api服務：

1四、啓動Neutron服務：
# systemctl enable neutron-server.service \ neutron-linuxbridge-agent.service neutron-dhcp-agent.service \ neutron-metadata-agent.service # systemctl start neutron-server.service \ neutron-linuxbridge-agent.service neutron-dhcp-agent.service \ neutron-metadata-agent.service
計算節點配置 Neutron
一、拷貝控制節點的neutron.conf到計算節點，去除【database】的配置：
scp -p /etc/neutron/neutron.conf 192.168.10.12:/etc/neutron/ scp -p /etc/neutron/neutron.conf 192.168.10.13:/etc/neutron/
二、拷貝控制節點的/etc/neutron/plugins/ml2/linuxbridge_agent.ini，到計算節點：
scp -p /etc/neutron/plugins/ml2/linuxbridge_agent.ini 192.168.10.12:/etc/neutron/plugins/ml2/ scp -p /etc/neutron/plugins/ml2/linuxbridge_agent.ini 192.168.10.13:/etc/neutron/plugins/ml2/
三、計算節點配置nova.conf:
# vim /etc/nova/nova.conf url = http://192.168.10.11:9696 auth_url = http://192.168.10.11:35357 auth_type = password project_domain_name = default user_domain_name = default region_name = RegionOne project_name = service username = neutron password = neutron
四、完成配置，啓動服務：
# systemctl restart openstack-nova-compute.service # systemctl enable neutron-linuxbridge-agent.service # systemctl start neutron-linuxbridge-agent.service
五、在控制節點進行驗證：

+-----------------------------+-----------------------------------------------+
提示： 當實例建立成功後，宿主機的網絡狀態會發生變化。eth0上再也不有IP地址，會建立一個橋接網卡和虛擬機網卡，控制節點的網絡也會變爲橋接模式。
八、查看虛擬機是否建立成功,顯示ACTIVE說明建立成功：
[root@openstack-node1 ~]# openstack server list +--------------------------------------+-------------------+--------+-------------------------+--------+---------+ | ID | Name | Status | Networks | Image | Flavor | +--------------------------------------+-------------------+--------+-------------------------+--------+---------+ | 91b256f0-54f2-4df1-8ae4-3649670c7813 | provider-instance | ACTIVE | provider=192.168.10.104 | cirros | m1.nano | +--------------------------------------+-------------------+--------+-------------------------+--------+---------+
九、獲取provider-instance虛擬機的vnc的web登陸連接：
[root@openstack-node1 ~]# openstack console url show provider-instance +-------+------------------------------------------------------------------------------------+ | Field | Value | +-------+------------------------------------------------------------------------------------+ | type | novnc | | url | http://192.168.10.11:6080/vnc_auto.html?token=0b5414ee-0928-4a37-9922-eb4c8512da88 | +-------+------------------------------------------------------------------------------------+
十、使用瀏覽器打開此連接，查看網絡狀態：
十一、在控制節點上登陸虛擬機：
[root@openstack-node1 ~]# ping 192.168.10.104 PING 192.168.10.104 (192.168.10.104) 56(84) bytes of data. 64 bytes from 192.168.10.104: icmp_seq=1 ttl=64 time=0.967 ms [root@openstack-node1 ~]# ssh cirros@192.168.10.104 ...
控制節點配置Horizon
Horizon是能夠安裝在任意節點上的，只要配置對應的Memcached的鏈接便可，在安裝的Horizon的節點上啓動httpd服務便可。這將dashboard安裝在控制節點。
一、安裝openstack-dashboard:
# yum install openstack-dashboard -y
二、修改配置文件/etc/openstack-dashboard/local_settings,配置以下內容：
OPENSTACK_HOST = "192.168.10.11"
ALLOWED_HOSTS = ['*']
CACHES = {
'default': {
'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache',
'LOCATION': '192.168.10.11:11211',
},
}
SESSION_ENGINE = 'django.contrib.sessions.backends.cache'
OPENSTACK_HOST = "192.168.10.11"
OPENSTACK_KEYSTONE_URL = "http://%s:5000/v3" % OPENSTACK_HOST
OPENSTACK_KEYSTONE_MULTIDOMAIN_SUPPORT = True
OPENSTACK_API_VERSIONS = {
"identity": 3,
"image": 2,
"volume": 2,
}
OPENSTACK_KEYSTONE_DEFAULT_DOMAIN = "Default"
OPENSTACK_KEYSTONE_DEFAULT_ROLE = "user"
OPENSTACK_NEUTRON_NETWORK = {
...
'enable_router': False,
