上一篇主要介绍了控制节点的一些安装配置，这里将会介绍openstack其它组件的相关配置。
计算节点配置nova-compute
1、node2上修改nova的配置文件：
[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.html2、检查主机是否开启了虚拟化,返回为0 则说明不支持，需要启用qemu：
egrep -c '(vmx|svm)' /proc/cpuinfo如果返回0，则在/etc/nova/nova.conf 配置使用 qemu:
[libvirt]
# ...
virt_type = qemu3、启动服务：
# systemctl enable libvirtd.service openstack-nova-compute.service
# systemctl start libvirtd.service openstack-nova-compute.service4、在node3上配置与node2上的相同。只需要修改nova.conf文件的如下两个参数：
[root@openstack-node3 ~]# grep 192.168.10.13 /etc/nova/nova.conf
vncserver_listen=192.168.10.13
vncserver_proxyclient_address=192.168.10.135、控制节点上进行验证：
[root@openstack-node1 ~]# source admin-openstack.sh
[root@openstack-node1 ~]# openstack compute service list
+----+------------------+-----------------+----------+---------+-------+----------------------------+
| ID | Binary | Host | Zone | Status | State | Updated At |

+----+------------------+-----------------+----------+---------+-------+----------------------------+6、获取计算节点信息，发现计算主机：
[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

11、在控制节点上登录虚拟机：
[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
...控制节点配置Horizon
Horizon是可以安装在任意节点上的，只要配置对应的Memcached的连接即可，在安装的Horizon的节点上启动httpd服务即可。这将dashboard安装在控制节点。
1、安装openstack-dashboard:
# yum install openstack-dashboard -y2、修改配置文件/etc/openstack-dashboard/local_settings,配置如下内容：
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,
'enable_quotas': False,
'enable_distributed_router': False,
'enable_ha_router': False,
'enable_lb': False,
'enable_firewall': False,
'enable_vpn': False,
'enable_fip_topology_check': False,
}3、重启服务：
# systemctl restart httpd.service memcached.service4、登录验证： 使用链接 http://192.168.10.11/dashboard进行登录,账号admin/admin, 或者 demo/demo。
使用demo用户登录，可以在web 界面创建虚拟机。
