openstack安装newton版本Nova部署（三）
一、控制节点安装部署Nova
Nova 包含API（负责接收相应外部请求，支持OpenStackAPI，EC2API）；cert:负责身份认证；schedule：用于云主机调度(虚拟机创建在哪台主机上)；conductor：计算节点访问数据中间件；consoleauth：用户控制台授权验证；novncproxy：vnc代理。
1、安装
[root@linux-node1 ~]#yum install openstack-nova-api openstack-nova-cert openstack-nova-conductor openstack-nova-console openstack-nova-novncproxy openstack-nova-scheduler python-novaclient -y
2、创建用户：
[root@linux-node1 ~]# openstack user create --domain default --password=nova nova
+---------------------+----------------------------------+
| Field | Value |
+---------------------+----------------------------------+
| domain_id | d21d0715890447fb87f72e85dce6d4be |
| enabled | True |
| id | 5fbc8074b56843b0a1cdb7d4730bb7fa |
| name | nova |
| password_expires_at | None |
+---------------------+----------------------------------+
[root@linux-node1 ~]# openstack role add --project service --user nova admin
3、修改nova的配置文件，配置结果如下
[root@linux-node1 ~]# vi /etc/nova/nova.conf
[database]
connection=mysql://nova:nova@172.22.0.218/nova
[api_database]

:vncserver_proxyclient_address=$my_ip
4、数据库同步并检查：
[root@linux-node1 ~]# su -s /bin/sh -c "nova-manage db sync" nova
[root@linux-node1 ~]# su -s /bin/sh -c "nova-manage api_db sync" nova

二、启动Nova并注册：
1、开机启动
[root@linux-node1 ~]# systemctl enable openstack-nova-api.service openstack-nova-cert.service openstack-nova-consoleauth.service openstack-nova-scheduler.service openstack-nova-conductor.service openstack-nova-novncproxy.service
2、在keystone上注册nova，并检查控制节点的nova服务是否配置成功
[root@linux-node1 ~]# openstack service create --name nova --description "OpenStack Compute" compute
+-------------+----------------------------------+
| Field | Value |
+-------------+----------------------------------+
| description | OpenStack Compute |
| enabled | True |

三、计算节点环境准备
1、Nova compute 计算节点的安装部署
1）环境部署安装：
[root@linux-node2 ~]# yum install http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-5.noarch.rpm -y
[root@linux-node2 ~]# yum install centos-release-openstack-newton -y
[root@linux-node2 ~]# yum install python-openstackclient -y
[root@linux-node2 ~]#yum install openstack-nova-compute sysfsutils -y
2）开始部署计算节点
更改计算节点上的配置文件，直接使用控制节点的配置文件
[root@linux-node1 ~]# scp /etc/nova/nova.conf 172.22.0.209:/etc/nova
过滤配置文件有些需要更改：
[root@linux-node2 ~]# grep -n '^[a-z]' /etc/nova/nova.conf
:auth_strategy=keystone
:use_neutron = True
:my_ip=172.22.0.209
:enabled_apis=osapi_compute,metadata
:firewall_driver = nova.virt.firewall.NoopFirewallDriver
:transport_url=rabbit://openstack:openstack@172.22.0.218
:rpc_backend=rabbit
:connection=mysql://nova:nova@172.22.0.218/nova
:connection=mysql://nova:nova@172.22.0.218/nova
:api_servers=http://172.22.0.218:9292
:auth_uri = http://172.22.0.218:5000
:auth_url = http://172.22.0.218:35357
:auth_plugin = password
:memcached_servers = 172.22.0.218:
:project_domain_id = d21d0715890447fb87f72e85dce6d4be
:user_domain_id = d21d0715890447fb87f72e85dce6d4be
:project_name = service
:username = nova
:password = nova
:virt_type=qemu
:lock_path=/var/lib/nova/tmp
:rabbit_host=172.22.0.218
:rabbit_port=
:rabbit_userid=openstack
:rabbit_password=openstack
:enabled=true
:keymap=en-us
:vncserver_listen=0.0.0.0
:vncserver_proxyclient_address=$my_ip
:novncproxy_base_url=http://172.22.0.218:6080/vnc_auto.html
3）启动计算节点的libvirt和nova-compute
[root@linux-node2 ~]# systemctl enable libvirtd openstack-nova-compute
Created symlink from /etc/systemd/system/multi-user.target.wants/openstack-nova-compute.service to /usr/lib/systemd/system/openstack-nova-compute.service.
[root@linux-node2 ~]# systemctl start libvirtd openstack-nova-compute
2、安装时间服务：
[root@linux-node2 ~]# yum install chrony -y
[root@linux-node2 ~]# cat /etc/chrony.conf
# Use public servers from the pool.ntp.org project.
# Please consider joining the pool (http://www.pool.ntp.org/join.html).
server 172.22.0.218 iburst
[root@linux-node2 ~]# timedatectl set-timezone Asia/Shanghai
[root@linux-node2 ~]# timedatectl status
Local time: Wed -- :: CST
Universal time: Tue -- :: UTC
RTC time: Tue -- ::
Time zone: Asia/Shanghai (CST, +)
NTP enabled: yes
NTP synchronized: no
RTC in local TZ: no
DST active: n/a
[root@linux-node2 ~]# systemctl enable chronyd.service
[root@linux-node2 ~]# systemctl start chronyd.service
[root@linux-node2 ~]# chronyc sources
Number of sources =
MS Name/IP address Stratum Poll Reach LastRx Last sample
===============================================================================
^? linux-node1 - +0ns[ +0ns] +/- 0ns
四、查看是否部署成功：
1、在控制节点中查看注册的host,最后一个compute即是注册的host
[root@linux-node1 ~]# openstack host list
+-------------+-------------+----------+
| Host Name | Service | Zone |
+-------------+-------------+----------+
| linux-node1 | conductor | internal |
| linux-node1 | consoleauth | internal |
| linux-node1 | cert | internal |
| linux-node1 | scheduler | internal |
| linux-node2 | compute | nova |
+-------------+-------------+----------+
2、在控制节点中测试nova和glance连接正常，nova链接keystone是否正常
[root@linux-node1 ~]# nova image-list
WARNING: Command image-list is deprecated and will be removed after Nova 15.0. is released. Use python-glanceclient or openstackclient instead.
