上一篇文章分享了glance镜像服务的安装配置，本文主要分享openstack的计算服务Nova的安装和配制方法
------------------ 完美的分割线 ---------------------
nova相关端口：
api:8774
metadata:8775
novncproxy:6080
4.1.在控制节点安装nova计算服务
1）创建nova相关数据库
# nova服务在本版本新增加了两个数据库，需要注意
mysql -u root -p123456
-----------------------------------
CREATE DATABASE nova_api;
CREATE DATABASE nova;
CREATE DATABASE nova_cell0;
CREATE DATABASE placement; GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'localhost' IDENTIFIED BY 'nova';
GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'%' IDENTIFIED BY 'nova'; GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' IDENTIFIED BY 'nova';
GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' IDENTIFIED BY 'nova'; GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'localhost' IDENTIFIED BY 'nova';
GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'%' IDENTIFIED BY 'nova'; GRANT ALL PRIVILEGES ON placement.* TO 'placement'@'localhost' IDENTIFIED BY 'placement';
GRANT ALL PRIVILEGES ON placement.* TO 'placement'@'%' IDENTIFIED BY 'placement'; flush privileges;
show databases;
select user,host from mysql.user;
exit
----------------------------------
4.2.在keystone上面注册nova服务
# 创建服务证书
1）在keystone上创建nova用户
cd /server/tools
source keystone-admin-pass.sh
openstack user create --domain default --password=nova nova
openstack user list
2）在keystone上将nova用户配置为admin角色并添加进service项目
# 以下命令无输出
openstack role add --project service --user nova admin
3）创建nova计算服务的实体
openstack service create --name nova --description "OpenStack Compute" compute
openstack service list
4）创建计算服务的API端点（endpoint）
# 计算服务compute
openstack endpoint create --region RegionOne compute public http://controller:8774/v2.1
openstack endpoint create --region RegionOne compute internal http://controller:8774/v2.1
openstack endpoint create --region RegionOne compute admin http://controller:8774/v2.1
openstack endpoint list
5）这个版本的nova增加了placement项目
# 同样，创建并注册该项目的服务证书
openstack user create --domain default --password=placement placement
openstack role add --project service --user placement admin
openstack service create --name placement --description "Placement API" placement
# 创建placement项目的endpoint（API端口）
openstack endpoint create --region RegionOne placement public http://controller:8778
openstack endpoint create --region RegionOne placement internal http://controller:8778
openstack endpoint create --region RegionOne placement admin http://controller:8778
openstack endpoint list
# 完毕
4.3.在控制节点安装nova相关服务
1）安装nova相关软件包
yum install openstack-nova-api openstack-nova-conductor \
openstack-nova-console openstack-nova-novncproxy \
openstack-nova-scheduler openstack-nova-placement-api -y
2）快速修改nova配置
openstack-config --set /etc/nova/nova.conf DEFAULT enabled_apis osapi_compute,metadata
openstack-config --set /etc/nova/nova.conf DEFAULT my_ip 192.168.1.81

openstack-config --set /etc/nova/nova.conf vnc server_listen '$my_ip'
openstack-config --set /etc/nova/nova.conf vnc server_proxyclient_address '$my_ip'
openstack-config --set /etc/nova/nova.conf glance api_servers http://controller:9292

# 至此，nova计算服务的软件包安装完成
4.4.同步nova数据（注意同步顺序）
# nova_api有32张表，placement有32张表，nova_cell0有110张表，nova也有110张表
1）初始化nova-api和placement数据库
su -s /bin/sh -c "nova-manage api_db sync" nova
# 验证数据库
mysql -h192.168.1.81 -unova -pnova -e "use nova_api;show tables;"
