云计算基础设施平台iaas（openstack）超级详细搭建（七）安装Nova计算服务

注意：接与上一篇博客内容 进行更新
由于整个开源openstack安装过程过于繁琐，命令太长，太繁琐，于是把整个安装命令写成shell脚本。

脚本数量内容过多，已经推送自我的github <https://github.com/pwxwmm/openstackShellScript>源码托管中心了。
这是本篇脚本内容所在的github仓库位置 controller节点
<https://github.com/pwxwmm/openstackShellScript/blob/master/iaas-install-nova-controller.sh>
compute节点
<https://github.com/pwxwmm/openstackShellScript/blob/master/iaas-install-nova-compute.sh>
[root@controller centos]# cd /usr/local/bin/这是所有需要的脚本的整个路径

4 安装Nova计算服务
4.1通过脚本安装nova服务 4.2-4.14计算服务的操作命令已经编写成shell脚本，通过脚本进行一键安装。如下： #Controller节点
执行脚本iaas-install-nova-controller.sh进行安装 #Compute节点
执行脚本iaas-install-nova-compute.sh进行安装
下面是本篇内容的命令的详细操作过程（脚本中已经包含该篇命令的所有操作，但是建议还是熟悉下整个过程之后再运行脚本）

4.2安装Nova 计算服务软件包
# yum install -y openstack-nova-api openstack-nova-conductor
openstack-nova-console openstack-nova-novncproxy openstack-nova-scheduler
4.3创建Nova数据库
# mysql -u root -p mysql> CREATE DATABASE nova; mysql> GRANT ALL PRIVILEGES ON
nova.* TO 'nova'@'localhost' IDENTIFIED BY 'NOVA_DBPASS'; mysql> GRANT ALL
PRIVILEGES ON nova.* TO 'nova'@'%' IDENTIFIED BY 'NOVA_DBPASS'; mysql> create
database IF NOT EXISTS nova_api; mysql> GRANT ALL PRIVILEGES ON nova_api.* TO '
nova'@'localhost' IDENTIFIED BY 'NOVA_DBPASS' ; mysql> GRANT ALL PRIVILEGES ON
nova_api.* TO 'nova'@'%' IDENTIFIED BY 'NOVA_DBPASS' ; 修改数据库连接 openstack-config
--set /etc/nova/nova.conf database connection
mysql+pymysql://nova:NOVA_DBPASS@controller/nova openstack-config --set
/etc/nova/nova.conf api_database connection
mysql+pymysql://nova:NOVA_DBPASS@controller/nova_api
4.4创建计算服务表
su -s /bin/sh -c "nova-manage db sync" nova su -s /bin/sh -c "nova-manage
api_db sync" nova
4.5创建用户
openstack user create --domain default --password 000000 nova openstack role
add --projectservice --user nova admin

--set /etc/nova/nova.conf glance api_servers http://controller:9292 openstack-
config--set /etc/nova/nova.conf oslo_concurrency lock_path /var/lib/nova/tmp
4.7创建Endpoint和API端点
openstack service create --name nova --description "OpenStack Compute" compute
openstack endpoint create --region RegionOne compute public
http://controller:8774/v2.1/%\(tenant_id\)s openstack endpoint create --region
RegionOne compute internal http://controller:8774/v2.1/%\(tenant_id\)s
openstack endpoint create --region RegionOne compute admin
http://controller:8774/v2.1/%\(tenant_id\)s
4.8启动服务
systemctl enable openstack-nova-api.service openstack-nova-consoleauth.service
openstack-nova-scheduler.service openstack-nova-conductor.service
openstack-nova-novncproxy.service systemctl start openstack-nova-api.service
openstack-nova-consoleauth.service openstack-nova-scheduler.service
openstack-nova-conductor.service openstack-nova-novncproxy.service
4.9验证Nova
#nova image-list
#Compute节点

4.10安装Nova计算服务软件包
yum install lvm2 -y yum install openstack-nova-compute -y
4.11配置Nova服务
openstack-config --set /etc/nova/nova.conf DEFAULT rpc_backend rabbit openstack

openstack-config --set /etc/nova/nova.conf oslo_concurrency lock_path /var/lib/
nova/tmp openstack-config --set /etc/nova/nova.conf libvirt inject_key True
4.12检查系统处理器是否支持虚拟机的硬件加速
执行命令 #egrep -c '(vmx|svm)' /proc/cpuinfo
（1）如果该命令返回一个1或更大的值,说明你的系统支持硬件加速，通常不需要额外的配置。
（2）如果这个指令返回一个0值，说明你的系统不支持硬件加速，你必须配置libvirt取代KVM来使用QEMU。 # openstack-config
--set /etc/nova/nova.conf libvirt virt_type qemu
4.13启动
systemctl enable libvirtd.service openstack-nova-compute.service systemctl
start libvirtd.service openstack-nova-compute.service
4.14 清除防火墙
controller和compute节点 iptables -F iptables -X iptables -Z
/usr/libexec/iptables/iptables.init save
