7.1 nova计算节点准备
- 系统版本选择：CentOS Linux release 7.6.1810 (Core)
- 配置计算节点主机名
hostnamectl --static set-hostname nova
- 配置域名解析
echo "192.168.204.10 controller" >>/etc/hosts
echo "192.168.204.11 nova" >>/etc/hosts
echo "192.168.204.12 cinder" >>/etc/hosts
echo "192.168.204.13 swift" >>/etc/hosts
cat /etc/hosts
7.2 关闭防火墙和selinux
7.2.1 关闭防火墙
systemctl stop firewalld.service
systemctl disable firewalld.service
7.2.2 关闭selinux
setenforce 0
getenforce
sed -i 's#SELINUX=enforcing#SELINUX=disabled#g' /etc/sysconfig/selinux
grep SELINUX=disabled /etc/sysconfig/selinux
7.3 时间同步
7.3.1 安装chrony
yum install -y chrony
7.3.2 编辑chrony配置文件
vim /etc/chrony.conf
---
server 192.168.204.10 iburst
7.3.3 设置时区
timedatectl set-timezone Asia/Shanghai
chronyc sources
timedatectl status
7.3.4 启动并且配置自启动
systemctl restart chronyd.service
systemctl enable chronyd.service
7.4 配置yum源
使用互联网安装openstack需要配置epel与阿里源（如公司不允许服务器连接互联网可在内网自建yum源，把epel与阿里源同步到内网）
7.4.1 安装epel与阿里yum源
wget -O /etc/yum.repos.d/aliyun.repo http://mirrors.aliyun.com/repo/Centos-7.repo
wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
7.4.2 安装Rocky
yum install centos-release-openstack-rocky -y
yum clean all
yum makecache
yum update -y
7.5 安装配置nova计算节点
7.5.1 安装nova
yum install openstack-nova-compute python-openstackclient openstack-utils openstack-selinux -y
7.5.2 配置nova
openstack-config --set /etc/nova/nova.conf DEFAULT my_ip 192.168.204.11
openstack-config --set /etc/nova/nova.conf DEFAULT use_neutron True
openstack-config --set /etc/nova/nova.conf DEFAULT firewall_driver nova.virt.firewall.NoopFirewallDriver
openstack-config --set /etc/nova/nova.conf DEFAULT enabled_apis osapi_compute,metadata
openstack-config --set /etc/nova/nova.conf DEFAULT transport_url rabbit://openstack:openstack@controller
openstack-config --set /etc/nova/nova.conf api auth_strategy keystone
openstack-config --set /etc/nova/nova.conf keystone_authtoken auth_url http://controller:5000/v3
openstack-config --set /etc/nova/nova.conf keystone_authtoken memcached_servers controller:11211
openstack-config --set /etc/nova/nova.conf keystone_authtoken auth_type password
openstack-config --set /etc/nova/nova.conf keystone_authtoken project_domain_name default
openstack-config --set /etc/nova/nova.conf keystone_authtoken user_domain_name default
openstack-config --set /etc/nova/nova.conf keystone_authtoken project_name test
openstack-config --set /etc/nova/nova.conf keystone_authtoken username nova
openstack-config --set /etc/nova/nova.conf keystone_authtoken password nova
openstack-config --set /etc/nova/nova.conf vnc enabled True
openstack-config --set /etc/nova/nova.conf vnc server_listen 0.0.0.0
openstack-config --set /etc/nova/nova.conf vnc server_proxyclient_address '$my_ip'
openstack-config --set /etc/nova/nova.conf vnc novncproxy_base_url http://controller:6080/vnc_auto.html
openstack-config --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
openstack-config --set /etc/nova/nova.conf placement region_name RegionOne
openstack-config --set /etc/nova/nova.conf placement project_domain_name Default
openstack-config --set /etc/nova/nova.conf placement project_name test
openstack-config --set /etc/nova/nova.conf placement auth_type password
openstack-config --set /etc/nova/nova.conf placement user_domain_name Default
openstack-config --set /etc/nova/nova.conf placement auth_url http://controller:5000/v3
openstack-config --set /etc/nova/nova.conf placement username placement
openstack-config --set /etc/nova/nova.conf placement password placement
7.5.3 配置虚拟机硬件加速配置方案
7.5.3.1 检查计算节点是否支持虚拟机硬件加速
egrep -c '(vmx|svm)' /proc/cpuinfo
7.5.3.2 返回值为0
如果返回值为0，表示不支持硬件加速，需要配置liblibvirt使用QEMU管理虚拟机
openstack-config --set /etc/nova/nova.conf libvirt virt_type qemu
7.5.3.3 返回值不为0
如果返回值不为0，表示支持硬件加速，使用kvm配置管理虚拟机
openstack-config --set /etc/nova/nova.conf libvirt virt_type kvm
7.5.4 启动并且配置自启动
systemctl start libvirtd.service openstack-nova-compute.service
systemctl status libvirtd.service openstack-nova-compute.service
systemctl enable libvirtd.service openstack-nova-compute.service
7.5.5 将计算节点增加到cell数据库
此操作在控制节点进行操作
7.5.5.1 检查数据库有新的计算节点
source /script/admin.sh
openstack compute service list --service nova-compute
7.5.5.2 手动将计算节点添加到Openstack集群
su -s /bin/sh -c "nova-manage cell_v2 discover_hosts --verbose" nova
7.6 控制节点验证nova
7.6.1 查看nova服务组件
source /script/admin.sh
[root@controller nova]# openstack compute service list
