Openstack 云计算（二）： Openstack Rocky部署三 nova 部署与验证 (计算节点)

openstack系列

  • 一：nova计算节点初始化
  • 二：nova 计算节点配置

一： nova计算节点初始化

1.2 关闭防火墙和selinux

  1. systemctl stop firewalld.service
  2. systemctl disable firewalld.service
  3. systemctl status firewalld.service
  5. 关闭 selinux
  7. setenforce 0
  8. getenforce
  9. sed -i 's#SELINUX=enforcing#SELINUX=disabled#g' /etc/sysconfig/selinux
  10. grep SELINUX=disabled /etc/sysconfig/selinux

1.3 配置时间同步

  1. 1）在在计算节点配置时间同步服务
  2. # 安装时间同步的软件包
  4. yum install chrony -y
  5. 2）编辑配置文件确认有以下配置
  6. vim /etc/chrony.conf
  7. -------------------------------------
  8. # 修改引用控制节点controller的IP
  9. server 10.0.0.11 iburst
  10. -------------------------------------
  11. 3）重启chronyd服务，并配置开机自启动
  12. systemctl restart chronyd.service
  13. systemctl status chronyd.service
  14. systemctl enable chronyd.service
  15. systemctl list-unit-files |grep chronyd.service
  16. 4）设置时区，首次同步时间
  17. timedatectl set-timezone Asia/Shanghai
  18. chronyc sources -v 
  19. timedatectl status
  20. # 至此，时间同步配置完成

1.6 配置虚拟机的硬件加速

  1. # 首先确定您的计算节点是否支持虚拟机的硬件加速。
  3. egrep -c '(vmx|svm)' /proc/cpuinfo
  4. # 如果返回位0，表示计算节点不支持硬件加速，需要配置libvirt使用QEMU方式管理虚拟机，使用以下命令：
  6. openstack-config --set  /etc/nova/nova.conf libvirt virt_type  qemu
  7. egrep -v "^#|^$" /etc/nova/nova.conf|grep 'virt_type'
  8. # 如果返回为其他值，表示计算节点支持硬件加速且不需要额外的配置，使用以下命令：
  10. openstack-config --set  /etc/nova/nova.conf libvirt virt_type  kvm 
  11. egrep -v "^#|^$" /etc/nova/nova.conf|grep 'virt_type'

image_1d8nfea7s1qtpo92ibm1rrc1goa3k.png-50kB

  1. 启动nova相关服务，并配置为开机自启动
  2. 需要启动2个服务
  4. systemctl start libvirtd.service openstack-nova-compute.service 
  5. systemctl status libvirtd.service openstack-nova-compute.service
  6. systemctl enable libvirtd.service openstack-nova-compute.service
  7. systemctl list-unit-files |grep libvirtd.service
  8. systemctl list-unit-files |grep openstack-nova-compute.service

image_1d8nfhc0j1q8mcql13551obiu0q41.png-265.7kB

1.7 将计算节点增加到cell数据库

  1. # 以下命令在控制节点操作：
  3. cd /openstack
  4. source keystone-admin-pass.sh 
  5. # 检查确认数据库有新的计算节点
  7. openstack compute service list --service nova-compute

image_1d8nfkkbvfh51ubt1e9rh3a1mnf4u.png-46.5kB

  1. 手动将新的计算节点添加到openstack集群
  3. su -s /bin/sh -c "nova-manage cell_v2 discover_hosts --verbose" nova

image_1d8nfolso3il19dh1ojchjb1gi45b.png-46.9kB

  1. 设置新创建节点自动注册的任务（已经添加到配置文件中）
  3. vim /etc/nova/nova.conf
  4. ---
  5. [scheduler]
  6. discover_hosts_in_cells_interval = 300
  7. ---
  8. 至此，计算节点安装完毕，接下来需要进行测试，检查nova节点的状态

1.8 在控制节点进行验证

  1. 参考文章：https://docs.openstack.org/nova/rocky/install/compute-install-rdo.html
  3. 1）应用管理员环境变量脚本
  4. cd /openstack
  5. source keystone-admin-pass.sh 
  6. 2）列表查看安装的nova服务组件
  7. # 验证是否成功注册并启动了每个进程
  9. openstack compute service list

image_1d8nfusgc148eq1g3481bopn4u5o.png-117.8kB

  1. 在身份认证服务中列出API端点以验证其连接性
  3. openstack catalog list

image_1d8ng0dn51gsa1r62gsk299e1m65.png-147.2kB

  1. 在镜像服务中列出已有镜像已检查镜像服务的连接性
  2. openstack image list

image_1d8ng1j2kbmo176fji37fe1ec6i.png-27.7kB

  1. 检查nova各组件的状态
  3. 检查placement API和cell服务是否正常工作
  5. nova-status upgrade check

image_1d8ng3s78fbd18l2117g1qutcfm7f.png-116.5kB

  1. 至此，nova计算节点，安装完毕并添加到openstack集群中
