该文根据openstack官方文档配置

0x01. Install and configure controller node (在控制节点安装配置一下内容)
一) 配置基本环境
1. 首先创建数据
[root@controller ~]# mysql -uroot -p MariaDB [(none)]> CREATE DATABASE nova; MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' -> IDENTIFIED BY 'NOVA_DBPASS'; MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' -> IDENTIFIED BY 'NOVA_DBPASS';
2. 加载环境变量:
[root@controller ~]# source admin-openrc.sh
3. 创建服务认证帐户:
[root@controller ~]# keystone user-create --name nova --pass NOVA_PASS
[root@controller ~]# keystone service-create --name nova --type compute -description "OpenStack Compute"
4. 创建一个供计算节点访问的api:
[root@controller ~]# keystone endpoint-create --service-id $(keystone service-list | awk '/ compute / {print $2}') --publicurl http://controller:8774/v2/%(tenant_id)s --internalurl http://controller:8774/v2/%(tenant_id)s --adminurl http://controller:8774/v2/%(tenant_id)s --region regionOne
二) 在控制节点安装配置计算组件
1. 安装所需软件包:
[root@controller ~]# yum install -y openstack-nova-api openstack-nova-cert openstack-nova-conductor openstack-nova-console openstack-nova-novncproxy openstack-nova-scheduler python-novaclient
2. 编辑 /etc/nova/nova.conf 文件
[root@controller ~]# cp /etc/nova/nova.conf /etc/nova/nova.conf.old [root@controller ~]# vi /etc/nova/nova.conf [database] connection = mysql://nova:NOVA_DBPASS@controller/nova [DEFAULT] rpc_backend = rabbit rabbit_host = controller rabbit_password = RABBIT_PASS auth_strategy = keystone my_ip = 192.168.88.133 vncserver_listen = 192.168.88.133 vncserver_proxyclient_address = 192.168.88.133 verbose = True [keystone_authtoken] auth_uri = http://controller:5000/v2.0 identity_uri = http://controller:35357 admin_tenant_name = service admin_user = nova admin_password = NOVA_PASS [glance] host = controller 3. Populate the Compute database: [root@controller ~]# su -s /bin/sh -c "nova-manage db sync" nova
三) 启动服务,完成以控制节点安装
[root@controller ~]# 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 [root@controller ~]# systemctl start openstack-nova-api.service openstack-nova-cert.service openstack-nova-consoleauth.service openstack-nova-scheduler.service openstack-nova-conductor.service openstack-nova-novncproxy.service
0x02.安装配置计算节点
一) 安装配置计算节点管理组件
1. 安装所需软件包:
[root@compute1 ~]# yum install -y openstack-nova-compute sysfsutils
2. 编辑 /etc/nova/nova.conf 文件,添加以下内容
[root@compute1 ~]# cp /etc/nova/nova.conf /etc/nova/nova.conf.old [root@compute1 ~]# vi /etc/nova/nova.conf [DEFAULT] rpc_backend = rabbit rabbit_host = controller rabbit_password = RABBIT_PASS auth_strategy = keystone my_ip = 192.168.88.135 vnc_enabled = True vncserver_listen = 0.0.0.0 vncserver_proxyclient_address = 192.168.88.135 novncproxy_base_url = http://controller:6080/vnc_auto.html verbose = True [keystone_authtoken] auth_uri = http://controller:5000/v2.0 identity_uri = http://controller:35357 admin_tenant_name = service admin_user = nova admin_password = NOVA_PASS [glance] host = controller
二) 安装完成并启动服务
[root@compute1 ~]# egrep -c '(vmx|svm)' /proc/cpuinfo [root@compute1 ~]# vi /etc/nova/nova.conf [libvirt] virt_type = qemu [root@compute1 ~]# systemctl enable libvirtd.service openstack-nova-compute.service [root@compute1 ~]# systemctl start libvirtd.service openstack-nova-compute.service
##### 这里查看状态时报错 #####
[root@compute1 ~]# systemctl status libvirtd.service openstack-nova-compute.service
# error:Module /usr/lib64/libvirt/connection-driver/libvirt_driver_lxc.so not accessible
# 通过以下安装可以解决
[root@compute1 ~]# yum update -y device-mapper
0x03.确认以上操作
1. 在控制节点执行,加载环境变量:
[root@controller ~]# source admin-openrc.sh
2. 显示组建注册是否成功:
[root@controller ~]# nova service-list
3. 列出上传的镜像与状态:
[root@controller ~]# nova image-list
