openstack集群部署详细操作步骤，部署openstack过程中核心组件（openstack集群架构）

OpenStack集群部署详细操作步骤

1、准备工作

在部署OpenStack之前，需要确保以下硬件和软件环境已经准备就绪：

– 至少3台服务器，每台服务器至少2GB内存，建议使用4核CPU。

– 至少1台服务器具有千兆网卡，以便连接外部网络。

– 操作系统：RHEL/CentOS 6.5、Ubuntu 12.04或更高版本。

– 网络：至少1台服务器具有IPv4地址，所有服务器之间可以通过内网互相访问。

– 存储：至少1台服务器具有足够的磁盘空间，用于存储OpenStack镜像、配置文件和数据卷。

2、安装并配置KVM虚拟化平台

在所有服务器上安装KVM虚拟化平台，以便创建和管理虚拟机，在RHEL/CentOS上，可以使用以下命令安装QEMU和KVM:

sudo yum install qemu-kvm libvirt libvirt-python libguestfs-tools virt-install virt-manager

在Ubuntu上，可以使用以下命令安装QEMU和KVM:

sudo apt-get install qemu-kvm libvirt-bin libvirt-daemon-system libvirt-clients bridge-utils virtinst virt-manager

3、安装并配置OpenStack组件

在所有服务器上安装OpenStack组件，包括计算、网络、存储和认证服务，以下是安装OpenStack组件的命令示例：

sudo yum install openstack-nova openstack-nova-api openstack-nova-conductor openstack-nova-consoleauth openstack-nova-novncproxy openstack-nova-scheduler openstack-nova-placement openstack-neutron neutron-server neutron-plugin-ml2 neutron-linuxbridge-agent neutron-dhcp-agent neutron-metadata-agent neutron-l3agent neutron-l3router tenant-network-ingress neutron-netfilter-noop tenant-networking-features keystone apache httpd mysql-server php php-mysql python-mysqldb python-memcached python-keystoneclient python-glanceclient python-novaclient python-cinderclient python-swiftclient python-heatclient python-openstackclient git

4、配置OpenStack组件

根据实际需求，编辑各个OpenStack组件的配置文件，可以修改以下配置文件以启用数据库认证方式为密码认证：

[DEFAULT]
...
database = mysql+pymysql://openstack:openstack@controller/nova?charset=utf8mb4&parse_sql=True&sql_mode=NO_ENGINE_SUBSTITUTION

5、启动并设置开机自启动的服务

启动各个OpenStack组件，并将它们设置为开机自启动，可以使用以下命令启动各个服务：

sudo systemctl start openstack-nova openstack-nova-api openstack-nova-conductor openstack-nova-consoleauth openstack-nova-novncproxy openstack-nova-scheduler openstack-nova-placement openstack-neutron
