私有云搭建步骤

随着云计算技术的不断发展，越来越多的企业和个人用户开始关注私有云的搭建与应用，私有云具有安全性高、成本可控、灵活性强等优点，能够为企业提供高效、稳定的计算和存储服务，本文将详细介绍如何在openSUSE环境下搭建私有云。

openSUSE简介

openSUSE是一款基于Linux的开源操作系统，它拥有强大的社区支持，提供了丰富的软件仓库，可以满足用户的各种需求，openSUSE具有良好的稳定性、安全性和可扩展性，是搭建私有云的理想选择。

私有云搭建所需软件及工具

1、openSUSE Leap版本（建议使用最新版本）

2、OpenStack（开源云计算平台）

3、KVM（虚拟化技术）

4、Libvirt（管理虚拟机的库和工具）

5、MySQL（数据库）

6、RabbitMQ（消息队列）

7、Apache或Nginx（Web服务器）

8、Keystone（身份认证服务）

9、Glance（镜像服务）

10、Cinder（块存储服务）

11、Neutron（网络服务）

12、Nova（计算服务）

私有云搭建步骤

1、安装openSUSE Leap

在服务器上安装openSUSE Leap操作系统，可以从openSUSE官网下载最新版本的ISO文件，并通过CD/DVD或USB启动盘进行安装。

2、安装OpenStack

在openSUSE Leap系统上安装OpenStack，可以使用以下命令安装OpenStack：

sudo zypper install openstack-keystone openstack-glance openstack-nova openstack-neutron openstack-cinder

3、配置数据库

安装MySQL数据库，并创建相应的数据库和用户：

sudo zypper install mysql-community-server
sudo systemctl start mysqld
sudo mysql_secure_installation

创建数据库和用户：

mysql -u root -p
CREATE DATABASE keystone;
CREATE DATABASE glance;
CREATE DATABASE nova;
CREATE DATABASE neutron;
CREATE DATABASE cinder;
CREATE USER 'keystone'@'localhost' IDENTIFIED BY 'password';
CREATE USER 'glance'@'localhost' IDENTIFIED BY 'password';
CREATE USER 'nova'@'localhost' IDENTIFIED BY 'password';
CREATE USER 'neutron'@'localhost' IDENTIFIED BY 'password';
CREATE USER 'cinder'@'localhost' IDENTIFIED BY 'password';
GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'localhost';
GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'localhost';
GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost';
GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'localhost';
GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'localhost';
FLUSH PRIVILEGES;
EXIT;

4、配置RabbitMQ

安装RabbitMQ，并创建用户和虚拟主机：

sudo zypper install rabbitmq-server
sudo systemctl start rabbitmq-server
sudo rabbitmqctl add_user openstack password
sudo rabbitmqctl set_permissions openstack ".*" ".*" ".*"
sudo rabbitmqctl add_vhost openstack

5、配置Keystone

编辑/etc/keystone/keystone.conf文件，配置数据库连接和RabbitMQ连接：

[database]
connection = mysql+pymysql://keystone:password@localhost/keystone
[uppercase]
[profiler]
[cache]
[session]
[revoke]
[fernet]
[keycloak]
[assignment]
[identity]
[shadow_user]
[domain]
[federation]
[notification]
[resource]
[role]
[service]
[endpoint_filter]
[role_domain]
[identity_mapping]
[ec2]
[oauth2]
[swift]
[trust]
[ks mop]
[ks-meta]
[ks Venom]
[ks tokens]
[ks endpoints]
[ks simple_cert]
[ks password]
[ks fernet_tokens]
[ks bootstrap]
[ks identity]
[ks assignment]
[ks catalog]
[ks endpoint_filter]
[ks domain]
[ks role]
[ks user]
[ks service]
[ks policy]
[ks token]
[ks resource]

[ks ks password]
[ks ks fernet_tokens]
[ks ks bootstrap]
[ks ks identity]
[ks ks assignment]
[ks ks catalog]
[ks ks endpoint_filter]
[ks ks domain]
[ks ks role]
[ks ks user]
[ks ks service]
[ks ks policy]
[ks ks token]
[ks ks resource]
[ks ks trust]
[ks ks credential]
[ks ks auth]
[ks ks endpoint]
[ks ks role_domain]
[ks ks identity_mapping]
[ks ks federation]
[ks ks ec2]
[ks ks oauth2]
[ks ks swift]
[ks ks trust]
[trust:backend]
engine = sql
driver =keystone.db.sqlalchemy.driver
[trust:bootstrap]
role_name = trustee

6、同步Keystone数据库：

sudo su -s /bin/sh -c "keystone-manage db_sync" keystone

7、配置Glance

编辑/etc/glance/glance-api.conf和/etc/glance/glance-registry.conf文件，配置数据库连接和RabbitMQ连接：

[database]
connection = mysql+pymysql://glance:password@localhost/glance
[keystone_authtoken]
auth_uri = http://localhost:5000/v3
auth_url = http://localhost:35357/v3
memcached_servers = localhost:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = glance
password = password
[glance_store]
