二.OpenStack概述
OpenStack项目是一个开源云计算平台，支持全部类型的云环境。该项目旨在实现简单，大规模的可扩展性和丰富的功能。数据库
OpenStack经过各类补充服务提供基础架构即服务（IaaS）解决方案。每项服务都提供了一个应用程序编程接口（API），以促进这种集成。apache
本文涵盖了使用适用于具备足够Linux经验的OpenStack新用户的功能性示例体系结构，逐步部署主要OpenStack服务。只用于学习OpenStack最小化环境。
3、OpenStack架构总览
1.概念性架构
下图显示了OpenStack服务之间的关系：
2.逻辑体系结构
下图显示了OpenStack云中最多见但不是惟一可能的体系结构：
对于设计，部署和配置OpenStack，学习者必须了解逻辑体系结构。
如概念架构所示，OpenStack由几个独立的部分组成，称为OpenStack服务。全部服务都经过keystone服务进行身份验证。
各个服务经过公共API相互交互，除非须要特权管理员命令。
在内部，OpenStack服务由多个进程组成。全部服务都至少有一个API进程，它监听API请求，预处理它们并将它们传递给服务的其余部分。除身份服务外，实际工做由不一样的流程完成。
对于一个服务的进程之间的通讯，使用AMQP消息代理。该服务的状态存储在数据库中。部署和配置OpenStack云时，您能够选择多种消息代理和数据库解决方案，例如RabbitMQ，MySQL，MariaDB和SQLite。
用户能够经过Horizon Dashboard实现的基于Web的用户界面，经过命令行客户端以及经过浏览器插件或curl等工具发布API请求来访问OpenStack。对于应用程序，有几个SDK可用。最终，全部这些访问方法都会对各类OpenStack服务发出REST API调用。
四.OpenStack组件服务部署
部署前置条件（如下命令在全部节点执行）
1.配置节点网卡IP（略）
2.设置主机名
hostnamectl set-hostname 主机名 bash ##使设置当即生效
3.配置域名解析，编辑编辑/etc/hosts文件，加入以下配置
10.71.11.12 controller 10.71.11.13 compute 10.71.11.14 cinder
4.验证网络连通性
在控制节点执行
root@controller ~]# ping -c 4 openstack.org PING openstack.org (162.242.140.107) 56(84) bytes of data. 64 bytes from 162.242.140.107 (162.242.140.107): icmp_seq=1 ttl=46 time=248 ms 64 bytes from 162.242.140.107 (162.242.140.107): icmp_seq=2 ttl=46 time=248 ms 64 bytes from 162.242.140.107 (162.242.140.107): icmp_seq=3 ttl=46 time=248 ms 64 bytes from 162.242.140.107 (162.242.140.107): icmp_seq=4 ttl=46 time=248 ms [root@controller ~]# ping -c 4 compute PING compute (10.71.11.13) 56(84) bytes of data. 64 bytes from compute (10.71.11.13): icmp_seq=1 ttl=64 time=0.395 ms 64 bytes from compute (10.71.11.13): icmp_seq=2 ttl=64 time=0.214 ms

注意：平常运维中常常碰见时钟飘逸问题，致使集群服务脑裂
openstack服务安装、配置
说明：无特殊说明，如下操做在全部节点上执行
1.下载安装openstack软件仓库（queens版本）
yum install centos-release-openstack-queens -y
2.更新全部节点软件包
yum upgrade
3.安装openstack client端
yum install python-openstackclient -y
4.安装openstack-selinux
yum install openstack-selinux -y
安装数据库（controller节点执行）
大多数OpenStack服务使用SQL数据库来存储信息，数据库一般在控制器节点上运行。 本文主要使用MariaDB或MySQL。
安装软件包
yum install mariadb mariadb-server python2-PyMySQL -y
编辑/etc/my.cnf.d/mariadb-server.cnf并完成如下操做
[root@controller ~]# vi /etc/my.cnf.d/mariadb-server.cnf # # These groups are read by MariaDB server. # Use it for options that only the server (but not clients) should see # # See the examples of server my.cnf files in /usr/share/mysql/ # # this is read by the standalone daemon and embedded servers [server] # this is only for the mysqld standalone daemon # Settings user and group are ignored when systemd is used. # If you need to run mysqld under a different user or group, # customize your systemd unit file for mysqld/mariadb according to the # instructions in http://fedoraproject.org/wiki/Systemd [mysqld] datadir=/var/lib/mysql socket=/var/lib/mysql/mysql.sock log-error=/var/log/mariadb/mariadb.log pid-file=/var/run/mariadb/mariadb.pid bind-address = 10.71.11.12 default-storage-engine = innodb innodb_file_per_table = on max_connections = 4096 collation-server = utf8_general_ci character-set-server = utf8
说明：bind-address使用controller节点的管理IP
设置服务开机启动
systemctl enable mariadb.service systemctl start mariadb.service
经过运行mysql_secure_installation脚原本保护数据库服务。
[root@controller ~]# mysql_secure_installation
NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!
In order to log into MariaDB to secure it, we'll need the current
password for the root user. If you've just installed MariaDB, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.
Enter current password for root (enter for none):
OK, successfully used password, moving on...
Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.
Set root password? [Y/n]
New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..
... Success!
By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them. This is intended only for testing, and to make the installation
go a bit smoother. You should remove them before moving into a
production environment.
Remove anonymous users? [Y/n]
... Success!
Normally, root should only be allowed to connect from 'localhost'. This
ensures that someone cannot guess at the root password from the network.
Disallow root login remotely? [Y/n]
... Success!
By default, MariaDB comes with a database named 'test' that anyone can
access. This is also intended only for testing, and should be removed
before moving into a production environment.
Remove test database and access to it? [Y/n]
- Dropping test database...
... Success!
- Removing privileges on test database...
... Success!
Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.
Reload privilege tables now? [Y/n]
... Success!
Cleaning up...
All done! If you've completed all of the above steps, your MariaDB
installation should now be secure.
Thanks for using MariaDB!

通过判断，是SELinux引起的问题
解决办法：关闭防火墙
[root@controller ~]# vi /etc/selinux/config # This file controls the state of SELinux on the system. # SELINUX= can take one of these three values: # enforcing - SELinux security policy is enforced. # permissive - SELinux prints warnings instead of enforcing. # disabled - No SELinux policy is loaded. SELINUX=disabled # SELINUXTYPE= can take one of three two values: # targeted - Targeted processes are protected, # minimum - Modification of targeted policy. Only selected processes are protected. # mls - Multi Level Security protection. SELINUXTYPE=targeted
再次重启服务报错解决
[root@controller ~]# systemctl enable httpd.service;systemctl start httpd.service
4.配置administrative帐号
export OS_USERNAME=admin export OS_PASSWORD=123456 export OS_PROJECT_NAME=admin export OS_USER_DOMAIN_NAME=Default export OS_PROJECT_DOMAIN_NAME=Default export OS_AUTH_URL=http://controller:35357/v3 export OS_IDENTITY_API_VERSION=3

安装和配置Cinder节点
本节介绍如何为Block Storage服务安装和配置存储节点。 为简单起见，此配置使用空的本地块存储设备引用一个存储节点。
该服务使用LVM驱动程序在该设备上配置逻辑卷，并经过iSCSI传输将其提供给实例。 您能够按照这些说明进行小的修改，以便使用其余存储节点水平扩展您的环境。
1.安装支持的软件包
安装LVM
yum install lvm2 device-mapper-persistent-data
设置LVM服务开机启动
systemctl enable lvm2-lvmetad.service systemctl start lvm2-lvmetad.service
2.建立LVM物理逻辑卷/dev/sdb
[root@cinder ~]# pvcreate /dev/sdb1 Device /dev/sdb not found (or ignored by filtering).
解决方案：
编辑 vim /etc/lvm/lvm.conf,找到global_filter一行，配置以下
global_filter = [ "a|.*/|","a|sdb1|"]
以后再执行pvcreate命令，问题解决。
[root@cinder ~]# pvcreate /dev/sdb1 Physical volume "/dev/sdb1" successfully created.
3.建立cinder-volumes逻辑卷组
[root@cinder ~]# vgcreate cinder-volumes /dev/sdb1 Volume group "cinder-volumes" successfully created
4.安装和配置组件
安装软件包
yum install openstack-cinder targetcli python-keystone -y
编辑/etc/cinder/cinder.conf
[DEFAULT] transport_url = rabbit://openstack:123456@controller auth_strategy = keystone my_ip = 10.71.11.14 enabled_backends = lvm glance_api_servers = http://controller:9292 [database] connection = mysql+pymysql://cinder:123456@controller/cinder [keystone_authtoken] auth_uri = http://controller:5000 auth_url = http://controller:35357 memcached_servers = controller:11211 auth_type = password project_domain_id = default user_domain_id = default project_name = service username = cinder password = 123456 在[lvm]部分中，使用LVM驱动程序，cinder-volumes卷组，iSCSI协议和相应的iSCSI服务配置LVM后端。 若是[lvm]部分不存在，请建立它： [lvm] volume_driver = cinder.volume.drivers.lvm.LVMVolumeDriver volume_group = cinder-volumes iscsi_protocol = iscsi iscsi_helper = lioadm [oslo_concurrency] lock_path = /var/lib/cinder/tmp
设置存储服务开机启动
systemctl enable openstack-cinder-volume.service target.service systemctl start openstack-cinder-volume.service target.service
5、登陆Dashboard界面
社区Queens Web界面显示三个角色
- 项目
- 管理员
- 身份管理
6、命令行上传镜像
1. 把原生iso镜像上传到controller节点
2.转换原生ISO镜像格式为qcow2
[root@controller ~]# openstack image create --disk-format qcow2 --container-format bare --public --file /root/CentOS-7-x86_64-Minimal-1708.iso CentOS-7-x86_64
3.查看制做的镜像信息
7、建立虚拟机流程
1. 建立网络
. admin-openrc openstack network create --share --external --provider-physical-network provider --provider-network-type flat provider
参数
--share 容许全部项目使用虚拟网络
--external 定义外接虚拟网络 若是须要建立外网使用 --internal
--provider-physical-network provider && --provider-network-type flat 链接flat 虚拟网络
2.建立子网
openstack subnet create --network provider --allocation-pool start=10.71.11.50,end=10.71.11.60 --dns-nameserver 114.114.114.114 --gateway 10.71.11.254 --subnet-range 10.71.11.0/24 provider
3.建立flavor
openstack flavor create --id 1 --vcpus 4 --ram 128 --disk 1 m2.nano
4.控制节点生成秘钥对,在启动实例以前，须要将公钥添加到Compute服务
. demo-openrc ssh-keygen -q -N "" openstack keypair create --public-key ~/.ssh/id_rsa.pub liukey
5.添加安全组，容许ICMP（ping）和安全shell（SSH）
openstack security group rule create --proto icmp default
6.容许安全shell（SSH）访问
openstack security group rule create --proto tcp --dst-port 22 default
7.列出flavor
openstack flavor list
8.列出可用镜像
9.列出网络
10.列出安全组
11.建立虚拟机
12.查看实列状态
