openstack
私有云搭建
实验环境：rhel7.2
禁用或移除所有自动更新的服务，因为它们会影响到您的 OpenStack 环境。
systemctl stop NetworkManager
systemctl disable NetworkManager
独立节点的配置
1.添加网卡
2.更改配置文件
DEVICE="ens9"
ONBOOT=yes
BOOTPROTO=none3.重启服务
vim /boot/grub2/grub.cfg
在内核引导文件中添加这个net.ifnames=0（99行）就可以添加网卡之后默认显示的是eth*
一、网络时间的同步；
物理机同步其他时间，虚拟机同步物理机时间

（将openstack的包放到yum仓库中【/var/www/html】）
[root@open1 yum.repos.d]# vim yum.repo
事先准备好自己所要的包，放到http的默认发布目录下：
[openstack]
name=mitaka
baseurl=http://172.25.39.250/mitaka
gpgcheck=0
enabled=1三、openstack环境的部署
控制节点的部署：
1）openstack包的安装
所有节点上执行这些程序
yum upgrade—在主机上升级包(如果更新了一个新内核，重启主机来使用新内核)
yum install python-openstackclient -y—安装 OpenStack 客户端
2)SQL数据库
大多数 OpenStack 服务使用 SQL 数据库来存储信息。 典型地，数据库运行在控制节点上。
yum install mariadb mariadb-server python2-PyMySQL—安装软件包
创建并编辑 /etc/my.cnf.d/openstack.cnf，然后完成如下动作：
在[mysqld]部分，设置 bind-address值为控制节点的管理网络IP地址以使得其它节点可以通过管理网络访问数据库：
在[mysqld]部分，设置如下键值来启用一起有用的选项和 UTF-8 字符集：
[root@open1 yum.repos.d]# vim /etc/my.cnf.d/openstack.cnf
[mysqld]
bind-address = 172.25.39.1
default-storage-engine = innodb-指定存储引擎
innodb_file_per_table----独立表空间
max_connections = 4096----最大连接数
collation-server = utf8_general_ci
character-set-server = utf8启动数据库服务，并将其配置为开机自启
[root@open1 yum.repos.d]# systemctl enable mariadb.service
Created symlink from /etc/systemd/system/multi-user.target.wants/mariadb.service to /usr/lib/systemd/system/mariadb.service.
[root@open1 yum.repos.d]# systemctl start mariadb.service
初始化：
[root@open1 yum.repos.d]# mysql_secure_installation
NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDBSERVERS 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![root@open1 yum.repos.d]# mysql -pwestos

OpenStack 使用 message queue 协调操作和各服务的状态信息。消息队列服务一般运行在控制节点上。OpenStack支持好几种消息队列服务包括 RabbitMQ, Qpid, 和 ZeroMQ。
yum install rabbitmq-server
systemctl enable rabbitmq-server.service
systemctl start rabbitmq-server.service
添加 openstack 用户：
rabbitmqctl add_user openstack westos
给openstack用户配置写和读权限：
rabbitmqctl set_permissions openstack ".*" ".*" ".*"[root@open1 network-scripts]# rabbitmq-plugins enable rabbitmq_management--------管理工具的开启
The following plugins have been enabled:mochiwebwebmachinerabbitmq_web_dispatchamqp_clientrabbitmq_management_agentrabbitmq_managementApplying plugin configuration to rabbit@open1... started 6 plugins
根据上述显示，与之依赖的也会被打开netstat -antlp（发现15672打开）
tcp 0 0 0.0.0.0:15672 0.0.0.0:* LISTEN 2293/beam
这个时候在浏览器，会出现RabbitMQ界面
http://172.25.39.1:15672/
登陆：用户、密码均为guest
[root@open1 network-scripts]# cat /etc/hosts—一定要解析
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
172.25.39.1 open1
172.25.39.2 open2
用户的查看: rabbitmqctl list_users
[root@open1 network-scripts]# rabbitmqctl list_users
Listing users ...
openstack []
guest [administrator]openstack的权限的查看
[root@open1 network-scripts]# rabbitmqctl list_user_permissions openstack
Listing permissions for user "openstack" ...

[root@open1 network-scripts]# rabbitmqctl authenticate_user openstack openstack
Authenticating user "openstack" ...
Error: failed to authenticate user "openstack"
[root@open1 network-scripts]# rabbitmqctl authenticate_user openstack westos
Authenticating user "openstack" ...
Success4）memcached
认证服务认证缓存使用Memcached缓存令牌。缓存服务memecached运行在控制节点。
yum install memcached python-memcached
systemctl enable memcached.service
systemctl start memcached.service
[root@open1 network-scripts]# netstat -antlp
tcp 0 0 127.0.0.1:11211 0.0.0.0:* LISTEN 3847/memcached
监听地址的更改：vim /etc/sysconfig/memcached 1 PORT="11211"2 USER="memcached"3 MAXCONN="1024"4 CACHESIZE="64"5 OPTIONS="-l 127.0.0.1,::1,172.25.39.1"这个时候就会发现监听了设置ip的主机
[root@open1 network-scripts]# netstat -antlp

tcp 0 0 127.0.0.1:11211 0.0.0.0:* LISTEN 3890/memcached 四、认证服务(提供用户认证和服务目录，服务目录记录了所有云计算的api端口)
OpenStack:term:Identity service为认证管理，授权管理和服务目录服务管理提供单点整合。
身份认证服务提供服务的目录和他们的位置。每个你添加到OpenStack环境中的服务在目录中需要一个 service 实体和一些 API endpoints 。
安全并配置组件
[root@open1 network-scripts]# yum install openstack-keystone httpd mod_wsgi -y
[root@open1 network-scripts]# openssl rand -hex 10---生成admin token
e185f1e79b487c6eb9aa（m版的api默认放到memcache，可以定义过期自动删除的token）[root@open1 conf.d]# vim /etc/keystone/keystone.conf
在[DEFAULT]部分，定义初始管理令牌的值：3 admin_token = e185f1e79b487c6eb9aa在[database]部分，配置数据库访问528 [database]529 connection = mysql+pymysql://keystone:westos@172.25.39.1/keys tone在[token]部分，配置Fernet UUID令牌的提供者。
1986 [token]
1987 provider = fernet初始化身份认证服务的数据库(同步数据库)：
[root@open1 conf.d]# su -s /bin/sh -c "keystone-manage db_sync" keystone
（指定shell，用keystone的身份执行指令：keystone-manage db_sync）验证：
[root@open1 conf.d]# mysql -pwestos

+------------+------------------------------------------------------------------------九、创建 OpenStack 客户端环境脚本
为了提升客户端操作的效率，OpenStack支持简单的客户端环境变量脚本即OpenRC 文件。
创建admin项目和用户创建客户端环境变量脚本
[root@open1 keystone]# vim admin-openrc
[root@open1 keystone]# cat admin-openrc
export OS_PROJECT_DOMAIN_NAME=default
export OS_USER_DOMAIN_NAME=default
export OS_PROJECT_NAME=admin
export OS_USERNAME=admin
export OS_PASSWORD=westos
export OS_AUTH_URL=http://172.25.39.1:35357/v3
export OS_IDENTITY_API_VERSION=3
export OS_IMAGE_API_VERSION=2创建demo项目和用户创建客户端环境变量脚本
[root@open1 keystone]# vim demo-openrc
[root@open1 keystone]# cat demo-openrc
export OS_PROJECT_DOMAIN_NAME=default
export OS_USER_DOMAIN_NAME=default
export OS_PROJECT_NAME=demo
export OS_USERNAME=demo
export OS_PASSWORD=westos
export OS_AUTH_URL=http://172.25.39.1:5000/v3
export OS_IDENTITY_API_VERSION=3
export OS_IMAGE_API_VERSION=2[root@open1 keystone]# chmod +x admin-openrc
[root@open1 keystone]# chmod +x demo-openrc
脚本的使用：
加载admin-openrc文件来身份认证服务的环境变量位置和admin项目和用户证书：
[root@open1 keystone]# . admin-openrc
[root@open1 keystone]# source admin-openrc
[root@open1 keystone]# openstack user list
+----------------------------------+-------+
| ID | Name |
+----------------------------------+-------+
| 33a3c544d28c4c3bb8cb1291d224e7b2 | demo |
| d27c9e220e24407dad0d68ef8b5b6dd1 | admin |
+----------------------------------+-------+请求认证令牌:
[root@open1 keystone]# openstack token issue
+------------+---------------------------------------------------+
| Field | Value |
+------------+---------------------------------------------------+
| expires | 2017-08-15T07:56:53.860553Z |

| user_id | d27c9e220e24407dad0d68ef8b5b6dd1 |
+------------+---------------------------------------------------+这个时候使用不同的用户就可以发现权限不同：
[root@open1 keystone]# source demo-openrc
[root@open1 keystone]# openstack user list
You are not authorized to perform the requested action: identity:list_users (HTTP 403) (Request-ID: req-39074f7f-fad3-48b1-9d0e-4a3de732cab2)
[root@open1 keystone]# source admin-openrc
[root@open1 keystone]# openstack user list
+----------------------------------+-------+
| ID | Name |
+----------------------------------+-------+
| 33a3c544d28c4c3bb8cb1291d224e7b2 | demo |
| d27c9e220e24407dad0d68ef8b5b6dd1 | admin |
+----------------------------------+-------+十、安装与配置
安全并配置组件
安装软件包：
[root@open1 ~]# yum install openstack-glance
[root@open1 ~]# vim /etc/glance/glance-api.conf
在 [database] 部分，配置数据库访问：
[database]
connection = mysql+pymysql://glance:westos@172.25.39.1/glance在 [keystone_authtoken] 和 [paste_deploy] 部分，配置认证服务访问：[keystone_authtoken]
auth_uri = http://172.25.39.1:5000
auth_url = http://172.25.39.1:35357
memcached_servers = 172.25.39.1:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = glance
password = westos[paste_deploy]
flavor = keystone在 [glance_store] 部分，配置本地文件系统存储和镜像文件位置：
[glance_store]
stores = file,http
default_store = file
filesystem_store_datadir = /var/lib/glance/images/[root@open1 ~]# vim /etc/glance/glance-registry.conf
在[database] 部分，配置数据库访问：
[database]
connection = mysql+pymysql://glance:westos@172.25.39.1/glance在 [keystone_authtoken] 和 [paste_deploy] 部分，配置认证服务访问：
[keystone_authtoken]
auth_uri = http://172.25.39.1:5000
auth_url = http://172.25.39.1:35357
memcached_servers = 172.25.39.1:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = glance
password = westos[paste_deploy]
flavor = keystone写入镜像服务数据库：
[root@open1 ~]# su -s /bin/sh -c “glance-manage db_sync” glance
