要确保*标出现，才代表与时间服务器同步完成。
2. 软件包准备
- 安装OpenStack Pike Repository
~]# yum install centos-release-openstack-pike -y - 升级软件包
~]# yum upgrade - 安装openstack客户端软件包
~]# yum install python-openstackclient -y - 安装openstack-selinux软件包
~]# yum install openstack-selinux -y
3. 数据库准备
- 安装软件包
~]# yum -y install mariadb mariadb-server python2-PyMySQL - 编辑配置文件
~]# vim /etc/my.cnf.d/openstack.cnf
[mysqld]
bind-address = 10.6.10.1 # Controller节点的管理IP
default-storage-engine = innodb
innodb_file_per_table = on
max_connections = 4096
collation-server = utf8_general_ci
character-set-server = utf8
- 启动mariadb服务，并配置成开机自动启动
~]# systemctl enable mariadb.service
~]# systemctl start mariadb.service - 为mariadb执行安全脚本，并设定数据库root用户密码为pike
~]# 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] Y
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] Y
... 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] Y
... 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] Y
- 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] Y
... 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!
4. RabbitMQ准备
- 安装软件包
~]# yum -y install rabbitmq-server - 启动服务，并配置成开机自动启动

二、 Keystone的安装及配置
1. 前期准备
(1) 使用root用户登录mysql数据库
~]# mysql -u root -p
(2) 创建keystone数据库
MariaDB [(none)]> CREATE DATABASE keystone;
(3) 为keystone数据库创建账号并授权相关权限
MariaDB [(none)]> GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'localhost' \ IDENTIFIED BY 'pike';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%' \ IDENTIFIED BY 'pike';
2. 安装和配置组件
(1) 安装软件包
~]# yum -y install openstack-keystone httpd mod_wsgi
(2) 编辑配置文件

~]# vim /etc/keystone/keystone.conf
[database]
...
connection = mysql+pymysql://keystone:pike@controller/keystone
[token]
...
provider = fernet
(3) 迁移数据库，使用keystone用户登录/bin/sh，并执行迁移数据库命令
~]# su -s /bin/sh -c "keystone-manage db_sync" keystone
此时，MySQL数据库中，可以查到keystone数据库已经有很多表了。
(4) 验证数据库操作是否完成
~]# mysql -u root -p
MariaDB [(none)]> USE keystone;
MariaDB [keystone]> SHOW TABLES;
如果能够看到已经存在很多表，说明数据库操作成功执行了。
(5) 初始化Fernet Key Repository
~]# keystone-manage fernet_setup --keystone-user keystone --keystone-group keystone
~]# keystone-manage credential_setup --keystone-user keystone --keystone-group keystone
(6) Bootstrap the Identity Service
~]# keystone-manage bootstrap --bootstrap-password pike \ --bootstrap-admin-url http://controller:35357/v3/ \ --bootstrap-internal-url http://controller:5000/v3/ \ --bootstrap-public-url http://controller:5000/v3/ \ --bootstrap-region-id RegionOne
3. 配置Apache HTTP Server
(1) 编辑配置文件
~]# cp /etc/httpd/conf/httpd.conf{,.bak}
~]# vim /etc/httpd/conf/httpd.conf
ServerName controller

$ 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
5. 创建域、项目、用户和角色
(1) 创建service项目
~]# openstack project create --domain default \
--description "Service Project" service
+-------------+----------------------------------+
| Field | Value |
+-------------+----------------------------------+
| description | Service Project |
| domain_id | default |
| enabled | True |
| id | 04a94172e964433b82be58b94dcc4ad0 |
| is_domain | False |
| name | service |
| parent_id | default |
+-------------+----------------------------------+
(2) 创建demo项目和demo用户
- 创建demo项目
~]# openstack project create --domain default \
--description "Demo Project" demo
+-------------+----------------------------------+
| Field | Value |
+-------------+----------------------------------+

| name | user |
+-----------+----------------------------------+
- 将user角色添加到demo项目和demo用户上
~]# openstack role add --project demo --user demo user
注意：
创建用户的操作可以重复进行，但是如果想在一个项目中创建多个用户，之前创建项目的操作不要按照手册重复进行。
6. 验证操作
(1) 出于安全考虑，禁用临时认证token
~]# cp /etc/keystone/keystone-paste.ini{,.bak}
~]# vim /etc/keystone/keystone-paste.ini
在[pipeline:public_api]、[pipeline:admin_api]、[pipeline:api_v3]三个部分删除其中admin_token_auth字段
(2) 取消设置的环境变量OS_AUTH_URL和OS_PASSWORD
~]# unset OS_AUTH_URL OS_PASSWORD
(3) 为admin用户申请一个认证token
~]# openstack --os-auth-url http://controller:35357/v3 \
> --os-project-domain-name Default --os-user-domain-name Default \
> --os-project-name admin --os-username admin token issue
Password:
+------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
| Field | Value |
+------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+

| user_id | 987e3ca1748d473d8d658f5f34d1ad39 |
+------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
7. 创建OpenStack客户端环境变量脚本
有时在客户端执行openstack的命令，会需要切换项目及用户（admin、demo），为了执行效率考虑，将各自用户需要的环境变量信息编辑成单独的文件，当需要使用某个用户的凭证进行后续操作时，直接读取该用户自己的环境变量脚本文件，省去了逐行设定环境变量的工作。
(1) 创建admin用户的环境变量脚本文件admin-openrc
~]# vim 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=pike
export OS_AUTH_URL=http://controller:35357/v3
export OS_IDENTITY_API_VERSION=3
export OS_IMAGE_API_VERSION=2
(2) 创建demo用户的环境变量脚本文件demo-openrc
~]# vim 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=pike
export OS_AUTH_URL=http://controller:5000/v3
export OS_IDENTITY_API_VERSION=3
export OS_IMAGE_API_VERSION=2
8. 使用环境变量脚本文件
(1) 使用admin-openrc文件来加载调用admin项目和用户
~]# . admin-openrc
(2) 请求凭证token
~]# openstack token issue
+------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
| Field | Value |
+------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
| expires | 2018-02-07T08:03:40+0000 |
| id | gAAAAABaeqTMLZZpqm1TE7LZ3-8YTerMSssI_wv7EJTZI9WtxRI7ARwjhDgDGBNx7vwGEkcI4BTWsg1SDFPlen5R5cvLdGLp3syODkoUfJT_lAvRnuOpjp6ZkAeojp_Vf3z3f4bJvd4Clg7tV1OCIFiabIRFjYzXLOiZ69VOS_-xiGW7B67t5xw |
| project_id | 63a7987395d54774b6045e2648d88a58 |
| user_id | 17b3d5190c444945a70ed31009f4fe24 |

七、Cinder的安装及配置
1. 前期准备
(1) 数据库准备
- 以root用户登录MariaDB数据库
~]# mysql -u root -p - 创建cinder数据库
MariaDB [(none)]> CREATE DATABASE cinder; - 创建用户并配置权限
MariaDB [(none)]> GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'localhost' IDENTIFIED BY 'pike';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'%' IDENTIFIED BY 'pike';
(2) 读取admin-openrc环境变量脚本文件
~]# . admin-openrc
(3) 创建服务凭证
- 创建cinder用户，并设置密码为pike
~]# openstack user create --domain default --password-prompt cinder
User Password:
Repeat User Password:

- 将self-service子网添加到路由器作为一个端口
~]# neutron router-interface-add router selfservice-172.20
neutron CLI is deprecated and will be removed in the future. Use openstack CLI instead.
Added interface d778a840-eb14-4b05-bf93-7675426bbbfa to router router.
- 在路由器上将provider网络的网关设定上
~]# neutron router-gateway-set router provider
neutron CLI is deprecated and will be removed in the future. Use openstack CLI instead.
Set gateway for router router
(4) 验证操作
该步骤在controller节点上操作
- 读取admin-openrc环境变量配置文件
~]# . admin-openrc - 列出网络名称空间，应该列出一个qrouter和两个qdhcp
~]# ip netns
qrouter-6f7ba61a-31d5-4db9-b480-c81f6fdc1db8 (id: 2)
qdhcp-732b888f-b4e9-4eae-ad82-c93b51a67080 (id: 1)
qdhcp-3c54c8fe-41b5-4691-aac4-ae6e2436cae2 (id: 0)
- 在路由器上列出在Provider网络的网关IP地址
~]# neutron router-port-list router
neutron CLI is deprecated and will be removed in the future. Use openstack CLI instead.

+--------------------------------------+------+----------------------------------+-------------------+------------------------------------------------------------------------------------+
- 在controller节点ping provider网络内的主机IP地址
~]# ping -c 4 10.6.11.102
PING 10.6.11.102 (10.6.11.102) 56(84) bytes of data.

rtt min/avg/max/mdev = 0.653/0.719/0.774/0.043 ms
2. 设定flavor
flavor是一个虚拟机配置的集合体，其中会根据不同的虚拟机规模设定各个资源不同的配比，在创建虚拟机的时候直接调用flavor来设定各资源的使用情况。
(1) 在执行相关flavor的命令之前，要先读取admin-openrc的环境变量脚本文件。
~]# . admin-openrc
(2) 创建flavor
~]# openstack flavor create --id 0 --vcpus 1 --ram 64 --disk 1 m1.nano
+----------------------------+---------+
| Field | Value |
+----------------------------+---------+
| OS-FLV-DISABLED:disabled | False |
| OS-FLV-EXT-DATA:ephemeral | 0 |
| disk | 1 |
| id | 0 |
| name | m1.nano |
| os-flavor-access:is_public | True |
| properties | |
| ram | 64 |
| rxtx_factor | 1.0 |
| swap | |
| vcpus | 1 |
+----------------------------+---------+
(3) 列出已有的flavor
~]# openstack flavor list
+----+---------+-----+------+-----------+-------+-----------+
| ID | Name | RAM | Disk | Ephemeral | VCPUs | Is Public |
+----+---------+-----+------+-----------+-------+-----------+
| 0 | m1.nano | 64 | 1 | 0 | 1 | True |
+----+---------+-----+------+-----------+-------+-----------+
3. 创建密钥对
创建密钥对后，每启动一个虚拟机实例，都会在虚拟机的管理员目录下注入一个密钥对的公钥，这样使得controller节点联系任何虚拟机的时候，都不需要使用密码。
(1) 在执行相关flavor的命令之前，要先读取demo-openrc的环境变量脚本文件。
~]# . demo-openrc
(2) 创建密钥对，并添加一个公钥
~]# ssh-keygen -q -N ""
~]# openstack keypair create --public-key ~/.ssh/id_rsa.pub mykey
+-------------+-------------------------------------------------+
| Field | Value |
+-------------+-------------------------------------------------+
| fingerprint | 6c:f0:d8:7b:eb:6b:c3:66:77:49:51:7b:f3:0a:1c:22 |
| name | mykey |
| user_id | 987e3ca1748d473d8d658f5f34d1ad39 |
+-------------+-------------------------------------------------+
(3) 查看密钥对
~]# openstack keypair list
+-------+-------------------------------------------------+
| Name | Fingerprint |
+-------+-------------------------------------------------+
| mykey | 6c:f0:d8:7b:eb:6b:c3:66:77:49:51:7b:f3:0a:1c:22 |
+-------+-------------------------------------------------+
4. 管理安全组规则
类似于操作系统的防火墙，默认对所有实例使用default安全组规则。对于cirros系统来讲，我们至少要开启ICMP (ping)和secure shell (SSH)。
(1) 在default安全组中设定允许ping
~]# openstack security group rule create --proto icmp default
+-------------------+--------------------------------------+
| Field | Value |

+-------+---------------------------------------------------------------------------------+
- 访问虚拟机实例provider-instance
该步骤遇到错误，具体情况如下：
问题1
provider-instance显示获取了IP地址为10.6.11.108，但是在controller节点无法ping通；
通过dashboard想访问该实例的控制台，提示“ fails to connect ot server (code: 1006) ”
处理：
后来经排障查找，发现是由于compute1节点的selinux和firewalld服务未关闭导致，关闭后恢复正常。
问题2
控制台可以正常连接之后，启动虚拟机实例发现在控制台里系统并没有启动，一直卡在 cirros booting from harddisk... GRUB的黑屏界面无法继续。
处理:
~]# vim /etc/nova/nova.conf
[libvirt]
hw_machine_type = x86_64=pc-i440fx-rhel7.2.0
重启compute1节点后，cirros系统可以正常启动，并通过终端登录系统了。
