server ntp1.aliyun.com iburst

• 安装openstack软件包（所有节点）

yum install centos-release-openstack-queens -y
yum install python-openstackclient -y

• 如果selinux没有禁用（所有节点）

CentOS7 minimal 关闭 firewall NetworkManager selinux
安装 openstack-selinux软件包以自动管理OpenStack服务的安全策略
yum install openstack-selinux -y

• 配置sql（仅控制节点）

1. 下载
   yum install mariadb mariadb-server python2-PyMySQL -y
2. 备份配置
   cd /etc/my.cnf.d/
tar czvf my.cnf.d.tar.gz *
3. 创建配置openstack.cnf
vi openstack.cnf

[mysqld]
bind-address = 192.168.0.51

default-storage-engine = innodb
innodb_file_per_table = on
max_connections = 4096
collation-server = utf8_general_ci
character-set-server = utf8

4. 启动
   systemctl enable mariadb.service && systemctl start mariadb.service
5. 配置数据库安装密码（可选）
   mysql_secure_installation
6. 修改密码
   登录：mysql -u root mysql
   改密码：UPDATE user SET PASSWORD=PASSWORD('123456') where USER='root';
FLUSH PRIVILEGES;
   退出：quit
   重启服务：systemctl restart mariadb.service
   注：发现如果不重启服务，那么密码不生效

• 消息队列RabbitMQ（控制节点）

1. 下载
   yum install rabbitmq-server -y
2. 启动
   systemctl enable rabbitmq-server.service && systemctl start rabbitmq-server.service
3. 添加openstack用户

• keystone（控制节点）

1. 创建数据库
   mysql -uroot -p123456
CREATE DATABASE keystone;
GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'localhost' IDENTIFIED BY '123456';
GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'controller' IDENTIFIED BY '123456';
GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%' IDENTIFIED BY '123456';
2. 安装配置
   yum install openstack-keystone httpd mod_wsgi -y
vi /etc/keystone/keystone.conf

[database]
connection = mysql+pymysql://keystone:123456@controller/keystone

[token]
provider = fernet

3. 填充数据库
   su -s /bin/sh -c "keystone-manage db_sync" keystone
4. 初始化Fernet密钥存储库
   keystone-manage fernet_setup --keystone-user keystone --keystone-group keystone
keystone-manage credential_setup --keystone-user keystone --keystone-group keystone
5. 引导身份服务
   keystone-manage bootstrap --bootstrap-password 123456 --bootstrap-admin-url http://controller:5000/v3/ --bootstrap-internal-url http://controller:5000/v3/ --bootstrap-public-url http://controller:5000/v3/ --bootstrap-region-id RegionOne
   注：keystone-manage bootstrap命令实际上是创建了default domain
6. 配置Apache HTTP服务器
   vi /etc/httpd/conf/httpd.conf

ServerName controller

ln -s /usr/share/keystone/wsgi-keystone.conf /etc/httpd/conf.d/

7. 启动httpd
   systemctl enable httpd.service && systemctl start httpd.service
8. 登录admin

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:5000/v3
export OS_IDENTITY_API_VERSION=3

9. 创建exampledomain（这个可用可不用，只是一个创建domain的示例）
   openstack domain create --description "An Example Domain" example
10. 创建service project
    openstack project create --domain default --description "Service Project" service
    注：service project是给服务用的，每个服务会使用唯一的user添加到serviceproject中
11. 创建非特权用户和项目（这就是创建用户、角色、项目的一般步骤，可用可不用，也是一个示例）
    openstack project create --domain default --description "Demo Project" demo
openstack user create --domain default --password-prompt demo
openstack role create user
openstack role add --project demo --user demo user
    注：user角色是必须存在的，否则在管理端创建项目的时候会失败
12. demo用户登录

export OS_PROJECT_DOMAIN_NAME=Default
export OS_USER_DOMAIN_NAME=Default
export OS_PROJECT_NAME=demo
export OS_USERNAME=demo
export OS_PASSWORD=123456
export OS_AUTH_URL=http://controller:5000/v3
export OS_IDENTITY_API_VERSION=3
export OS_IMAGE_API_VERSION=2

12. 请求admin用户身份认证令牌
    openstack --os-auth-url http://controller:5000/v3 --os-project-domain-name Default --os-user-domain-name Default --os-project-name admin --os-username admin token issue
    注：参数跟8.登录admin是一样的，如果存在相应环境变量，那么对应参数可以忽略，比如执行了8.登录admin，那么获取token只需要使用
    openstack token issue
13. 请求demo用户身份认证令牌
    openstack --os-auth-url http://controller:5000/v3 --os-project-domain-name Default --os-user-domain-name Default --os-project-name demo --os-username demo token issue

GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'%' IDENTIFIED BY '123456';
2. 创建glance用户（其domain、project、角色）
   . admin-openrc
openstack user create --domain default --password-prompt glance
openstack role add --project service --user glance admin
   注：前面说过serviceproject用于服务，现在就把glance用户添加到serviceproject中，并且添加管理员角色
3. 创建glance服务
   openstack service create --name glance --description "OpenStack Image" image
openstack endpoint create --region RegionOne image public http://controller:9292
openstack endpoint create --region RegionOne image internal http://controller:9292
openstack endpoint create --region RegionOne image admin http://controller:9292
   注：openstack service create中glance是服务名，image是服务type，这个应该是随意的
4. 安装glance包
   yum install openstack-glance -y
5. 配置

5. 配置lvm仅扫描/dev/vda
vi /etc/lvm/lvm.conf

devices {

filter = [ "a/vda/", "r/.*/"]

配置/etc/lvm/lvm.conf的原因
注：上面a是accept，r是reject

* cinder（在块存储节点）

1. 安装
   yum install openstack-cinder targetcli python-keystone -y
2. 配置
   vi /etc/cinder/cinder.conf

[DEFAULT]
transport_url = rabbit://openstack:123456@controller
auth_strategy = keystone
my_ip = 192.168.0.53
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:5000
memcached_servers = controller:11211
auth_type = password
project_domain_id = default
user_domain_id = default
project_name = service
username = cinder
password = 123456

[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

enabled_backends = lvm的lvm和[lvm]是关联的，enabled_backends是任意的，比如enabled_backends = lvm1，就有[lvm1]

3. 启动
   systemctl enable openstack-cinder-volume.service target.service && systemctl start openstack-cinder-volume.service target.service
4. 验证（在控制节点）
   openstack volume service list

• dashboard（控制节点）

1. 下载
   yum install openstack-dashboard -y
2. 配置
   vi /etc/openstack-dashboard/local_settings

OPENSTACK_HOST = "controller"
OPENSTACK_KEYSTONE_URL = "http://%s:5000/v3" % OPENSTACK_HOST
OPENSTACK_KEYSTONE_DEFAULT_ROLE = "user"

ALLOWED_HOSTS = ['*']

SESSION_ENGINE = 'django.contrib.sessions.backends.cache'
CACHES = {
   'default': {
        'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache',
        'LOCATION': 'controller:11211',
   }
}
OPENSTACK_KEYSTONE_MULTIDOMAIN_SUPPORT = True
OPENSTACK_API_VERSIONS = {
   "identity": 3,
   "image": 2,
   "volume": 2,
}
OPENSTACK_KEYSTONE_DEFAULT_DOMAIN = "Default"
OPENSTACK_NEUTRON_NETWORK = {
   ...
   'enable_router': False,
   'enable_quotas': False,
   'enable_distributed_router': False,
   'enable_ha_router': False,
   'enable_lb': False,
   'enable_firewall': False,
   'enable_vpn': False,
   'enable_fip_topology_check': False,
}
TIME_ZONE = "UTC"

注：'enable_router': True,可以使用路由器（router），但是这个必须有self-service network

3. 配置
   vi /etc/httpd/conf.d/openstack-dashboard.conf

WSGIApplicationGroup %{GLOBAL}

4. 启动服务
   systemctl restart httpd.service memcached.service
5. 访问
   http://controller/dashboard
