openstack-dashboard部署

因为在CT控制节点已安装httpd服务，而Dashboard控制台也需要httpd支持，所以此处可以在C1节点进行安装httpd

yum -y install openstack-dashboard httpd

修改local_setting本地控制台的配置文件

cd /etc/openstack-dashboard/
vim local_settings 
#修改的内容如下：
#修改local_setting本地控制台的配置文件
import os								#使用Python导入一个模块
from django.utils.translation import ugettext_lazy as _
from openstack_dashboard.settings import HORIZON_CONFIG
DEBUG = False							#不开启调式	
ALLOWED_HOSTS = ['*']						#只允许通过列表中指定的域名访问dashboard；允许通过指定的IP地址及域名访问dahsboard；
								['*']表示允许所有域名
LOCAL_PATH = '/tmp'
SECRET_KEY='f8ac039815265a99b64f'
SESSION_ENGINE = 'django.contrib.sessions.backends.cache'		#指定session引擎
CACHES = {							#95-100行取消"#"注释
    'default': {
         'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache',
         'LOCATION': 'ct:11211',	#指定memcache地址及端口
    }
}
#以下配置session信息存放到memcache中；session信息不仅可以存放到memcache中，也可以存放到其他地方
EMAIL_BACKEND = 'django.core.mail.backends.console.EmailBackend'		#108行修改
OPENSTACK_HOST = "ct"						#118-127行修改
OPENSTACK_KEYSTONE_URL = "http://%s:5000/v3" % OPENSTACK_HOST	
OPENSTACK_KEYSTONE_MULTIDOMAIN_SUPPORT = True			#让dashboard支持域
OPENSTACK_API_VERSIONS = {
    "identity": 3,
    "image": 2,
    "volume": 3,
}
#配置openstack的API版本
OPENSTACK_KEYSTONE_DEFAULT_DOMAIN = "Default"
OPENSTACK_KEYSTONE_DEFAULT_ROLE = "user"


OPENSTACK_NEUTRON_NETWORK = {					#132行到152行修改
    'enable_auto_allocated_network': False,
    'enable_distributed_router': False,
    'enable_fip_topology_check': False,
    'enable_ha_router': False,
    'enable_lb': False,

}
#定义使用的网络类型，[*]表示

TIME_ZONE = "Asia/Shanghai"					#156行修改

重启服务

重新生成openstack-dashboard.conf并重启Apache服务
（由于dashborad会重新复制代码文件，重启apache会比较慢）

cd /usr/share/openstack-dashboard
python manage.py make_web_conf --apache > /etc/httpd/conf.d/openstack-dashboard.conf
systemctl enable httpd.service
systemctl restart httpd.service

重启 ct 节点的 memcache 服务

systemctl restart memcached.service

验证操作
打开浏览器，在地址栏中输入“http://192.168.241.10”，进入Dashboard登录页面。
在登录页面依次填写：“域：default、用户名：admin、密码:ADMIN_PASS”（在~.bashrc中已定义）
完成后，进行登陆

OpenStack-cinder部署

创建数据库实例和角色

ct节点创建

 mysql -uroot -p123123
CREATE DATABASE cinder;
GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'localhost' IDENTIFIED BY 'CINDER_DBPASS';
GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'%' IDENTIFIED BY 'CINDER_DBPASS';
flush privileges;
quit

在这里插入图片描述

#创建用户、修改配置文件

openstack user create --domain default --password CINDER_PASS cinder						#创建cinder用户,密码设置为CINDER_PASS
openstack role add --project service --user cinder admin													#把cinder用户添加到service服务中，并授予admin权限

##cinder有v2和v3两个并存版本的API，所以需要创建两个版本的service实例
openstack service create --name cinderv2 --description "OpenStack Block Storage" volumev2		
openstack service create --name cinderv3 --description "OpenStack Block Storage" volumev3

在这里插入图片描述

给v2和v3版本的api创建endpoint

openstack endpoint create --region RegionOne volumev2 public http://ct:8776/v2/%\(project_id\)s
 openstack endpoint create --region RegionOne volumev2 internal http://ct:8776/v2/%\(project_id\)s
 openstack endpoint create --region RegionOne volumev2 admin http://ct:8776/v2/%\(project_id\)s
 openstack endpoint create --region RegionOne volumev3 public http://ct:8776/v3/%\(project_id\)s
 openstack endpoint create --region RegionOne volumev3 internal http://ct:8776/v3/%\(project_id\)s
 openstack endpoint create --region RegionOne volumev3 admin http://ct:8776/v3/%\(project_id\)s

yum 安装cinder 服务和修改cinder配置文件

yum -y install openstack-cinder

cp /etc/cinder/cinder.conf{,.bak}
grep -Ev '#|^$' /etc/cinder/cinder.conf.bak>/etc/cinder/cinder.conf
openstack-config --set /etc/cinder/cinder.conf database connection mysql+pymysql://cinder:CINDER_DBPASS@ct/cinder
openstack-config --set /etc/cinder/cinder.conf DEFAULT transport_url rabbit://openstack:RABBIT_PASS@ct
openstack-config --set /etc/cinder/cinder.conf DEFAULT auth_strategy keystone
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken www_authenticate_uri http://ct:5000
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken auth_url http://ct:5000
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken memcached_servers ct:11211
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken auth_type password
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken project_domain_name default
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken user_domain_name default
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken project_name service
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken username cinder
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken password CINDER_PASS
openstack-config --set /etc/cinder/cinder.conf DEFAULT my_ip 192.168.241.9		
openstack-config --set /etc/cinder/cinder.conf oslo_concurrency lock_path /var/lib/cinder/tmp

同步cinder数据库(填充块存储数据库)

su -s /bin/sh -c "cinder-manage db sync" cinder

修改 Nova 配置文件，并重启服务。

openstack-config --set /etc/nova/nova.conf cinder os_region_name RegionOne

systemctl restart openstack-nova-api.service

配置Cinder服务和控制节点验证

systemctl enable openstack-cinder-api.service openstack-cinder-scheduler.service
systemctl start openstack-cinder-api.service openstack-cinder-scheduler.service

cinder service-list

在计算节点c2配置Cinder（存储节点）

yum -y install openstack-cinder targetcli python-keystone
yum -y install lvm2 device-mapper-persistent-data
systemctl enable lvm2-lvmetad.service
systemctl start lvm2-lvmetad.service

创建lvm物理卷和卷组

Pvcreate /dev/sdc 
Vgcreate cinder-volumes /dev/sdc

修改lvm配置文件(指定使用sdc磁盘）

● 141行，取消注释，修改filter规则，如下：
filter = [ "a/sdc/","r/.*/" ]
# a表示允许，r表示拒绝 
# 只允许lvm服务访问sdc中的数据，不允许lvm服务访问其他磁盘，这也间接实现了openstack创建的虚拟机只能访问sdb中的数据，不能访问其他磁盘 
# 设置只允许实例访问sdc逻辑卷中的数据；如果不配置的话，本机的其他服务也有可能会访问sdc逻辑卷中的数据

重启lvm服务

systemctl restart lvm2-lvmetad.service

配置cinder模块

cp /etc/cinder/cinder.conf{,.bak}
grep -Ev '#|^$' /etc/cinder/cinder.conf.bak>/etc/cinder/cinder.conf

openstack-config --set /etc/cinder/cinder.conf  database  connection mysql+pymysql://cinder:CINDER_DBPASS@ct/cinder
openstack-config --set /etc/cinder/cinder.conf  DEFAULT transport_url rabbit://openstack:RABBIT_PASS@ct
openstack-config --set /etc/cinder/cinder.conf  DEFAULT auth_strategy keystone
openstack-config --set /etc/cinder/cinder.conf  DEFAULT my_ip 192.168.100.13
openstack-config --set /etc/cinder/cinder.conf  DEFAULT enabled_backends lvm
openstack-config --set /etc/cinder/cinder.conf  DEFAULT glance_api_servers http://ct:9292
openstack-config --set /etc/cinder/cinder.conf  keystone_authtoken www_authenticate_uri http://ct:5000
openstack-config --set /etc/cinder/cinder.conf  keystone_authtoken auth_url http://ct:5000
openstack-config --set /etc/cinder/cinder.conf  keystone_authtoken memcached_servers ct:11211
openstack-config --set /etc/cinder/cinder.conf  keystone_authtoken auth_type password
openstack-config --set /etc/cinder/cinder.conf  keystone_authtoken project_domain_name default
openstack-config --set /etc/cinder/cinder.conf  keystone_authtoken user_domain_name default
openstack-config --set /etc/cinder/cinder.conf  keystone_authtoken project_name service
openstack-config --set /etc/cinder/cinder.conf  keystone_authtoken username cinder
openstack-config --set /etc/cinder/cinder.conf  keystone_authtoken password CINDER_PASS
openstack-config --set /etc/cinder/cinder.conf  lvm volume_driver cinder.volume.drivers.lvm.LVMVolumeDriver
openstack-config --set /etc/cinder/cinder.conf  lvm volume_group cinder-volumes
openstack-config --set /etc/cinder/cinder.conf  lvm target_protocol iscsi
openstack-config --set /etc/cinder/cinder.conf  lvm target_helper lioadm
openstack-config --set /etc/cinder/cinder.conf  oslo_concurrency lock_path /var/lib/cinder/tmp

开启cinder卷服务

systemctl enable openstack-cinder-volume.service target.service
systemctl start openstack-cinder-volume.service target.service

查看卷列表

openstack volume service list
