openstack--JUNO10搭建手册整理5: horizon && block

八、Dashboard(Horizon)  仪表盘套件
8.1先决条件

• 安装OpenStack compute(nova)和identity(keystone) service。
• 安装Python2.6或2.7，并必须支持Django。
• 你的浏览器必须支持HTML5并启用cookies和JavaScript功能。也别推荐了，就是google浏览器

8.2安装和配置  controller节点
8.2.1安装仪表板组件

yum -y install openstack-dashboard httpd mod_wsgi memcached python-memcached

8.2.2配置仪表板

b && c 两项配置时万分小心！！！

vim /etc/openstack-dashboard/local_settings
a.配置dashboard使用controller节点上的OpenStack服务

OPENSTACK_HOST = "controller.nice.com"  +134

b.设置允许来自所有网络的主机访问dashboard

ALLOWED_HOSTS = ['*', ]         +15#注意这里的写法！ # 不然的话会死的很惨！！

c.配置memcached会话存贮服务 +113  #还有这里的格式！！

CACHES = {
    'default': {
         'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache',
         'LOCATION': 'controller:11211',
    }
}

d.(可选)配置时区

TIME_ZONE = "Asia/Shanghai"  +256

##当浏览器访问报500错误时，仔细检查 b && c 两项配置！
8.2.3完成安装
#8.2.3.1、在RHEL或CentOS上，配置SElinux去允许web服务器访问OpenStack服务(如果你没关SElinux)：
setsebool -P httpd_can_network_connect on

在此，本部直接跳过，因为之前已经在准备工作中已经把selinux关闭！

8.2.3.2.修改相关文件归属，使dashboard CSS可以被加载。

chown -R apache:apache /usr/share/openstack-dashboard/static

8.2.3.3.启动web服务和会话保存服务，并设置开机自动启动。

systemctl enable httpd.service memcached.service
systemctl start httpd.service memcached.service
修改本地C:\Windows\System32\drivers\etc\hosts文件
172.16.253.214 controller.nice.com

google浏览器输入:controller.nice.com/dashboard

如果你已经出现我这个页面，你应该为自己感到骄傲，因为之前所有的努力，在这时终于得到体现。恭喜你，你可以喝点小酒为自己的成就庆祝一下 哈哈

但... ....

 

 

 

 

革命尚未成功，同志仍需努力!

接下来，我们继续，去安装块存储  cinder服务，流程和之前几个服务一样。

九、块存储Block Storage(cinder)
9.1配置先决条件

#controller节点
9.1.1、创建数据库，并完成下列步骤：
a.以数据库管理员root的身份连接数据库：
mysql -u root -ppqjpqj

b.创建cinder数据库

CREATE DATABASE cinder;

c.创建数据库用户cinder，并授予cinder用户对cinder数据库的完全控制权限：

GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'localhost' IDENTIFIED BY 'CINDER_DBPASS';
GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'%' IDENTIFIED BY 'CINDER_DBPASS';

d.exit退出数据库连接

9.2执行admin环境变量脚本
source admin-open9.3在认证服务中创建块存储服务认证信息，完成下列步骤：
a.创建cinder用户

keystone user-create --name cinder --pass CINDER_PASS

+----------+----------------------------------+
| Property |              Value               |
+----------+----------------------------------+
|  email   |                                  |
| enabled  |               True               |
|    id    | 6b303fb56f55477fab0a9ea830ce4be5 |
|   name   |              cinder              |
| username |              cinder              |
+----------+----------------------------------+

b.链接cinder用户到service租户和admin角色
keystone user-role-add --user cinder --tenant service --role admin

c.创建cinder服务

##由于block节点有两块硬盘，所以要创建两个服务和端点！！
 

keystone service-create --name cinder --type volume --description "OpenStack Block Storage"

+-------------+----------------------------------+
|   Property  |              Value               |
+-------------+----------------------------------+

|   enabled   |               True               |
|      id     | a7ede11678da49849e30c579ffdeeccc |
|     name    |              cinder              |
|     type    |              volume              |
+-------------+----------------------------------+
keystone service-create --name cinderv2 --type volumev2 --description "OpenStack Block Storage"

+-------------+----------------------------------+
|   Property  |              Value               |
+-------------+----------------------------------+
| description |     OpenStack Block Storage      |
|   enabled   |               True               |
|      id     | a8fa75dc8b60402b88a89a8c866dda50 |
|     name    |             cinderv2             |
|     type    |             volumev2             |
+-------------+----------------------------------+

d.创建块存储服务端点
keystone endpoint-create \
--service-id $(keystone service-list | awk '/ volume / {print $2}') \
--publicurl http://controller.nice.com:8776/v1/%\(tenant_id\)s \
--internalurl http://controller.nice.com:8776/v1/%\(tenant_id\)s \

exit 退出数据库

9.6完成安装
启动块存储服务并设置开机自动启动：

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

9.7安装并配置block节点
9.7.1配置先决条件

9.7.1.1启动LVM服务并设置开机自启动(根据自身情况)

systemctl enable lvm2-lvmetad.service
systemctl start lvm2-lvmetad.service
systemctl restart lvm2-lvmetad.service

9.7.1.2、创建物理卷/dev/sdb:

pvcreate /dev/sdb

9.7.1.3创建卷组cinder-volumes(名字不要改):

vgcreate cinder-volumes /dev/sdb

9.7.1.4vi /etc/lvm/lvm.conf

#使系统只扫描启用LVM的磁盘。防止识别其他非LVM磁盘对块存储服务造成影响。
编辑devices小节，添加过滤器允许/dev/sdb磁盘，拒绝其他设备。

devices {
...
filter = [ "a/sdb/", "r/.*/" ]  +87 #正确写法，注意两边空格  系统没加逻辑卷组！

}

#警告：如果你的系统磁盘使用了LVM，则必须添加系统盘到过滤器中：
filter = [ "a/sda", "a/sdb/", "r/.*/"]
同样，如果conpute节点的系统盘也使用了LVM，则也需要修改
/etc/lvm/lvm.conf文件。并添加过滤器。

9.7.2安装并配置块存储卷组件
9.7.2.1安装软件包

yum -y install openstack-cinder targetcli python-oslo-db MySQL-python

9.7.2.2
vi /etc/cinder/cinder.conf

[database]
connection=mysql://cinder:[email protected]/cinder  +2359

[DEFAULT]

glance_host=controller.nice.com  +500
iscsi_helper=lioadm  +1064
verbose=True  +774

9.7.3完成安装
启动块存储volume服务和iSCSI服务，并设置开机自动启动。

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

9.7.4验证(在controller节点完成下列操作)
9.7.4.1、执行admin环境变量脚本
source admin-open

9.7.4.2、列出服务组件确认每个进程启动成功

cinder service-list
+------------------+---------------------+------+---------+-------+----------------------------+-----------------+
|      Binary      |         Host        | Zone |  Status | State |         Updated_at         | Disabled Reason |
+------------------+---------------------+------+---------+-------+----------------------------+-----------------+
| cinder-scheduler | controller.nice.com | nova | enabled |   up  | 2018-10-04T19:03:44.000000 |       None      |
|  cinder-volume   |    block.nice.com   | nova | enabled |   up  | 2018-10-04T19:03:41.000000 |       None      |
+------------------+---------------------+------+---------+-------+----------------------------+-----------------+

两个，一个都不能少，如果少的话，检查命令与配置文件！！或恢复快照重新做！！

9.7.4.3、执行demo用户环境变量脚本
source demo-open

9.7.4.4、创建1GB的卷

cinder create --display-name demo-volume1 1
+---------------------+--------------------------------------+
|       Property      |                Value                 |
+---------------------+--------------------------------------+
|     attachments     |                  []                  |
|  availability_zone  |                 nova                 |
|       bootable      |                false                 |
|      created_at     |      2018-10-08T09:37:31.498178      |
| display_description |                 None                 |
|     display_name    |             demo-volume1             |
|      encrypted      |                False                 |
|          id         | 1454945c-2225-4369-bd19-6ba99ae17974 |
|       metadata      |                  {}                  |
|         size        |                  1                   |
|     snapshot_id     |                 None                 |
|     source_volid    |                 None                 |
|        status       |               creating               |
|     volume_type     |                 None                 |
+---------------------+--------------------------------------+

9.7.4.5、确认卷已创建并可用

cinder list
+--------------------------------------+-----------+--------------+------+-------------+----------+-------------+
|                  ID                  |   Status  | Display Name | Size | Volume Type | Bootable | Attached to |
+--------------------------------------+-----------+--------------+------+-------------+----------+-------------+
| 1454945c-2225-4369-bd19-6ba99ae17974 | available | demo-volume1 |  1   |     None    |  false   |             |
+--------------------------------------+-----------+--------------+------+-------------+----------+-------------+
#可用性状态必须是available，不能是error！

至此，block节点--cinder服务也亦完毕！

我们小时候上学写作文，有“开头--中间--结尾”三部分，cinder顺利搭建完，就宣告我们的openstack作文中间段写完了，最后就是收拾了。

马上就到终点了，坚持住，不要行百里都半九十。九十九度的水和十度的水没区别，都不是开水，就差你最后一把火了！
