Openstack Cinder安装向导：在Unitestack的UOS下测试

问题导读：
1.Cinder安装需要哪些步骤？
2.endpoint有哪些参数，你认为它的作用是什么？
3.如何检测cinder服务是否正常？
扩展
4.你认为配置文件的作用是什么？





在Unitestack的UOS下测试，看来今天要把cinder装上才行。老外的文档还没出来，我就只能对着官方文档，慢慢整理。

采用单独的存储节点作为存储.


控制节点
在控制节点上,我们需要安装cinder api和schedule两个服务.

apt-get -y install cinder-api cinder-scheduler
复制代码

创建数据库

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';
exit;
复制代码

创建用户

keystone user-create --name=cinder --pass=service_pass --email=cinder@domain.com
keystone user-role-add --user=cinder --tenant=service --role=admin
复制代码

endpoint

keystone service-create --name=cinder --type=volume --description="OpenStack Block Storage"
keystone endpoint-create \
  --service-id=$(keystone service-list | awk '/ volume / {print $2}') \
  --publicurl=http://10.0.0.11:8776/v1/%\(tenant_id\)s \
  --internalurl=http://10.0.0.11:8776/v1/%\(tenant_id\)s \
  --adminurl=http://10.0.0.11:8776/v1/%\(tenant_id\)s

keystone service-create --name=cinderv2 --type=volumev2 --description="OpenStack Block Storage v2"
keystone endpoint-create \
  --service-id=$(keystone service-list | awk '/ volumev2 / {print $2}') \
  --publicurl=http://10.0.0.11:8776/v2/%\(tenant_id\)s \
  --internalurl=http://10.0.0.11:8776/v2/%\(tenant_id\)s \
  --adminurl=http://10.0.0.11:8776/v2/%\(tenant_id\)s
复制代码

修改配置文件 /etc/cinder.conf

[DEFAULT]
rootwrap_config = /etc/cinder/rootwrap.conf
api_paste_confg = /etc/cinder/api-paste.ini
iscsi_helper = tgtadm
volume_name_template = volume-%s
volume_group = cinder-volumes
verbose = True
auth_strategy = keystone
state_path = /var/lib/cinder
lock_path = /var/lock/cinder
volumes_dir = /var/lib/cinder/volumes

rpc_backend = cinder.openstack.common.rpc.impl_kombu
rabbit_host = 10.0.0.11
rabbit_port = 5672
rabbit_userid = guest
rabbit_password = guest



[database]
connection = mysql://cinder:CINDER_DBPASS@10.0.0.11/cinder


[keystone_authtoken]
auth_uri = http://10.0.0.11:5000
auth_host = 10.0.0.11
auth_port = 35357
auth_protocol = http
admin_tenant_name = service
admin_user = cinder
admin_password = service_pass
复制代码

同步数据库

cinder-manage db sync
复制代码

重启服务

service cinder-scheduler restart
service cinder-api restart
复制代码

存储节点
创建一个虚拟机，只需要1块网卡就可以，接入到管理网络里就可以。

存储节点的IP为：10.0.0.41，不过我们需要上网安装软件，所以把虚拟机接入到外部网络，装完后，可以断掉。创建1块100G的云硬盘，作为cinder volume使用。

升级内核

apt-get update -y && apt-get upgrade -y && apt-get dist-upgrade
复制代码

安装lvm工具

apt-get install lvm2
复制代码

安装iscsi软件

apt-get -y install iscsitarget open-iscsi iscsitarget-dkms
复制代码

最新版本的内核有冲突，内核版本要降级。

apt-get install linux-headers-3.13.0-32-generic
复制代码

配置iscsi服务

sed -i 's/false/true/g' /etc/default/iscsitarget
复制代码

重启服务

service iscsitarget start
service open-iscsi start
复制代码

同步时间

apt-get install -y ntp
复制代码

编辑 /etc/ntp.conf

server 10.0.0.11
复制代码

重启NTP服务

service ntp restart
复制代码

安装python-mysqldb，因为需要通过python去连接数据库

apt-get install python-mysqldb
复制代码

创建cinder-volumes卷

pvcreate /dev/vdb
vgcreate cinder-volumes /dev/vdb
复制代码

编辑 /etc/lvm/lvm.conf 添加一个filter

 # By default we accept every block device:
    filter = [ "a/.*/" ]
    filter = [ "a/vda1/", "a/vdb/", "r/.*/"]
复制代码

安装cinder

apt-get -y install cinder-volume
复制代码

编辑 /etc/cinder/cinder.conf , 和控制节点区别就在多了一个glance host的设置

[DEFAULT]
rootwrap_config = /etc/cinder/rootwrap.conf
api_paste_confg = /etc/cinder/api-paste.ini
iscsi_helper = tgtadm
volume_name_template = volume-%s
volume_group = cinder-volume
verbose = True
auth_strategy = keystone
state_path = /var/lib/cinder
lock_path = /var/lock/cinder
volumes_dir = /var/lib/cinder/volumes

glance_host = 10.0.0.11

rpc_backend = cinder.openstack.common.rpc.impl_kombu
rabbit_host = 10.0.0.11
rabbit_port = 5672
rabbit_userid = guest
rabbit_password = guest



[database]
connection = mysql://cinder:CINDER_DBPASS@10.0.0.11/cinder


[keystone_authtoken]
auth_uri = http://10.0.0.11:5000
auth_host = 10.0.0.11
auth_port = 35357
auth_protocol = http
admin_tenant_name = service
admin_user = cinder
admin_password = service_pass
复制代码

重启服务

service cinder-volume restart
service tgt restart
复制代码

验证

检测cinder服务是否正常

# cinder service-list
+------------------+------------+------+---------+-------+----------------------------+
|      Binary      |    Host    | Zone |  Status | State |         Updated_at         |
+------------------+------------+------+---------+-------+----------------------------+
| cinder-scheduler | controller | nova | enabled |   up  | 2014-09-04T17:13:28.000000 |
|  cinder-volume   |   cinder   | nova | enabled |   up  | 2014-09-04T17:13:27.000000 |
+------------------+------------+------+---------+-------+----------------------------+
复制代码

创建一个卷

cinder list
cinder create --display-name myVolume 1
复制代码
