openstack之dashboard与cinder(一)
dashboard必备的是nova neutron glance keystone其他的服务可以先安装，但是不能提前注册，否则dashboard打不开，比如cinder提前注册了，dashboard启动后看到cinder注册的东西了，
就会连接cinder，但是cinder你还没配置好，所以dashboard就无法启动了。
herizon只需要连接到keystone就行了，herizion登录也是用的keystone认证的用户
安装：
yum install openstack-dashboard -y
配置：
vim /etc/openstack-dashboard/local_settings
29 ALLOWED_HOSTS = ['*',] #允许哪些主机连接
103 SECRET_KEY='30110465420bb59687ce' #默认的没有修改
108 CACHES = { #memcache缓存的配置
109 'default': {
110 'BACKEND': 'django.core.cache. backends.memcached. MemcachedCache',
111 'LOCATION': '192.168.56.11:11211',
112 }
113 }
138 OPENSTACK_HOST = "192.168.56.11" #keystone主机所在位置
140 OPENSTACK_KEYSTONE_DEFAULT_ROLE = "user"#使用keystone默认哪个角色
320 TIME_ZONE = "Asia/Shanghai" #时区设置
重启httpd服务
systemctl restart httpd
打开浏览器输入：http://192.168.56.11/dashboard/
使用demo用户demo密码登录
遇到的故障:dashboard无法启动，现象：重启httpd后，把keystone服务挤掉，注释掉/etc/httpd/conf.d/openstack-dashboard.conf 之后
再次启动httpd服务，keystone恢复正常
最后解决：把keystone安装在另外一台机器上就可以了，（注意修改连接memcache和keystone的主机IP）
1块存储：硬盘 LVS DAS（直连式存储）SAN存储（FC-SAN IP-SAN）
2文件存储: NFS nas
3对象存储：分布式存储（ceph PB级）
分布式存储：ceph
cinder：提供云硬盘，云硬盘的瓶颈为网络
组件介绍：
cinder-api：接受API请求并将请求路由到 cinder-volume 来执行。 (作用类似nova-api的)
cinder-volume：响应请求，读取或写向块存储数据库为维护状态，通过信息队列机制与其他进程交互，
或直接与上层块存储提供的硬件或软件进行交互。通过驱动结构，他可以与众多的存储提供者进行交互。
可以有多个。（作用类似nova-compute）
cinder-scheduler：守护进程，为存储卷的实例选取最优的块存储供应节点。(类似于nova-scheduler)
基于三个组件的作用划分，通常我们将
cinder-api和cinder-shceduler 安装在控制节点上，
把cinder-volume安装在存储节点上。（本次实验安装在计算节点的一块单独的硬盘上）
控制节点上：
yum install openstack-cinder python-cinderclient -y
# yum install openstack-cinder python-cinderclient -y
# vim /etc/cinder/cinder.conf
2516 connection = mysql://cinder:cinder@192.168.56.11/cinder
同步数据库：
# su -s /bin/sh -c "cinder-manage db sync" cinder
确认是否同步成功
# mysql -ucinder -pcinder -h 192.168.56.11 -e "use cinder;show tables;"
