我們現在還差openstack的最後一個模塊cinder模塊，存儲節點，那大家現在就有疑問了，虛擬機的存在哪裏呢？
在結算節點上，即是：
[root@linux-node2 ~]# ll /var/lib/nova/instances/
總用量 16

接下來，我們要在控制節點裝cinder。
[root@linux-node1 ~]# cd /usr/local/src/cinder-2014.1
[root@linux-node1 cinder-2014.1]# python setup.py install
[root@linux-node1 cinder-2014.1]# mkdir /etc/cinder
[root@linux-node1 cinder-2014.1]# mkdir /var/log/cinder
[root@linux-node1 cinder-2014.1]# mkdir /var/lib/cinder
[root@linux-node1 cinder-2014.1]# mkdir /var/run/cinder
[root@linux-node1 cinder-2014.1]# cd etc/
[root@linux-node1 etc]# ls
cinder
[root@linux-node1 etc]# cd cinder/
[root@linux-node1 cinder]# ls
api-paste.ini cinder.conf.sample logging_sample.conf policy.json rootwrap.conf rootwrap.d
[root@linux-node1 cinder]# pwd
/usr/local/src/cinder-2014.1/etc/cinder
[root@linux-node1 cinder]# cp -r * /etc/cinder/
[root@linux-node1 cinder]# pwd
/usr/local/src/cinder-2014.1/etc/cinder
[root@linux-node1 cinder]# cd /etc/cinder/
[root@linux-node1 cinder]# ls
api-paste.ini cinder.conf.sample logging_sample.conf policy.json rootwrap.conf rootwrap.d
[root@linux-node1 cinder]# mv cinder.conf.sample cinder.conf
[root@linux-node1 cinder]# mv logging_sample.conf logging.conf
修改cinder配置文件
[root@linux-node1 cinder]# cd ~
[root@linux-node1 ~]# vim /etc/cinder/cinder.conf
connection = mysql://cinder:[email protected]/cinder
同步一下數據庫
[root@linux-node1 ~]# cinder-manage db sync
查看一下成功與否
[root@linux-node1 ~]# mysql -ucinder -pcinder -e"use cinder;show tables;"
ERROR 1045 (28000): Access denied for user 'cinder'@'localhost' (using password: YES)
[root@linux-node1 ~]# mysql -h 192.168.33.11 -ucinder -pcinder -e"use cinder;show tables;"
