在Ceph Calamari的安装（Ubuntu 14.04）过程中遇到很多问题，现总结如下：
1 saltstack报错：The Salt Master has rejected this minion's public key!
在启动salt minion的时候saltstack报错：The Salt Master has rejected this minion's public key!这个问题是由于salt minion的id有问题导致的，解决此问题的方法是首先到master上删除saltstack的minion缓存，文件目录位置在： /etc/salt/pki/master/minions。然后到salt minion的服务器上，修改minion的配置文件将id设置为正确的值。
2 IOError: [Errno 13] Permission denied: '/var/log/calamari/cthulhu.log'
访问权限问题，需要更改该文件的权限为www-data3 cthulhu和carbon-cache进程状态错误
通过supervisorctl返现上述进程状态错误，网页登录存在问题。重启supervisor守护进程解决。4 部分API调用报500错误
日志如下

mons = mon_status['monmap']['mons']
TypeError: 'NoneType' object has no attribute '__getitem__'该问题是因为saltstack版本不兼容，用Version: 0.17.5+ds-1版本的salt可解决该问题。
5 在进行初始化时报错
该问题也是由于Salt版本的问题造成。
