在 ubuntu 14.04 上安装ceph calamari时，遇到calamari web界面中node server可以正常添加，但cluster 集群无法显示的问题。
经过定位，是因为saltstack master/minion 版本不匹配问题。 特记录正确的安装过程。
Note: Calamari does not currently support 2015.5 salt please consider using 2014.7 instead Also it is important for salt-master and minion versions to match.
参考英文文档
http://calamari.readthedocs.org/en/latest/operations/server_install.html#installing-calamari-server
http://calamari.readthedocs.org/en/latest/operations/minion_connect.html
在ceph admin node执行如下步骤
1. 添加salt apt 源 并安装 salt master/minion
https://docs.saltstack.com/en/latest/topics/installation/ubuntu.html
wget -O - https://repo.saltstack.com/apt/ubuntu/14.04/amd64/latest/SALTSTACK-GPG-KEY.pub | sudo apt-key add -
sudo echo "deb http://repo.saltstack.com/apt/ubuntu/14.04/amd64/latest trusty main" >> /etc/apt/sources.list
sudo apt-get update && apt-get install salt-master salt-minion
2. 安装依赖包
sudo apt-get update && sudo apt-get install -y apache2 libapache2-mod-wsgi libcairo2 supervisor python-cairo libpq5 postgresql
3. 下载calamari-clients 和 calamari-server Deb安装包 并安装
wget http://download.ceph.com/calamari/1.3.1/ubuntu/trusty/pool/main/c/calamari-clients/calamari-clients_1.3.1.1-1trusty_all.deb
wget http://download.ceph.com/calamari/1.3.1/ubuntu/trusty/pool/main/c/calamari/calamari-server_1.3.1.1-1trusty_amd64.deb
sudo dpkg -i calamari-server*.deb calamari-clients*.deb
sudo calamari-ctl initialize
4. ceph-deploy 安装 calamari
Create a ceph-deploy configuration file at ~/.cephdeploy.conf
[ceph-deploy-calamari]
master = {master}
{master} should be the FQDN of the Calamari server, for example acme.mydomain.com or 10.10.9.8
ceph-deploy calamari connect <node1> [<node2> ...]
