1. Calamari简介
Calamari是管理和监控Ceph集群的工具，它提供了一个使得监控惊人地简单方便漂亮的控制面板界面。Calamari 最初是Inktank公司Ceph企业产品包的一部分，在几个月前被Red Hat公司开源了（注：Inktank公司被Red Hat公司收购了）。因此，Calamari是一个成熟的开源企业软件。
如果想要知道如何为Ceph集群部署Calamari，这篇文档将以手把手的介绍引导你。到目前为止，官方还没有为Calamari提供预编译好了的安装包。我们将需要从源代码编译得到安装包，进而再安装并运行Calamari。
Calamari是管理和监控Ceph集群的工具，它展现了一个高级REST API。
Calamari由两个部分组成(分别有两个源代码仓库，目前存在于Ceph Github项目仓库里)。
1.1 Calamari服务端
Calamari服务端程序用Python 2.6编写的，使用了Saltstack, ZeroRPC, gevent, Django, django-rest-framework, graphite工具或包，还为同其它系统进行集成而实现了一个新的REST API，这是一个重要的特性，因为Calamari的早期版本是基于Ceph自己的REST API的。新的Calamari REST API被设计为更加广泛使用并将成为希望与Ceph集群相互影响的新的开发尝试的基础。项目源码：https://github.com/ceph/calamari
1.2. Calamari客户端
Calamari客户端是主要由使用了Calamari REST API的Javascript脚本实现的WEB浏览器界面，项目源码: https://github.com/ceph/calamari-clients
Calamari服务端组件包含：Apache, salt-master , supervisord , cthulhu , carbon-cache Calamari客户端组件包含：salt-minion , diamond
1.3. 从源代码编译Calamari
不象Ceph , Calamari没有提供预编译好的RPM/DEB安装包。如果你对Calamari感兴趣，你需要编译基于你的Linux发行版的相应安装包。为部署Calamari , 你需要分别编译Calamari服务端安装包和Calamari客户端安装包。

2. 编译Calamari服务端安装包
编译Calamari安装包，可以在个人工作用机器上编译，编译机器的OS也不要求一定是CentOS 7.1。
2.1 安装git、Vagrant和Virtualbox
大多数Linux发行版自带git工具，在当初安装OS时就已经自动安装了。如果没有安装，参考其他相关文档安装。
安装Vagrant和Virtualbox可以参考：在CentOS7.1上安装vagrant及virtualbox
2.2. Clone Calamari服务端和Diamond项目源码

cd ~/calamari-repo

2.4. 初始化并启动编译虚拟机
Calamari的编译过程在Vagrant虚拟机里进行，vagrant up命令获取一个虚拟机镜像，并以该镜像作为模板克隆出一个虚拟机实例，然后初始化这个实例并启动它。

执行vagrant up后，系统会自动去vagrant的box收录站https://atlas.hashicorp.com去下载Centos 7.1的虚拟机镜像文件。
因为首次vagrant up要从远程收录站下载镜像导致很费时，我们也可以手动下载：
wget https://atlas.hashicorp.com/boxcutter/boxes/centos71/versions/2.0.1/providers/virtualbox.box
然后修改Vagrantfile文件，在config.vm.box下面添加下面这行：
config.vm.box_url = "file:///root/work/virtualbox.box"
保存文件，以后再vagrant up就从本地镜像克隆出新的虚拟机并启动。
注：通过下载镜像文件并从本地加载镜像的意义在于：如果vagrant虚拟机在操作过程中出现了不明原因的故障问题，一个较快且简单的解决办法是重新初始化vagrant虚拟机。这时就不用再从远程收录站下载镜像。
2.5. 登录vagrant虚拟机
登录到在上一步中启动的centos 7.1 vagrant虚拟机。
# vagrant ssh
[vagrant@localhost ~]$
[vagrant@localhost ~]$ df -h

2.6. 编译Calamari服务端安装包
[vagrant@localhost ~]$ sudo salt-call state.highstate

最后出现上面的输出表明编译成功。这时会在虚拟机的/git目录（即主机的/root/calamari-repo目录）下生成编译好的RPM安装包。
[vagrant@localhost ~]$ ls /git -l
total 32508
drwxrwxr-x. 1 vagrant vagrant 4096 Jul 31 09:12 calamari

-rw-r--r--. 1 vagrant vagrant 290313 Aug 3 02:36 diamond-3.4.67-0.src.rpm
退出vagrant 虚拟机。
3. 编译Calamari客户端安装包
由于至目前Calamari编译过程还不是很成熟，需要用ubuntu vagrant虚拟机来编译适合Centos的客户端安装包。编译成功后将生成一个tar格式的安装包，我们用这个tar包在centos里进行安装。没有相应的RPM安装包。
3.1 Clone Calamari客户端项目源码
Clone Calamari客户端项目源码，与Calamari服务端项目源码放在同个一目录下。
# git clone https://github.com/ceph/calamari-clients.git

由于ubuntu precise在后面的vagrant up时会导致：python-requests : Depends: python-urllib3 (>= 1.7.1) but it is not installable 错误，所以不采用源码里的12.04 precise版本，改为采用14.04 trusty版。
修改Vagrantfile为：
config.vm.box = "boxcutter/ubuntu1404"
config.vm.box_url = "file:///root/work/ubuntu1404.box"
并下载对应的ubuntu 14.04 box文件 放到/root/work目录下。
vagrant up时还会触发无法安装tornado的错误，解决办法：先查看../urllib-bootstrap-salt.sh，下载URL后的https://raw.githubusercontent.com/saltstack/salt-bootstrap/stable/bootstrap-salt.sh保存为bootstrap-salt.sh，再按下面两行修改Vagrantfile中对应位置内容。
salt.bootstrap_script = "../bootstrap-salt.sh"
salt.bootstrap_options = "-P"

错误信息表明没有需要的/git/calamari-clients*tar.gz文件，该文件要在运行salt-call state.highstate前先编译出来。编译方法：
sudo chown -R vagrant:vagrant ~/.npm
cd /git/calamari-client
export REAL_BUILD=y
make
make build-product
编译完成后会在/git/calamari-client下生成calamari-clients-build-output.tar.gz文件。将该文件复制到/git。

4.1.3. 停用防火墙和禁用SElinux
在测试环境可以直接停用防火墙，如果是生产环境则要建立相应iptable规则放行相应的WEB端口(通常是80):
停用防火墙使用命令：
sudo systemctl disable firewalld
sudo systemctl stop firewalld
同时还要禁用SElinux（生产环境不停用而是创建相应安全规则）
sudo sed -i s'/SELINUX=enforcing/SELINUX=disabled'/g /etc/sysconfig/selinux
4.1.4 初始化Calamari服务器

给出用于登录到Calamari控制面板的用户名和口令。
4.1.5 登录Calamari控制面板
打开浏览器输入Calamari服务器的IP地址打开Calamari控制面板登录页面，输入在上一步聚里给出的用户名和口令登录。
4.2. 将被监控的Ceph集群节点添加到Calamari控制面板
4.2.1 在被监控的Ceph节点上安装Diamond
sudo yum install -y diamond-3.4.67-0.noarch.rpm
sudo chkconfig diamond on
4.2.2 创建一个默认的Diamond配置文件
sudo mv /etc/diamond/diamond.conf.example /etc/diamond/diamond.conf
4.2.3 安装salt-minion
sudo yum install -y salt-minion
sudo systemctl enable salt-minion
4.2.4 修改salt-minion配置文件
修改/etc/salt/minion，内容为：
master: admin
admin为Calamari服务器的主机名，在Ceph节点主机的/etc/hosts中已配置。
4.2.5 启动服务
sudo systemctl start salt-minion
sudo systemctl start diamond
4.3 授权添加Ceph节点
当配置完所有Ceph集群节点后，需要在Calamari服务器上接受Ceph节点的salt key。
4.3.1 查看可接受的Ceph节点
在Calamari服务器上执行：
$ sudo salt-key -L
