在Ubuntu12.04上安装Ceph Calamari

Published on:
Tags: ubuntu ceph calamari

Calamari是Ceph的一个监控和管理工具，它提供了一些定义好的REST API。Calamari包括服务端和客户端，服务端是使用Python的web框架Django开发的，提供了供客户端调用的REST API接口。客户端使用了NodeJS,AngularJS,Bootstrap3，每个模块可以独立部署更新，其界面十分简洁清晰，几乎涵盖了所有监控要求。

下面介绍一下Calamari在Ubuntu上面的安装过程。

  • 这里的虚拟机将我们创建的根目录calamari-node和虚拟机中的/git目录关联起来了，我们可以通过在查看这2个目录中的任意一个来查看安装文件是否已经生成。

  • 从上面可以看到安装文件已经生成好了，2个deb文件分别是server和监控服务的安装文件，tar.gz文件是安装服务所需的依赖包安装文件集合，如果是连网安装的话，这个tar.gz文件不需要用到。

生成client安装文件

  • 下载calamari-client工程
1
2
$ cd calamari-node
$ git clone https://github.com/ceph/calamari-clients.git
  • 使用vagrant生成client安装文件

  • 查看生成的安装文件，可以看到有1个deb文件和一个tar.gz文件，ubuntu的话直接使用deb文件进行安装就可以了，tar.gz文件不需要。

安装Calamari

  • 创建一个ubuntu的虚拟机来安装calamari，首先在根目录下创建一个Vagrantfile文件。
1
2
$ cd calamari-node
$ touch Vagrantfile
  • Vagrantfile文件内容如下，注意要使用绑定好的IP。

VAGRANTFILE_API_VERSION = "2"

Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
  config.vm.box = "precise64"

  config.vm.define "manager" do |manager|
    manager.vm.hostname = "manager-env"

      vb.memory = 512
    end
  end
end
  • 启动虚拟机并登陆
1
2
$ vagrant up
$ vagrant ssh
  • 在虚拟机上安装salt

$ sudo apt-get install python-software-properties
$ sudo add-apt-repository ppa:saltstack/salt
$ sudo apt-get update
$ sudo apt-get install salt-master
$ sudo apt-get install salt-minion
  • 在虚拟机上安装所需依赖包
1
$ sudo apt-get update && sudo apt-get install -y apache2 libapache2-mod-wsgi libcairo2 supervisor python-cairo libpq5 postgresql
  • 安装calamari
1
2
$ cd /vagrant
$ sudo dpkg -i calamari-server*.deb calamari-clients*.deb
  • 初始化calamari服务，这里会要求你输入用户名、邮箱、密码，这个用户名密码是在浏览器访问calamari服务需要的。

  • 输入刚才设置的用户名密码后，可以看到calamari提示你进行ceph集群配置。

Ceph集群配置监控服务

配置ceph集群

  • 登陆其中一台ceph集群机器(这里假设ceph集群都是ubuntu环境)，安装监控服务。
1
$ sudo dpkg -i diamond_3.4.67_all.deb #deb文件是之前生成server安装文件时一起生成的，需要将其先考到ceph集群机器上
  • 创建默认的监控配置文件
1
$ sudo mv /etc/diamond/diamond.conf.example /etc/diamond/diamond.conf
  • 安装salt-minion服务
1
2
3
4
$ sudo apt-get install python-software-properties
$ sudo add-apt-repository ppa:saltstack/salt
$ sudo apt-get update
$ sudo apt-get install salt-minion
  • 在/etc/hosts文件中增加calamari服务器的映射关系
/etc/hosts
1
2
3
...
...
192.168.26.10 ceph-calamari
  • 修改salt-minion的配置文件/etc/salt/minion，将master指向calamari服务器
/etc/salt/minion
1
2
3
...
master: ceph-calamari
...
  • 重启服务
1
2
$ sudo service salt-minion restart  
$ sudo service diamond restart
  • 在所有的ceph集群机器上重复以上的步骤。

在calamari服务上添加ceph集群机器

  • 查看salt-key
