自动化运维工具puppet（六）

一、Puppet DashBoard
1、简介
Puppet DashBoard是个Ruby on Rails程序， 简称DashBoard， 于显Puppet Master和Puppet Agent的相关信息。 它允许查看个或多个Puppet Master汇总的图和报告数据， 可以同时从个或多个Puppet Master上收集来Puppet Agent的所有数据信息， 并作为个ENC来管理Puppet节点， 主动触发Puppet Agent主动更新等。
2、安装DashBoard

[root@www.example.com ~]# yum install -y puppet-dashboard-1.2.23-1.el6.noarch.rpm
[root@www.example.com ~]# gem install rake

3、数据库创建及授权

MariaDB [(none)]> create database dashboard character set utf8;
Query OK, 1 row affected (0.30 sec)

MariaDB [(none)]> grant all privileges on dashboard.* to 'dashboard'@'localhost' identified by 'redhat';
Query OK, 0 rows affected (0.12 sec)

MariaDB [(none)]> grant all privileges on dashboard.* to 'dashboard'@'192.168.%.%' identified by 'redhat';
Query OK, 0 rows affected (0.00 sec)

MariaDB [(none)]> flush privileges;
Query OK, 0 rows affected (0.09 sec)

4、修改配置文件：

[root@www.example.com ~]# vim /usr/share/puppet-dashboard/config/database.yml
production:
host: 192.168.1.8
database: dashboard
username: dashboard
password: redhat
encoding: utf8
adapter: mysql

5、导入数据库

[root@www.example.com ~]# cd /usr/share/puppet-dashboard/config/
[root@www.example.com config]# rake gems:refresh_specs
[root@www.example.com config]# rake RAILS_ENV=production db:migrate

6、启动dashboard

[root@www.example.com ~]# /usr/share/puppet-dashboard/script/server -e production
=> Booting WEBrick
=> Rails 2.3.17 application starting on http://0.0.0.0:3000 => Call with -d to detach

7、配置puppet服务端和客户端
服务器端配置

# puppet.conf (on puppet master)
[master]
reports = store, http
reporturl = http://dashboard.example.com:3000/reports/upload[/code] 完成后重启puppetmaster服务。

在客户端配置
# puppet.conf (on each agent)
[agent]
report = true
完成后重启puppet服务。
而后打开dashboard，如果看到“# pending task”类的信息，且数字大于0，则表示已经正常接收报告了，一旦有用户任务延迟就会记录在dashboard中。 可以配置dashboard通过passanger和apache提供服务。
