puppet-dashboard 安装（草稿）

2022-06-14 12:20:04

接着上面的puppet安装一文，虽然puppet会很努力的工作，但还有个问题，我们想了解puppet节点的运行情况，也就是回馈，因为编写puppet语法规则难免出错。但是report目录下的yaml 文件又不具有可读性，客户端很多则邮件又会被淹没，于是这就有了dashboard。

dashboard 跟cacti 有点类似，都使用mysql作为后端数据库。
沿袭前面文章的环境
centos 6
服务端 puppet .test.org
客户端 apache01.test.org
已经配置好了http + passenger


安装dashboard

yum install puppetlabs-release
yum install puppet-dashboard mysql-server ruby-mysql
配置mysql数据库

# service mysqld start


# mysql -u root -p


mysql> CREATE DATABASE dashboard_production CHARACTER SET utf8;



>CREATE USER 'dashboard'@'localhost' IDENTIFIED BY 'dashboard';




>GRANT ALL PRIVILEGES ON dashboard_production.* TO 'dashboard'@'localhost';



> flush privileges;
















编辑/usr/share/puppet-dashboard/config/database.yml，修改如下

production:



  database: dashboard_production




  username: dashboard




  password: dashboard




  encoding: utf8




  adapter: mysql














导入数据

# cd /usr/share/puppet-dashboard/


# rake gems:refresh_specs


# rake RAILS_ENV=production db:create


# rake RAILS_ENV=production db:migrate














启动puppet-dashboard

2







chmod 666 /usr/share/puppet-dashboard/log/production.log



service  puppet-dashboard start














这样，puppet-dashboard 就会监听在本地3000端口，使用的是ruby自带的http服务器webrick，可以通过web浏览了。




apache作为前端


配置httpd虚拟主机









1







cp /usr/share/puppet-dashboard/ext/passenger/dashboard-vhost.conf /etc/httpd/conf.d/dashboard.conf













配置文件同样是给debian/ubuntu 用的，需要做一些修改






1、将日志选项路径 /var/log/apache2 改为/var/log/httpd



2、取个puppet主机的子域名 dashboard.puppet.test.org



3、模块路径由





  1. 

    /var/lib/gems/1.8/gems/passenger-2.2.11/ext/apache2/mod_passenger.so  
    



修改为





  1. 

    /usr/lib64/httpd/modules/mod_passenger.so 
    



4、passenger路径替换，将





  1. 

    /var/lib/gems/1.8/gems/passenger-2.2.11 
    



修改为





  1. 

    /usr/lib/ruby/gems/1.8/gems/passenger-3.0.12 
    



（版本号可能有差异，请事先查看是否存在类似的目录）



(其实之前已经配置了passenger，所以这行导入模块可以注释掉)



修改后大概就是这个样子(前3行可以注释掉)






    

  1. 

    # LoadModule passenger_module /usr/lib64/httpd/modules/mod_passenger.so 
    

    2. 

  2. 

    # PassengerRoot /usr/lib/ruby/gems/1.8/gems/passenger-3.0.12 
    

    3. 

  3. 

    # PassengerRuby /usr/bin/ruby 
    

    4. 

  4. 

    # you may want to tune these settings 
    

    5. 

  5. 

    PassengerHighPerformance on 
    

    6. 

  6. 

    PassengerMaxPoolSize 12 
    

    7. 

  7. 

    PassengerPoolIdleTime 1500 
    

    8. 

  8. 

    # PassengerMaxRequests 1000 
    

    9. 

  9. 

    PassengerStatThrottleRate 120 
    

    10. 

  10. 

    RailsAutoDetect On 
    

    11. 

  11. 

    <VirtualHost *:80>
    

    12. 

  12. 

            ServerName dashboard.puppet.test.org 
    

    13. 

  13. 

            DocumentRoot /usr/share/puppet-dashboard/public/ 
    

    14. 

  14. 

    <Directory /usr/share/puppet-dashboard/public/>
    

    15. 

  15. 

                    Options None 
    

    16. 

  16. 

                    Order allow,deny 
    

    17. 

  17. 

                    allow from all 
    

    18. 

  18. 

    </Directory>
    

    19. 

  19. 

      ErrorLog /var/log/httpd/dashboard.puppet.test.org_error.log 
    

    20. 

  20. 

      LogLevel warn 
    

    21. 

  21. 

      CustomLog /var/log/httpd/dashboard.puppet.test.org_access.log combined 
    

    22. 

  22. 

      ServerSignature On 
    

    23. 



重启httpd





  1. 

    service httpd restart 
    



实时报告


设置puppet客户端每次执行完任务后立即报告给dashboard


在apache01.test.org上设置puppet客户端





    

  1. 

    [agent] 
    

    2. 

  2. 

    report = true
    

    3. 



在puppet.test.org 上设置puppet服务端





    

  1. 

    [master] 
    

    2. 

  2. 

    reports = store,http
    

    3. 

  3. 

    reporturl = http://dashboard.puppet.test.org:80/reports 
    

    4. 



导入现有yml文件报告





  1. 

    #rake RAILS_ENV=production reports:import REPORT_DIR=/var/lib/puppet/ 
    




最后一步





  1. 

    cp /usr/share/puppet-dashboard/ext/puppet/puppet_dashboard.rb /var/lib/puppet/reports/ 
    



启动服务





    

  1. 

    # /etc/init.d/puppet-dashboard start 
    

    2. 

  2. 

    # /etc/init.d/puppet-dashboard-workers start 
    

    3.
