puppet-dashboard安装及用apache和nginx进行管理

puppet dashboard是GUI（图形用户界面）方式管理puppet，可以分析puppet运行日志。一、安装：
1、添加第三方包仓库EPEL：
rpm -Uvh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm 2、安装ruby环境：
yum -y install ruby ruby-devel ruby-irb ruby-rdoc ruby-ri ruby-libs ruby-rdoc openssl-devel 3、安装dashboard依赖包：
yum install -y mysql mysql-devel mysql-server ruby-mysql 6、安装dashboard
wget http://downloads.puppetlabs.com/dashboard/puppet-dashboard-1.2.23.tar.gz tar xf puppet-dashboard-1.2.23.tar.gz mv puppet-dashboard-1.2.23 /usr/local/dashboard 7、启动mysql
service mysqld start二、配置dashboard： 1、编辑database.yml来指定数据库：
cd /usr/local/dashboard vim config/database.yml

production: database: dashboard username: dashboard password: dashboard encoding: utf8 adapter: mysql

2、使用rake命令基于database.yml来创建数据库dashboard： rake RAILS_ENV=production db:create（如果报错，就手动创建数据库）注：如果使用rake报错：rake aborted!undefined method `source_index' for Gem:Module可能是gem版本过高或者过低导致，解决办法：gem update --system 1.8.25

mysql -uroot -pmysql> create database dashboard default charset utf8;mysql>use dashboard;mysql>grant all on dashboard.* to dashboard@localhost identified by 'dashboard' ;mysql>flush privileges; mysql>exit

3、填充数据库：
rake RAILS_ENV=production db:migrate
4、修改dashboard的显示时区，默认为UTC，改为北京：vim config/environment.rb

config.time_zone = "Beijing"

三、启动dashboard： 1、启动dashboard日志分析进程 env RAILS_ENV=production /usr/local/dashboard/script/delayed_job -p dashboard -n 4 -m start 2、检查分析进程是否启动 ps -ef|grep delayed_job|grep -v grep 3、启动dashboard的GUI界面webrick（注：此方法不被推荐，建议使用apache+passenger或nginx+passenger来运行）
/usr/local/dashboard/script/server -e production 通过http://ip:3000访问测试。四、使用apache+Passenger运行puppet-dashboard： passenger比webrick复杂很多，也比webrick具有更好的性能，还能和apache或nginx组合在一起。
1、安装apache：
yum install -y httpd httpd-devel 2、安装rubygems
wget http://rubyforge.org/frs/download.php/76729/rubygems-1.8.25.tgz tar xf rubygems-1.8.25.tgz cd rubygems-1.8.25 ruby setup.rb 3、修改gem的源仓库 gem sources -l 查看gem源 gem sources -a http://ruby.taobao.org/ 添加国内镜像源
gem sources --remove http://rubygems.org/ 删除国外源 4、安装passenger： gem install passenger 5、创建apache passenger模块：
passenger-install-apache2-module 6、配置apache主配置文件httpd.conf，添加如下内容：

LoadModule passenger_module /usr/lib/ruby/gems/1.8/gems/passenger-4.0.10/buildout/apache2/mod_passenger.so PassengerRoot /usr/lib/ruby/gems/1.8/gems/passenger-4.0.10 PassengerRuby /usr/bin/ruby PassengerHighPerformance on #PassengerUseGlobalQueue on #该选项在已被废弃 PassengerMaxPoolSize 6 #passenger启动的线程数，通常为cpu核心个数的1.5倍 PassengerMaxRequests 4000 #passenger接受的最大请求数 PassengerPoolIdleTime 1800 #关闭空闲超过1800秒的passenger实例<VirtualHost *:80> ServerName dashboard.cmmobi-wh.com DocumentRoot /usr/local/dashboard/public/ <Directory /usr/local/dashboard/public/> # This relaxes Apache security settings. AllowOverride all # MultiViews must be turned off. Options -MultiViews </Directory></VirtualHost>

7、启动apache： service httpd restart
五、使用Nginx+Passenger运行puppet-dashboard： 1、编译安装nginx，加上passenger模块： ./configure --add-module=/usr/lib64/ruby/gems/1.8/gems/passenger-4.0.10/ext/nginx 2、修改nginx配置文件如下：

http { ... passenger_root /usr/lib64/ruby/gems/1.8/gems/passenger-4.0.10; passenger_ruby /usr/bin/ruby; ... } server { listen 80; server_name www.dashboard.com; root /usr/local/dashboard/public; passenger_enabled on; }

六、汇总显示报告： 1、导入现有report：
cd /usr/local/dashboard rake RAILS_ENV=production reports:import 2、实时导入report：
puppet client端编辑/etc/puppet/puppet.conf

[agent] report = true

puppet master端编辑/etc/puppet/puppet.conf

reports = http,store reporturl = http://172.16.5.156:80/reports

service puppetmaster restart service puppet restart七、数据库维护： 1、当puppet dashboard数据量过多的时候，需要优化数据库，可使用命令： rake RAILS_ENV=production db:raw:optimize 2、清理dashborad一个月之前的数据： rake RAILS_ENV=production reports:prune upto=1 unit=mon 3、备份puppet dashborad数据库： rake RAILS_ENV=production FILE=/my/backup/file.sql db:raw:dump 4、恢复数据：
rake RAILS_ENV=production FILE=production.sql db:raw:restore
