puppet学习—httpd+passenger安装DashBoard

wdcsx

　　DashBoard启动默认使用WEBRcik服务器，WEBRcik服务器有助于快速运行DashBoard服务器，但性能无法进行扩展，当有大量的报告时，性能会急剧下降。这时可以使用Passenger服务器运行DashBoard。DashBoard 安装在master.test.com。并且在客户端配置文件做如下配置
　　#vim /etc/puppet/puppet.conf
　　[agent]
　　report = true
　　一、安装依赖软件包
　　#rpm -ivh http://yum.puppetlabs.com/el/6Server/products/x86_64/puppetlabs-release-6-6.noarch.rpm
　　#yum -y install mysql mysql-devel mysql-server ruby ruby-devel ruby-irb ruby-mysql ruby-rdoc ruby-ri rubygems
　　#gem install rake
　　二、安装DashBoard软件包
　　#yum install -y  puppet-dashboard
　　三、配置DashBoard
　　1创建数据库
　　#vim /etc/my.cnf
　　max_allowed_packet = 32M
　　#service mysqld start
　　#chkconfig mysqld on
　　#mysql
　　mysql>create database dashboard CHARACTER SET utf8;

　　mysql>create user 'dashboard'@'localhost'>　　mysql>grant all privileges on dashboard.* TO 'dashboard'@'localhost';
　　mysql>flush privileges;
　　2修改配置文件
　　#vim /usr/share/puppet-dashboard/config/database.yml
　　production:
　　database: dashboard
　　username: dashboard
　　password: dashboard
　　encoding: utf8
　　adapter: mysql
　　#vim /usr/share/puppet-dashboard/config/settings.yml
　　time_zone: 'Asia/Shanghai'
　　3导入数据库
　　#cd /usr/share/puppet-dashboard/config
　　#rake RAILS_ENV=production db:migrate
　　四、配置httpd passenger
　　#yum install httpd mod_passenger
　　#vim /etc/httpd/conf.d/passenger.conf
　　LoadModule passenger_module modules/mod_passenger.so
　　<IfModule mod_passenger.c>
　　PassengerRoot /usr/share/rubygems/gems/passenger-3.0.17
　　PassengerRuby /usr/bin/ruby
　　PassengerMaxPoolSize 6         #passenger启动的线程数，通常为cpu核心个数的1.5倍
　　PassengerPoolIdleTime 40000    #passenger接受的最大请求数
　　PassengerStatThrottleRate 120  #关闭空闲超过1800秒的passenger实例
　　RailsAutoDetect On
　　</IfModule>
　　<VirtualHost *:80>
　　ServerName master.test.com
　　DocumentRoot "/usr/share/puppet-dashboard/public/"
　　<Directory "/usr/share/puppet-dashboard/public/">
　　Options None
　　AllowOverride AuthConfig
　　Order allow,deny
　　allow from all
　　</Directory>
　　ErrorLog /var/log/httpd/dashboard_error.log
　　LogLevel warn
　　CustomLog /var/log/httpd/dashboard_access.log combined
　　ServerSignature On
　　</VirtualHost>
　　#service httpd start
　　#chkconfig httpd on
　　五、导入现有报告
　　#cd /usr/share/puppet-dashboard
　　#rake RAILS_ENV=production reports:import
　　六、配置实时发送报告
　　#vim /etc/puppet/puppet.conf
　　reports = store,tagmail,log,puppet_dashboard,http
　　reporturl = http://172.16.30.220/reports
　　七、开启报告
　　#rake RAILS_ENV=production jobs:work 2 &>1 &
　　八、访问dashboard
　　http://172.16.30.220/reports
