Puppet之puppet dashboard安装
环境：[*]ubuntu 10.04
[*]puppet master server已经安装完成
[*]Ruby or Ruby Enterprise Edition version 1.8.7 — Dashboard 1.2 no longer supports older versions of Ruby, and Ruby 1.9.2 is not yet fully supported.
[*]RubyGems
[*]Rake version 0.8.3 or newer
[*]MySQL database server version 5.x
[*]Ruby-MySQL bindings version 2.7.x or 2.8.x
安装：
[*]安装operating system packages
[*]apt-get install -y build-essential irb libmysql-ruby libmysqlclient-dev \
[*] libopenssl-ruby libreadline-ruby mysql-server rake rdoc ri ruby ruby-dev
[*]使用script 安装 RubyGems package
[*]URL="http://production.cf.rubygems.org/rubygems/rubygems-1.3.7.tgz"
[*]PACKAGE=$(echo $URL | sed "s/\.[^\.]*$//; s/^.*\///")
[*]
[*]cd $(mktemp -d /tmp/install_rubygems.XXXXXXXXXX) && \
[*]wget -c -t10 -T20 -q $URL && \
[*]tar xfz $PACKAGE.tgz && \
[*]cd $PACKAGE && \
[*]sudo ruby setup.rb
[*]创建链接代替gem1.8
[*]update-alternatives --install /usr/bin/gem gem /usr/bin/gem1.8 1
[*] Installing Dashboard
[*]$ sudo apt-get update
[*]sudo vim /etc/puppet-dashboard/database.yml
[*]$ sudo apt-get install puppet-dashboard
[*]配置mysql数据库
我自己用apt装完Dashboard发现相关数据库的配置并没有自动生成，需要手动配置。
[*]#--创建数据库--
[*]$ sudo mysql -uroot -p（密码）
[*]mysql> create database dashboard default charset utf8;
[*]Query OK, 1 row affected (0.00 sec)
[*]mysql> use dashboard
[*]Database changed
[*]mysql> grant all on dashboard.* to dashboard@localhost identified by ‘dashboard’ ;
[*]Query OK, 0 rows affected (0.02 sec)
[*]mysql> flush privileges;
[*]Query OK, 0 rows affected (0.00 sec)
[*]#--数据库优化
[*]$ sudo vim /etc/mysql/my.cnf
[*]max_allowed_packet= 32M
[*]修改database.yml
[*]sudo vim /etc/puppet-dashboard/database.yml
[*]production: database: dashboard username: dashboard password: mysql encoding: utf8 adapter: mysql
[*]使用rake任务创建刚从在config / database.yml文件设置的数据库
[*]$sudo rake RAILS_ENV=production db:create
[*]$sudo gem install mysql
[*]$sudo rake RAILS_ENV=production db:migrate（为典型的生产环境配置）
[*] 启动dashboard
[*]$cd /usr/share/puppet-dashboard/
[*]$sudo ./script/server -e production -d
[*]#可以使用script/server –help查看更详细的用法
[*]#可以使用http://ip:3000进行查看，ip为安装dashboard的机器更多操作的图就不显示出来了。
[*] dashboard server(master) 配置
[*]# puppet.conf (on puppet master)
[*]
[*]# These are needed when the puppetmaster is run by passenger
[*]# and can safely be removed if webrick is used.
[*]ssl_client_header = SSL_CLIENT_S_DN
[*]ssl_client_verify_header = SSL_CLIENT_VERIFY
[*]reports = store, http
[*]reporturl = http://127.0.0.1:3000/reports/upload
[*]agent 配置
[*]# puppet.conf (on each agent)
[*]
[*] report = true
[*]在dashboard主机上再执行
[*]cp /usr/local/puppet-dashboard/ext/puppet/puppet_dashboard.rb /usr/lib/ruby/site_ruby/1.8/puppet/reports/
[*]rake RAILS_ENV=production reports:import导入日志
[*]使用监控脚本
[*]sudo env RAILS_ENV=production /usr/share/puppet-dashboard/script/delayed_job -p dashboard -n 4 -m start
所有配置完成后重启相应的服务，登录http://ip:3000，查看效果。
