介绍
foreman是一个puppet的生命周期管理系统，类似puppet-dashboard，通过它可以很直观的查看puppet所有客户端的同步状态与facter参数，当前只有Ohad Levy, Frank Sweetser, Paul Kelly三位在默默无闻的管理开发这个项目，更多资料请参见foreman官方站：http://theforeman.org

本文介绍下foreman安装步骤,供各位研究puppet的朋友参考之用。

系统环境：CentOS5.4
yum源: 光盘iso、dag-rpmforge、fedora-epel (mirrors.sohu.com)
puppet版本：puppet-0.25.4.rpm

前提准备
安装rake
yum install rubygem-rake rubygem-rack-1.0.1-1 rubygem-sqlite3-ruby
下载foreman最新tar包
cd /opt
http://theforeman.org/p_w_uploads/download/104/foreman-0.1-5.tar.bz2
tar -jxf foreman-0.1-5.tar.bz2
也可以通过git下载
cd /opt
git clone git://github.com/ohadlevy/foreman.git foreman
cd foreman
git submodule init
git submodule update
复制foreman-report脚本
cp extras/puppet/foreman/files/foreman-report.rb /usr/lib/ruby/site_ruby/1.8/puppet/reports/foreman.rb
添加foreman用户
useradd foreman -d /opt/foreman -M -s /sbin/nologin

安装foreman
cd /opt/foreman
rake Rakefile && rake
# foreman默认使用sqlite数据库，不需要改动数据库配置，如果你更喜欢MySQL的话，请手动创建foreman、foremandevel、foremantest三个库，然后修改数据库配置文件 foreman/config/database.yml 为以下内容。
production:
    adapter: mysql
    database: foreman
    username: root
    password:
    host: localhost
    socket: "/var/lib/mysql/mysql.sock"
development:
    adapter: mysql
    database: foremandevel
    username: root
    password:
    host: localhost
    socket: "/var/lib/mysql/mysql.sock"
test:
    adapter: mysql
    database: foremantest
    username: root
    password:
    host: localhost
    socket: "/var/lib/mysql/mysql.sock"

建立数据库表结构
RAILS_ENV=production rake db:migrate
导入节点与facter信息
# This will import your facts (only new facts) every time you run the script.
rake puppet:import:hosts_and_facts RAILS_ENV=production
# This will create all required settings from your facts.
rake puppet:migrate:populate_hosts RAILS_ENV=production

创建服务文件 /etc/sysconfig/foreman
# the location where foreman is installed
#FOREMAN_HOME=/usr/share/foreman

# the port which foreman web server is running at
# note that if the foreman user is not root, it has to be a > 1024
#FOREMAN_PORT=3000

# the user which runs the web interface
#FOREMAN_USER=foreman

# the rails environment in which foreman runs
#FOREMAN_ENV=production

创建服务启动脚本 /etc/init.d/foreman
#!/bin/bash
#
# Init script for foreman
#
# chkconfig: - 85 15
# description: Init script for foreman

# Source function library.
. /etc/rc.d/init.d/functions

if [ -f /etc/sysconfig/foreman ]; then
        . /etc/sysconfig/foreman
fi

prog=foreman
RETVAL=0
# open port 80 need root user
FOREMAN_PORT=${FOREMAN_PORT:-3000}
FOREMAN_USER=${FOREMAN_USER:-root}
FOREMAN_HOME=${FOREMAN_HOME:-/opt/foreman}
FOREMAN_ENV=${FOREMAN_ENV:-production}
FOREMAN_PID=${FOREMAN_PID:-${FOREMAN_HOME}/tmp/pids/server.pid}

start() {
        echo -n $"Starting $prog: "
     daemon --user ${FOREMAN_USER} /usr/bin/ruby ${FOREMAN_HOME}/script/server -p ${FOREMAN_PORT} -e ${FOREMAN_ENV} -d > /dev/null
#    daemon /usr/bin/ruby ${FOREMAN_HOME}/script/server -p 80 -e ${FOREMAN_ENV} -d >/dev/null
        RETVAL=$?
        if [ $RETVAL = 0 ]
        then
                echo_success
        else
                echo_failure
        fi

        echo
        return $RETVAL
}
stop() {
        echo -n $"Stopping $prog: "
        if [ -f ${FOREMAN_PID} ]; then
                killproc -p ${FOREMAN_PID}
                RETVAL=$?
        else
                echo -n $"Foreman was not running.";
                failure $"Foreman was not running.";
                echo
                return 1
        fi
        echo
        return $RETVAL
}

# See how we were called.
case "$1" in
        start)
                start
        ;;
        stop)
                stop
        ;;
        status)
                echo -n "Foreman"
                status -p $FOREMAN_PID
                RETVAL=$?
        ;;
        restart)
                stop
                start
        ;;
        *)
                echo $"Usage: $prog {start|stop|restart}"
                exit 1
esac

exit $RETVAL
chmod 755 /etc/init.d/foreman

修改puppetmaster的puppet.conf
reports=log, foreman

配置邮件报警 config/email.yaml
# Outgoing email settings
# config/email.yaml
production:
    delivery_method: :smtp
    smtp_settings:
        address: mail.example.com
        port: 25
        domain: example.com
        authentication: :none

修改基本配置 config/settings.yaml
:modulepath: /etc/puppet/modules/
:tftppath: tftp/
:rrd_report_url: report/
#:ldap: true
#your default puppet server - can be overridden in the host level
#if none specified, plain "puppet" will be used.
:puppet_server: puppet
:unattended: false
#use the following setting to override the default 30 minutes puppet run interval - value must be in minutes
:puppet_interval: 10
:document_root: /var/www
#:puppetrun: true
:administrator: admin@example.com
:failed_report_email_notification: true

启动服务
service foreman start
使用firefox、chrome浏览http://localhost:3000
