puppet安装部署，实例JDK和tomcat

puppet 原理和工作流程

puppet 一个为实现数据中心自动化管理而设计的配置管理软件

基于C/S架构

原理：S服务端保存着所有的对客户端服务器的配置代码，puppet里叫清单（manifest)；c客户端下载清单后，根据清单对服务器进行配置

工作流程：客户端调用facter facter探测出主机的一些变量，puppetd 把这些信息通过SSL连接发送到服务器puppetmaster

服务器puppetmaster 检测客户端的主机名，然后找到manifest里面对应主机的配置，对其解析，让客户端执行。客户端每隔30分钟同步一次配置文件。

puppet安装

centos6.5 安装puppet

    OS: Centos 6.5 x86_64

    Puppet master: master.com (192.168.116.135)

    Puppet clients: client1.com (192.168.116.136)

    Puppet clients: client2.com (192.168.116.137)

一、先做好安装的准备工作：

1. 在master和client均关闭selinux，iptables：

停止iptables

[[email protected] ~]# service iptables stop

[[email protected] ~]# chkconfig  ptables off

关闭selinux

[[email protected] ~]# vim /etc/selinux/config

改成 SELINUX=disabled

2. 为了保证能向master主机申请到正确的有效证书，建议master和client设置ntp：

[[email protected] ~]#  yum -y install ntp

[[email protected] ~]#  ntpdate pool.ntp.org

[[email protected] ~]#  chkconfig ntpd on

[[email protected] ~]# chkconfig --list|grep ntp

[[email protected] ~]# service ntpd start

3. 在master和client端设置主机名和hosts

Puppet 要求所有机器有完整的域名，如果没有 DNS 服务器提供域名的话，可以在机器上设置主机名

[[email protected] ~]# vim /etc/sysconfig/network

master.com

[[email protected] ~]# vim /etc/hosts

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4

 ::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

 192.168.116.135 master.com

 192.168.116.136 client1.com

 192.168.116.137 client2.com

4.  安装puppet官方源(都安装后，克隆改主机名)

[[email protected] ~]# wget http://yum.puppetlabs.com/el/6/products/x86_64/puppetlabs-release-6-7.noarch.rpm

[[email protected] ~]# rpm -ivh puppetlabs-release-6-7.noarch.rpm

[[email protected] ~]# yum update

之上C/S都安装

二、Master端安装配置

1. 安装 puppet-server

[[email protected] ~]# yum -y install puppet-server

2. 添加自动签发证书

编辑 /etc/puppet/puppet.conf 文件， 在[main]段内加入 autosign = true，server = master.com

[[email protected] ~]# vim /etc/puppet/puppet.conf

[main]

     # The Puppet log directory.

     # The default value is ‘$vardir/log‘.

     logdir = /var/log/puppet

     # Where Puppet PID files are kept.

     # The default value is ‘$vardir/run‘.

     rundir = /var/run/puppet

     # Where SSL certificates are kept.

     # The default value is ‘$confdir/ssl‘.

     ssldir = $vardir/ssl

     autosign = true

     server = master.com

3. 启动Puppetmaster

[[email protected] ~]# service puppetmaster start

[[email protected] ~]#  netstat -tunlp | grep :8140

tcp        0      0 0.0.0.0:8140                0.0.0.0:*                   LISTEN      9148/ruby

4. 开机启动

[[email protected] ~]# chkconfig --list |grep puppet

[[email protected] ~]# chkconfig puppetmaster on

[[email protected] ~]# chkconfig --list |grep puppet

 

三、客户端安装配置

1.  puppet 安装

[[email protected] ~]# yum -y install puppet

2. 为客户端指定puppet服务器,并开启Master的推送功能

编辑 /etc/puppet/puppet.conf 文件，在[agent]段内加入 listen = true，server = master.com

[[email protected] ~]# vim /etc/puppet/puppet.conf

[agent]

     # The file in which puppetd stores a list of the classes

     # associated with the retrieved configuratiion.  Can be loaded in

     # the separate ``puppet`` executable using the ``--loadclasses``

     # option.

     # The default value is ‘$confdir/classes.txt‘.

     classfile = $vardir/classes.txt

     # Where puppetd caches the local configuration.  An

     # extension indicating the cache format is added automatically.

     # The default value is ‘$confdir/localconfig‘.

     localconfig = $vardir/localconfig

     listen = true

     server = master.com

编辑 /etc/puppet/auth.conf 文件， 在 auth / 最下面加入以下语句

[[email protected] ~]# vim /etc/puppet/auth.conf

path /run

 method save

 allow master.com

3. 启动client

[[email protected] ~]# service puppet start

[[email protected] ~]#  netstat -tunlp | grep :8139

4. 开机启动

[[email protected] ~]# chkconfig puppet on

[[email protected] ~]# chkconfig --list |grep puppet

测试

[[email protected] ~]#puppet agent --test

[[email protected] ~]#puppet cert list --all

在服务端安装puppet的dashboard

安装mysql

 [[email protected] ~]# yum install  ruby-mysql mysql-server puppet-dashboard

优化mysql设置

[[email protected] ~]# cp /usr/share/mysql/my-large.cnf  /etc/my.cnf

[[email protected] ~]# vim /etc/my.cnf

[mysqld]

max_allowed_packet = 32M

启动Mysql服务

[[email protected] ~]# service mysqld start

[[email protected] ~]# chkconfig mysqld on

[[email protected] ~]# chkconfig --list |grep mysqld

[[email protected] ~]# mysqladmin -u root password ‘123456‘

创建一个dashboard数据库

[[email protected] ~]# mysql -uroot -p123456 <<EOF

 > CREATE DATABASE dashboard CHARACTER SET utf8;

 > CREATE USER ‘dashboard‘@‘localhost‘ IDENTIFIED BY ‘123456‘;

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

 > FLUSH PRIVILEGES;

 > EOF

配置Dashboard

[[email protected] ~]# vim /usr/share/puppet-dashboard/config/database.yml

production:

database: dashboard

username: dashboard

password: 123456

encoding: utf8

adapter: mysql

修改时区

[[email protected] ~]# vim /usr/share/puppet-dashboard/config/environment.rb

config.time_zone=‘Beijing‘

初始化数据库

[[email protected] ~]# cd /usr/share/puppet-dashboard/

 [[email protected] puppet-dashboard]# rake RAILS_ENV=production db:migrate

[[email protected] ~]# service httpd stop

[[email protected] ~]# service puppetmaster start 

[[email protected] ~]# service puppet-dashboard start

 访问http://master.com:3000 

导入报告

cd /usr/share/puppet-dashboard

rake RAILS_ENV=production reports:import

执行报告

cd /usr/share/puppet-dashboard

rake jobs:work RAILS_ENV="production"

例子：

[[email protected] ~]# mkdir -p /etc/puppet/modules/motd{files,manifests,templates}

[[email protected] ~]# cd /etc/puppet/modules/motd/files

[[email protected] ~]# mkdir etc

[[email protected] ~]# vim motd
