安装

Server端

yum install -y puppetserver
service puppetserver start  # 有些用的是puppetmaster,如果启动报内存限制，那么修改配置/etc/sysconfig/puppetserver将 JAVA_ARGS="-Xms512m -Xmx512m"修改为JAVA_ARGS="-Xms2g -Xmx2g"

Client端

sudo rpm -Uvh https://yum.puppetlabs.com/puppetlabs-release-pc1-el-7.noarch.rpm # 这里要注意版本是6还是7
yum install -y puppet-agent

dashboard的安装

参考文章

# 首先得有数据库
create database puppetdash # 创建用户
grant all privileges on puppetdash.* to puppetdash@localhost identified by 'password';
flush privileges;

# 安装软件
rpm -ivh http://yum.puppetlabs.com/el/6/products/x86_64/puppetlabs-release-6-1.noarch.rpm
yum -y install puppet-dashboard

# 修改puppet-dashboard配置
cp /usr/share/puppet-dashboard/config/settings.yml.example /usr/share/puppet-dashboard/config/settings.yml
vim /usr/share/puppet-dashboard/config/database.yml 内容如下：
/usr/share/puppet-dashboard/config/database.yml
production:
 database: puppetdash
 username: puppdash
 password: motorrobot
 encoding: utf8
 adapter: mysql
development:
 database: puppetdash
 username: puppdash
 password: motorrobot
 encoding: utf8
 adapter: mysql

# 生成数据
cd /usr/share/puppet-dashboard
rake db:migrate
/etc/init.d/puppet-dashboard start

# 修改puppet的配置
vim /etc/puppet/puppet.conf # 添加内容
report = true
[master]
reports = store, http
reporturl = http://192.168.99.1:3000/reports/upload

# 启动服务
puppetd -t
chown puppet-dashboard /usr/share/puppet-dashboard/log/
chkconfig puppet-dashboard on
chkconfig puppet-dashboard-workers on
chkconfig mysqld on
/etc/init.d/puppet-dashboard restart
/etc/init.d/puppet-dashboard-workers restart

Hello World举例

1. 新建module

    cd /opt/puppetlabs/puppet/modules/
    mkdir -p helloworld/manifests/
   
    vim helloworld/manifests/init.pp # 内容如下：
    class helloworld {
        notify { 'hello, world!': }
    }
   
    vim helloworld/manifests/motd.pp # 内容如下：
    class helloworld::motd {
        file { '/etc/motd':
        owner  => 'root',
        group  => 'root',
        mode    => '0644',
        content => "hello, world!\n",
        }
     }
   

2. 将module添加到主配置文件

    cd /etc/puppetlabs/code/environments/production/manifests
    vim site.pp  # 内容如下：
    node default{
        class { 'helloworld': }
        class { 'helloworld::motd': }
    }
   

测试

分别在两个端启动puppet服务，然后客户端执行puppet agent -t
