二、Puppet介绍

Puppet是IT自动化的行业标准。 以一种简单而强大的方式管理和自动化更多的基础架构和复杂的工作流。

三、Puppet安装

安装准备

master和node端

# 修改主机名
hostnamectl set-hostname master

#配置域名解析
 vim /etc/hosts
192.168.200.11  master
192.168.200.12  node

#关闭防火墙
systemctl stop firewalld
systemctl disable firewalld

#关闭SELinux安全模式
setenforce 0
sed -i 's/SELINUX=.*/SELINUX=disabled/g' /etc/selinux/config

#配置时间同步
yum install -y ntpdate
ntpdate ntp1.aliyun.com

#配置CentOS镜像源
curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo

sed -i -e '/mirrors.cloud.aliyuncs.com/d' -e '/mirrors.aliyuncs.com/d' /etc/yum.repos.d/CentOS-Base.repo

#更新YUM源
yum clean all
yum makecache

#升级系统
yum update

安装master端

安装、配置并使用Puppet | Puppet运维实战

# 安装阿里云仓库
rpm -ivh https://mirrors.aliyun.com/puppet/yum/puppetlabs-release-el-7.noarch.rpm

# 安装Puppet-server、puppet和facter
yum install -y puppet puppet-server facter

# 备份配置文件
cp /etc/puppet/puppet.conf{,.bak} 

# 配置puppet.conf
[root@master puppet]# vim puppet.conf
[root@master puppet]# cat puppet.conf

    # The Puppet log directory.
    # The default value is '$vardir/log'.
    logdir = /var/log/puppet

    # The default value is '$vardir/run'.
    rundir = /var/run/puppet

    # Where SSL certificates are kept.
    # The default value is '$confdir/ssl'.
    ssldir = $vardir/ssl

    # associated with the retrieved configuratiion.  Can be loaded in
    # the separate ``puppet`` executable using the ``--loadclasses``

# 启动puppetmaster服务
systemctl start puppetmaster
systemctl enable puppetmaster
