puppet 横向扩展(三)

概述
横向扩展实验之三 – 将CA 认证服务和 puppetmaster 分开
实验环境
master 和 node 都是 debian 7.7 i686 系统
2个 puppet master 在机器A 上, 都是 apache 虚拟主机
1个 CA 认证服务在 机器B 上.
实验步骤
机器B 的配置
# 清除 ca-1 上的既有证书
root@ca-1:~# rm -rf /var/lib/puppet/ssl/
# 在机器A 上认证 ca-1
# 补充: master-1 的IP就是 192.168.1.100
# 补充: ca-1 作为agent 连接master-1, 需要配置 /etc/hosts 和 /etc/puppet/puppet.conf
root@ca-1:/var/lib/puppet# puppet agent --test --server=192.168.1.100

机器A 的配置

机器B 配置好之后, 修改 apache 的配置, 使之将 CA认证服务指向机器B上的 ca-1
重要的地方, 我加了 #!!! 的注释
