6.2. 将配置应用到现有客户端

您可能希望将 Puppet 配置应用到未通过 Red Hat Satellite 6 置备的现有客户端。在这种情况下，在将 Puppet 注册到红帽卫星 6 后，在现有客户端上安装和配置 Puppet。

将现有系统注册到 Red Hat Satellite 6。有关注册现有主机的详情，请参考 管理主机指南中的注册主机。https://access.redhat.com/documentation/zh-cn/red_hat_satellite/6.10/html/managing_hosts/registering_hosts

重要

puppet 软件包是 Red Hat Satellite Tools 6.10 软件仓库的一部分。在继续操作前，请确保启用此软件仓库。

要安装并启用 Puppet 代理：

打开终端控制台并以 root 用户身份登录。
安装 Puppet 代理：
```
yum install puppet
```
```
# yum install puppet
```

将 Puppet 代理配置为在引导时启动：
- 在 Red Hat Enterprise Linux 6 中：
  # chkconfig puppet on

- 在 Red Hat Enterprise Linux 7 上：
  # systemctl enable puppet

配置 Puppet 代理

通过更改 /etc/puppetlabs/puppet/puppet.conf 文件来配置 Puppet 代理：

vi /etc/puppetlabs/puppet/puppet.conf

# vi /etc/puppetlabs/puppet/puppet.conf

从卫星服务器，将 environment 参数设置为主机的 Puppet 环境。Puppet 环境标签包含组织标签、生命周期环境、内容视图名称和内容视图 ID。要在 Satellite 6 web UI 中查看 Puppet 环境列表，请导航到 Configure > Environments。

在主机上运行 Puppet 代理：

puppet agent -t --server satellite.example.com

# puppet agent -t --server satellite.example.com

通过 Satellite 服务器 Web 界面为 Puppet 客户端签名 SSL 证书：
1. 通过 Web 界面登录卫星服务器。
2. 选择 Infrastructure > Capsules。
3. 点所需主机右侧的证书。
4. 点 Sign。
5. 再次运行 puppet agent 命令：
  # puppet agent -t --server satellite.example.com
  Copy to Clipboard Toggle word wrap

注意

当在主机上配置 Puppet 代理时，它将列在 All Hosts 下，但只有选择为主机 的任何上下文 时，才会分配到组织或位置。
