红帽全球峰会3.4. 为系统设置主机名（Hostname）
director 的安装和配置过程需要一个完全限定域名（FQDN），这意味着您必须为 director 的主机设置主机名。使用以下命令检查主机的主机名：
hostname # Checks the base hostname hostname -f # Checks the long hostname (FQDN)
$ hostname # Checks the base hostname
$ hostname -f # Checks the long hostname (FQDN)
如果需要，使用
hostnamectl 设置主机名：
sudo hostnamectl set-hostname manager.example.com sudo hostnamectl set-hostname --transient manager.example.com sudo export HOSTNAME=manager.example.com
$ sudo hostnamectl set-hostname manager.example.com
$ sudo hostnamectl set-hostname --transient manager.example.com
$ sudo export HOSTNAME=manager.example.com
另外，director 还需要在
/etc/hosts 文件中包括一个带有系统主机名和基本名的项。例如，您系统的名称是 manager.example.com，/etc/hosts 则需要包括一个和以下类似的项：
127.0.0.1 manager.example.com manager
127.0.0.1 manager.example.com manager
