红帽全球峰会7.2. 配置主红帽网络 Satellite 服务器
要使用 satellite 间同步功能，您必须首先保证启用了该功能。保证
/etc/rhn/rhn.conf 包含以下行：
disable_iss=0
在同一文件中是变量：
allowed_iss_slaves=
默认情况下不指定要与主服务器同步的辅助 Satellite，因此您必须输入每个辅助 Satellite 服务器的主机名，用逗号分开。例如：
allowed_iss_slaves=slave1.satellite.example.org,slave2.satellite.example.org
完成配置
rhn.conf 文件后，输入以下命令重启 httpd 服务：
service httpd restart
