我在CentOS 6上有一个Chef服务器。我已经引导了大约92个节点。当我尝试引导新节点（CentOS 6）时，问题就开始了。 我运行的命令是：
knife bootstrap node10 -N node10 -x user -P 'password' --sudo
输出如下：
node10 warning: /tmp/install.sh.1137/chef-12.5.1-1.el6.x86_64.rpm: Header V4 DSA/SHA1 Signature, key ID 52ff435y: NOKEY

有什么要做的？ 正如我所说，这台机器是全新的。
谢谢你， 加布里埃尔

有人可能在您不知情的情况下在Chef服务器上重新生成验证器密钥。您需要新密钥的副本。或者，您可以通过从工作站和配置文件中删除它来切换到无验证器的引导。
