大家好日子，
我已经设置了一个包含三个虚拟机的测试环境，以便能够部署ceph集群。 这些机器都与CentOS7 64bit相同。我在所有这些上安装了ceph，并在第一节上安装了ceph。我在ceph-node1上安装了初始监视器，但是当我尝试在ceph-node2上安装时，我收到一个错误，我无法通过它。我不知道如何解决这个问题。有什么想法吗？

最终解决方案应符合警告信息：
[ceph-node2] [WARNIN]未为监视器定义public_addr和public_network个键
所以解决方案是将public_addr添加到ceph.conf文件中，如下所示： public_network = 192.168.111.0/24

Ceph在虚拟服务器上表现不佳。我已经在VMWare上测试了Luminous and Mimic。您将无法获得裸机的相关结果（特别是对于I / O）...
对于以上错误，每个服务器上应该有2个网卡。您向客户展示的一个公共场所，以及供ceph重新平衡数据的一个私人场所。
还请记住在服务器上使用FQDN名称...

我在八达通中也遇到了同样的问题，因为我在node3上的mon容器不能以错误开头：
no public_addr or public_network specified, and mon.node3 not present in monmap or ceph.conf
不幸的是，我还没有弄清楚发生这种情况的真正技术原因，只是删除守护程序mon.node3
ceph orch daemon rm mon.node3 --force
，等到ceph重新创建它。
