我正在尝试设置 Ceph 集群。我有 4 个节点 - 1 个管理节点、1 个监视器和 2 个对象存储设备。我使用的安装指南位于以下位置：http://ceph.com/docs/master/start/quick-ceph-deploy/。
当我尝试添加初始监视器（指南中的第 5 步）时，出现以下错误：

“worker-1-full” 是我尝试设置为监视器的节点。我使用的命令是：
“ceph-deploy mon create-initial”。请帮忙。提前致谢！
答案1
我遇到了同样的错误，通过添加其他 ceph 节点解决了该问题主机名和 IpAdrress 并添加“public_network =”
我调整过的部分ceph.conf是：
mon_initial_members =
mon_host =
public_network =
猫/etc/ceph/ceph.conf
[global]
fsid = 33cb5c76-a685-469e-8cdd-fee7c98c3f4d
mon_initial_members = ceph1,ceph2
mon_host = 192.168.61.39,192.168.61.40
auth_cluster_required = cephx
auth_service_required = cephx
auth_client_required = cephx
filestore_xattr_use_omap = true
public_network = 192.168.61.0/24
并运行命令：
$ ceph-deploy --overwrite-conf mon create <ceph-node>
答案2
看来您的节点名称与其实际主机名不同，因此该文件/var/run/ceph/ceph-mon.worker-1-full.asok的名称不正确。我已更改主机名，这对我有用。
答案3
/var/run/ceph 目录是否存在？如果不存在，Ceph 可能无法创建 .asok（管理套接字）文件。
答案4
就我而言，这是由于前一个命令失败引起的，脚本没有检测到该命令：
# ceph-deploy mon create-initial
...
[ceph-server-1][DEBUG ] create the init path if it does not exist
[ceph-server-1][INFO ] Running command: systemctl enable ceph.target
[ceph-server-1][INFO ] Running command: systemctl enable ceph-mon@ceph-server-1
[ceph-server-1][INFO ] Running command: systemctl start ceph-mon@ceph-server-1
[ceph-server-1][INFO ] Running command: ceph --cluster=ceph --admin-daemon /var/run/ceph/ceph-mon.ceph-server-1.asok mon_status
[ceph-server-1][ERROR ] admin_socket: exception getting command descriptions: [Errno 2] No such file or directory
我journalctl -xe发现：
Jul 05 12:12:29 ceph-server-1.novalocal ceph-mon[27403]: 2019-07-05 12:12:29.389 7f7b5aed7180 -1 rocksdb: IO error: while open a file for lock: /var/lib/ceph/mon/ceph-ceph-server-1/store.db/LOCK: Permission denied
解决：
# chown -R ceph:ceph /var/lib/ceph/mon/ceph-ceph-server-1/store.db/
# chown ceph:ceph /var/lib/ceph/mon/ceph-ceph-server-1/keyring
现在我有一个快乐的 Ceph。
