我已经部署了一个 6 个节点的 ceph 存储集群 + 1 个管理员和 1 个监视器。一切似乎都很好。我刚刚创建了一个网关节点，当我启动 ceph-radosgw 进程时它似乎很好：
[ceph@gwy001iad ~]$ sudo /etc/init.d/ceph-radosgw status
/bin/radosgw is running.
但我无法在其上使用任何 rados 或 rados-admin cmd。
[ceph@gwy001iad ~]$ sudo radosgw-admin user create --uid="testuser" --display-name="First User"

无法连接到集群！错误-2
密钥环文件具有读取权限：
[ceph@gwy001iad ~]$ ls -l /etc/ceph/
total 16
-rw-r--r-- 1 root root 252 Apr 21 17:14 ceph.client.radosgw.keyring
-rw-r--r-- 1 root root 121 Apr 20 17:53 ceph.client.radosgw.keyring.bk
-rw-r--r-- 1 root root 814 Apr 21 17:30 ceph.conf
drwxr-xr-x 2 root root 6 Apr 21 12:31 radosgw-agent
-rwxr-xr-x 1 root root 92 Apr 10 12:42 rbdmap
-rw------- 1 root root 0 Apr 21 11:57 tmpavz_Y7
并且配置确实指示了环文件的正确路径：
[ceph@gwy001iad ~]$ cat /etc/ceph/ceph.conf
[global]
mon_initial_members = mondev001iad
mon_host = 10.96.40.98
auth_cluster_required = cephx
auth_service_required = cephx
auth_client_required = cephx
filestore_xattr_use_omap = true
osd_pool_default_size = 2
osd pool default pg num = 100
osd pool default pgp num = 100
#debug ms = 1
#debug rgw = 20
[mon]
# mon host = mondev001iad
# mon addr = 10.96.40.98:6789
[mon.cldstoremondev001iad]
host = mondev001iad
mon addr = 10.96.40.98:6789
[client.radosgw.gwy001iad]
host = gwy001iad
keyring = /etc/ceph/ceph.client.radosgw.keyring
rgw socket path = ""
log file = /var/log/radosgw/client.radosgw.gateway.log
rgw frontends = fastcgi socket_port=9000 socket_host=0.0.0.0
rgw print continue = false
密钥环文件确实提供写权限。
[ceph@gwy001iad ~]$ cat /etc/ceph/ceph.client.radosgw.keyring
[client.radosgw.gwy001iad]
key = AQCl5jZVVu6NEBAAR3xNNAbDK9m0cQnlCG/+1w==
caps mon = "allow rwx"
caps osd = "allow rwx"
网关主机上只安装了 ceph-radosgw 和 radosgw-agent。如果有人可以为我提供故障排除提示，我将不胜感激。最好的祝愿。
