我正在创建一个简单的 Ceph 集群并尝试连接到 Ceph 网关。
这是我的 Ceph 集群的 ceph 状态输出：
cluster:
id: a7f64266-0894-4f1e-a635-d0aeaca0e993
health: HEALTH_WARN

这是 /etc/ceph/ceph.conf 下的 Ceph 配置：
[global]
fsid = a7f64266-0894-4f1e-a635-d0aeaca0e993
mon_initial_members = rhcsa
mon_host = 192.168.122.61
public_network = 192.168.122.0/24
auth_cluster_required = cephx
auth_service_required = cephx
auth_client_required = cephx
osd_pool_default_size = 1
osd_pool_default_min_size = 1
osd_pool_default_pg_num = 333
osd_crush_chooseleaf_type = 1
[client.rgw.rhcsa]
host = rhcsa
rgw dns name = rhcsa
log file = /var/log/ceph/client.rgw.rhcsa.log
keyring = /var/lib/ceph/radosgw/ceph-rgw.rhcsa/keyring
rgw frontends = "beast port=8080"
我为 rgw 创建了以下目录：
/var/lib/ceph/radosgw/ceph-rgw.rhcsa
然后是钥匙圈：
sudo ceph-authtool --create-keyring /var/lib/ceph/radosgw/ceph-rgw.rhcsa/keyring
sudo chmod +r /var/lib/ceph/radosgw/ceph-rgw.rhcsa/keyring
sudo ceph-authtool /var/lib/ceph/radosgw/ceph-rgw.rhcsa/keyring -n client.rgw.rhcsa --gen-key
sudo ceph-authtool -n client.rgw.rhcsa --cap osd 'allow rwx' --cap mon 'allow rwx' /var/lib/ceph/radosgw/ceph-rgw.rhcsa/keyring
然后启动Ceph的RadosGW服务：
sudo systemctl restart [email protected]
RadosGW 服务似乎运行良好：
[root@rhcsa ~]# systemctl status [email protected]
● [email protected] - Ceph rados gateway
Loaded: loaded (/usr/lib/systemd/system/[email protected]; disabled; preset: disabled)
Active: active (running)
Main PID: 18501 (radosgw)

└─18501 /usr/bin/radosgw -f --cluster ceph --name client.rgw --setuser ceph --setgroup ceph
rhcsa systemd[1]: Started Ceph rados gateway.
但是，当我尝试从 8080 获取响应时，我什么也没得到：
[root@rhcsa ~]# curl http://localhost:8080
curl: (7) Failed to connect to localhost port 8080: Connection refused
我使用的是 Rocky Linux 9.2，Ceph 版本为 17.2.6 quincy/stable。
重新创建并重新激活 ceph-mgr 守护进程刚刚解决了问题，现在我可以从我的 RadosGW 端点获得响应。
