问题：gwcli.utils.GatewayAPIError：连接到 http://localhost:5001/api/config 的未知错误

问题描述

请帮助我，因为这让我不寒而栗。

根据文档[CONfigURING THE ISCSI TARGET USING THE COMMAND LINE INTERFACE](Configuring the iSCSI Target using the Command Line Interface — Ceph Documentation)，我已经安装了ceph-iscsi、python-rtslib、targetcli和tcmu-runner .当我尝试使用 gwcli 配置 iSCSI 目标时，我收到一些错误消息：

$[root@node1:~] gwcli -d
Adding ceph cluster 'ceph' to the UI
Fetching ceph osd information
Querying ceph for state information
Traceback (most recent call last):
  File "/usr/bin/gwcli",line 194,in <module>
    main()
  File "/usr/bin/gwcli",line 105,in main
    root_node.refresh()

  File "/usr/lib/python2.7/site-packages/ceph_iscsi-3.4-py2.7.egg/gwcli/gateway.py",line 99,in _get_config
  File "utils.py",line 451,in __getattr__
gwcli.utils.GatewayAPIError: UnkNown error connecting to http://localhost:5001/api/config

首先，我检查了这三个服务的状态：rbd-target-api、rbd-target-gw 和 tcmu-runner。他们都运行良好。然后，我尝试使用 curl 命令从 http://localhost:5001/api/config 获取配置信息，它也运行良好。配置信息如下：

[root@node1:~]$ curl --insecure --user admin:admin -X GET http://localhost:5001/api/config
{
  "created": "2021/07/12 07:45:31","discovery_auth": {
    "mutual_password": "","mutual_password_encryption_enabled": false,"mutual_username": "","password": "","password_encryption_enabled": false,"username": ""
  },"disks": {},"epoch": 0,"gateways": {},"targets": {},"updated": "","version": 11
}

这里有些奇怪。这里有一些奇怪的东西。从控制台消息来看，gwcli 命令执行失败，但从 /var/log/rbd-target-api/rbd-target-api.log 中打印的日志消息来看，该命令似乎执行得很好。 rbd-target-api.log 如下所示。

如上所示，rbd-target-api 守护进程可以接收来自 gwcli 的获取配置请求。 http 状态代码是 200，守护进程也生成了配置对象。 gwcli 好像出了点问题？

另外，我也尝试过重启rbd-target-api服务，但是没有任何改变。

我的环境如下：

操作系统：Centos 7 Linux 5.11.16-1.el7.elrepo.x86_64 x86_64
应用版本：
- ceph-iscsi：3.4-1.el7
- gwcli：2.7
- tcmu-runner: 1.4.0-rc1
- python-rtslib：2.1.74-1.el7_9

我的 iscsi-gateway.cfg 如下所示，我确保此文件已复制到 node1、node2 和 node3。 node1、node2和node3是三个远程服务器。

$ cat /etc/ceph/iscsi-gateway.cfg 
[config]
# Name of the Ceph storage cluster. A suitable Ceph configuration file allowing
# access to the Ceph storage cluster from the gateway node is required,if not
# colocated on an OSD node.
cluster_name = ceph

# Place a copy of the ceph cluster's admin keyring in the gateway's /etc/ceph
# drectory and reference the filename here
gateway_keyring = ceph.client.admin.keyring

# API settings.
# The API supports a number of options that allow you to tailor it to your
# local environment. If you want to run the API under https,you will need to
# create cert/key files that are compatible for each iSCSI gateway node,that is
# not locked to a specific node. SSL cert and key files *must* be called
# 'iscsi-gateway.crt' and 'iscsi-gateway.key' and placed in the '/etc/ceph/' directory
# on *each* gateway node. With the SSL files in place,you can use 'api_secure = true'
# to switch to https mode.

# To support the API,the bear minimum settings are:
api_secure = false

# Additional API configuration options are as follows,defaults shown.
api_user = admin
api_password = admin
api_port = 5001
trusted_ip_list = node1,node2,node3

这个问题困扰我好几天了。谁能给我一些提示或建议？

提前致谢。
