Ejabberd：从客户端连接时无法启动 BOSH 会话

Ejabberd: Failed to start BOSH session when connecting from client

今天我将服务器从 Ubuntu 16.04 升级到 18.04，这也包括从 ejabberd 16.01 到 18.01 的跳转。现在我们从客户端连接时遇到问题（使用 strophe.js）

[info] <0.359.0>@ejabberd_listener:accept:302 (<0.876.0>) Accepted connection 127.0.0.1:60552 -> 127.0.0.1:8088

我知道 mod_http_bind 被 mod_bosh 取代了。客户端通过 apache 代理从端口 80 连接到 8088。请求 :80/http-bind/ 因此将被传递到 :8088/bosh/

升级后，我还完全擦除了 mnesia 数据库，以确保它没有损坏或被弃用。

，我还检查了是否启用了 curl。

在日志级别调试，mod_bosh 模块似乎已启动：

[debug] <0.329.0>@gen_mod:start_module:193 loading mod_bosh at jabber.myserver.com
[debug] <0.329.0>@gen_mod:start_module:193 loading mod_push at jabber.myserver.com

是否完全重新安装了 ejabberd：

apt-get --purge autoremove ejabberd

（确保/etc/ejabberd为空）

apt-get update
apt-get upgrade
apt-get install ejabberd

这里是ejabberd.yml的相关部分。我没有改变任何其他东西：

hosts:
  - "localhost"
  - "chat3.myserver.com" <- the public domain

listen:
  - 
    port: 5222
    ...
  -
    port: 5269
    ...
  -
    ##port: 5280
    port: 8088      <- use any port you like
    ip: "127.0.0.1" <- listen only on localhost
    module: ejabberd_http
    request_handlers:
      "/ws": ejabberd_http_ws
      "/bosh": mod_bosh
      "/api": mod_http_api
    ##  "/pub/archive": mod_http_fileserver
    web_admin: true
    ## register: true
    ## captcha: true
    tls: false  <- no need for tls on localhost
    protocol_options: 'TLS_OPTIONS'

auth_method: sql
sql_type: mysql
sql_server: "server"
sql_database: "ejabberd_live"
sql_username: "ejabberd"
sql_password: "secret"

acl:
  admin:
  user:
    - "": "localhost"
    - "admin": "chat3.myserver.com"

如果您想知道我在 apache 中的代理配置。这些是我的 chat3.myserver.com 虚拟主机的相关行：

ProxyPass /http-bind/ http://127.0.0.1:8088/bosh
ProxyPassReverse /http-bind/ http://127.0.0.1:8088/bosh
ProxyPass /admin/ http://127.0.0.1:8088/admin/
ProxyPassReverse /admin/ http://127.0.0.1:8088/admin/

您当然还需要获取 mysql 数据库模式 from here ... 等等...

我不知道是什么导致了连接错误。我猜 ejabberd 的升级是有问题的。至少我很确定这不是已知错误。我在互联网上爬了 4 个小时，但没有找到与这个版本的 ejabberd (18.01) 类似的东西。而且错误消息 - 即使在日志级别 5 下 - 也非常模糊。如果这是配置错误，我相信错误消息会更加具体。

您的配置中的问题似乎是您删除了 ejabberd_c2s 侦听器。它是必需的，您可以在错误消息中看到它。所以，问题是通过添加它来解决的，至少在我的情况下，例如：

listen:
  -
    port: 5222
    module: ejabberd_c2s
  - 
    port: 8088
    ip: "127.0.0.1"
    module: ejabberd_http
    request_handlers:
      "/bosh": mod_bosh
    web_admin: true
    tls: false

ejabberd文档中没有提到这样的需求，所以我现在添加了。
