Spacewalk 错误：jabberd/c2s[4642]：不存在主机的 SASL 回调：abcd

我在 CentOS Linux 版本 7.4.1708 (核心) 上运行 spacewalk 2.6

并使用 spacewalk-service start 启动太空行走

我观察到：

jabberd.service - Jabber Server
   Loaded: loaded (/usr/lib/systemd/system/jabberd.service; enabled; vendor preset: disabled)
   Active: active (exited) since Wed 2018-02-28 16:24:06 UTC; 7h ago

 Main PID: 4644 (code=exited, status=0/SUCCESS)
   Memory: 0B

经过进一步调查和谷歌搜索

现在 spacewalk.abc 似乎是一个 aws 负载均衡器：

$nslookup spacewalk.a.b.c
Server:         1x.xx.xxx.80
Address:        1x.xx.1xx.80#53

spacewalk.a.b.c canonical name = internal-GSS-Spacewalk-123456789.us-east-1.elb.amazonaws.com.
Name:   internal-GSS-Spacewalk-123456789.us-east-1.elb.amazonaws.com

Name:   internal-GSS-Spacewalk-123456789.us-east-1.elb.amazonaws.com
Address: 1x.1xx.1xx.82

我搜索了论坛和博客，但找不到解决此 jabberd 无法启动的问题的方法

--------------- 回答@tukan ------------------------------------

jabberd 启动时实际上会运行 6 个程序。它们的可执行文件位于以下位置：

1. /usr/bin/c2s 
2. /usr/bin/jabberd 
3. /usr/bin/resolver 
4. /usr/bin/router 
5. /usr/bin/s2s 
6. /usr/bin/sm

jabberd configuration:

1. /usr/bin/c2s -c /etc/jabberd/c2s.xml        https://pastebin.com/A1Qp44qp
2. /usr/bin/jabberd itself does not have a config ??
3. /usr/bin/sm -c /etc/jabberd/sm.xml          https://pastebin.com/4gi4MR3g
4. /usr/bin/router -c /etc/jabberd/router.xml  https://pastebin.com/cdRZqk5D
5. /usr/bin/s2s -c /etc/jabberd/s2s.xml        https://pastebin.com/nPsMsde3
6. /usr/bin/sm -c /etc/jabberd/sm.xml          https://pastebin.com/s7vQu3VE

c2s and sm are configured to encrypt information that passes through them. The cert and key used to do this are located in the /etc/jabberd/server.pem file.

感谢您的配置。您的配置对我来说很好。您的配置文件中只有小写字母。

我认为您仍然可能会点击大写的主机名：

internal-GSS-Spacewalk-123456789.us-east

因为你nslookup的名字中有大写字母

$nslookup spacewalk.abc 服务器：1x.xx.xxx.80 地址：
1x.xx.1xx.80#53

spacewalk.abc 规范名称 = internal-GSS-Spacewalk-123456789.us-east-1.elb.amazonaws.com。名称：
internal-GSS-Spacewalk-123456789.us-east-1.elb.amazonaws.com 地址：1x.1xx.1xx.55 名称：
internal-GSS-Spacewalk-123456789.us-east-1.elb.amazonaws.com 地址：1x.1xx.1xx.82

尝试将您的 FQDN 全部小写，它应该会开始工作。我现在在手机上写作，稍后我会在笔记本上填写参考资料。

编辑正如承诺的那样，以下是来源：

如果主机名包含大写和小写，jabberd 和 osad/osa-dispatcher 之间的通信将失败

去引用：

“切勿在 Satellite 主机名中使用大写字母，否则会导致程序无法正常运行！”

在 CentOS7 上安装 Spacewalk 时出现问题（全新安装）

虽然听起来很奇怪，但您永远不应该在主机名中使用大写字母！
